What do you need to know if you or a loved one has been diagnosed with follicular lymphoma? 

Follicular lymphoma is a type of B-cell non-Hodgkin lymphoma. It is typically slow-growing and can begin in the lymph nodes, bone marrow, or other organs. The disease does not always cause symptoms. But if symptoms are present, they can include swollen lymph nodes, fever, unintentional weight loss, and night sweats.  

Follicular lymphoma is classified as “low grade” if the disease is slow-growing, or “high grade,” if the disease is more aggressive and growing more rapidly. 

Follicular lymphoma is staged to understand where the lymphoma is in the body and to help determine which treatment options are best. There are four stages – 

  • Stage I, in which the lymphoma is localized in one single lymph node area or one non-lymph node site. When there is a non-lymph node site involved, an “E” is added to the stage, meaning “extra nodal.” 
  • In stage II, the lymphoma is in two or more areas on one side of the diaphragm. Again, “E” designation means that there is a non-lymph node site involved. 
  • Stage III means the lymphoma is in two or more lymph node areas above and below the diaphragm. 
  • And finally, stage IV is when the lymphoma is widespread, with involvement above and below the diaphragm, including at least one non-lymph node site. 

Unlike in many other types of tumors, stage IV follicular lymphoma is often very treatable, because lymphomas tend to be sensitive to many different therapies. 

Treatment recommendations are based on a variety of factors, including: 

  • Disease stage 
  • Tumor size and tumor grade 
  • Disease symptoms 
  • And a patient’s age and overall health 

For some patients, treatment doesn’t begin right away, and an approach called “watchful waiting,” “observation,” or “active surveillance” is used to monitor the progression of the disease. This usually involves regular oncology clinic visits and lab checks – and sometimes repeat imaging scans. 

When it is time to treat, options may include: 

  • Radiation therapy 
  • Chemotherapy 
  • Targeted therapy 
  • Immunotherapy 
  • Or cellular therapy, such as CAR T-cell therapy or a bone marrow transplant.
  • Your physician may also recommend clinical trial options. 

Now that you understand more about follicular lymphoma, how can you take an active role in your care?  

  • First, continue to educate yourself about your condition. Ask your healthcare team to recommend credible resources of information.  
  • Next, understand the goals of treatment and speak up about your personal preferences.
  • Consider a second opinion or a consult with a specialist following a diagnosis to confirm your treatment approach.
  • And, write down your questions before and during your appointments. Visit powerfulpatients.org/FL to access office visit planners to help you organize your thoughts. Bring loved ones to your appointments to help you recall information and to keep track of important details.
  • Ask your doctor whether a clinical trial might be right for you.
  • Finally, remember that you have a voice in your care. Don’t hesitate to ask questions and to share your concerns. You are your own best advocate.

Transcript:

Katherine:

Okay, that’s great. Here’s one from Phil, “How do mutations affect longevity when surviving CLL? What new treatments help with P53 mutation?”  

Dr. Bhat:

So, there are certain prognostic markers for CLL, meaning certain tests that can tell us how a particular patient is expected to do. Some of these tests detect presence or absence of mutations in certain genes. For example, the IGHV gene can be mutated or unmutated. 

In patients with mutated IGHV, they do well, and patients with unmutated IGHV tend to have a more aggressive disease and may require treatment sooner. Similarly, TP53 mutations also tend to require treatment sooner, and more of these mutations do not respond well to conventional chemotherapy. However, targeted therapy has changed the outlook for these mutations, and it works very well for both these mutations.

Katherine:  

Dr. Bhat, where do clinical trials fit into treatment? 

Dr. Bhat:  

So, clinical trials play a very important role to advance treatments. Clinical trials for CLL are done to test new treatments, new combinations of treatments, compare different treatments to each other. The goal of these clinical trials is to continue to do better than what we currently have available. This is how treatments improve. Despite all the advancements that we have had in CLL, in the recent years, it continues to be an incurable disease, even today. Our goal as researchers is never to stop until we get to that cure, and clinical trial is that pathway to that cure.

Katherine:

Are there emerging therapies that are showing promise? 

Dr. Bhat:

Yes, of course. There are a number of emerging therapies that are showing promise. So, we all know about ibrutinib and other BTK inhibitors. These work very well, but sometimes the disease can get resistant to these medications, meaning that it stops responding to these treatments. We are excited about this new kind of BTK inhibitor called, “pirtobrutinib,” which has shown great promise in these resistance cases, and we are hopeful that it’ll be approved soon. 

Katherine:

Are there other options that patients have? 

Dr. Bhat:

So, we all hear about what is called, “chimeric antigen receptor T-cell therapy,” or CAR-T therapy. This is studied under clinical investigation for CLL and looks very promising. The therapy uses the person’s own immune cell called, “T cell” to identify and attack cancer cells. 

T cells are taken from the patient’s blood and sent to a specific lab. There, the cells are modified so that they can better find and attack cancer cells. These modified T cells are then re-injected back into the patient to find and fight that cancer, to eradicate the disease. So, this looks very promising.

Managing CLL Symptoms and Treatment Side Effects

Transcript:

Katherine Banwell:

Dr. Bhat, when it’s time to start therapy, what types of treatments are available for CLL patients? 

Dr. Bhat:

So, when we think about treatment for cancer, we think about chemotherapy – the conventional chemotherapy that’s associated with side effects like hair loss, nausea, or vomiting. I’m very happy to say that conventional chemotherapy is no longer the standard of care for patients with CLL. Patients who need treatment for CLL are nowadays treated with what are called, “targeted agents.” 

And we have, in general, two different classes of targeted agents that have been approved for treatment for CLL. We have the BTK inhibitors, Bruton’s tyrosine kinase inhibitors, of which we have three. We have ibrutinib, we have acalabrutinib, and we have zanubrutinib. Then we have BCL-2 inhibitors, of which we currently have one approved, of which is called venetoclax. These treatments can be combined with monoclonal antibodies, which are directed towards the antigen called CD20. For example, rituximab or obinutuzumab. 

Typically, venetoclax is combined with monoclonal antibody as a time-limited therapy. BTK inhibitors usually are not combined with monoclonal antibody. 

Katherine:

What about stem cell transplant, does that fit in there? 

Dr. Bhat:

So, stem cell transplant still has a role for treatment of patients with CLL, but it has moved down the line with such highly effective and well-tolerated oral agents available. 

But, for refractory patients – what we call dual-refractory patients, we definitely are, especially in high – patients who have higher risk features, we do refer them to stem cell transplant. 

Katherine:

And what is a dual-refractory patient, exactly? 

Dr. Bhat:

Dual-refractory patients mean patients who have had a BTK inhibitor, be it ibrutinib, acalabrutinib, or zanubrutinib, and the disease has progressed on that. And then we give them venetoclax, which is a BCL-2 inhibitor. So, these are the two classes of targeted agents that we have available. If they have received ibrutinib, acalabrutinib, or zanubrutinib, and after that, a venetoclax, or venetoclax followed by a BTK inhibitor, and the disease has progressed on both. These patients are called dual-refractory, and currently they tend to be very resistant to whatever treatments we have available. And we looked at other modalities of treatment, be it clinical trials or stem cell transplants for that.

Emerging DLBCL Treatments That Patients Should Know About


Transcript:

Katherine:

What are the side effects that patients can expect with these treatments?  

Dr. Maddocks:

So, when they get the treatment, on the day they get it, there can be an infusion reaction to the rituximab or antibody therapies. So, the first treatment, that treatment is given very slowly and titrated up. If patients have a reaction, we stop it, treat the reaction, and then they’re able to continue therapy but again, that first day, it can take several hours for that one antibody to get in. And then, later, therapies are given at a more rapid pace.   

So, about 70 percent of people who react, it can be really almost anything. Some people get flushing, some people will get a fever, some people –have shortness of breath or their heart rate will go up. 

Katherine:

Okay. All right. Any other side effects? 

Dr. Maddocks:

Yeah. So then chemotherapy is meant to kill cells during the cell cycle. So, cancer cells divide more rapidly, chemotherapy is targeting them, but it also effects good cells in the body, specifically those that divide at a more rapid pace. The biggest risk of chemotherapy is infection.  

So, it effects the good white blood cells that fight infections. It can affect your red cells that carry your iron, gives you your energy. Or your platelets which help you to clot or not bleed when you get caught. So, infection is the biggest risk of chemotherapy. So, usually, with this regimen, that infectious risk is highest within the second week of treatment, that treatment is given every three weeks.  

So, we tell patients they should buy a thermometer, check their temperature, they have to notify their doctor or go to the ER if they have a fever. Besides infection, there’s a small percentage of patients who might need a transfusion. GI toxicity. So, nausea, vomiting, diarrhea, mouth sores, constipation, all of which we have good treatments for. So, we give medication before chemo to try to prevent people from getting sick and then give them medicine to go home with, if they have any nausea. We can alter those medications as time goes on, if they’re having any problems. So, we just need to know about it. Most patients will lose their hair with this regimen.  

It can affect people’s tastes, it can make their skin more sensitive to the sun, and then, less common but potential side effects are it can cause damage to the nerves. Or something we call neuropathy, which most often patients will start with getting numbness or tingling in their fingers and toes, and we can dose adjust if that’s causing some problems.  

And then, there’s a risk to the heart with one of the drugs. So, the heart should pump like this. The heart pump function can go down. So, we always check a patient’s heart pump function before they get their chemo, to make sure that they’re not at higher risk for that to happen.  

Katherine:

So, all of these approaches are used in initial treatment?  

Dr. Maddocks:

Mm-hmm. 

Katherine:

Okay.

A DLBCL Expert Debunks Common Patient Misconceptions


Transcript:

Katherine:

Have there been any recent developments in how DLBCL is treated?  

Dr. Maddocks:

There had been recent developments. So, the CAR T-cell therapy, there is now three approved options for patients. And so, even patients who maybe are older and not considered candidates for a stem cell transplant because of other medical factors, might be able to get the CAR T-cell therapy. This is now, again, approved in the second line. There are a couple antibody drug conjugates, polatuzumab and loncastuximab, they target proteins called CD-79 and CD-19.  

And the polatuzumab’s the one that probably is going to be available for part of the front-line treatment in the future. There’s the antibody tafasitamab and lenalidomide. These are all approved therapies in the relapse setting. There are also therapies that are being studied and showing promising activity, which we think are probably likely to be approved in the future. There’s something particularly called bi-specific antibodies.  

So, this targets a protein on the tumor cell but also a protein on the T cell. So, remember I said the T cells aren’t functioning. So, this targets the protein on the lymphoma cell but then targets a protein on the T cell to engage it to attack the lymphoma cell. 

Katherine:

Right. Combination approaches?   

Dr. Maddocks:

Yeah. So, there are a number of combination approaches under study a lot of the therapies that I mentioned, like the bi-specific antibodies, the antibody drug conjugates. These are all therapies that – they have side effects – I hate to say they’re well-tolerated – they have side effects but their side effects are such that they can be combined with other agents, that have different toxicities that are combined with each other. And so, there’s a lot of ongoing trials looking at combining these. There’re also oral targeted therapies that target proteins that are known to help the lymphoma cells survive and these are modulator therapies, BTK inhibitors, other inhibitors, that are being evaluated and used in combinations.  

Katherine:

Thanks, Dr. Maddocks. That’s really helpful information.

Transcript:

Katherine:

So, how do you know if a treatment is working?  

Dr. Maddocks:

So, as far as evaluating treatment, you get a scan before you start treatments, so we know where all the lymphoma is at. And then, typically, you get some sort of scan in the middle of treatment, and then after, you complete your six cycles of treatment. Or for early stages, sometimes patients will get less than six cycles. So, we get scans to make sure it’s working. So, you can tell by those things, how much has gone, hopefully all of it has gone by the end. Occasionally, patients that had a lot of symptoms to start with, their symptoms will go away, and then they’ll start coming back.  

This is less common, because the majority of patients do respond to chemotherapy. It’s less common to get patients who are what is called refractory, meaning they don’t get any response to therapy. So, occasionally they’ll note symptoms but a lot of times, we’ll see something on that mid-therapy or end of therapy scan, if it’s not going to make it all go away.  

Katherine:

So, if a treatment doesn’t work, what happens then?  

Dr. Maddocks:

If treatment doesn’t work, it depends a little bit – and now it depends a little bit on the timing of that treatment not working. So, it used to be that patients who were eligible for treatment, no matter if it didn’t work right away or if it put them into what we call a remission, so there’s no evidence of disease and then it relapsed, they would have the option of further chemotherapy and then an autologous stem cell transplant. So, a bone marrow transplant where they donate their own cells.  

If they were in a good enough health or if they were not – to do that, you have to donate your own bone marrow cells and as we age, we make less bone marrow cells. So, once you reach a certain age, your body can’t produce enough cells to donate to a transplant. In those patients, we offer them less aggressive chemo options, which were not known to be curable but could put them into remission again, for a while. More recently, there has been some that chimeric antigen receptor T-cell therapy that I mentioned where you actually donate your own T cells. So that’s –. And your lymphoma is of your B cells.  

Your T cells are in another immune cell that should recognize that lymphoma is bad and attack it, and they’re not functioning properly. So, you donate your own T cells, and they’re sent off and reengineered to target a protein on the tumor. Then, you get those cells back, and they’re meant to target the lymphoma and kill the lymphoma cells.  

So, that is now an approved therapy for patients who don’t achieve the remission – so, who’s first chemo doesn’t work or if they relapse within a year of completing chemo. So, that’s a possibility. The chemo and transplants a possibility. Or there’s other approved therapies now, that can be given as second options or third or later options, which have been shown to keep patients in remission for a while.  

Katherine:

Dr. Maddocks, you touched up on this a moment ago, but what are the approaches if a patient relapses? What do you do?   

Dr. Maddocks:

So, you would rework them up if they relapsed. Similar to that, if they relapse within a year and they have access to the CAR-T and they’re healthy for that, then that’ll be an option. The second type of chemotherapy in the transplant. So, you can’t just go straight to a transplant. You have to get a different type of chemotherapy to try to get the disease under control again, before you would go to a transplant.  

Or there’s a number of other targeted therapies that are approved. So, there’s other – I talked about rituximab (Rituxan) is given in the first line, that targets a CD-20 protein, there’s an antibody that targets a CD-19 protein that’s given out in relapse. There’s another antibody drug – there’s actually two antibody drug conjugates. So, an antibody that targets the protein on the cells that are attached to a chemo, that’s given. Or there’s different chemotherapy and then even some oral therapies.  

Katherine:

Okay. So, there’s a lot of different options available for people.  

Dr. Maddocks:

Correct. And there’s always clinical trials. So, there’s always the option to find something where we’re studying some of these newer therapies. They’re therapies in combination.

What Do Patients Need to Know About DLBCL and COVID Vaccines


Transcript:

Katherine:

Let’s turn to treatment options. Is a person with DLBCL treated right away?  

Dr. Maddocks:

They’re treated pretty quickly after the diagnosis. So, typically, when somebody has a diagnosis, they undergo a number of different tests, including lab work, imaging work, sometimes for their biopsies.  

So, that information is gathered over days to sometimes a few weeks process. Then, when you have all that information, you go over the results, go over the treatment at that time. So, it’s typically treated not within, usually, a day of diagnosis but it’s not something that you spend weeks or months before treating.  

Katherine:

Yeah. What are the different types of treatments available?  

Dr. Maddocks:

So, the diffuse large B-cell lymphoma is treated with chemotherapy and immunotherapy. So, a combination of an immune antibody therapy and chemotherapy. There is a role in some cases for radiation, but never just radiation alone and never just surgery alone. So, there’s always what we call a systemic treatment so, a treatment that goes everywhere. Because this is considered a blood cancer, it’s a cancer of those cells, it can really spread anywhere.  

And so, just cutting it out with surgery or just radiating the area doesn’t treat everything, even if you can’t identify it.  

Katherine:

Can you get specific about some of the treatment classes?   

Dr. Maddocks:

Yeah. So, the most common treatment for diffuse large B-cell lymphoma is a chemo immunotherapy called R-CHOP. So, this is three chemotherapies and antibody therapy that’s direct called rituximab (Rituxan) that’s directed at a protein on the lymphoma cells. And then, a steroid called prednisone, given with the chemo and then for a few days after. There was a study that recently showed an improvement with switching one of those drugs with another immunotherapy that’s an antibody conjugated to a chemo drug. But that’s not yet been approved. There are clinical trials available. So, looking at these treatments that might be new or combining therapies with this standard treatment.  

And then, very occasionally, there are certain features of diffuse large B-cell lymphoma. There are particular few different subtypes that are classified a little bit differently, that are treated within an infusional therapy called Dose Adjusted R-EPOCH.  

Katherine:

What about stem cell therapy? Is that used?  

Dr. Maddock:

Stem cell therapy is used in the relapse setting. So, if a patient doesn’t go into a remission or if they relapse after achieving a remission with their chemotherapy, then stem cell transplant is an option. So, there are actually two different types of stem cell transplant. One from yourself and one from somebody else. In lymphoma, we typically do one from yourself, where you donate your own cell before. But we don’t use that as part of the initial treatment.   

Katherine:

So, if somebody is high risk, Dr. Maddocks, is the approach different for them? 

Dr. Maddocks:

So, it depends. We define high risk in different ways. So, there’s a specific type of lymphoma called double hit lymphoma, where there’s a few chromosomal translocations associated with the lymphoma, that we give a little more aggressive chemo immunotherapy regimen. There are also other subtypes, including a rare type of lymphoma called primary mediastinal B-cell lymphoma. Again, categorized a little bit different but sometimes included as a large cell lymphoma. We also give that treatment for.   

Katherine:

Okay. So, there’s a lot of different options available for people.  

Dr. Maddocks:

Correct. And there’s always clinical trials. So, there’s always the option to find something where we’re studying some of these newer therapies. They’re therapies in combination.   

Katherine:

Is a cure possible?  

Dr. Maddocks:

Yes. A cure is possible. When you look at patients who are treated with initial chemotherapy, we cure somewhere between 60 percent to 70 percent of patients with the initial chemotherapy. If patients’ relapse, depending on their age and their condition, they’re candidates for other therapies.  

And therapy including other chemo and stem cell transplant is potentially curable in some patients. And then, there’s a newer therapy called chimeric antigen receptor T-cell, or CAR T-cell therapy, which also looks like it’s curing a subset of patients who relapse or don’t respond to initial therapy.

Katherine:

Hello, and welcome. I’m Katherine Banwell, your host for today’s program. Today’s webinar is part of our Thrive series, and we’re going to discuss tools for navigating life with CLL. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice. Please refer to your healthcare team about what might be best for you.  

Let’s meet our guest today. Joining us is Dr. Seema Bhat. Dr. Bhat, welcome. Would you please introduce yourself? 

Dr. Bhat:

Hi, Katherine. Thank you for having me here on the program. My name is Seema Bhat, and I am an associate professor at Ohio State University with expertise in treating CLL.  

Katherine:

Excellent, thank you so much for taking time out of your schedule to join us. 

Dr. Bhat:

You’re welcome. 

Katherine:

Like all of the webinars in our Thrive series, we start with this question. In your experience, what does it mean to thrive with CLL? 

Dr. Bhat:

So, thriving with CLL to me means that we envision our patients with CLL leading normal, functional, and productive lives. You know, when patients hear the word “cancer,” or “leukemia,” it comes as a big shock to them. Cancer is also associated with drastic changing – life-changing experiences. Patients think about their shortened life span, and the difficulties they’ll have to endure in this shortened life span due to the treatments they will be needing for their cancer. But I want to tell my patients that even though they have a leukemia, they have a cancer, they can still focus on their life in general. 

They have – this has been made possible by very effective yet gentle treatments approved for CLL. Patients can have an enjoyable, fulfilling life focusing on their life in general, and thrive. 

Katherine:

Thank you for that, Dr. Bhat. That’s important for patients to know. Let’s move on to treatment and walk through CLL treatment classes and types. Some of our audience members may already know this information, but it’s a good baseline for newly diagnosed patients. First, CLL patients are often put in “watch and wait” when they’re first diagnosed. What does that mean? 

Dr. Bhat:

So, “watch and wait” means observation. CLL is a slow-growing cancer, generally, and one of the few cancers that’s managed by observation if it’s not causing any problems to the patient. These problems could include symptoms in the form of fatigue, unintentional weight loss, symptomatic enlargement of their lymph nodes or spleen, or we could see changes in their blood work in the form of decreased hemoglobin or decreased platelets. 

If this is not happening, observation is still the standard of care. And data from this comes from a number of clinical trials where patients were treated based on just having the disease without having any of the symptoms or signs I just mentioned. 

All these studies had negative results, meaning that starting treatment at diagnosis did not affect the overall survival of these patients. These patients – these studies were, however, done in chemoimmunotherapy era. Now, we have targeted agents. And also, now we are able to define CLL better, which means that we are able to predict who has higher risk disease. 

So, there’s renewed interest in these – what these are called, early intervention studies. But until we have those results are matured and available, “watch and wait” is still the standard approach. And during “watch and wait,” we see patients at regular intervals, we assess them for symptoms, we look at their bloodwork, and one of the main reasons for seeing these patients at regular intervals is to reinforce what symptoms we want them to pay attention to. So, educating patients at each visit is a very important part of these visits. 

“Watch and wait” may be all that 1/3 of our patients may need through their lifetime. They may never need any CLL-directed treatment. 

Katherine:

Dr. Bhat, when it’s time to start therapy, what types of treatments are available for CLL patients? 

Dr. Bhat:

So, when we think about treatment for cancer, we think about chemotherapy – the conventional chemotherapy that’s associated with side effects like hair loss, nausea, or vomiting. I’m very happy to say that conventional chemotherapy is no longer the standard of care for patients with CLL. Patients who need treatment for CLL are nowadays treated with what are called, “targeted agents.” 

And we have, in general, two different classes of targeted agents that have been approved for treatment for CLL. We have the BTK inhibitors, Bruton’s tyrosine kinase inhibitors, of which we have three. We have ibrutinib (Imbruvica), we have acalabrutinib (Calquence), and we have zanubrutinib (BGB-3111). Then we have BCL-2 inhibitors, of which we currently have one approved, of which is called venetoclax (Venclexta). These treatments can be combined with monoclonal antibodies, which are directed towards the antigen called CD20. For example, rituximab (Rituxan) or obinutuzumab (Gazyva). 

Typically, venetoclax is combined with monoclonal antibody as a time-limited therapy. BTK inhibitors usually are not combined with monoclonal antibody. 

Katherine:

What about stem cell transplant, does that fit in there? 

Dr. Bhat:

So, stem cell transplant still has a role for treatment of patients with CLL, but it has moved down the line with such highly effective and well-tolerated oral agents available. 

But, for refractory patients – what we call dual-refractory patients, we definitely are, especially in high – patients who have higher risk features, we do refer them to stem cell transplant. 

Katherine:

And what is a dual-refractory patient, exactly? 

Dr. Bhat:

Dual-refractory patients mean patients who have had a BTK inhibitor, be it ibrutinib, acalabrutinib, or zanubrutinib, and the disease has progressed on that. And then we give them venetoclax, which is a BCL-2 inhibitor. So, these are the two classes of targeted agents that we have available. If they have received ibrutinib, acalabrutinib, or zanubrutinib, and after that, a venetoclax, or venetoclax followed by a BTK inhibitor, and the disease has progressed on both. These patients are called dual-refractory, and currently they tend to be very resistant to whatever treatments we have available. And we looked at other modalities of treatment, be it clinical trials or stem cell transplants for that. 

Katherine:

How are targeted therapies administered? 

Dr. Bhat:

So, most of the targeted therapies that we have, we are happy to say that these are oral agents. The BTK inhibitors, the three that we have available, are oral agents. Ibrutinib is taken once a day, zanubrutinib and acalabrutinib are twice a day. Venetoclax, similarly, is an oral agent and is taken once a day. Monoclonal antibodies are also considered targeted agents. These are given as infusions in the clinic or in the clinician’s office.  

Katherine:

The oral medications, patients take that at home? They don’t have to go into the hospital? 

Dr. Bhat:

They do not have to go into the hospital. However, venetoclax is associated with a specific side effect called, “tumor lysis syndrome,” where this medication works so well that initially the cells with die off quickly and then things can collect in the blood.  

For example, uric acid can go up, electrolytes can be up, any number can go up. So, we monitor what those initial weeks of starting venetoclax, we monitor patients very closely. We have them come back and forth to the clinic for monitoring, bloodwork, maybe hydration. And sometimes, if we think they’re at a very high risk for this tumor lysis syndrome, we admit them to the hospital.  

Dr. Bhat:

After we cross that, those are administered at home. They can take these at home. 

Katherine:

Dr. Bhat, where do clinical trials fit into treatment? 

Dr. Bhat:

So, clinical trials play a very important role to advance treatments. Clinical trials for CLL are done to test new treatments, new combinations of treatments, compare different treatments to each other. The goal of these clinical trials is to continue to do better than what we currently have available. This is how treatments improve. Despite all the advancements that we have had in CLL, in the recent years, it continues to be an incurable disease, even today. Our goal as researchers is never to stop until we get to that cure, and clinical trial is that pathway to that cure.  

Katherine:

Are there emerging therapies that are showing promise?  

Dr. Bhat:

Yes, of course. There are a number of emerging therapies that are showing promise. So, we all know about ibrutinib and other BTK inhibitors. These work very well, but sometimes the disease can get resistant to these medications, meaning that it stops responding to these treatments. We are excited about this new kind of BTK inhibitor called pirtobrutinib which has shown great promise in these resistance cases, and we are hopeful that it’ll be approved soon. 

Katherine:

Are there other options that patients have? 

Dr. Bhat:

So, we all hear about what is called, “chimeric antigen receptor T-cell therapy,” or CAR-T therapy. This is studied under clinical investigation for CLL and looks very promising. The therapy uses the person’s own immune cell called, “T cell” to identify and attack cancer cells. 

T cells are taken from the patient’s blood and sent to a specific lab. There, the cells are modified so that they can better find and attack cancer cells. These modified T cells are then re-injected back into the patient to find and fight that cancer, to eradicate the disease. So, this looks very promising. 

Katherine:

Many CLL community members are interested in learning more about their disease. So, for newly diagnosed patients, what are a few educational resources you recommend to help them learn more about their condition? 

Dr. Bhat:

There are a number of well-established support groups or educational resources for our patients. These include the CLL Society, The Leukemia & Lymphoma Society, Lymphoma Research Foundation, and then we have Patient Empowerment Network, and we have Patient Power. All these resources provide support groups, organize webinars, and have educational material for our patients. 

Katherine:

What about patients who have been living with CLL for many years, or are quite knowledgeable about their disease? Are there more advanced resources for patients to stay up to date on the latest research and treatment? 

Dr. Bhat:

So, for patients who want to search for additional resources, especially looking for clinical trials, going on this website called clinicaltrials.gov, they can first search for CLL-related clinical trials. Also, NCCN, or “National Comprehensive Cancer Network,” has patient resources for each disease, and then they can find information on CLL there, also. I would also like to say that Google is a good resource, as long as you know where it is taking you. 

Katherine:

Exactly. You may not be able to rely on everything you find. 

Dr. Bhat:

Right.  

Katherine:

Yeah. Many people with CLL will experience fear and anxiety, whether it’s the stress of being in “watch and wait” or worrying about regression. Why do you feel it’s important for patients to share how they’re feeling with their healthcare team? 

Dr. Bhat:

So, one of the important things to know about CLL is that CLL, at this point of time, it’s not a curable disease. It is a lifelong disease. Patients will have to deal with CLL for the rest of their life in some form or other, either on watchful waiting, or on active treatment, or if they’ll complete a treatment, they’ll have this lurking fear of relapse at any time. A large part of what I do is to help my patients understand what it means to live with CLL. And, of course, anxiety is a big part of that living with CLL. 

Although at this time, we’re unable to cure our patients with CLL, I want my patients to understand that it’s very treatable, treatments are very well-tolerated with low toxicity, and patients live a long life. They can have good, productive, and active life. They should ask their care team about resources for social, emotional, and physical support. 

They should let them know about their concerns, talk about their feelings. 

Katherine:

That’s my next question, actually. How can a social worker provide support and are there other healthcare team members who might be able to help? 

Dr. Bhat:

So, yes, patients are on a rollercoaster – emotional rollercoaster with this diagnosis. With this diagnosis come lots of unknowns. Worries about possible shortened life span, anxiety over treatment, and effects of treatment. So, there’s lots to deal with, and lot of uncertainty, which causes a feeling of hopelessness for these patients. So, psychological support is very important. That’s where the role of social worker comes in. 

We get them involved to help patients deal with the diagnosis, and social workers – they can provide patients with tools to cope with this life-changing event. They use life tools like encouraging positive thinking, mindfulness, being aware of what the patient can control involving faith and family, and also involving self-care. 

That’s where we see the role of the whole team as such. If patients are having more difficulties, we can have other members of a team, like a mental health provider, connect with our patients. Social workers and other members of the team can help our patients get connected to support groups, or even to other patients who have had similar experiences. 

Katherine:

What about worry and anxiety related to COVID and compromised immunity? What would you like patients to know? 

Dr. Bhat:

So, COVID has become another source of anxiety, unfortunately, for many of our patients, and rightly so. Our patients with CLL are considered immunocompromised, meaning that their immune systems do not work that well, which makes these patients very susceptible to different kinds of infections, COVID being one of them. And this was actually shown by some of the early COVID-related studies that showed a very high mortality in patients with CLL. 

This has improved now, mostly because now we are better equipped to handle COVID. We have COVID-directed medications available, but the major impact has been made by the vaccines. So, we highly encourage our patients to get vaccinated against COVID and keep up to date with the latest CDC guidelines. Also, we have Evusheld available, which is under emergency use authorization, and our patients with CLL, due to their weaker immune system, are eligible to get this, which adds an extra layer of protection for our patients. 

Also, it’s important to know that our test – if our patients test do test positive for COVID, they should let their team of doctors know immediately, since now we have monoclonal antibodies and pills that can be used to treat symptomatic COVID. 

Katherine:

That’s great information, thank you. Financial concerns can be another source of stress for people with CLL. Obviously, everyone’s situation is different, of course, but what resources are available for patients who need financial support?  

Dr. Bhat:

So, financial barriers can be a real concern for our patients. Targeted therapies are very expensive, and although insurances do cover them, the approved FDA drugs, copays can be very high, and this adds on because our patients with – our treatments with CLL, some of them tend to be indefinite. That means patients have to take those medications on an ongoing basis, and when they face such situations, high copays, we look into financial assistance. We look for funding for copay assistance, and funding can be provided by pharmaceutical companies. We can also apply for grants through The Leukemia & Lymphoma Society and other resources to help out our patients with these financial concerns. 

Katherine:

So, does the patient work with the healthcare team to find financial support? 

Dr. Bhat:

Absolutely. We at our institution have what is called, “MAP,” or Medication Assistance Program. 

And when we see that – we run the medications through the insurance, then we see the copay is high, we refer our patients to the MAP program, and then they take over. They find them grants, they find them assistance through be it pharmaceuticals, copay assistance programs. So, invariably, almost all patients who come and see us are helped through that program.  

Katherine:

What about a nurse navigator or patient navigator? What do they do? How can they help? 

Dr. Bhat:

Well, so yes. Nurse navigators and patient navigators are also very important for caring for our patients. So, patients can have, besides our care for our patients which includes caring for their disease, caring for their symptoms, caring for their reduced hemoglobin and reduced platelets, our symptom management, they have psychological needs, they have functional needs, they have needs like family support.  

So, these are all the things that patient navigators can help patients set that up based on their – we have patients who travel from out of state, are from two or three hours away. So, these patient navigators look into what resources they should have available locally. Sometimes, patient navigators help us – some patients cannot do frequent travels back and forth, so we get them connected to local oncologists, also. So, patient navigators look into those appointments, look into those offices, so they provide a lot of help to us manage our patients. So, they provide more of a holistic management, rather than just treatment of CLL. 

Katherine:

Let’s answer a few audience questions that we received in advance of the webinar. This one is from William. Can you please talk about common side effects of CLL – which, of course, we’ve covered already, but both the ones from the disease itself and then ones related to treatment, and what can be done about these? 

Dr. Bhat:

So, disease-related side effects, or we call them disease-related symptoms, include fatigue as a common symptom. Unintentional weight loss can happen. Fevers, chills, or drenching night sweats can happen. We call them, “B symptoms.” Spleen can enlarge, and the enlargement can cause belly pain or feeling of fullness quickly after a meal since spleen is close to our stomach, and as it enlarges, it limits the space stomach can take up in the belly. Lymph nodes can enlarge and can get uncomfortable. So, if any of these symptoms happen, then we have to treat the CLL, and once we start treating the CLL these symptoms should go away. 

As far as treatment-related side effects are concerned, for example, BTK inhibitors are associated with a certain set of side effects. For example, patients can have muscle cramping, muscle pain, joint pain. Patients can have diarrhea. Some of the side effects that we worry about is change in heart rhythm, for example, atrial fibrillation. We talked about that, or increased risk of bleeding.  

Those are some of the side effects we worry about, and if those were to develop, then, of course – for example, a patient has atrial fibrillation, and if it’s symptomatic, we hold the medication. We take care of the atrial fibrillation, usually in collaboration with cardiologists, and once that’s under control, then we have to decide what to do with the treatment. If the atrial fibrillation is under control, we can re-initiate the treatment, or we can go to one of the next-generation BTK inhibitors – the acalabrutinib, the pirtobrutinib, which have less of those side effects. 

Bleeding tends to be a concern, but anything that reduces the risk of bleeding like other medications, aspirin, clopidogrel (Plavix), other blood thinners, we can avoid them, monitor these patients very closely for any of these side effects, so that’s critical. With venetoclax, it’s usually very well-controlled. It’s the initial part of treatment that tends to be a little bit intensive because of the specific side effect called, “tumor lysis syndrome,” which means that the drug works very quickly, and cells die off quickly, they can release stuff in the blood, and things can collect in the blood. 

Uric acid can go up, electrolytes can be up, any number can go up. So, we are aware of this side effect, and we actually pre-emptively have things in place that can prevent this from happening, or if it happens, we manage it right away. For example, venetoclax has a specific dose initiation. For example, it’s called, “dose ramp-up.” We start it at a lower dose, 20 milligrams, for one week. Escalate it to 50 the next week, 100 the third week, 200 fourth week, and 400 the last week, which is the standard dose. They continue on 400 from there onward. 

And even with the slow dose escalation, in the early couple of weeks, we monitor them very closely. Once we initiate a dose, we bring them back to the clinic to recheck their blood work to see if there are any changes. If any changes have happened, we hydrate them, initiate medication for their tumor lysis syndrome. 

If the risk of tumor lysis is very high, then we monitor then admit them to the hospital. Otherwise, long-term side effects of venetoclax, what we have noticed mostly is gastritis, most side effects – mostly diarrhea. But that’s usually well-controlled. We can manage it well with supportive care. 

Katherine:

Here’s another question from Anna. She asks, “What is MRD, and does that mean that the disease is cured?” 

Dr. Bhat:

So, MRD is minimal residual disease, and in CLL is defined as the number of leukemic cells that can be detected in the blood or bone marrow following treatment, meaning how many cancer cells are remaining after treatment? This can be checked by a couple of tests. Most commonly, we use flow cytometry. Undetectable MRD is currently defined as the presence of less than one cell – one CLL cell in 10,000 white cells. 

It’s emerging as an endpoint in a number of clinical trials, and presence of no MRD, also called, “MRD-negative status,” although not considered a cure, predicts better outcomes with longer remission. This is being done in combination treatment, and although it’s part of clinical trials currently, with more data available, we may start using this in clinical practice in the next coming years. 

Katherine:

Sophia wants to know, “Are there any clinical trials regarding Richter’s, or DLBCL, transformation?” 

Dr. Bhat:

So, Richter’s transformation means when CLL, which is a low-grade disease, changes into high-grade lymphoma, and most commonly it’s “diffuse large B-cell lymphoma,” or DLBCL. Currently available treatments for Richter’s transformation are, unfortunately, sub-optimal. So, clinical trials to find better treatments are critical for this division, and there are a number of these currently going on. For example, some trials add targeted agents to the backbone of standard chemotherapy called, “R-CHOP.” 

So, we have one trial where acalabrutinib is being added. There’s another clinical trail where venetoclax is being combined with R-CHOP. One of the problems with Richter’s Transformation is that it tends to be refractory to treatment, and it tends to come back or relapse. So, there are studies ongoing for relapse treatment as well, with combination of targeted agents. And CAR-T therapy, we just talked about that, is also being studied in Richter’s Transformation. So, there’s a lot going on to improve the outcome for this. 

Katherine:

Okay, that’s great. Here’s one from Phil, “How do mutations affect longevity when surviving CLL? What new treatments help with P53 mutation?” 

Dr. Bhat:

So, there are certain prognostic markers for CLL, meaning certain tests that can tell us how a particular patient is expected to do. Some of these tests detect presence or absence of mutations in certain genes. For example, the IGHV gene can be mutated or unmutated. 

In patients with mutated IGHV, they do well, and patients with unmutated IGHV tend to have a more aggressive disease and may require treatment sooner. Similarly, TP53 mutations also tend to require treatment sooner, and more of these mutations do not respond well to conventional chemotherapy. However, targeted therapy has changed the outlook for these mutations, and it works very well for both these mutations. 

Katherine:

Finally, our last question. One audience member would like to know more about how CLL affects the immune system, including wound healing, and how does CLL impact this? 

Dr. Bhat:

So, patients with CLL usually have a weaker immune system. The lymphocyte, which is the white cell, which is affected in CLL, is an important part for an immune system, and due to the presence of disease, these lymphocytes – although there are lots of them in patients with CLL, they tend to be non-functional. 

“Functionally incompetent,” that’s what they’re called. And it leaves the patient’s immune deficient and susceptible to a variety of infections. Also, the lymphocyte is component – the B lymphocyte is one component of immune system. There are other components like T lymphocyte, antibody, MK cell. There’s cross-dock between the B cells and what we call, the “microenvironment,” which is made of the T cells. This cross-dock is deficient in patients with CLL, again making them immune-deficient and susceptible to infection. So, that’s one impact on their immune system. 

Sometimes, there’s something else happening in the immune system where the immune system can go crazy, or wacky, and start attacking the patient’s own blood cells leading to, for example, decrease of hemoglobin or platelets, because these are immune complications. And also, due to a weak immune system, patients with CLL can have delayed wound healing, which also predisposes them to infection. 

So, being aware of these complications is important and using appropriate precautions can be very helpful. Again, because they have a weakened immune system, vaccines are very important. Using all measures to avoid infection, hand washing, staying away from patients, from people who are obviously sick, is very important. Sometimes, patients where we see they’re’ getting frequent infections, we can use what’s called, “IVIG,” intravenous immunoglobulin. These are pre-farmed antibodies which are injected into or infused into the patient at regular intervals before the sixth week, which reduce the chance of these infections. 

Katherine:

Thank you, Dr. Bhat, for all the information. And please continue to send in your questions to question@powerfulpatients.org, and we’ll work to get them answered on future programs. Dr. Bhat, as we close out our conversation, I’d like to get your thoughts on where we stand with CLL progress. Can patients truly thrive with CLL? 

Dr. Bhat:

So, we have made strides in CLL treatment in the past 10 years that really changed the lives of our patients. These treatments work extremely well, and the side effects are gentler than what we used to see with conventional chemotherapy. And it’ll continue to get better with ongoing research, so I will tell our patients to focus on their lives. We know that they have this disease, but we know how to control it well. So, live your life. Enjoy. Be assured that we have all the tools available for you so that you can thrive. 

Katherine:

Yeah. It seems like there’s a lot of hope in the field. Thank you so much for joining us today, Dr. Bhat. It’s been a pleasure. 

Dr. Bhat:

Thank you so much for having me. 

Katherine:

Katherine:

Hello and welcome. I’m Katherine Banwell, your host for today’s program. Today we are going to talk about diffuse large B-cell lymphoma, known as DLBCL and how you can feel empowered to speak up and be a partner in your care. Before we get into the discussion, please remember that this program is not a substitute for seeking medical advice.

Please refer to your health care team about what might be best for you. Well, joining us today is Dr. Kami Maddocks. Dr. Maddocks, welcome. Would you please introduce yourself?

Dr. Maddocks:

Thank you. I’m Kami Maddocks. I’m a lymphoma doctor at the Ohio State University James Comprehensive Cancer Program.

Katherine:

Excellent. Thank you so much for being with us today.

Dr. Maddocks:

Thank you for having me.

Katherine:

Well, since the goal of this webinar is to help our viewers feel empowered in their care, in your opinion, what does it mean to be an empowered patient?

Dr. Maddocks:

I think an empowered patient is invested in their health and in their medical care. This can look like different things for different patients but I think being educated about their disease, being invested in decision making, along with their providers, and then being invested in the outcomes of their treatment and their disease.

Katherine:

What do you feel is the patient’s role in their care?

Dr. Maddocks:

I think it’s important that the patient partners with their care providers and their family, while they’re going through treatment for any condition. So, I think the most important thing is that the patient is comfortable with their care. And I think that includes being educated on their disease process. For some patients, this is going to be doing some of their own research, for some patients, this is going to be really relying and trusting in what their physician and care provider say, and for some patients, this is going to include other information that they seek out after they get the information from their care provider.

Katherine:

How do you empower patients?

Dr. Maddocks:

When I first meet a patient, I schedule a large block of time to spend with the patient, and I like to explain to the patient their new diagnosis. Or, if it’s not a new diagnosis, what I know about their disease, try to understand if they understand what I’m explaining, and what they know before coming to see me.

If there are treatment options, discuss those and go over those and make sure that I ask them to repeat or go over what they understand, from what I’ve explained from that. And then, making sure that they’re comfortable with available options outside of that. So, are there clinical trials available? Should they be seeking second opinions? Where is it best for them to get those second opinions? And then, ensuring that we have open lines of communications, so they have ways to contact me or my office. Making sure that they’re comfortable following up with questions that come in throughout the disease treatment and process. Ensuring that they know to contact us if there are changes or concerns so that we can address things in real time.

Katherine:

Yeah. That’s great advice, Dr. Maddocks. Thank you. Now, let’s learn more about DLBCL. For those who may be newly diagnosed, what is it?

Dr. Maddocks:

Diffuse large B-cell lymphoma is a type of non-Hodgkin’s lymphoma. So, this is considered a blood cancer. Lymphomas are a cancer of the lymphocyte, which is one of the types of blood cells that form your immune system. So, when you think about your nodes, these are part of the cells that help fight different types of infection. So, diffuse large B-cell lymphoma is one of the types of non-Hodgkin’s lymphomas, it’s aggressive, and it is considered an aggressive form of lymphoma. And it’s when you get a cancer of those lymph cells that often involved the lymph nodes but could also involve bone marrow, blood cells, other sites outside of the lymph nodes.

Katherine:

Do we know what causes DLBCL?

Dr. Maddocks:

For the most part, we don’t know what causes diffuse large B-cell lymphoma. So, most of the time, it’s going to arise with patients not having risk factors. We know that age is the most common risk factor with the median diagnosis of a patient in their 60s.

Although, we also know that diffuse large B-cell lymphoma, why it’s more common to be diagnosed later in life, can occur across all the age spectrum. So, you see this in pediatric adolescents, young adults, and older adults. There are some causes. These represent more than minority of cases but certain viruses, including HIV virus, can be associated with the development of lymphoma. Certain other medical conditions, like rheumatologic conditions and some of the treatments for these, can be associated, and then, some chemical exposures. But in general, most of the time, we’re not going to have an identified cause.

Katherine:

What are the symptoms?

Dr. Maddocks:

They can look a little bit different for different patients. So, because this is often a cancer, most of the time there will be lymph node involvement. For some patients, they can actually feel or somebody will see a lymph node that grows. Most of the time, when this occurs, it’s going to be in the neck, under the armpits, or in the groin area.

Patients can start to have symptoms from other sites, of those lymph nodes growing or disease so that they can get pain or shortness of breath. Or they can have what’s called B symptoms. So, B symptoms are inflammatory like symptoms from the lymphoma, and these include weight loss. So, a rapid change in weight for no reason. Night sweats. So, daily night sweats, we call them drenching night sweats. They wake up the patient, they soak their clothes, sometimes they soak the whole bed. And then, fatigue. So, extreme fatigue, not able to do your daily activities. And then, occasional people will have cyclical fevers.

Katherine:

Are there different types of DLBCL?

Dr. Maddocks:

So, in general, diffuse large B-cell lymphoma, there’s one major subtype. You can divide it into different pathological or molecular subtypes.

So, where the cell develops lymphoma during the cell’s development, there are different chromosome abnormalities. So, there are different categorizations but in general, diffuse large B-cell lymphoma itself is considered – it’s treated, often, the same even with these different subtypes. So, there are different subtypes but in general, they’re all considered a form of diffuse large B-cell lymphoma.

Katherine:

They’re under this umbrella of DLBCL.

Dr. Maddocks:

Yeah. Yeah.

Katherine:

Yeah. Do patients usually get diagnosed after they experience some symptoms?

Dr. Maddocks:

So, because this is an aggressive lymphoma, there are a lot of patients that will have symptoms with this, and that’s how they’ll present. Via either noticing the lymph nodes, having the B symptoms, or having pain, or other abnormalities from the lymphoma progressing.

Occasionally, whereas indolent lymphoma is more commonly found of incidentally. Occasionally, that’ll be the case with these, but I would say a fair number of patients have some sort of symptom or something that brings them to medical attention.

Katherine:

How does DLBCL progress?

Dr. Maddocks:

So, they’re different, as far as there’s more aggressive and less aggressive. So, some patients can develop symptoms, really, over days to weeks. Whereas, some patients are more weeks to months.

Katherine:

“Okay. Let’s turn to treatment options. Is a person with DLBCL treated right away?”

Dr. Maddocks:

They’re treated pretty quickly after the diagnosis. So, typically, when somebody has a diagnosis, they undergo a number of different tests, including lab work, imaging work, sometimes for their biopsies.

So, that information is gathered over days to sometimes a few weeks process. Then, when you have all that information, you go over the results, go over the treatment at that time. So, it’s typically treated not within, usually, a day of diagnosis but it’s not something that you spend weeks or months before treating.

Katherine:

Yeah. What are the different types of treatments available?

Dr. Maddocks:

So, the diffuse large B-cell lymphoma is treated with chemotherapy and immunotherapy. So, a combination of an immune antibody therapy and chemotherapy. There is a role in some cases for radiation, but never just radiation alone and never just surgery alone. So, there’s always what we call a systemic treatment. So, a treatment that goes everywhere. Because this is considered a blood cancer, it’s a cancer of those cells, it can really spread anywhere.

And so, just cutting it out with surgery or just radiating the area doesn’t treat everything, even if you can’t identify it.

Katherine:

Can you get specific about some of the treatment classes?

Dr. Maddocks:

Yeah. So, the most common treatment for diffuse large B-cell lymphoma is a chemo immunotherapy called R-CHOP. So, this is three chemotherapies and antibody therapy that’s direct called rituximab (Rituxan) that’s directed at a protein on the lymphoma cells. And then, a steroid called prednisone, given with the chemo and then for a few days after. There was a study that recently showed an improvement with switching one of those drugs with another immunotherapy that’s an antibody conjugated to a chemo drug. But that’s not yet been approved. There are clinical trials available. So, looking at these treatments that might be new or combining therapies with this standard treatment.

And then, very occasionally, there are certain features of diffuse large B-cell lymphoma. There are particular few different subtypes that are classified a little bit differently, that are treated within an infusional therapy called Dose Adjusted R-EPOCH.

Katherine:

What about stem cell therapy? Is that used?

Dr. Maddocks:

Stem cell therapy is used in the relapse setting. So, if a patient doesn’t go into a remission or if they relapse after achieving a remission with their chemotherapy, then stem cell transplant is an option. So, there are actually two different types of stem cell transplant. One from yourself and one from somebody else. In lymphoma, we typically do one from yourself, where you donate your own cell before. But we don’t use that as part of the initial treatment.

Katherine:

So, if somebody is high risk, Dr. Maddocks, is the approach different for them?

Dr. Maddocks:

So, it depends. We define high risk in different ways. So, there’s a specific type of lymphoma called double hit lymphoma, where there’s a few chromosomal translocations associated with the lymphoma, that we give a little more aggressive chemo immunotherapy regimen. There are also other subtypes, including a rare type of lymphoma called primary mediastinal B-cell lymphoma. Again, categorized a little bit different but sometimes included as a large cell lymphoma. We also give that treatment for.

Katherine:

Is a cure possible?

Dr. Maddocks:

Yes. A cure is possible. When you look at patients who are treated with initial chemotherapy, we cure somewhere between 60 percent to 70 percent of patients with the initial chemotherapy. If patients’ relapse, depending on their age and their condition, they’re candidates for other therapies.

And therapy including other chemo and stem cell transplant is potentially curable in some patients. And then, there’s a newer therapy called chimeric antigen receptor T-cell, or CAR T-cell therapy, which also looks like it’s curing a subset of patients who relapse or don’t respond to initial therapy.

Katherine:

Okay. What are the side effects that patients can expect with these treatments?

Dr. Maddocks:

So, when they get the treatment, on the day they get it, there can be an infusion reaction to the rituximab or antibody therapies. So, the first treatment, that treatment is given very slowly and titrated up. If patients have a reaction, we stop it, treat the reaction, and then they’re able to continue therapy but again, that first day, it can take several hours for that one antibody to get in. And then, later, therapies are given at a more rapid pace.

So, about 70 percent of people who react, it can be really almost anything. Some people get flushing, some people will get a fever, some people have shortness of breath or their heart rate will go up.

Katherine:

Okay. All right. Any other side effects?

Dr. Maddocks:

Yeah. So then chemotherapy is meant to kill cells during the cell cycle. So, cancer cells divide more rapidly, chemotherapy is targeting them, but it also effects good cells in the body, specifically those that divide at a more rapid pace. The biggest risk of chemotherapy is infection.

So, it effects the good white blood cells that fight infections. It can affect your red cells that carry your iron, gives you your energy. Or your platelets which help you to clot or not bleed when you get caught. So, infection is the biggest risk of chemotherapy. So, usually, with this regimen, that infectious risk is highest within the second week of treatment, that treatment is given every three weeks.

So, we tell patients they should buy a thermometer, check their temperature, they have to notify their doctor or go to the ER if they have a fever. Besides infection, there’s a small percentage of patients who might need a transfusion. GI toxicity. So, nausea, vomiting, diarrhea, mouth sores, constipation, all of which we have good treatments for. So, we give medication before chemo to try to prevent people from getting sick and then give them medicine to go home with, if they have any nausea. We can alter those medications as time goes on, if they’re having any problems. So, we just need to know about it. Most patients will lose their hair with this regimen.

It can affect people’s tastes, it can make their skin more sensitive to the sun, and then, less common but potential side effects are it can cause damage to the nerves. Or something we call neuropathy, which most often patients will start with getting numbness or tingling in their fingers and toes, and we can dose adjust if that’s causing some problems.

And then, there’s a risk to the heart with one of the drugs. So, the heart should pump like this. The heart pump function can go down. So, we always check a patient’s heart pump function before they get their chemo, to make sure that they’re not at higher risk for that to happen.

Katherine:

So, all of these approaches are used in initial treatment?

Dr. Maddocks:

Mm-hmm.

Katherine:

Okay. So, how do you know if a treatment is working?

Dr. Maddocks:

So, as far as evaluating treatment, you get a scan before you start treatments, so we know where all the lymphoma is at. And then, typically, you get some sort of scan in the middle of treatment, and then after, you complete your six cycles of treatment. Or for early stages, sometimes patients will get less than six cycles. So, we get scans to make sure it’s working. So, you can tell by those things, how much has gone, hopefully all of it has gone by the end. Occasionally, patients that had a lot of symptoms to start with, their symptoms will go away, and then they’ll start coming back.

This is less common, because the majority of patients do respond to chemotherapy. It’s less common to get patients who are what is called refractory, meaning they don’t get any response to therapy. So, occasionally they’ll note symptoms but a lot of times, we’ll see something on that mid-therapy or end of therapy scan, if it’s not going to make it all go away.

Katherine:

Yeah. So, if a treatment doesn’t work, what happens then?

Dr. Maddocks:

If treatment doesn’t work, it depends a little bit – and now it depends a little bit on the timing of that treatment not working. So, it used to be that patients who were eligible for treatment, no matter if it didn’t work right away or if it put them into what we call a remission, so there’s no evidence of disease and then it relapsed, they would have the option of further chemotherapy and then an autologous stem cell transplant. So, a bone marrow transplant where they donate their own cells.

If they were in a good enough health or if they were not – to do that, you have to donate your own bone marrow cells and as we age, we make less bone marrow cells. So, once you reach a certain age, your body can’t produce enough cells to donate to a transplant. In those patients, we offer them less aggressive chemo options, which were not known to be curable but could put them into remission again, for a while. More recently, there has been some that chimeric antigen receptor T-cell therapy that I mentioned where you actually donate your own T cells. So that’s –And your lymphoma is of your B cells.

Your T cells are in another immune cell that should recognize that lymphoma is bad and attack it, and they’re not functioning properly. So, you donate your own T cells and they’re sent off and reengineered to target a protein on the tumor. Then, you get those cells back and they’re meant to target the lymphoma and kill the lymphoma cells.

So, that is now an approved therapy for patients who don’t achieve the remission – so, who’s first chemo doesn’t work or if they relapse within a year of completing chemo. So, that’s a possibility. The chemo and transplants a possibility. Or there’s other approved therapies now, that can be given as second options or third or later options, which have been shown to keep patients in remission for a while.

Katherine:

Dr. Maddocks, you touched up on this a moment ago but what are the approaches if a patient relapses? What do you do?

Dr. Maddocks:

So, you would rework them up if they relapsed. Similar to that, if they relapse within a year and they have access to the CAR-T and they’re healthy for that, then that’ll be an option. The second type of chemotherapy in the transplant. So, you can’t just go straight to a transplant. You have to get a different type of chemotherapy to try to get the disease under control again, before you would go to a transplant.

Or there’s a number of other targeted therapies that are approved. So, there’s other – I talked about rituximab is given in the first line, that targets a CD-20 protein, there’s an antibody that targets a CD-19 protein that’s given out in relapse. There’s another antibody drug – there’s actually two antibody drug conjugates. So, an antibody that targets the protein on the cells that are attached to a chemo, that’s given. Or there’s different chemotherapy and then even some oral therapies.

Katherine:

Okay. So, there’s a lot of different options available for people.

Dr. Maddocks:

Correct. And there’s always clinical trials. So, there’s always the option to find something where we’re studying some of these newer therapies. They’re therapies in combination.

Katherine:

Well, that leads us right into emerging options and I’d like to talk about that. Have there been any recent developments in how DLBCL is treated?

Dr. Maddocks:

There had been recent developments. So, the CAR T-cell therapy, there is now three approved options for patients. And so, even patients who maybe are older and not considered candidates for a stem cell transplant because of other medical factors, might be able to get the CAR T-cell therapy. This is now, again, approved in the second line. There are a couple antibody drug conjugates, polatuzumab (Polivy) and loncastuximab (Lonca, Zylonta), they target proteins called CD-79 and CD-19.

And the polatuzumab’s the one that probably is going to be available for part of the front-line treatment in the future. There’s the antibody tafasitamab (Monjuvi) and lenalidomide (Revlimid). These are all approved therapies in the relapse setting. There are also therapies that are being studied and showing promising activity, which we think are probably likely to be approved in the future. There’s something particularly called bi-specific antibodies.

So, this targets a protein on the tumor cell but also a protein on the T cell. So, remember I said the T cells aren’t functioning. So, this targets the protein on the lymphoma cell but then targets a protein on the T cell to engage it to attack the lymphoma cell.

Katherine:

Right. Combination approaches?

Dr. Maddocks:

Yeah. So, there are a number of combination approaches under study a lot of the therapies that I mentioned, like the bi-specific antibodies, the antibody drug conjugates. These are all therapies that – they have side effects – I hate to say they’re well-tolerated – they have side effects but their side effects are such that they can be combined with other agents, that have different toxicities that are combined with each other. And so, there’s a lot of ongoing trials looking at combining these. There’re also oral targeted therapies that target proteins that are known to help the lymphoma cells survive and these are modulator therapies, BTK inhibitors, other inhibitors, that are being evaluated and used in combinations.

Katherine:

Thanks, Dr. Maddocks. That’s really helpful information. So, now that we understand more about DLBCL and how it’s treated, let’s talk about self-advocacy and how patients can engage in their own care. Why is it so important for patients to have a voice in their decisions?

Dr. Maddocks:

Well, I always tell my patients that they are the person most invested in their selves and their outcomes. As a care team, we certainly are invested in them and we want them to do well but they’re the one that knows their body, they know what’s going on, they’re the one that has to, essentially, live with all these outcomes. So, they have to be invested in what’s going on, they have to be invested in making sure that they know their care team is informed of things because we only see them in different periods of time and we’re not with them all the time to know what’s going on.

Katherine:

Right. It’s not always easy for patients to speak up. So, I’d like to debunk some common misconceptions that patients have, that may be holding them back. First one is, “I’m bothering my doctor with all my questions.” Is that true?

Dr. Maddocks:

That is not true at all. So, the best thing is an informed patient. So, I want to answer all their questions. “What is the disease or diagnosis?” “What are the treatment options?” “What do we know now?” “What are we learning?” I need to know what’s going on. I always tell my patients that I can’t help them with what I don’t know. So, if somebody shows up, they get once cycle of treatment and they show up for a second cycle and they’ve had all these problems and never called or notified me, first of all, we weren’t able to help them. There’s a lot of things we can do to help them and if we don’t know what’s going on, we can’t help.

And second, that might impact that second treatment, whereas knowing and knowing that sooner, we can plan to make changes.

Katherine:

Yeah. That’s really good advice. Here’s another one. “My doctor’s feelings will get hurt if I get a second opinion.”

Dr. Maddocks:

Not at all. So, I always encourage patients that they should get a second opinion, third opinion, whatever they need. Number one, I think it’s important that a patient feels comfortable with their diagnosis and their treatment

plan because I really think that things go better if they understand that and they’re comfortable. If they’re always doubting what’s going on, it’s really hard to develop that trusting relationship. And I think it’s very important that a patient has a trusting relationship with their care team.

I think most of the time, when you get a second opinion, you’re probably going to hear or get the same advice. And so, that helps a patient to feel comfortable. Sometimes, there may be clinical trials out there that your doctor didn’t know about, that are options, and a doctor’s always going to be happy if there’s something out there available, that might make the patient outcome better, that they didn’t know about.

And lastly, I would say there are a lot of doctors who treat all types of cancer and there are some doctors that specialize in certain types of cancer. And so, if you were seeing a doctor who treats multiple different kinds, but want to see a doctor who specializes in a particular kind, they may be aware of a recent trial or a recent development that your doctor doesn’t know. Not because there’s anything wrong with that doctor, it’s just that there is so much data to keep up with these days, in cancer, that a specialist might be able to provide a point of view that somebody else doesn’t know.

Katherine:

Yeah. Another question or comment is, “There isn’t anything that could be done about my symptoms or treatment side effects. So, why should I even say anything?”

Dr. Maddocks:

That’s a great question but the thing is, a lot of times there are things. So, the one thing is, some of the treatments we use for some of our cancers, including lymphoma, have been around for a really long time. But some of the things that have changed, are our supportive care or our ability to treat patient side effects. So, I think that it’s always important that patients let us know if they’re having side effects because maybe nausea – so, we give medication to prevent that.

Usually, I send patients home with two different types of nausea medication. But if that’s not helping, I have more than two in my toolbox, I just don’t know to prescribe them if the typical things aren’t helping. So, a lot of times, there are things that we can do. Sometimes you have to tweak the dosing of the chemo, but really, the only way you can help with symptom management is if you know somebody’s having symptoms.

Katherine:

Right. So, when somebody starts to have side effects from the treatment, should they contact their care team right away?

Dr. Maddocks:

Yes. They should contact their care team right away. There are certain side effects, like having a fever during chemo, where they really need to go to the emergency room to be evaluated, to make sure it’s nothing. Because an infection can be very serious when you’re getting chemotherapy. Other side effects that are less emergent but, yes. Most of the time there’s a patient number that patients can call, where they can seek, like a nurse help line, where they can seek assistance, and that call can be escalated depending on the symptoms and what needs to be helped.

But I think, again, it’s important that we know what’s going on so we can help patients. And then, if something needs to be further investigated – because occasionally there will be something that’ll make us think, “Oh, we really need to evaluate this patient because what if it’s more than what it seems?”

Katherine:

Right. Are there any other misconceptions that you hear about from patients?

Dr. Maddocks:

I think, just in general, thinking about the patient taking care of themselves. So, a lot of times there can be resources that patients have questions on. Things like exercise. Things like nutrition. Things in the environment that they can be exposed to. Just different things. I think it’s always important that you ask your care team if there’s any question because they’re going to best be able to tell you versus just assuming something.

There’s a lot of good information that patients can get from educational sites. There’s a lot of good information on the internet but there’s also a lot of bad information, or inaccurate information on the internet. So, I think it’s great for patients to use resources and educate themselves but I think that it’s always good to confirm with your care team. Myths versus facts.

Katherine:

Yeah. Yeah. That’s really important. Do you recommend that patients continue getting vaccines? For COVID, for flu?

Dr. Maddocks:

Yes. So, particularly, when you look at lymphomas, this is a cancer of the immune system. The cancer can make your immune system compromise the treatment. While you’re getting treated makes your immune system compromised. And even for a period after treatment, your immune system can be compromised. So, it’s important to protect yourselves against infection. Sometimes the efficacy of vaccines in the middle of treatment might not be as good as not being on treatment.

But that said, there’s no data that the vaccines are harmful. You do have to be careful about live vaccines when you’re under treatment, and you should ask your doctor about not the typical vaccines, of course. But I think that it’s very important to take every step that patients can, to try to prevent themselves from battling something in addition to them already undergoing treatments, their body’s already going through a lot.

And so, anything that we can do or they can do to help prevent them from dealing with more than they already are, I think is important.

Katherine:

To close, what would you like to leave the audience with? Do you think that people can feel hopeful about the tools available to treat DLBCL?

Dr. Maddocks:

Yeah. I think, if you look at the progress we’ve made in the last five years, the last drug approved was rituximab in the early 2000s, and now in the last five years, we have had numerous therapies approved. Now it looks like we’re changing front-line therapy and numerous therapies that relapse. So, there’s a lot of – these are all promising therapies, some of them potentially curing patients that we weren’t able to cure before.

And so, they’re more available to patients. There’s a lot of promising drugs in clinical trials. And so, I think it’s hard to deal with a diagnosis but there are options for patients, both initially and at relapse, and I think seeking out what’s available, both to you and in clinical trials, is important to helping further improve outcomes.

CLL Treatment Approaches: What Are the Types?

What is YOUR Role in Choosing a CLL Treatment Approach?

Transcript:

Katherine Banwell:

What are the common side effects of treatments, and how are they managed? 

Dr. Jean Koff:

So, each of the different classes of agents has a different profile of side effects. The BTK inhibitors, the first class that I mentioned with ibrutinib (Imbruvica) and acalabrutinib (Calquence), are usually very well tolerated. The most common side effects that we tend to see are things that the patients can feel or see, but also things that we can see on the labs when we’re monitoring patients. So, sometimes you can see a lower platelet counts or lower blood cell counts with ibrutinib. That’s something that you may not notice, but your doctor’s going to notice on the – the blood counts when you come to the office. Sometimes ibrutinib can cause a rash or GI upset, this is usually easily managed with supportive care from your physician.  

And then some more – some more common effects of the BTK inhibitors include joint pain and headache. And again, many physicians, because we’ve been using BTK inhibitors for a long time, have a good regimen for treating these side effects. More uncommon side effects of BTK inhibitors, particularly ibrutinib that we look out for would be abnormal heart rhythms and some tendency for bleeding. But these are relatively uncommon and with newer BTK inhibitors, we’re seeing lower rates of these side effects.  

Dr. Jean Koff:

So, in terms of venetoclax side effects we have a little bit of a different profile. This agent is much more likely to cause lower cell counts, especially in a white blood cell count known as neutrophil count, and so your doctor will be monitoring you for that. In terms of patient side effects that you can feel, it can cause a rash, it can cause some GI upset. These are usually relatively easily managed but we want you as the patient if you’re on venetoclax to talk to your doctor about these side effects so that they can help you feel better and help you manage those. In terms of the anti-CV20 monoclonal antibodies, which we use a couple in CLL more frequently, they have very similar side effect profiles.  

So, one is rituximab, and one is obinutuzumab. Obinutuzumab is usually used in combination with venetoclax in front-line CLL.  

Like I mentioned before, this is an infusion and most of the side effects that we think about and most commonly see in these anti-CV20s are side effects that patients have during the infusion. And these are referred to as infusion reaction. And these are relatively common, around 30 percent in these anti-CV20 monoclonal antibodies. So, what is an infusion center react – er sorry, what does an infusion reaction look like? This looks sort of like an allergic reaction. 

Katherine Banwell:

Hm. 

Dr. Jean Koff:

So, your nurses in the infusion center are going to be monitoring you very carefully once you start the infusion, and they’re going to start it at a low dose, very slowly. But the side effects they’re monitoring for, they’re looking for changes in your heart rate or blood pressure. You may start to feel hot or cold or sweaty, you may have chills. Sometimes patients can have swelling in their throat or their tongue. And what will happen is because these are fairly common, is we’re still able to give the anti-CV20, but what we do is the nurse will stop the infusion, they may give you some medications that calm down that infusion reaction. So, medications like antihistamines –  

Katherine Banwell:

Mm-hmm.  

Dr. Jean Koff:

Or steroids that help tamp down that immune response, and then they start the anti-CV20 infusion at a lower rate. The vast majority of patients will be able to receive an anti-CV20 antibody even if they have an infusion reaction. They may just need a little bit more of those immune tamping-down medications like antihistamines and steroids. And then the last thing to consider, which I think we’ve mentioned, especially in the venetoclax-containing regimens, is the tumor lysis syndrome. And so, that is a side effect like we mentioned is kind of like the venetoclax working really, really, really well, of the tumor breaking down too quickly.  

And so, patients who have tumor lysis, if they’re at high-risk, hopefully they’re already being monitored very closely with frequent lab draws, and they may receive medications that – that diminish the risk of adverse events happening because your electrolytes are out balance, for instance, your potassium is too high, or your calcium is too low. Because your doctors are monitoring you closely, they can give you medications that can help balance  out those – those electrolytes and help protect the kidneys. The tumor lysis is typically not a risk after the initial doses of venetoclax.  

So, the first couple weeks is when we typically monitor that, and then once the CLL has been broken down, or as I like to say, once it’s been cooled off a little bit, then you no longer have this risk of tumor lysis and it – it doesn’t require further monitoring. 

Katherine Banwell:

That’s great information, thank you.

CLL Treatment Approaches: What Are the Types?

Transcript:

Katherine Banwell:

Many patients are overwhelmed by the different types and classes of treatment. When is it time to treat CLL, and what are the options? 

Dr. Jean Koff:

So, I boil down the criteria to when you need to treat your CLL to two main categories. One category is that the disease is progressing quickly, and the other category is the disease is causing problems of some kind, or getting ready to cause problems of some kind. Those are some of the broad categories that we think about when it’s time to start treatment for CLL. Now, this – the groups that research CLL have put out various criteria that help guide physicians about when it’s time to start treatment, and some of those more specific criteria include items like symptoms. So, symptoms are a very important part of that decision-making process.   

And the same symptoms that we mentioned, the B symptoms, fevers, chills, night sweats, weight loss that’s unintentional, or lymph nodes that you can feel, those would potentially be reasons that your doctor would want to start you on CLL therapy. But the CLL can cause issues even in a patient who’s not necessarily having symptoms. So, one of the most common ways that CLL can cause issues is the CLL cells can cause your other blood cells, the normal blood cells, to be low in number. There are several ways the CLL cells can do this. One of the most common ways is that the CLL cells, which are often circulating through your bloodstream, can also collect or overrun your bone marrow.  

And if you think about it, the bone marrow is the factory that makes all of your blood cells. So, when there are too many CLL cells in the bone marrow, they can crowd out the normal blood cells, like red blood cells or platelets. So, when red blood cells or platelets get low beneath certain thresholds, that’s a reason to start CLL therapy. 

Katherine Banwell:

Mm-hmm.   

Dr. Jean Koff:

So, there are a couple other criteria that we think about. CLL cells can collect in other areas, including the spleen. So – and if you remember, the spleen is a lymphoid organ that sits on the left side of your body that is right below the stomach. And so, if CLL cells collect in the spleen, they can cause it to be too big, it can press on the stomach, it can make it so you feel full, even if you haven’t eaten a full meal, that’s something we call early satiety. It can be uncomfortable, causing some abdominal pain. And if the spleen gets really, really big, it can cause it to not be able to do its normal job, which is to filter out the normal blood cells like it does every day. And so, that would be a reason to start therapy as well. And then the last – the last category I would think about is in CLL we have lots of – of CLL cells that are circulating in the blood that we can check with a routine blood count. And the absolute number of CLL cells is not as important as how fast that number is growing. So, your physician will track how fast that number of CLL cells is doubling.  

And if you meet criteria for what we call rapid doubling time, which is usually thought of as less than 12 months but certainly less than six months. So, if your count goes from 30,000 to 60,000 in under six months, then it may be time for you to start thinking about therapy. 

Katherine Banwell:

Right. So, Dr. Koff, would you briefly review the treatment classes? 

Dr. Jean Koff:

So, for first-line treatment, we have two main treatment classes that we think about at this time. The first is – is called BTK inhibitors, which is Bruton tyrosine kinase inhibitors. And these are oral medications, so medications that you take by mouth, and the most well-studied of these is called ibrutinib (Imbruvica), we typically prescribe ibrutinib by itself. There are other BTK inhibitors we are also now using in this space, one of them is called acalabrutinib  (Calquence), and that is often given with an IV monoclonal antibody called obinutuzumab (Gazyva).   

The other main class of drugs that we consider for first-line treatment of CLL is the BCL-2 inhibitors. Right now there’s only one BCL-2 inhibitor that’s approved for CLL and front-line and it’s called venetoclax (Venclexta). Usually, this drug is also given in the front-line with an anti-CD20 monoclonal antibody. So, the venetoclax itself is a pill you take. And the monoclonal antibody is an – either an IV or a subcutaneous injection.  

Katherine Banwell:

Where do clinical trials fit into CLL treatment? 

Dr. Jean Koff:

So, clinical trials are part of the reason, a big part of the reason that we’ve been able to make so much progress in how we treat CLL over the past few years. Clinical trials are how we figure out what treatments work for CLL, how patients feel on them, what sort of adverse events or side effects they have on individual treatments, and which treatments do better for keeping CLL symptoms under control, keeping the disease under control, and allowing patients to live longer and have a higher quality of life with their disease.   

Katherine Banwell:

Are there any other options available for CLL patients?  

Dr. Jean Koff:

So, there are other options. A clinical trial, if that is available to you as a patient is nearly always a good thing to consider if you have CLL. Because the vast majority of patients will not be cured by CL – by their treatment for CLL. Meaning that the – even though the treatments we have usually work for a very long time in most patients, ultimately the CLL will at some point, perhaps years down the road, progress and need another therapy. For that reason, we know we can do better. And we are hoping that the next  clinical trial is going to lead to the discovery of a new agent or a new combination – new  combinations of agents that will allow patients to live longer with a better quality of life with CLL.  

Katherine Banwell:

Mm-hmm. 

Dr. Jean Koff:

So, that’s always a good option to consider.

Dr. Jean Koff:

Hi, I’m Jean Koff. I’m a lymphoma and CLL specialist from Emory University and it’s a pleasure to be with you here today. 

Katherine Banwell:

Thank you for taking the time to join us. We start all of our webinar in our CLL Thrive series with the same question. In your experience, what does it mean to thrive with CLL? 

Dr. Jean Koff:

So, I think thriving with CLL means that a patient is informed about their disease, they are comfortable with the physician who’s helping them navigate their disease and their management plan. And their management plan, whatever that might be, is really allowing them to focus on their life outside of CLL. So, keeping their symptoms to the absolute minimum, their physician keeping them informed about their disease progress, or lack thereof, in terms of keeping the disease at bay so they can focus on all of those things that bring them enjoyment outside of the CLL world. 

Katherine Banwell:

That’s great. Thank you for your perspective. One part of thriving  with CLL is managing the symptoms of the disease. What are the common symptoms of CLL? 

Dr. Jean Koff:

So, one thing that I see with nearly all of my CLL patients, regardless of where they are in the CLL journey, and regardless of whether they need active medications to manage their CLL, is some degree of fatigue. And this can range from just mild fatigue that patients notice that they need a little bit of a breather in the middle of the day, to needing more sleep at night, to not being able to exercise as much as they’re used to. And that is by far one of the most common symptoms we see. Again, whether or not their disease needs medication to manage it. The classic symptoms of CLL that often let us know that it’s time to start medical management, are not just this fatigue. But the classic symptoms are B symptoms. And we describe those as fevers, night sweats, and unintentional weight loss. Those are very common. And then some patients with CLL will also have what we call palpable lymphadenopathy, which is our term for lymph nodes that are enlarged that you can feel. And the most common places to feel these on the body are on the neck, under the arms, and in the groin.  

Katherine Banwell:

Okay. How are symptoms treated? 

Dr. Jean Koff:

So, if your symptoms progress to the point that your doctor thinks you need medication – they’re becoming disruptive to your life, or they are getting worse and worse over time, then there are a variety of medications that we can use in CLL. And this is actually a very exciting field. Right now, the state of the field is that most patients who are starting on their first treatment for CLL will use some sort of oral medication, and that may be accompanied by an IV – what we call monoclonal antibody, or it may not. But one thing that has really changed even since I very first started practicing, is that we no longer commonly use what I would call conventional chemotherapy to treat CLL. Even though this was the standard of care just a few years ago. 

Katherine Banwell:

Wow. So, a lot has changed. 

Dr. Jean Koff:

Yes, definitely. 

Katherine Banwell:

Why is it so important for patients with CLL to speak up and communicate with their healthcare team about some of their symptoms? 

Dr. Jean Koff:

Well, for starters we want you to feel better. That’s our number one job as – as physicians, is we want to get you to feeling to – to where you are feeling like your best self. CLL or not. So, we want to make you feel better. But in CLL your symptoms are actually one of the criteria we consider when we’re thinking about whether or not we need to start a new therapy, or if you’re somebody who’s already on therapy, whether we need to change your therapy. So, it’s actually very important and your CLL doctor should be checking in with you regularly to see if you have new or worsening symptoms that might be due to your CLL.  

Katherine Banwell:

Mm-hmm. It sounds like treatment of the disease is key to controlling your symptoms. So, let’s talk about treatment. Many patients are overwhelmed by the different types and classes of treatment. When is it time to treat CLL, and what are the options?  

Dr. Jean Koff:

So, I boil down the criteria to when you need to treat your CLL to two main categories. One category is that the disease is progressing quickly, and the other category is the disease is causing problems of some kind, or getting ready to cause problems of some kind. Those are some of the broad categories that we think about when it’s time to start treatment for CLL. Now, this – the groups that research CLL have put out various criteria that help guide physicians about when it’s time to start treatment and some of those more specific criteria include items like symptoms. So, symptoms are a very important part of that decision-making process.  

And the same symptoms that we mentioned, the B symptoms, fevers, chills, night sweats, weight loss that’s unintentional, or lymph nodes that you can feel, those would potentially be reasons that your doctor would want to start you on CLL therapy. But the CLL can cause issues even in a patient who’s not necessarily having symptoms. So, one of the most common ways that CLL can cause issues is the CLL cells can cause your other blood cells, the normal blood cells, to be low in number. There are several ways the CLL cells can do this. One of the most common ways is that the CLL cells which are often circulating through your bloodstream can also collect or overrun your bone marrow.   

And if you think about it, the bone marrow is the factory that makes all of your blood cells. So, when there are too many CLL cells in the bone marrow, they can crowd out the normal blood cells, like red blood cells or platelets. So, when red blood cells or platelets get low beneath certain thresholds, that’s a reason to start CLL therapy. 

Katherine Banwell:

Mm-hmm.   

Dr. Jean Koff:

So, there are a couple other criteria that we think about. CLL cells can collect in other areas, including the spleen. So – and if you remember, the spleen is a lymphoid organ that sits on the left side of your body that is right below the stomach. And so, if CLL cells collect in the spleen, they can cause it to be too big, it can press on the stomach, it can make it so you feel full, even if you haven’t eaten a full meal, that’s something we call early satiety. It can be uncomfortable, causing some abdominal pain. And if the spleen gets really, really big, it can cause it to not be able to do its normal job, which is to filter out the normal blood cells like it does every day. And so, that would be a reason to start therapy as well. And then the last – the last category I would think about is in CLL we have lots of – of CLL cells that are circulating in the blood that we can check with a routine blood count. And the absolute number of CLL cells is not as important as how fast that number is growing. So, your physician will track how fast that number of CLL cells is doubling.  

And if you meet criteria for what we call rapid doubling time, which is usually thought of as less than 12 months but certainly less than six months. So, if your count goes from 30,000 to 60,000 in under six months, then it may be time for you to start thinking about therapy. 

Katherine Banwell:

Right. So, Dr. Koff, would you briefly review the treatment classes? 

Dr. Jean Koff:

So, for first-line treatment, we have two main treatment classes that we think about at this time. The first is – is called BTK inhibitors which is Bruton tyrosine kinase inhibitors. And these are oral medications, so medications that you take by mouth, and the most well-studied of these is called ibrutinib, we typically prescribe ibrutinib by itself. There are other BTK inhibitors we are also now using in this space, one of them is called acalabrutinib and that is often given with an IV monoclonal antibody called Obinutuzumab.   

The other main class of drugs that we consider for first-line treatment of CLL is the BCL-2 Inhibitors. Right now there’s only one BCL-2 Inhibitor that’s approved for CLL and front-line and it’s called venetoclax. Usually, this drug is also given in the front-line with an anti-CD20 monoclonal antibody. So, the venetoclax itself is a pill you take. And the monoclonal antibody is an – either an IV or a subcutaneous injection.  

Katherine Banwell:

Where do clinical trials fit into CLL treatment? 

Dr. Jean Koff:

So, clinical trials are part of the reason, a big part of the reason that we’ve been able to make so much progress in how we treat CLL over the past few years. Clinical trials are how we figure out what treatments work for CLL, how patients feel on them, what sort of adverse events or side effects they have on individual treatments, and which treatments do better for keeping CLL symptoms under control, keeping the disease under control, and allowing patients to live longer and have a higher quality of life with their disease.  

Katherine Banwell:

Are there any other options available for CLL patients? 

Dr. Jean Koff:

So, there are other options. A clinical trial, if that is available to you as a patient is nearly always a good thing to consider if you have CLL. Because the vast majority of patients will not be cured by CL – by their treatment for CLL. Meaning that the – even though the treatments we have usually work for a very long time in most patients, ultimately the CLL will at some point, perhaps years down the road, progress and need another therapy. For that reason, we know we can do better. And we are hoping that the next clinical trial is going to lead to the discovery of a new agent or a new combinations – new combinations of agents that will allow patients to live longer with a better quality of life with CLL.   

Katherine Banwell:

Mm-hmm. 

Dr. Jean Koff:

So, that’s always a good option to consider. 

Katherine Banwell:

Mm-hmm. What are the common side effects of treatments, and how are they managed? 

Dr. Jean Koff:

So, each of the different classes of agents has a different profile of side effects. The BTK inhibitors, the first class that I mentioned with ibrutinib and acalabrutinib, are usually very well tolerated. The most common side effects that we tend to see are things that the patients can feel or see, but also things that we can see on the labs when we’re monitoring patients. So, sometimes you can see a lower platelet counts or lower cell counts with ibrutinib. That’s something that you may not notice, but your doctor’s going to notice on the – the blood counts when you come to the office. Sometimes ibrutinib can cause a rash or GI upset, this is usually easily managed with supportive care from your physician.  

And then some more – some more common effects of the BTK inhibitors include joint pain and headache. And again, many physicians, because we’ve been using BTK inhibitors for a long time, have a good regimen for treating these side effects. More uncommon side effects of BTK inhibitors, particularly ibrutinib that we look out for would be abnormal heart rhythms and some tendency for bleeding. But these are relatively uncommon and with newer BTK inhibitors, we’re seeing lower rates of these side effects.  

So, in terms of venetoclax side effects we have a little bit of a different profile. This agent is much more likely to cause lower cell counts, especially in a white blood cell count known as neutrophil count, and so your doctor will be monitoring you for that. In terms of patient side effects that you can feel, it can cause a rash, it can cause some GI upset. These are usually relatively easily managed but we want you as the patient if you’re on venetoclax to talk to your doctor about these side effects so that they can help you feel better and help you manage those. In terms of the anti-CV20 monoclonal antibodies, which we use a couple in CLL more frequently, they have very similar side effect profiles.   

So, one is rituximab, and one is obinutuzumab. Obinutuzumab is usually used in combination with venetoclax in front-line CLL.  

Like I mentioned before, this is an infusion and most of the side effects that we think about and most commonly see in these anti-CV20s are side effects that patients have during the infusion. And these are referred to as infusion reaction. And these are relatively common, around 30 percent in these anti-CV20 monoclonal antibodies. So, what is an infusion center react – er sorry, what does an infusion reaction look like? This looks sort of like an allergic reaction.  

Katherine Banwell:

Hm.  

Dr. Jean Koff:

So, your nurses in the infusion center are going to be monitoring you very carefully once you start the infusion, and they’re going to start it at a low dose, very slowly. But the side effects they’re monitoring for, they’re looking for changes in your heart rate or blood pressure. You may start to feel hot or cold or sweaty, you may have chills. Sometimes patients can have swelling in their throat or their tongue. And what will happen is because these are fairly common, is we’re still able to give the anti-CV20, but what we do is the nurse will stop the infusion, they may give you some medications that calm down that infusion reaction. So, medications 

 like antihistamines –  

Katherine Banwell:

Mm-hmm. 

Dr. Jean Koff:

Or steroids that help tamp down that immune response, and then they start the anti-CV20 infusion at a lower rate. The vast majority of patients will be able to receive an anti-CV20 antibody even if they have an infusion reaction. They may just need a little bit more of those immune-tamping down medications like antihistamines and steroids. And then the last thing to consider, which I think we’ve mentioned, especially in the venetoclax-containing regimens, is the Tumor lysis syndrome. And so, that is a side effect like we mentioned is kind of like the venetoclax working really, really, really well, of the tumor breaking down too quickly.  

And so, patients who have Tumor lysis, if they’re at high-risk, hopefully they’re already being monitored very closely with frequent lab draws, and they may receive medications that – that diminish the risk of adverse events happening because your electrolytes are out balance, for instance, your potassium is too high, or your calcium is too low. Because your doctors are monitoring you closely, they can give you medications that can help balance out those – those electrolytes and help protect the kidneys. The Tumor lysis is typically not a risk after the initial doses of venetoclax.  

So, the first couple weeks is when we typically monitor that, and then once the CLL has been broken down, or as I like to say, once it’s been cooled off a little bit, then you no longer have this risk of Tumor lysis and it – it doesn’t require further monitoring.  

Katherine Banwell:

That’s great information, thank you. What is the patient’s role in deciding on a treatment plan? 

Dr. Jean Koff:

So, it’s very important that the patient be involved in deciding on a treatment plan. Especially in first-line. Because we have these two excellent classes of agents, the BTK inhibitors and the venetoclax- containing regimens. Both of them have been shown to have very good what we call efficacy in CLL, meaning that they’re able to control the disease, patient’s symptoms largely at bay for long periods of time. You know, we’re talking an average of years that – that patients are on these therapies. And they each, like I said have different side effect profiles.  

And they’re given in slightly different ways. And so, right now we don’t have data from our clinical trials comparing a BTK inhibitor regimen to a venetoclax-containing regimen in CLL patients to tell us one is better than the other. And so, for that reason, a lot of the decision-making about which therapy is going to be better for you, or which therapy you would prefer, lies with the CLL patient rather than with the doctor. And the things that I ask my patients to consider, there are a couple different things. One is the side effect profile. So, patients may be more or less comfortable with certain side effects of one drug compared to another. Or there may be something in the patient’s medical history that puts them more at risk for a certain side effect than another. 

The other major player in this decision-making process is how these drugs are given. So, with ibrutinib, the ibrutinib is given as a pill that you take once a day, and you take it indefinitely. Meaning you take that pill once a day for as long as it’s doing what it’s supposed to do, which is keeping your CLL under control, and as long as the patient is tolerating it well. Meaning you’re not having a lot of uncomfortable side effects from the ibrutinib. So, I have patients who have been on ibrutinib for years and years and years and years.  

The venetoclax-containing regimen for patients who are getting their first-line treatment in CLL is different. It is designed as a – what we call time-limited therapy. And so, this regimen is given in – over about 12 months, 12 or 13 months, and then stopped. As long as the patient has had a good response. The other thing to consider with the venetoclax regimen, it’s not just the pill. You do take a pill every day, but you also get a – an infusion for about six months of the monoclonal antibody. Meaning that you’ll have to come into the infusion center and get an infu – an IV infusion of this drug called Obinutuzumab. The last consideration with the venetoclax regimen that differs in how it’s administered, is the venetoclax often works so well that it can break down the CLL cells a little bit too quickly.  

And so, for patients who have a very, very high white count, or large lymph nodes due to their CLL, there is a risk of something we call Tumor lysis syndrome, which refers to the process where the tumor cells break down very, very quickly, and they produce molecules that are released into the bloodstream that can be dangerous if they get too high or too low. And so, sometimes, in some patients we have to monitor for the Tumor lysis syndrome by checking labs fairly frequently after we start the venetoclax. And for some patients that means they have to stay overnight for a night or two in the hospital for lab monitoring.  

So, for some of my patients that I talk to about venetoclax, they say I want to stay out of the hospital, I just want to take a pill, I’m fine taking a pill, I’ll go with the BTK inhibitors. For other patients, they say I don’t want to be on a pill every single day, I will go through this year of therapy, I’m comfortable with that, and I’m happy that I’ll be able to take a break from therapy after one year. So, that ends up being a large factor in many of the conversations I have with my patients about which therapeutic approach we’re going to use in front-line therapy. 

Katherine Banwell:

Hm. Dr. Koff, we received a patient question prior to the program. If I’ve had FCR for my first treatment, does that prevent me from having – or having to take an oral drug later on? 

Dr. Jean Koff:

Absolutely not. So, the very first clinical trials that we did studying these regiments, especially the BTK inhibitors, were performed in patients who had received conventional chemotherapy like FCR. And what we saw is that patients who had received conventional chemotherapies and had – and needed retreatment of their CLL responded very, very well to agents like ibrutinib. And ibrutinib was able to control their disease, control their CLL, without them needing additional therapy for a long time. And that was actually the original indication for ibrutinib, was patients who had what we call relapsed CLL, often after these conventional therapies.   

Katherine Banwell:

Hm. Let’s turn to medication management. Excuse me. With oral medications available to treat CLL, patients now have the role of self-administering with their treatment program. How does this work exactly? 

Dr. Jean Koff:

So, just as you would receive a prescription from one of your doctors to manage your high blood pressure with a bottle of pills, you would also receive a special prescription from the doctor who is managing your CLL, a prescription for one of these oral agents. Either the BTK inhibitors or a venetoclax. And you would be – you would have the instructions on the pill bottle, just as you would you know another prescription and you would take the medication by mouth, every day, as instructed. 

Katherine Banwell:

Okay. What happens if a patient forgets to take their medication? Does it impact efficacy? 

Dr. Jean Koff:

So, forgetting a dose for one day, or having to skip a dose for another reason, or even a few days, shouldn’t have a major impact on controlling the CLL. And that’s true for two reasons. One, you’re going to start taking your medication again, you know fairly soon after you miss that dose. The next day. Or – or in a few days. But also, the – what we call the half-lives of these drugs are relatively long, and so you have some activity of the drug in your system in its ability to control the CLL, even though you haven’t taken the dose that you missed that day. In fact, sometimes we have to hold CLL medications.   

Maybe you’re getting a procedure, some sort of surgical procedure, and you might be at an increased risk of bleeding just in the day or two before and after that surgical procedure, so we would actually recommend that you hold a BTK inhibitor, if that was what you were receiving for your CLL, and then resume it once your risk of bleed had gone down a few days after the surgery.  

Katherine Banwell:

Hm. 

Dr. Jean Koff:

We do recommend that if you are going to miss a dose of your medication that you let your clinical team know, just so they can instruct you on how to resume your dose if you haven’t already gotten instructions from them about that. 

Katherine Banwell:

Okay. That’s really helpful information. What strategies are there to keep on schedule and remember to take the medication on time and regularly?  

Dr. Jean Koff:

So, I think these strategies are good whether you have CLL or some other type of disorder that you’re taking medication for. My patients often use labeled pill boxes with days of the week and a.m. and p.m., so that you know whether you took your pill that day and what time of day you took it. And so, setting that out for the week can be very helpful in organizing and making sure that you can check back and remind yourself whether or not you took your pill. 

Katherine Banwell:

How are patients monitored during treatment? 

Dr. Jean Koff:

So, your doctor is going to monitor you more closely when you first start a medication. So, I typically monitor my patients within one or two weeks of them starting an oral drug. One to make sure that they’re feeling okay on it, that they’re not having any side effects when they first start, but also to check lab values and make sure that the – the oral medication isn’t causing any problems with their blood counts or with other labs. Then, once we’ve established that they’re doing well on the medication, maybe they’ve come in every couple weeks for a month or six weeks, we start to space out those visits.  

I usually see my patients who are on active therapy about every three to six months to check and see whether they’re feeling okay, whether they’re having any side effects from the medicines, like I said to check their labs, make sure the medications aren’t causing any lab abnormalities. And also in the longer term, to make sure that their CLL is under good control on – on the medications. Because that’s one of our main goals is to keep the CLL under good control.  

Katherine Banwell:

We received another patient question prior to the program. Has there been any progress in helping CLL patients get a better reaction from COVID vaccines? 

Dr. Jean Koff:

That is a great question, and that is one that is near and dear to my heart and my colleagues at – at Emory. You raise a really good point, which is that CLL patients have altered immune systems just by virtue of their CLL. The CLL cells exert their influence on other immune cells and can cause your immune system not to respond to infections or immunizations the way it normally would. That’s without any medication in the mix. Now, when we look at patients who are on medications like the ones we’ve been talking about, the BTK inhibitors, venetoclax, but especially the monoclonal antibodies that react against CD20, we see that those patients really do not have an optimal response to vaccines, especially the COVID vaccine. 

Meaning, that patients who receive the COVID vaccine while they’re on that therapy, or even within twelve months of receiving a monoclonal antibody, often don’t mount the same strong immune response as somebody who’s not on those therapies. So, luckily, we – we don’t have to just depend on the vaccines. I still recommend that my patients get vaccinated, because it is safe and it might impart a little bit of efficacy, and it’s certainly more effective than not getting the vaccine. But we also have other approaches to increasing your protection against COVID, including the – the injection called Evusheld, which can help protect patients specifically whose immune systems are not completely normal and are not expected to mount a strong response to COVID vaccines.  

So, that is definitely a discussion to have with your doctor about how your medications impact your protection from COVID, from vaccines, and whether there are other medications that might be used to help increase your protection.  

Katherine Banwell:

That’s great advice. Dr. Koff I’d like to get your thoughts on where we stand with progress with helping people live longer and truly thrive with CLL. What would you like to leave the audience with? 

Dr. Jean Koff:

So, I think that one thing to remember with CLL is over the past few years we’ve seen an explosion in how we manage the disease because we have newer agents and therapeutic combinations that are helping people control their CLL for much longer than was possible 10 or 15 years ago. We still have a long way to go because ideally, we want every patient to be able to control their CLL and thrive with CLL for as long as possible. And, right now like I said before, we are not curing patients yet. Meaning that we don’t have a therapy that can get rid of the CLL, make it go away, and keep it away forever.  

That’s where clinical trials come in. That’s where we are able to make progress, is we’re able to study what therapies work, what therapies don’t, how they perform against each other, how they make patients feel, and what sort of side effects might be associated with them. And so, that’s really the next step, is continuing the work that has already been done in clinical trials and exploring these new therapeutical approaches.

Okay, let’s meet our guest today. Joining me is Dr. Adam Kittai. Doctor, welcome. Would you please introduce yourself?  

Dr. Kittai:

Thanks for having me. My name is Dr. Kittai, I’m an Assistant Professor at the Ohio State University, and I specialize in research and clinical research in Chronic Lymphocytic Leukemia.   

Katherine:

Great. Thank you so much for taking the time to join us today.  

Dr. Kittai:

Happy to be here.  

Katherine:

I understand that CLL researchers met recently at the annual American Society of Clinical Oncology meeting, also known as ASCO, to share their research. Are there highlights from the meeting that patients should know about?  

Dr. Kittai:

Yeah, so this time of year, there are two main conferences actually that are very important to the CLL groups at large, as well as the oncology community. So, there’s ASCO and then there’s EHA, the European Hematology Association. And in general, there was a lot of exciting things at both of these conferences. 

In CLL, we have two main treatments that we’re really focused on. One is called the BTK inhibitors, which is ibrutinib, acalabrutinib, and zanubrutinib that you may have heard about. And the other treatment regimen is called venetoclax, and that’s usually paired with something called obinutuzumab. So, right now we’re either using the BTK inhibitors or the venetoclax as our frontline therapies. And typically, when patients progress on either one of those treatments – their disease gets worse – we switch to the other one. 

And so, what I’m getting to be that right now, that paradigm of starting with one therapy – the BTK inhibitors or the venetoclax – and then switching to the other, or vice versa, is being challenged. How that’s being challenged is combining the two medications together to see if combining them together is better than giving them sequentially. So, I think this is the primary research that’s being looked at in the world of CLL and we got some updates to show that the combination of the BTK inhibitors, plus the venetoclax, is looking quite good. It’s looking like it’s inducing deep remissions in some of our patients.  

Some of the challenges here though that we still need to figure out is that a lot of these combinations are leading to more toxicity. So, ultimately, I think we’re going to have a discussion about who is the appropriate patient for the combination, as opposed to giving it sequentially. 

There’s also a lot more research going on, looking at what we call randomized trials, which we’ll get to in a second, to determine if the combination is better than giving it sequentially. Right now, we just have what we call single-arm studies that kind of show safety and how well the trial works. But really, the definitive clinical trials – and once again, we’ll get to this a little bit later – are going to be randomized study where we randomize patients to the combination versus the sequential therapy to determine if doing it together is better than doing it sequentially.  

So, I would say that this new treatment paradigm of combining our two main treatments up front is looking quite good. We’re worried about some of the toxicities when we combine these medications, and we’re still not quite sure if combining them is the right approach, if it actually is superior to giving them sequentially. So, I think that’s the name in research right now for CLL, whether or not combination therapy is better than sequential therapy. The jury is still out, but some of the new data we saw was exciting. 

Katherine:

So, how can patients stay up to date on research like this as it develops? 

Dr. Kittai:

Yeah, great question. So, for one, you can talk to your physician. A lot of the physicians will go to either ASCO or the European Hematology Association and be able to come back with some of this data to share with their patients. And then also, there’s a lot of smaller conferences that local oncologists will go to get highlights from these particular conferences, where they also will come back to the patient to let them know some of this highlighted research. I think that’s probably the easiest way for patients to get access to this research. And Google’s our friend, right? And so, a lot of things are available on Google if you know where to look for them. 

Katherine:

Right. So, a key part in moving forward with CLL research is clinical trials, right? So, for people who may not know the term, what is a clinical trial? 

Dr. Kittai:

Yeah. So, a clinical trial is an experiment where patients are enrolled to receive a treatment that is either new or new in a new setting – so, an old treatment in a new setting – and we’re looking to see whether or not the treatment leads to improved outcomes for our patients.  

Katherine:

Why would a CLL patient consider participating in a trial? What’s the benefit for them? 

Dr. Kittai:

Yeah, great question again. The benefit of a clinical trial is two-fold. One is that by participating in a clinical trial, we are collecting data to determine what’s best for patients moving forward. [00:07:06] So, in a way, by participating in a trial, you’re contributing to the benefit of CLL patients in the future to help us determine what’s best for everybody moving forward. That’s one reason to go on a clinical trial. Another reason to go onto clinical trials is that it allows for access to therapies that may not be available otherwise, which may work better than what we already have and may be safer.  

Katherine:

Right. So, I’d like to walk through a few common questions that patients have about clinical trials. And here’s a concern we received from a patient prior to the webinar. “I’m nervous that I will receive a placebo if I join a clinical trial.” So, first of all, would you define a placebo?  

Dr. Kittai:

Sure. A placebo is usually a sugar pill or something that has no effect. That’s what a placebo is.  

Katherine:

And is it true then, would a patient possibly get a placebo in a CLL clinical trial? 

Dr. Kittai:

Not typically. So, in terms of clinical trials for CLL, we have a lot of treatments that are effective and safe in CLL. And so, we don’t typically design trials where you’re not getting some kind of active therapy. It would be extremely rare, and I don’t know of any trials currently that involve patients getting a placebo for CLL. Because it wouldn’t be ethical for us to enroll a patient on a trial where they would get a placebo instead of active therapy. 

Katherine:

Right. That makes sense. Here’s another question from an audience member, and I think this is probably a common concern for patients. “Is a clinical trial only something I should consider if there are no other options?” 

Dr. Kittai:

So, in my opinion, you should always consider a clinical trial, even if there are other options. And it’s because of those two reasons that I mentioned earlier. Number one, it benefits the CLL community as a whole to participate in the trial so that way doctors and researchers can collect data to improve outcomes for patients with CLL. And also, even though our drugs currently work really well, we don’t know how well they’ll last for, right? So, they still don’t know for certain how long our current drugs are going to work for in the future.  

And we’re always trying to do better. We’re always trying to create some sort of treatment, some sort of treatment paradigm that might be safer, as well as work better, and either of those goals is approvable. All of our drugs come with toxicity, right? And even though they’re really safe and they work really well, we’re hoping to develop something that is even safer and works even better.  

Katherine:

Yeah. It sounds, then, like trials can be considered throughout a patient’s life with CLL. What concerns do you hear from your patients?  

Dr. Kittai:

Yeah, so I think the primary concern I hear about a trial and the difference between going on a trial and standard of care, is that typically for a trial, it does require a little bit more from the patient. Meaning that there’s usually more visits – whether it is to monitor the effect of the new medication or new medication combination on the patient, whether or not it’s affecting their laboratory values or how they’re feeling.  

Or there might be parts of the trial that require invasive procedures. So, for instance, many trials will require bone marrow biopsies where a standard of care won’t. And the reason why the collection of those bone marrow biopsies is important for the trial is to better get an idea of how the treatment is working on a patient’s body.  

So, I think those are the two primary concerns I hear from the patient. Number one, it typically is a bigger time commitment with more visits to the doctor because we have to closely monitor the patients while they’re on trial. And number two is sometimes the trial involves procedures that otherwise wouldn’t be indicated for standard of care.  

Katherine:

Let’s talk a bit about how trials work, starting with the phases. What happens at each phase?  

Dr. Kittai:

There are actually four phases of clinical trials, although three phases are typically what’s talked about. So, Phase I is when we are first introducing the new medication, the combination, or the old medication in a new scenario for the first time in a human being.  

Phase one encompasses a lot of different things. It could be a first in-human phase one, where we’re giving the drug for the first time in a human being. It could be, as I said, the combination of drugs being used for the first time in a human being. Or it could be that we have this drug that works for this other cancer and we’re trying it out on this new cancer. So, we might have experience with this drug in another scenario, but not in the scenario we’re trying to do.  

And the primary purpose of the phase one clinical trial is to see if it’s safe. So, that’s the primary purpose of a phase one clinical trial – see if this new medication, this old medication in this new scenario, or this new combination is safe to use going forward.  

Katherine:

Right. 

Dr. Kittai:

We are able to see if it works to a small degree in the phase one trial, but typically these trials are very small with somewhere between 10 to 50 patients. And so, it’s hard to know how well this works by looking at such a small amount of patients.  

Once the Phase I trial goes forward, we usually go onto Phase II. So, one of the other points about Phase I is to determine the correct dose. Usually in phase ones, we increase the dose of the drug slowly until it meets some sort of toxicity cut-off for our patients. So, once that dose is discovered, then we move onto Phase II, and Phase II is usually a small study, usually about 50-100 patients where we’re looking at preliminary efficacy, to see if this drug, this new combination, or the drug in a new scenario, is actually working.   

And so, Phase II will tell us we think it’s working and if it looks good in phase two, it gets moved onto Phase III. Phase III is the final part of the drug development, where if it passes Phase III, it usually gets approved by the Federal Drug Administration. And Phase III is usually a randomized trial where you’re giving the new drug, the combo, or the old drug in a new situation, and you’re comparing it to whatever’s used as standard of care in that particular scenario.  

Katherine:

Right. 

Dr. Kittai:

And that’s usually a randomized study where patients are either getting the new thing or the old thing. And then, we’re determining which one works better. Lastly is Phase IV, and this is post marketing. So, after a drug gets approved, the drug company and the FDA requires just a wide scope of just data that’s collected to see how well the drug is working and if it’s safe once it’s brought out to the wider community.  

Katherine:

Okay. You mentioned randomized clinical trials. There are a couple of other clinical trials as well. Would you define them and tell us how they’re different from one another?  

Dr. Kittai:

Yeah. So, a randomized trial is when you enroll onto a study, and you get randomly assigned to either the experimental arm or the control arm. The experimental arm is that new drug that we talked about. And the control arm is usually the standard of care. So, that’s a randomized study. 

And randomized studies are usually Phase III trials, but they can be phase two in some scenarios as well. You have – usually that’s paired with a randomized control study. So, a control study is just there’s a control arm, that’s what that means. But those usually go hand in hand. Those are usually together.  

And then another trial is the double-blind clinical trial. So, a double-blind clinical trial means that once you’re randomized to either the experimental or the control, neither you nor the physician know what drug you’re taking. And that usually is not used in CLL trials. Usually, we know what drug the patient is assigned to. And the reason why that is, is because oftentimes we’re looking out for specific adverse events or toxicities of the drugs we’re implementing at Phase III.  

And then, also, if you’re getting a triplet versus a doublet, meaning three drugs versus two drugs, it’s very hard to blind somebody to know which drug they’re on because obviously you’re getting three drugs versus two drugs. Or if an infusion is involved in one arm but not in the other arm, you obviously know that you’re getting an infusion versus an oral drug. 

Katherine:

Ah, okay. Are there common clinical trial terms that you think patients should know about? 

Dr. Kittai:

I think we covered most of them. So, knowing that phase one is typically the first in the sequence of events that I would ask your physician if this was a first in human study, right, because that comes with some special considerations knowing that you are the first human to receive a new drug is very important. Versus a phase three study where, you know, you know this drug has already gone through phase one and two in development, meaning it’s been given to a lot of patients, and they’re just looking to see if it’s better than standard of care. So, I think knowing those general concepts about what’s the difference between a phase one and a Phase III study, it’s very different. I think it’s important to keep those in mind when talking about clinical trials and discussing with your doctor.  

Katherine:

Patients often have questions about safety. What are the risks of clinical trial participation?  

Dr. Kittai:

Yeah, so before anybody enrolls onto a clinical trial, you should sit with your doctor to talk about the pros and cons of entering this clinical trial. One of the things that they will talk to you about is what the expected safety of this drug is. So, you might ask yourself, well, if it’s a phase one study, first in human study, how do they know what toxicity to expect? 

Katherine:

Right. 

Dr. Kittai:

The answer is that there’s a lot of pre-human studies that occur, both in mice and monkeys and other animals, and researchers often have a good idea of what to expect in human. But there is a lot of unknowns in a phase one clinical trial. And after discussing with your doctor the pros and cons of going on a clinical trial and what side effect profile to expect from whatever drug or combination that you are about to be using, usually you go through a consent.  

Usually, you’ll get a packet, it’s about 10 to 20 pages long, written in a way that patients can understand. And it’ll have a list of toxicities that are associated with the research that is occurring. In terms of knowing what adverse events might happen, the consent is key, because it’ll have those all listed out.  

And also having the conversation with your physician about either what they’ve experienced giving this clinical trial, or what is to be expected after this drug had been introduced pre-humans.  

Katherine:

Mm-hmm. Are there protocols in place to protect patients? 

Dr. Kittai:

Yes. So, remember how we talked about in the phase one trials, we dose escalate the drug until we’ve reached some toxicity limit? There are specifically rules written out in a protocol that the doctor must follow that ensures safety for the patients that enroll in clinical trials. And that dose escalation part where we reach a toxic limit is a key part of those phase one trials that is spelled out before you even enroll.  

Usually, there’s also something called a Data Safety Monitoring Committee, as well as other committees that are looking at patients as they are receiving these drugs and move forward on clinical trials to make sure that the investigators are following the protocol as printed. That if anything happens, they document why it happened and fix the problem before it becomes another problem for a patient. So, there are very specific safety rules and a lot of redundancy to protect our patients, because the number one priority is to protect the patient. 

Katherine:

Yeah. I think you’ve already answered this, Dr. Kittai, but how do you know the medicine is safe before a human trial even begins? 

Dr. Kittai:

The answer is you don’t. There is some risk. As I said, they do test it in animals before they give the drug to humans, and they usually start at the lowest dose possible. But there are certain circumstances where there are surprising side effects that are not expected. And so, when you’re entering a first in human, Phase I trial, that is a specific risk that you do need discussed with your physician about before you enroll. 

Katherine:

Can a patient change their mind once they’ve enrolled in a clinical trial? 

Dr. Kittai:

Always. Always.  

Katherine:

Okay. 

Dr. Kittai:

They can come off the clinical trial at any point if they choose to.  

Katherine:

Okay. Now that we know what trials are and how they work, how can people find out what trials are available to them? 

Dr. Kittai:

Yeah. So, I’ll come back to this, but once again, talk to your physician. They’ll know what clinical trials are available at whatever site you are seeing them in. If there’s a local academic sector, the academic sector typically has clinical trials available there as well. So, it’s always good to get a second opinion in that regard.  

But one of the open access places that you can find all clinical trials is clinicaltrials.gov. This has all active running clinical trials listed out and anyone can access it. There are other societies out there that often post about clinical trials. So, there’s the CLL Society. It’s a website that you can check out that has a lot of information on there about active clinical trials in CLL. There’s also The Leukemia & Lymphoma Society, the Lymphoma Research Foundation, they all have websites available that have a lot of clinical trials listed and how to access them.  

Katherine:

Are there key questions that you think patients should ask their health care team about participating in a trial?  

Dr. Kittai:

Yeah, for sure. I think one of the key questions to ask is, is the control arm appropriate. So, what do I mean by that? Sometimes people who design a clinical trial will design a trial where the control arm is an easy control arm to beat, meaning that it’s a treatment that we wouldn’t necessarily put you on as standard of care.  

And so, I think this is a real question and an honest question that you should ask your physician prior to enrolling on a trial is, is the control arm something you would give me as standard of care. And if the answer is no, you should really consider not going on that trial or talking about why you would want to go on that trial if the control arm is not something they would put you put you on as standard of care.  

Katherine:

Right. 

Dr. Kittai:

That’s, I think, a key question to ask. And again, asking what phase it is and understanding where we are in the development.  

Katherine:

What do you feel are the barriers to accessing clinical trials for patients?  

Dr. Kittai:

So, unfortunately, a lot of clinical trials are at academic centers, and so there are – and the reason that is, is that the academic centers have the infrastructure to run the clinical trial. So, as we have mentioned before, there’s a lot of visits with a lot of extra science and labs that are done associated with the clinical trial. And a lot of those things and the coordination can only be done at large centers that can open clinical trials and know how to run them.  

Similar explanation could be that that safety monitoring committee that I’d mentioned before, where the academic centers have the infrastructure to ensure safety for the patients. So, access to academic centers is a limitation to enrolling in clinical trials. That being said, there are a lot of centers that are associated with an academic center and do have a lot of the clinical trials that are available at the academic center.  

And there are also cooperative groups. These cooperative groups are called Alliance and ECOG and SWOG. And these cooperative groups are national groups that are headed by multiple academic centers in partnership with pharmaceutical companies and they typically run large Phase III medical trials that help redefine standard of care. And those particular clinical trials are often available at private practices as well.  

Katherine:

Oh, that’s great. So, patients don’t necessarily have to think about traveling to a large educational institution then to become part of the clinical trial?  

Dr. Kittai:

Not always. Not always. Typically for the Phase I, the answer is yes. But for Phase III trials, usually there’s a lot of access available for Phase III trials.  

Katherine:

What would you say to patients who may be hesitant about participating in a trial?  

Dr. Kittai:

I would say that it’s important to at least ask about what’s available. And knowing what’s available and the risks and benefits of going on a clinical trial is how you should make the determination if you should go on a clinical trial.  

Remember what I said earlier that the clinical trial is really meant to help improve safety or efficacy. So, we don’t open clinical trials that we are not hoping to improve one of those two things. And so, that is something that we should be able to put in words to you when inquiring about the clinical trial. What is the goal of this trial, and why do you think it’s going to improve safety or efficacy? And the physician who’s talking the trial with you about it should be able to answer those questions for you. So, if you have some hesitance about going in clinical trials, I would say gather your information first before making a final decision.  

Katherine:

Some patients worry about the financial aspect or impact of a clinical trial. Aren’t trials expensive?  

Dr. Kittai:

So, actually, most clinical trials are less expensive than enrolling a standard of care. So, this is actually a benefit of going on a clinical trial. Often times, the drugs in the clinical trial are a cover. So, that’s something to ask too. And so, if somebody’s having trouble getting access to novel therapy that is looking good in a specific cancer, a clinical trial is actually a way to get access to that drug without paying for it.  

Also, all clinical trials when they’re being developed are looked at by the finance committees of the hospital or wherever it’s being developed. All standard of care options are billed through the patient insurance, but all the extra stuff is usually covered by the pharmaceutical company that’s enrolling those patients onto the trial. Or I should say the supporting the clinical trial, excuse me. 

Katherine:

That’s really good information to have.  

We touched on research at the top of the program, but are there other areas of research that you’re excited about and that patients should know about? 

Dr. Kittai:

Yeah, so one of the things that I think is being really talked about in cancer care – and medical care in general – is if disparities exist between minority patients and white patients. And I think this is a really, really important topic.   

So, the American Society of Clinical Oncology, which had the conference recently, really made this a mainstay point of the conference this year and there were a lot of abstracts that were defining whether disparities exist and hopefully, by defining whether disparities exist, we’re able to target those disparities in order to make outcomes equal for all of our patients.  

So, in the CLL world, one of the things that I alluded to is a lot of our therapies can be really expensive. So, these new therapies are really expensive, they really widen the disparity gap for patients who are minorities, as well as patients who come from socioeconomic status.  

Katherine:

Absolutely. 

Dr. Kittai:

And so, there were two abstracts. One was an oral presentation that looked at the National Cancer Database in ASCO that showed that Black patients do have worse overall survival than white patients. And then, I actually did my own study looking at the SEER database, which also showed the same exact thing. Even when controlling for socioeconomic status.  

So, I think addressing these disparities, making sure that there’s equity amongst our patients, that everyone has access to these drugs and can afford them, especially when they make our patients live longer and are safer than chemoimmunotherapy in CLL is very, very important.  

Katherine:

Dr. Kittai, if a patient feels like they’re not getting equitable care, are there resources available for them?  

Dr. Kittai:

Yeah, so one of the things that I love about the CLL society, is that they have a section called Access an Expert, I believe. So, look on the website, I’m not sure it’s actually called Access an Expert, but it’s a way for all patients to get a second opinion from one of the CLL experts listed on the website. And so, if somebody is feeling like they’re not getting access to the most beneficial treatment, for whatever reason, seeking a second opinion and using the CLL Society’s website to find that second opinion, I think would be a great way for someone who feels that way to get access to the care that they deserve.  

I believe there are other ways to do this through the Lymphoma Research Foundation, as well as LLS. But I know for sure on the CLL Society, there is a link that you can click that you can get access to a second opinion.  

Katherine:

Yeah. I’m glad you brought that up. As we wrap up the program, Dr. Kittai, I’d like to get your final thoughts. What message do you want to leave the audience with related to clinical trial participation?  

Dr. Kittai:

Yeah. So, I would say that in the last ten years, there’s been a revolution in the way we treat CLL, and we wouldn’t have gotten here without clinical trials. So, the reason why we have the BTK inhibitors – the ibrutinib, acalabrutinib, and zanubrutinib – and the reason why we have the BCL-2 Inhibitor venetoclax, and the reason why these have changed the way that we treat CLL making our patients live longer with better safety profiles is because of clinical trials. And so, I am a firm believer that if we can enroll a patient onto a clinical trial that’s appropriate, who might benefit from the trial, then they should enroll in the clinical trial if possible.  

So, I strongly encourage everybody to enroll onto clinical trials, to get access to, you know, groundbreaking new therapies. And once again, I want to highlight that the point of a clinical trial is to improve safety or to improve efficacy and that’s why we develop clinical trials and that’s the hope by running it.  

Katherine:

Okay, that’s great advice. Dr. Kittai, thank you so much for joining us today. It’s been a pleasure.

CLL Treatment Approaches: What Are the Types?

Transcript:

Katherine:

There’s not necessarily a one-size-fits-all approach to treating CLL, so how do you decide which treatment is right for a patient?  

Dr. Coombs:

I always look at their underlying disease biology. There’s a couple really important tests that I send for all of my CLL patients by the time that they need therapy. The first is to see what their underlying cytogenetics and molecular findings are. There are certain good findings, and then certain bad findings.  

One of the bad findings is having a deletion in the 17th chromosome in the short arm of that chromosome. The chromosomes are the big pieces of DNA within everyone’s cells. There are findings that are common in CLL: a 17p deletion is a poor prognostic feature. There’s a separate test where we can actually identify mutations in a gene called TP53. And these behave largely the same as 17p deletions, so I always check for both. It’s two different tests.  

Oftentimes patients have both of these findings: a 17p deletion and a TP53 mutation. But sometimes you can have the mutation without the deletion and vice versa. That is one finding that’s important when talking about different therapies. The other really important prognostic test is the IGHV gene mutation status. This is another specialized sequencing test. It looks to see if the patient’s heavy chain, if their immunoglobulin protein has undergone something called somatic hypermutation or not.  

It’s actually good to be mutated. What we know about people who are mutated is that they typically have better responses to most therapies and their disease typically is one that grows slower. So, I use those factors and then I have a conversation with the patient. The two main treatment classes that I spoke about – so the BTK inhibitors, those work actually really well and even the people with these bad prognostic features.  

So, people with the 17p deletion, people with the TP53 mutation, they can have disease control for six plus years on a BTK inhibitor, which is really good.  

That was not the case a decade ago when we didn’t have these drugs. That’s something that’s been hugely beneficial for our patients. The venetoclax/obinutuzumab regimen, that still works when people have the 17p or the TP53, but it probably doesn’t work as well.   

I’d mentioned the median time for disease to come back hadn’t been reached yet. It had been reached for that poor risk subset. The expectation for people with that poorest marker is that the median PFS, progression-free survival. So, again, when after someone starts therapy, when the disease then progresses is 49 months. It kind of gives me a rough estimate of, “Gosh, these are your therapy options and based on your underlying biologic factors unique to your disease, this is what you can expect out of therapy A or therapy B.”  

The mutated or unmutated IGHV, similarly, those BTK inhibitors work extremely well, even in people with the bad unmutated finding. I think those are always an option. The other treatment is an option, but the people with that bad finding do have a shorter time until they progress of just under five years.
