Lisa Hatfield:

Welcome to this START HERE Patient Empowerment Network program. This program bridges the expert and patient voice, enabling patients and care partners to feel comfortable asking questions of their healthcare team. I’m Lisa Hatfield, a cancer survivor and also an Empowerment Lead at Patient Empowerment Network. Joining me today is hematologist-oncologist

Dr. Kami Maddocks, Professor of Clinical Internal Medicine in the Division of Hematology at The Ohio State University Wexner Medical Center. Dr. Maddocks specializes in treating patients with B-cell malignancies, including non-Hodgkin’s lymphoma, Hodgkin’s lymphoma, and chronic lymphocytic leukemia. Dr. Maddocks researches new therapies for these hematologic malignancies, largely through evaluating new targeted therapies in clinical trials. Thank you so much for joining us, Dr. Maddocks.

Dr. Kami Maddocks:

Thank you, Lisa. It’s a real pleasure to be here with everyone today and talking about follicular lymphoma, and I just really appreciate you having me.

Lisa Hatfield:

The world is complicated, but understanding your follicular lymphoma diagnosis and treatment options along your journey doesn’t have to be. The goal of START HERE is to create actionable pathways for getting the most out of your follicular lymphoma treatment and survivorship. Joining us are patients and care partners facing a follicular lymphoma diagnosis, some of which are newly diagnosed, in active treatment, watch and wait, and also living for years with their disease.

START HERE is designed to provide easy-to-understand, reliable, and digestible information to help you make informed decisions. I’m thrilled you’ve joined us. Please remember to download the program resource guide via the QR code. There is great information there that will be useful during this program and after. Okay, Dr. Maddocks, let’s start here. What is the latest in follicular lymphoma, and what are the most important highlights for patients and families?

Dr. Kami Maddocks:

When we look at some of the stuff that’s changed in follicular lymphoma, there has actually been some really exciting developments just in the last year in follicular lymphoma. So when you look at patients who have relapsed or refractory follicular lymphoma, we’ve actually seen the approval of three different new therapies just in the last year for relapsed/refractory follicular lymphoma. So one of those therapies, we saw a brand new approval, and that’s a therapy which combines an oral targeted therapy with a monoclonal antibody.

So the combination of the CD20 antibody, obinutuzumab (Gazyva), in combination with the BTK inhibitor zanubrutinib (Brukinsa) was approved in March of 2024 for patients with relapsed/refractory follicular lymphoma. And this was based on a study that compared that to the single agent anti-CD20 antibody. So while we have had CD20 antibodies approved in both original treatment for follicular lymphoma and relapsed disease, it was the first time that we’ve had a BTK inhibitor approved for the treatment of relapsed/refractory follicular lymphoma.

In May of 2024, we saw the approval of actually the third chimeric antigen receptor T cell or CAR T-cell therapy for relapsed/refractory follicular lymphoma. So previously, we’ve had two different CAR Ts that target the same antigen or protein CD19 on the cell. And the third therapy with the same target was approved in May of this year for relapsed/refractory follicular lymphoma. And then in June of 2024, we actually saw the approval of the second bispecific antibody for the treatment of relapsed and refractory follicular lymphoma.

So previously, we had one approved almost two years ago in December, and a second one, epcoritamab-bysp (Epkinly) was approved in June of this year for patients with relapsed/refractory follicular lymphoma. So three different treatments approved in this setting in the last year, which increases the options for patients. It also provides us with thinking about sequencing these agents. And there’s a lot of studies ongoing to decide or to think about what is the best way to sequence therapy, because there’s no right or wrong answer currently in which therapy did you choose and when in patients with relapsed/refractory follicular lymphoma.

And then thinking about managing when we’re choosing these therapies, what are the side effects of these therapies and managing these side effects? Right? Because chemotherapy is often used for patients with initial diagnosis, and there is very specific side effects to chemotherapy and ways to manage those side effects. But when we look at some of these newer therapies, we have to think about the different toxicity profiles that they have and how we manage those toxicities.

So when we’re thinking about the newer therapies, like bispecific antibodies and CAR T-cell therapies, there’s very specific toxicity with those therapies, including cytokine release or CRS. And then something called ICANS, which is immune effector cell-associated neurologic toxicities, which are neuro side effects of these therapies. And so how do we identify and manage those therapies and now even looking at ways to potentially prevent patients from having those specific toxicities.

Lisa Hatfield:

Okay, thank you. So regarding those toxicities, like the ICANS and the CRS, is there a difference in how you treat patients? For example, if a patient might experience those side effects, are they hospitalized for that type of treatment initially, or are all of these new treatments done on an outpatient basis?

Dr. Kami Maddocks:

Yeah, that’s a great question. So the answer can be variable depending on the specific product or the center where the patient’s receiving them, and then even the disease that they’re used in. So let’s just talk about bispecific antibodies to start. So the first bispecific antibody that was approved in follicular lymphoma was mosunetuzumab-axgb (Lunsumio). There’s no required hospitalization to administer that, but there is a recommendation that if patients have signs or symptoms of cytokine release.

So the primary symptom is fever. That’s the number one most common symptom that patients will get and how we define cytokine release. But patients can also have hypoxia or a drop in the oxygen or hypotension and a drop in their blood pressure. So if they have these, it’s generally recommended that they’re admitted for a period of observation to ensure that those toxicities don’t worsen or escalate and that they’re treated if they do.

Which treatment can include ruling out other causes. Some patients may need antibiotics if they have low blood counts and a fever. Some people will need fluids and oxygen. Then sometimes we use steroids like dexamethasone (Decadron) or even cytokine blockers to help manage those side effects, particularly if they’re what we call higher grade or more significant. The second bispecific antibody epcoritamab-bysp. That was previously approved in diffuse large B-cell lymphoma and there was a recommended hospitalization with a step-up dosing for that.

However, in follicular lymphoma, when they studied that, they gave an extra dose. So part of trying to prevent the cytokine release is giving a lower dose and then increasing the dose each week until you reach the maximum dose. So they added an extra kind of intermediate dosing in the follicular dosing and showed that that made a lower risk of…a lower number of patients had cytokine release. And that the majority of them had the lowest grade cytokine release.

So in follicular lymphoma, it’s actually with that increased one dose in there to get to the maximum dose. It’s actually not recommended, or it’s not required that patients are hospitalized for any of the doses. But, of course, if they would, same thing, if they would have side effects, then you would consider that. And then the same thing could be said for the CAR T-cell therapies. Some of them are given inpatient and then patients are monitored for a period of time, and then some are administered as an outpatient. And patients are seen daily for that to check on how they’re doing, monitor for side effects, have labs. And sometimes it just depends on the center administering the therapy, how they have a setup for patients to be monitored.

Lisa Hatfield:

So I have two follow-up questions to that overview. Are these newer approved therapies, are they available at some of the smaller cancer centers, or are they only available right now at the larger cancer centers or academic centers? Then my second question is, are they limited duration therapies or like bispecific antibodies, does that just continue until disease progression?

Dr. Kami Maddocks:

Yeah, those are great questions. So in general, if you look at the combination of the obinutuzumab and zanubrutinib that should be able to be administered anywhere, the therapy for the oral therapy is continued until progression. If you look at the bispecific antibodies, there’s both. There’s a time-limited therapy, and then there’s one continued until progression. I think in general, we’ve seen that initially these have been used at larger treatment centers, but now that they’ve been approved for a while, we have seen a lot of these being used at smaller cancer centers and in the community centers. Sometimes patients may receive their initial dosing at a larger center and then transition to a local center. But I think, like I said, now, especially the one that’s been approved for a while, we’re seeing that it can be started at many places.

Lisa Hatfield:

Thank you so much for that important overview, Dr. Maddocks. All right, it’s that time where we answer questions we’ve received from you. Remember, as patients, we should always feel empowered to ask our healthcare providers any and all questions we might have about our treatment and prognosis. Please remember, however, this program is not a substitute for medical care. Always consult with your own medical team. So before we dive into this Q&A, since this program centers on coping with relapse and managing treatment side effects, how do you approach these first-time conversations with patients and their care partners who are facing relapse and potentially dealing with a new set of side effects due to the changes in their treatment regimen?

Dr. Kami Maddocks:

I think that’s a great question, and I think there are a lot of things to consider. So I think the first thing that we want to think about when we’re talking about patients having relapsed or refractory follicular lymphoma is that just because patients have relapsed or refractory follicular lymphoma doesn’t always mean that they need treatment. So many patients, when they’re initially diagnosed with follicular lymphoma, are going to go through a period of observation or watch and wait where we know that they have follicular lymphoma, but they don’t have symptoms of their disease.

They don’t have a large number of lymph nodes involved, or their lymph nodes are not very large by the scans, and they don’t necessarily need to be treated until they become symptomatic or have certain concerns from their lymphoma that’s causing problems. So the same thing can happen probably more with relapse than necessarily refractory disease, but patients may…you may detect on scans that they have lymph nodes that are growing or that their disease has recurred, but they don’t always necessarily need to receive treatment.

Once you’ve identified that, yes, a patient requires treatment for their relapsed or refractory follicular lymphoma, the next thing to think about is that patient and their disease. So what age is the patient? What were they treated with initially? Because not all patients receive the same initial therapy. So the decision about what they’re going to receive when they relapse is going to be somewhat dependent on what they received for their initial therapy, what side effects they had from that therapy, and how they responded to that therapy.

The next thing is going to be that there is not just one option at relapse so really discussing the different options for those specific patients, and what are the options, what are the side effects of those options, what is the treatment schedule of those options? Because some treatments may have more toxicity, but they’re time-limited, whereas other therapies may be continued to help progression, they may have less toxicity, but over time that’s a toxicity that patients continue to experience on a daily basis.

So really talking to the patient about the options, what does the schedule of that treatment look like? Do they have to come in weekly? Do they have to come in once a month? And then again, the side effects and how that fits into side effects that they had with their initial therapy, how they tolerate that, are any of those side effects still there?  For example, if a patient has neuropathy from their therapy, that might be something that lasts and then considering all those things and making an informed decision with the patient.

Lisa Hatfield:

Okay, thank you. And these questions are in the perfect order, because we have a question from Lauren asking you, what is the difference between relapsed and refractory? 

Dr. Kami Maddocks:

Okay, this is another great question. I’m sure all these questions are great. When we think of relapsed disease, we think of a patient who’s had therapy, got in a response to that therapy, that response has lasted some time, and then their disease recurs. When we think of refractory, we think of that more as patients that have received a therapy, and they haven’t responded. Now, there is no standard definition of refractory. So we all agree that if a patient gets a treatment and their disease does not respond to that treatment, they’re refractory to that treatment.

But there’s no defined time for which if a patient has a treatment and responds to that treatment but has a short relapse, what’s really considered refractory. In general, a lot of studies that look at a therapy say that if you’ve had it, like if you’ve had rituximab (Rituxan) and you’ve relapsed within a six-month time frame, that that’s refractory. But some studies use three months instead of six months.

Lisa Hatfield:

Okay, thank you. Another patient, Jeff, is asking, Dr. Maddocks, I’m currently in an observation stage of non-Hodgkin lymphoma. I get blood work twice a year and scans once a year. I’m hoping it stays slow-growing. How long on average can a person live in observation mode before treatment must occur?

Dr. Kami Maddocks:

So this is another great question. And I’m going to provide kind of an overview that we’ll kind of set up, because there may be more questions like this. But in general follicular lymphoma is not one disease, which I’m sure since this is a program focused on relapsed/refractory follicular lymphoma, a lot of patients have heard this and know this. But it’s what we call it’s very heterogeneous, or it can behave very differently in patients, meaning that some patients will have very indolent disease, and then there’s a small portion of patients whose disease will be more aggressive.

We know that when we diagnose patients with follicular lymphoma there are some patients that are diagnosed and require treatment pretty quickly, whereas there are other patients that go many years, many, many years without requiring treatment. Some of that is because of the disease, and some of that is because of how we find a patient’s follicular lymphoma. Some patients, we don’t find it until they present with symptoms. Some patients find their own lymph nodes, and some patients are diagnosed because they have a baseline scan that for a totally different reason, maybe get into a car accident, have scans to make sure nothing’s broken, you find an enlarged lymph node, you biopsy it, and you find this diagnosis.

All that said, there are some studies that have looked at patients who are on observation or watch and wait and looked at treating patients who have what we call low tumor burden, or not a lot of lymph nodes, or not very large lymph nodes, but have what’s called advanced stage disease. So lymph nodes on both sides of the diaphragm, not large enough to necessarily require more aggressive treatment, they don’t have symptoms. But we’ve treated, we’ve looked at studies treating those patients with observation or watch and wait or single agent rituximab (Rituxan) therapy. And when you look at the patients in those trials, the median time to needing treatment for patients from observation was three years.

However, there were 30 percent of patients, so one out of three patients who were still being observed at 10 years without requiring any therapy. So there are patients, that’s almost a third of patients at 10 years who’ve been observed, not required therapy in that population of patients. And certainly I have been practicing for a while where I’ve seen patients, I do have some patients who’ve gone longer than that without needing therapy.

Lisa Hatfield:

Okay, thank you. And there you go, Jeff, we hope that you’re in that third. 

Okay, thank you for explaining that. Next question, I’m not sure if it’s Jeff Run or Jeffrey is asking about the most common side effects that are associated with bispecific antibodies, and what precautions can be taken to reduce the risk of infection?

Dr. Kami Maddocks:

Yeah, another great question. There are two different bispecific antibodies that are now approved for relapsed/refractory follicular lymphoma. And I will take this time to also say that some of the exciting ongoing work is looking at those agents in clinical trials, in the frontline setting, in combination with other therapies particularly non chemotherapies.In general, I would say similar side effect profile. The most common side effect between them is the cytokine release or the CRS. So that is the most common side effect. Again, this can be defined in different ways. The most common side effects that you see from that define CRS are fever, hypotension or low blood pressure, hypoxia or low oxygen, shortness of breath, chills, tachycardia or higher heart rate. 

We have talked a lot about CRS and what it entails and how it is defined and presents. But management, it depends on what we call grading. So for patients who just, who have a fever, oftentimes, number one, you want to make sure that it is CRS and that there’s not an underlying cause. So ruling out infection or coexisting infection, if a patient is neutropenic or has a low neutrophil count and is at high risk for infection, you may treat them with antibiotics with a fever while you rule out infection.

But oftentimes, if they have a fever, you can manage symptomatically anti-fever medications like acetaminophen (Tylenol). If a patient has worsening CRS and has other symptoms associated with it, such as the hypoxia, low oxygen, or hypotension, low blood pressure, then that’s when we escalate therapy. So one you direct treatment towards that. So if they need fluid, if they need oxygen, but then that’s when you’re thinking about starting medications such as the steroid medication. So we give intravenous dexamethasone, or there are certain cytokine blockers such as tocilizumab (Actemra) that can be given to help treat the side effects of the cytokine release.

Other common side effects or that we’re seeing in more patients in the clinical trials, fatigue, rash, and then infections including upper respiratory infections, and then COVID-19 infection as well. So part of treatment of these side effects is early recognition of the side effects. So patients are monitored closely and that you’re dealing with the side effects to help them from worsening. I think infection prevention is very important with these. So it’s recommended to consider prophylaxis for certain infections. So antiviral medication to prevent viral, such as shingles reactivation, medication to prevent a specific type of pneumonia, PJP pneumonia, and then consideration I think of just making sure that patients are up to date on vaccination. And if patients do have infection while they’re getting treated, potentially delaying treatment or taking a break in order for them to recover from treatment.

Lisa Hatfield:

Okay, thank you. And this person did not give their name but is asking, Dr. Maddocks, I wanted to know how to travel as safely as possible. Is it advisable to get certain vaccines for travel like yellow fever? I plan to travel to Europe via plane and cruise. They say that there’s stage III non-Hodgkin’s follicular lymphoma getting treatment every eight weeks.

Dr. Kami Maddocks:

So this is a great question, and I’m probably going to answer this a little bit more generically, because I think that it can depend a little bit as far as what specific vaccines. But when thinking about travel, I think that it’s a good idea to look at where you’re traveling because both, where you’re traveling time of year you’re traveling and what you’re going to do when you’re somewhere can depend on what vaccines are recommended. I usually advise patients to consider looking at the CDC guidelines for recommendations for what should be received in that area, travel that time of year, what they’re going to be doing.

And then sometimes there are places that will actually have a travel clinic. Once I know what vaccines are recommended, the patient knows what vaccines are recommended, then I usually work with them and pharmacy to decide what vaccines, if they can receive all those vaccines or if there were certain ones that we may not recommend. In general, it can depend on a patient, what treatments they’ve received or if they’re actively receiving treatments. But in general, we like to avoid live virus vaccines in our patients. So I take into all those factors and then would recommend discussing the specifics with your physician.

Lisa Hatfield:

Luca is asking what are the long-term side effects of bispecific antibody treatment, and how will I be monitored for them after treatment ends?

Dr. Kami Maddocks:

So another great question. I think, when we think about the side effects in general, the bispecific antibodies in the CAR T both have those unique toxicity, cytokine release being the most common. And then you also have worry about the neurological toxicity. The difference is that, depending on the specific, bispecific or CAR T that you use, but we usually, typically see these occur in lower grade or not as severe with a bispecific antibody than you can see with a CAR T-cell therapy.

You can still have cytopenias and infection risk with these therapies. Whereas in chemotherapy, we think of that as more generalized toxicities, with the cytopenias, with the risk of infection with the GI toxicities. When we think about long-term side effects, so I think one of the important things to recognize is that bispecific antibodies have not been around that long in the scheme of things, though we can’t say, the risk of 20 years, what do we see or even 10 years.

But when we think about what we have seen, we’ve seen things like the cytokine release, the infections, the cytopenias, but what we haven’t seen is things like the secondary malignancies that we worry about when we think about chemotherapy or even maybe immunomodulatory therapy or secondary cancers that patients can develop. I think for long-term monitoring, right now, at least the biggest thing you want to think about is that these therapies do deplete the lymphocytes, for a prolonged time. And so the risk of viral infections or reactivation of infections, and making sure that’s being considered.

Lisa Hatfield:

Okay, thank you. That’s an important question. So another may possibly be a care partner, Marilyn. How can I best support my loved one during relapse and what should I do if I notice my husband with new or worsening symptoms?

Dr. Kami Maddocks:

So another great question. I think it’s first of all important to ask the physician about what symptoms to watch for. So you know, are there certain worsening new symptoms or worsening symptoms that seem more likely to be related to follicular lymphoma versus something else. I think it’s always important to encourage your loved one if they are experiencing new symptoms to reach out to the physician so that they can be evaluated. Because follicular lymphoma is a disease that many people live with and many people live with it for many years. We know that patients can experience other things.

Not everything is going to be just because of the follicular lymphoma. So it’s important to be evaluated, and recognize what is going on and what is attributed to the follicular lymphoma. I think being supportive, thinking of questions to ask and making sure that those questions are answered. I think thinking about, are there resources available? I think educating yourself is one of the most important things that people can do. So knowledge is power. So just participating in things like this I think can be very helpful, because learning about what’s out there, knowing that there are many options, I think being supportive and having a positive attitude, are all helpful things.

Lisa Hatfield:

Okay, thank you. So we have another big and important question from Aubrey. How can I live a full life with follicular lymphoma while managing the emotional toll of knowing the disease may relapse? And what lifestyle changes or habits should I focus on to maintain my health during remission?

Dr. Kami Maddocks:

Yeah, so this is another great question, and I think there’s probably lots of different ways to answer this or lots of different things to consider. So I think in general, as we’ve talked about follicular lymphoma is something that people live with for a long time. So thinking about just your general health and general disposition. So, we want to think about incorporating exercise, incorporating a healthy lifestyle, thinking about exercise, and being physically active.

Thinking about particularly diet and not saying that there’s any food that you need to avoid or any specific thing, but I think eating healthy is important. I think sleep hygiene is, can be very critical for patients. I think finding, and then just general health, it’s good to have a PCP so that you’re getting good routine health maintenance. We have to think about making sure that we’re managing other medical things like blood pressure, glucose, looking, doing other routine cancer screenings, depending, if somebody’s male or female, but the screening that’s recommended for that.

Now when we’re thinking about managing this does take an emotional toll because a lot of times, when somebody’s initially diagnosed, if they don’t need treatment, the question is always like, well, how long am I, is it going to be before I’m going to need treatment? How am I going to tolerate that treatment? How long is that treatment going to last? And then that resets once a patient’s had treatment. Well, how long will I stay in remission for this treatment? What’s going to be next?

I think things that can help with that are, sometimes I think involving like psychosocial oncology, I think support groups, I think that it’s very beneficial for many patients to talk to people, whether it be through a u look at the median age at diagnosis is in the 60s, and median overall survival is greater than 20 years. So many patients are going to live with this more like a chronic disease. And so learning to kind of knowing basic facts on what it is, what are the treatments that are available, what do those treatments look like, what are the reasons that you need those treatments? And that you are able many times in those periods of not needing treatment to live a very normal lifestyle and do things. I think making sure that, I think it’s important.

One thing that I think can be helpful is you’ll continuously follow up with your physician. So thinking about questions and concerns that you have throughout the period of time, writing them down that gets them out of your mind on paper. And then when you go to see your doctor next, you have that list of questions. Because I think, sometimes we think about things, and then we worry, worry, worry. But putting them down on paper or even sending them through like a secure MyChart email message and then talking them out, because a lot of times if you don’t do that, then when you go to see your physician you think, oh, I don’t really have any questions.

And then you leave and you’re like, oh, I should have asked these 10 different things. So again, I think asking for resources. So there are many different patient friendly resources out there. I think reading material that’s been written or vetted by medical professionals as opposed to just any random material can be very helpful for patients. And then again sometimes seeking out kind of peer support.

Lisa Hatfield:

Okay, great, thank you. Sean is saying that he was diagnosed with follicular lymphoma in 2022 and in an active treatment. What advice do you have for someone transitioning from patient to survivor? I am eager and fearful.

Dr. Kami Maddocks:

Awww. Well, another good question. And I think one thing I want to recognize is that somebody with cancer is defined as a survivor from the time they’re diagnosed moving forward. So you’re already a survivor. But when you, I do think, and I tell patients this, even when we’re talking about starting treatment, I do think that being aware of kind of where patients are at mentally is important.

Because when you go through, when a patient goes through treatment, they’re very focused on next steps and next steps when you’re going through treatment are, when’s my next treatment going to happen? When’s my next scan going to happen? When you get to that point, when you’re done with treatment, you no longer have those small milestones that you’re reaching the next treatment, the next scan. You now are like, oh my gosh, I had this treatment and now, how long is it going to last?

What’s going to happen to me? What else can happen to me? And there can be a lot of fear and anxiety. I would first tell you that’s totally normal. That is a normal feeling to have at this point. So I think one, recognizing that you have them is important. I think considering things like we’ve talked about, is there a survivorship clinic, is there psychosocial oncology? Is there something that might help in talking those things out? I think setting up milestones, what is the next thing? I’m going to have a three-month appointment, I’m going to have labs.

These are the things I need to be thinking about, but if I’m not noticing these also, what things can I do to return to the things I like to do. I think also I would go back to saying, I think this is where just thinking about getting good sleep, getting exercise, eating a healthy, balanced diet, and then socializing and making sure that you’re involving friends and family.

Lisa Hatfield:

Okay. Thank you. And, Sean, you’re already a survivor, Dr. Maddocks said so. So good luck, Sean. All right, Dr. Maddocks, thank you so much for being part of this Patient Empowerment Network START HERE program. It’s these conversations that help patients truly empower themselves along their treatment journey. On behalf of patients like myself and those watching, thank you so much for joining us, Dr. Maddocks.

Dr. Kami Maddocks:

Well, Lisa, thank you so much for having me. It’s been a real pleasure, and I hope everybody has a great day.

Lisa Hatfield:  

Thank you. I’m Lisa Hatfield. Thank you for joining this Patient Empowerment Network program.

Transcript:

Lisa Hatfield:

I did a little research last night before I talked with you, and it sounds like that is something that the CAPTIVATE trial is investigating. A patient asked about that, what that trial is. And it’s music to my ears as a cancer patient to hear something like “fixed duration”, it’s also investigating a fixed duration so patients and have maybe a bit of a medication vacation. So can you speak to that trial a little bit and explain what it is a little bit on how that might benefit patients with CLL?

Dr. Ryan Jacobs: 

Yeah. So one of the best elements of treating with venetoclax (Venclexta) is that it produces a deep level of remission in many patients. In fact, when given with the monoclonal antibody obinutuzumab (Gazyva), to CLL patients receiving that treatment as a first line of therapy for their CLL, about three-quarters of CLL patients will get to so deep of a remission that we call them minimal residual disease negative.

Lisa Hatfield: 

And that’s a blood test or a bone marrow test, but more easily done as a blood test, where we can look to a sensitivity of one in 10,000 white cells and determine if there’s any CLL in those 10,000 cells. We can actually go deeper than that, but we say, we CLL patients are negative if they’re less than one in 10,000. And so 75 percent of patients will get to that depth of remission just with obinutuzumab for six months along with venetoclax for a year.

Dr. Ryan Jacobs:

So when researchers saw that, they recognized that we could probably stop treatment in those patients getting venetoclax because venetoclax yields these deep responses. And then the next kind of thought was, well, could we give a BTK inhibitor with venetoclax, but also over a defined treatment timeline and maybe get some of the remarkable benefits of treating with a BTK inhibitor but not get stuck being on therapy for years and years.

So the CAPTIVATE study was the first really to, in a large Phase II manner, look at that combination in a younger patient population, it was for patients 70 and younger. And it wasn’t in a high risk or anything, it was all comers. But they did have to be 70 and younger and getting treatment as a first-line therapy. So the combination was very effective. As of the last American Society of Hematology meeting in December, four years of data was reported and a large percentage of patients were still free of progression, over 80 percent still free of progression. And that’s three years off therapy at that point.

It was well-tolerated, not many patients had to come off due to toxicity. It was in fact, less than 10 percent had really significant toxicities requiring discontinuation. So it was a well-tolerated effective treatment.

I do have one of those studies to open at my institution, the acalabrutinib-venetoclax combination,  it’s called the MAJIC trial, and it is a large Phase III study that if it’s successful, I think would lead to the approval of giving those two drugs together. But then the extra credit question is, who should get the combination and who should get the drugs separately? And we don’t have an answer for that right now, and that’s a long topic of debate among CLL specialists. 

Lisa Hatfield:

Great. Well, thank you. So for that trial you spoke of that you’re conducting right now, is that… Is it only relapsed patients who are eligible for that? Or is that for front-line therapy.

Dr. Ryan Jacobs:

No, this is a first-line therapy that the MAJIC study is.

Lisa Hatfield: 

Oh good. That’s promising for patients too.

Dr. Ryan Jacobs:

And it has a really good comparator arm, so that won’t be a problem that the standard arm on that study is venetoclax (Venclexta) plus obinutuzumab, so it’s comparing against one of our best treatments, and so we really will get the answer of does it look better to use the BTK with the Bcl-2? Or is it not really that much better than just giving a venetoclax with obinutuzumab? And then the one obvious element that I didn’t mention that would be nice for most patients in addition to being efficacious and well-tolerated is if you could get an all-oral combination. Of course, venetoclax with obinutuzumab, you’re still getting quite a few infusions with the obinutuzumab over the first six months. So that’s a lot of time in the infusion center that you could avoid with just the combination of two oral targeted agents. So that would be a breakthrough for patients too, I think.

IGHV-Mutated vs IGHV-Unmutated CLL | What’s the Difference

Is It Aging or My CLL?

Is It Aging or My CLL?


Transcript:

Lisa Hatfield:

There’s a lot going on in terms of novel therapies and new options. But before we jump into all of that, the tool box that’s expanding, can you introduce CLL and provide an explanation of what it is and what that means for a newly diagnosed patient?

Dr. Ryan Jacobs:

So chronic lymphocytic leukemia, or CLL, is the most common chronic lymphoma/leukemia. It is really both most of the time. It presents with what we call lymphocytosis, meaning the white blood cell count, and specifically the lymphocyte count is high or elevated. To call it CLL, to make that formal cancer diagnosis, we can generally take a patient’s blood sample and put it through a fancy machine that we call a flow cytometer, that looks for characteristic markers on the outside of the cells, and if there’s a bunch of those cells, we call that a monomorphic population.

So a bunch of those cells that look the same, and they’re B cells, that’s the type of lymphocyte count they are, and they’re over this threshold of 5,000. Then that is the diagnosis right there, we don’t need an invasive procedure. You generally do not need a bone marrow biopsy or a lymph node biopsy. There is in about 15 percent of cases, the disease presents with just in large nymph nodes, and the white count is normal. We call that small lymphocytic lymphoma. It’s considered an overlap with CLL, and I’ve had many patients that have started off with SLL and then eventually manifest elevated lymphocyte count later in their disease course. So it is considered an overlap, the treatment is the same for both of those disease entities.

So that’s the diagnosis of CLL and how it generally shows up initially. In a nutshell, it’s a cancer of the aging population, average age is 70. I have a lot of patients that ask me, “Why did I get CLL?” And the answer is, “We don’t know.” It’s that way with most cancers, unfortunately, we don’t know why one person gets a cancer and the other person doesn’t.

But it obviously has something to do with the aging effect on the DNA of the B lymphocytes because of how much more common it is as patients get older. 

Lisa Hatfield:

We know that therapies are evolving faster, hopefully faster than patients are relapsing, which is a good thing. So when they do relapse, chances are there will be a new option for this patient. But a CLL cure still remains elusive.

So, Dr. Jacobs, if you can speak to…we’ll just jump right into some of the newer, the novel therapies and things that are being investigated with CLL treatment. If you can just speak to some of those newer therapies, the novel pathways and targets that are currently under investigation with CLL, we’d appreciate that.

Dr. Ryan Jacobs:

Sure. We’ve come a long way in how we are managing this common cancer that’s benefiting a lot of patients. And as mentioned, with this cancer being one that is more common in the older population, we do know that the population of the United States specifically is getting older, there’s going to be more 70-year-olds. So these breakthroughs are helping a growing number of CLL patients.

Before 2014, really outside of a clinical trial, the only way we could treat CLL Is with combinations of chemotherapy and an immune therapy, like a monoclonal antibody called rituximab (Rituxan), that was kind of our first, what we would call targeted treatment outside of chemotherapy that we had, and it was, like targeted treatments are, well tolerated. It was an antibody that targets B cells specifically.

So we were combining it with chemo, we would call that chemoimmunotherapy, and it helped a lot of CLL patients. But for many, those were poor prognostic markers in particular, and those with relapse disease, chemotherapy was not very helpful, and it was quite toxic in many circumstances.

So we’ve been fortunate that since 2014, we’ve had a lot of new treatment options, and they’re targeted therapies. It’s not like non-specific cytotoxic chemotherapy, these are treatments that have been developed with specific targets in mind that are unique to the B-cell neoplasm, the B-cell cancer, the CLL. And the first of these that really changed everything was a BTK inhibitor called ibrutinib (Imbruvica), that we got in 2014.

Initially, we can only use it in the relapse setting, but eventually, in 2016, we could start treating patients as a first line of therapy with ibrutinib.  And then in 2019, we had a newer version of BTK inhibitor, we call those second-generation BTK inhibitors. That drug was acalabrutinib. And it eventually was shown in a head-to-head study to be just as effective as ibrutinib in a relapsed patient population, but it had less side effects than ibrutinib. So in, specifically, atrial fibrillation, hypertension. Cardiac toxicities overall were one that they really focused on in that study.

So as a whole, when we were choosing BTK inhibitors, we were shifting away from ibrutinib, shifting to acalabrutinib, and then just as…earlier this year, we had a third BTK inhibitor, zanubrutinib (Brukinsa), that was approved. It’s also considered a second generation BTK inhibitor like ibrutinib and acalabrutinib (Calquence). It treats CLL in the same way, in how it inhibits BTK or Bruton’s tyrosine kinase, that’s over expressed in CLL cells.

But it also has a favorable toxicity profile when compared head to head with ibrutinib, and now we have two second-generation options between acalabrutinib and zanubrutinib. And it’s not really easy for us to know between those two, which is “better.” When we decide to treat with a BTK inhibitor, we’re usually choosing between those two at this point, and we’re trying to personalize the decision for the patient, and there are some different factors they can get involved in that complicated decision.

Luckily, we are not limited to BTK as a target. I mentioned earlier, we have monoclonal antibody, rituximab like the one I mentioned, but a newer version of rituximab, a more potent version, obinutuzumab. Is one that we have available along with a Bcl-2 inhibitor, venetoclax (Venclexta). That is now, as of 2018, improved in the frontline CLL setting, also approved in the relapsed setting, of course, since 2016.  And we use venetoclax with a monoclonal antibody like obinutuzumab (Gazyva), and together they are a very potent combination that cause pretty rapid cancer cell death, as opposed to the BTK inhibitors that more put the cancer to sleep and require daily dosing indefinitely for as long as the drugs work.

And remarkably, the data on BTK inhibitors tells us that should work for many, many years. They’ve been following some of the patients that got treatment in the first line setting, and eight years out, there’s still more than 50 percent of the patients are free of progression, so they can’t even quote an average response time yet. With eight years of follow-up on the early ibrutinib patients.  The difference with venetoclax combined with a monoclonal antibody like obinutuzumab, is because it causes a more rapid cell death, you can give it on a time-defined schedule. So we tend to give it for one year in the first-line setting and two years in the relapse setting, and the antibody portion is just given for the first six months. 

The BTK inhibitors and venetoclax are oral treatments, so that’s a big win for patients to avoid the infusion center for those treatments, but the IV antibody treatments will still require some trips to the infusion center if you’re doing that combination with venetoclax. For most patients, those two targets are what we’re choosing between, and we try to personalize the decision to the patient. And again, that’s a very complicated discussion on what is “best.” And we use things like the prognostic work-up, medical problems that the patients already have, medicines that patients are on, to help make the best treatment decision for our CLL patients. But those…for in terms of how well that treats the CLL, both of those are considered equivalent options for the large majority of CLL patients.

We’ve got some things on the horizon, but in general, those are two targets that we have at this point. There is for relapsed patients, PI3 kinase inhibitors that are still FDA-approved at this time, that aren’t quite as effective and more toxic, so we sometimes think about using one of those targeted therapies if a patient has already progressed on a BTK inhibitor in venetoclax class. In the future, we are looking towards combining BTK and Bcl-2 inhibitor. Like, for example, there’s been studies already done that I’ve put many patients on, with ibrutinib-venetoclax, and I believe there’s a question about that later.

There’s also an ongoing study that I have opened at my institution that’s looking at acalabrutinib and venetoclax. So taking these two pills together in a time-defined manner, so you don’t have to take the BTK inhibitor indefinitely. And then there are some therapies that have already been improved in other lymphomas, and we wonder if they’re going to have a role in CLL eventually. So we now have bispecific antibodies, so that’s taking a drug like rituximab or obinutuzumab and adding a T-cell engager to it, so it has two targets or it’s bispecific.

And we have that drug, mosunetuzumab (Lunsumio) available in follicular lymphoma and there’s several others in development, and we’ll see how their role comes into play in CLL as well. As well as CAR T-cell therapy, where we take a patient’s T cells and genetically engineer them to attack the cancer. That’s now an approved therapy for many different kinds of lymphomas and multiple myeloma as well.

So we wonder if that’s going to have a role in CLL. But I think for the foreseeable future, it’s going to be looking first at BTK and then Bcl-2 inhibition, or vice versa. And we don’t really know which is better to go first, we think they’re both…they can both be sequenced one after the other. And then maybe it will have some of these other breakthroughs coming in and helping for after patients need something beyond those therapies.

And there’s probably going to be a lot of patients that never need anything beyond those options, those initial couple of targets, because they do so well. I think in the most immediate future, the approval that is going to give us a new great option is going to be for an alternative site BTK inhibitor, or it’s also called a non-covalent BTK inhibitor.

And there’s this drug called pirtobrutinib (Jaypirca), it has been approved in mantle cell lymphoma and likely will get approved in CLL this year. And that drug specifically is a BTK inhibitor that still works even in patients that have, say, progressed on ibrutinib or acalabrutinib or zanubrutinib. That will be a new target available for CLL patients and probably pretty quickly become one of the go-to drugs that we use for relapsed CLL patients that have already been treated with a BTK…with a traditional BTK inhibitor. So growing number of options and it’s really great for our CLL patients.

Lisa Hatfield:  

Hello and welcome. My name is Lisa Hatfield, your host for this Patient Empowerment Network program. In this important dialogue, we bridge the expert and patient voice 

to enable you and me to feel comfortable asking questions of our healthcare teams with more precision. The world is complicated, as is a cancer diagnosis, but understanding your CLL doesn’t have to be. The goal is to create actionable pathways for getting the most out of CLL treatment and survivorship. Joining me today is Dr. Ryan Jacobs, a CLL expert from Levine Cancer Institute. Thank you very much for joining us today, Dr. Jacobs, we really appreciate you being here and your time and expertise.

Dr. Ryan Jacobs:

Thanks for having me, Lisa.

Lisa Hatifield:

Before we get started, please remember to download the program resource guide via the QR code. There is great information there that will be useful during this program and after. Okay, let’s get started. So, Dr. Jacobs, I’d like to talk about what’s on the chronic lymphocytic leukemia radar, and rather than saying that entire phrase each time, I’m going to refer to it as CLL, because I’m pretty sure I’ll fumble that up. There’s a lot going on in terms of novel therapies and new options, but before we jump into all of that, the tool box that’s expanding, can you introduce CLL and provide an explanation of what it is and what that means for a newly diagnosed patient?

So it is considered an overlap, the treatment is the same for both of those disease entities.So that’s the diagnosis of CLL and how it generally shows up initially. In a nutshell, it’s a cancer of the aging population, average age is 70. I have a lot of patients that ask me, “Why did I get CLL?” And the answer is, we don’t know. It’s that way with most cancers, unfortunately, we don’t know why one person gets a cancer and the other person doesn’t. But it obviously has something to do with the aging effect on the DNA of the B lymphocytes because of how much more common it is as patients get older.

Lisa Hatifield:

Thank you for that overview, Dr. Jacobs. We do have CLL patients who are watching this who are newly diagnosed, they may be in active treatment, they may be in remission, they may be managing their CLL just fine right now in their lives. So we’re along the whole spectrum of CLL, so thank you for that overview. We know that therapies are evolving faster, hopefully faster than patients are relapsing, which is a good thing. So when they do relapse, chances are there will be a new option for this patient. But a CLL cure still remains elusive. So, Dr. Jacobs, if you can speak to…we’ll just jump right into some of the newer, the novel therapies and things that are being investigated with CLL treatment. If you can just speak to some of those newer therapies, the novel pathways and targets that are currently under investigation with CLL, we’d appreciate that.

Dr. Ryan Jacobs:

Sure. We’ve come a long way in how we are managing this common cancer that’s benefiting a lot of patients. And as mentioned, with this cancer being one that is more common in the older population, we do know that the population of the United States specifically is getting older, there’s going to be more 70-year-olds. So these breakthroughs are helping a growing number of CLL patients.

That will be a new target available for CLL patients and probably pretty quickly become one of the go-to drugs that we use for relapsed CLL patients that have already been treated with a BTK…with a traditional BTK inhibitor. So growing number of options and it’s really great for our CLL patients.

Lisa Hatfield:

Thank you for that overview again, Dr. Jacobs. It does sound like there are a lot of new therapies coming out, especially for relapsed patients, super exciting for them. And this is actually a great time to jump right into questions. We have many questions from patients that different patients have submitted. But first, I want to remind everybody that this program is not a substitute for medical care. Please consult with your medical team for advice on your own condition or disease. And, Dr. Jacob, I was taking notes as you were talking, because you had spoken a little bit about a combination of the BTK inhibitor and Bcl-2 inhibitor with venetoclax. And I did a little research last night before I talked with you, and it sounds like that is something that the CAPTIVATE trial is investigating. 

So that’s exciting, and a patient asked about that, what that trial is. And it’s music to my ears as a cancer patient to hear something like “fixed duration,” it’s also investigating a fixed duration so patients and have maybe a bit of a medication vacation. So can you speak to that trial a little bit and explain what it is a little bit on how that might benefit patients with CLL?

Dr. Ryan Jacobs:

Yeah. So one of the best elements of treating with venetoclax is that it produces a deep level of remission in many patients. In fact, when given with the monoclonal antibody obinutuzumab, to CLL patients receiving that treatment as a first line of therapy for their CLL, about three-quarters of CLL patients will get to so deep of a remission that we call them minimal residual disease-negative. And that’s a blood test or a bone marrow test, but more easily done as a blood test, where we can look to a sensitivity of one in 10,000 white cells and determine if there’s any CLL in those 10,000 cells. We can actually go deeper than that, but we say, we call patients negative if they’re less than one in 10,000. And so 75 percent of patients will get to that depth of remission just with obinutuzumab for six months along with venetoclax for a year. So when researchers saw that, they recognized that we could probably stop treatment in those patients getting venetoclax because venetoclax yields these deep responses. And then the next kind of thought was, well, could we give a BTK inhibitor with venetoclax, but also over a defined treatment timeline and maybe get some of the remarkable benefits of treating with a BTK inhibitor but not get stuck being on therapy for years and years.

So the CAPTIVATE study was the first really to, in a large Phase II manner, look at that combination in a younger patient population, it was for patients 70 and younger. And it wasn’t in a high risk or anything, it was all comers. But they did have to be 70 and younger and getting treatment as a first-line therapy. So the combination was very effective. As of the last American Society of Hematology meeting in December, four years of data was reported and a large percentage of patients were still free of progression, over 80 percent still free of progression. And that’s three years off therapy at that point.

It was well-tolerated, not many patients had to come off due to toxicity. It was, in fact, less than 10 percent had really significant toxicities requiring discontinuation. So it was a well-tolerated effective treatment.

I do have one of those studies to open at my institution, the acalabrutinib-venetoclax combination, it’s called the MAJIC trial, and it is a large Phase III study that if it’s successful, I think would lead to the approval of giving those two drugs together. But then the extra credit question is, who should get the combination and who should get the drugs separately? And we don’t have an answer for that right now, and that’s a long topic of debate among CLL specialists.

Lisa Hatfield:

Great. Well, thank you. So for that trial you spoke of that you’re conducting right now, is that…is it only relapsed patients who are eligible for that? Or is that for front-line therapy?

Dr. Ryan Jacobs:

No, this is a first-line therapy that the MAJIC study is.

Lisa Hatifield:

Oh good. That’s promising for patients too.

Dr. Ryan Jacobs:

And it has a really good comparator arm, so that won’t be a problem that the standard arm on that study is venetoclax plus obinutuzumab, so it’s comparing against one of our best treatments, and so we really will get the answer of does it look better to use the BTK with the Bcl-2? Or is it not really that much better than just giving an venetoclax with obinutuzumab? And then the one obvious element that I didn’t mention that would be nice for most patients in addition to being efficacious and well-tolerated is if you could get an all-oral combination. Of course, venetoclax with obinutuzumab, you’re still getting quite a few infusions with the obinutuzumab over the first six months. So that’s a lot of time in the infusion center that you could avoid with just the combination of two oral targeted agents. So that would be a breakthrough for patients too, I think.

Lisa Hatfield:

Well, you commented also on something that’s really important for patients to know, and that is that if you go into a clinical trial, you won’t be given nothing for cancer clinical trials, you’re going to be given the standard of care or whatever it’s being compared to. So for patients who are considering that.

Dr. Ryan Jacobs:

That’s a Phase III. Yeah, for Phase III. If you go on an earlier phase trial, you know exactly what you’re getting. There’s usually not any randomization for earlier phase studies, you just get the intended treatment.

Lisa Hatfield:

Okay, great. Well, thank you so much for explaining that. So we have some pretty specific questions, and we have a patient who wrote in and asked, “What is the difference between IGHV-mutated and IGHV-unmutated CLL? And can you talk about treatment considerations for those?”

Dr. Ryan Jacobs:

Yeah. So that’s part of a bigger discussion around the prognostic work-up of CLL and not all CLL is the same, and we’ve done a really good job of figuring out tests to separate out the CLL patients that tend to behave more aggressively and respond to certain kind of therapies, versus those that are more of what we call indolent or slow growing and respond to other kinds of therapies. I do want to say, I haven’t mentioned it yet, we still don’t treat CLL if it’s not causing any problems. And about half of patients get diagnosed as sort of an accident, and they get a blood test for something else, and their white count is elevated, and that leads to a diagnosis, but they feel fine. We still leave those patients alone. Even with these good treatment options we have, we recognize that there are a select percentage of CLL patients that don’t ever need treatment, and so we don’t just want to start treatment in everybody.

But I do still like to check this prognostic work-up, even if I’m not going to start treatment, but I make sure and ask the patient if that’s what…iIn line with what they want. But certainly, if you’re going to start treatment, you’re required by guidelines to check a prognostic work-up, and I would really encourage the CLL patients tuning in to ask their oncologist, “What is my prognostic work-up?” if they’re going to start treatment.  Because of the oncologists, unfortunately, that have to deal with lots of other cancers, maybe don’t always know the right test to send. I’m very spoiled in that I get to just treat lymphoma and specifically focus a lot of my research in CLL and get to stay up with all this. I don’t know how a general oncologist keeps up with everything, honestly.

But the big three tests are going to be the FISH analysis, fluorescence in situ hybridization. And then IGHV mutational analysis, and then also a TP53 mutation analysis. And I don’t really have time to go through all of those, but IGHV is the question I get a lot. “What is that?” It’s one of these rare findings where it’s actually normal to have a mutation at the IGHV. IGHV stands for immune globulin heavy chain variable region, and it is usually mutated in B lymphocytes because it’s part of the process of a mature lymphocyte that is able to make a lot of different kinds of antibodies. And it undergoes somatic hypermutation, is what it’s called, as the B cell matures. Generally in oncology, the more mature a cancer is, the less aggressive it behaves and usually the easier it is to manage, and that is the case with CLL. So think of an unmutated IGHV CLL cancer as a more primitive or a more immature cancer clone, and as such, it is harder to treat.

In about half of patients will be found to be unmuted at the IGHV and historically, all we had was chemo and we knew these patients weren’t going to respond for near as long as the IGHV-mutated patients were to chemo. What’s nice is, with our targeted treatments, particularly the long-term data with the BTK inhibitors, it doesn’t look like it matters whether you’re mutated or you’re unmutated. So that’s one of the really great things with our new treatments for CLL, is it has, the people that have benefited the most are the ones that were doing the worst, so that’s great. It’s not just the patients that were already doing well, that are doing even better.

Lisa Hatfield:

So I just want to take a step back and kind of looking at this through the lens of a newly diagnosed CLL patient. You’d mention that sometimes you don’t treat every CLL patient. So is there something, if you find a patient who does not need treatment, is there something you tell the patients as far as regular monitoring? Will you monitor them to see if it progresses to the point where it requires treatment?

Dr. Ryan Jacobs:

Yeah. And we’re fortunate that this is a blood cancer that most of the time we can follow with a simple blood count and follow the white count, follow how the…follow the health of the bone marrow by looking at things like anemia, low red cell count, or a low platelet count that we call thrombocytopenia. So that’s the easiest thing to follow, but I’m also talking with my patients and examining my patients. I want to know if their length nodes are causing them a lot of pain, because we should treat that, there’s no reason they should live in pain.I want to know if they’re waking up drenched in sweat all the time, if their quality of life has been really affected by that. Or are a dramatic amount of fatigue that we can’t explain by some other cause. And I also, of course, examine the nodes myself and make sure that there’s no alarming findings there. So that’s really what’s involved with checking on a CLL patient that’s on active surveillance, that’s what we call it. And there’s a list of criteria that the oncologist should know in terms of deeming who needs treatment and who doesn’t. And so we’re kind of following the same rules, so to speak, in terms of who gets treated for CLL.

Lisa Hatfield:

Okay, thank you. So we have a patient who asked a series of questions here, and I think you already…you spoke pretty well to the role of the BTK inhibitors in treating CLL. I’m going to kind of clump these together.  So I guess three questions. What treatments do you think are the most beneficial for patients whose CLL has relapsed? What are the poor prognostic indicators for CLL? And along the same lines, what are the high-risk genetic markers for CLL?

Dr. Ryan Jacobs:

It’s a little more complicated discussion in the first line setting because both are options. At this point in time, we haven’t been…at least those that are, I would say, staying up to date on the CLL data, we have not been using chemotherapy for a long time. So most of the relapsed patients will have seen either one of the BTK inhibitors or venetoclax. And so what we do in the second-line setting is just use the other option that they haven’t seen. The data tells us, when you look at what treatments are being prescribed, most patients are going on BTK inhibitors, and they have been around longer than venetoclax in general. So for a lot of patients, that relapsed treatment is going to be venetoclax. Because that has the best data in terms of treating patients that have progressed on a BTK inhibitor like ibrutinib or acalabrutinib or zanubrutinib.

In the near future, we’ll have pirtobrutinib (Jaypirca) and so maybe, maybe some will get that drug before venetoclax, and that’s probably okay. And so we’ll have that additional option. The complicated patients, and I’ve alluded to this, or what do we do after BTK and Bcl-2? What are we left with? I mentioned PI3 kinase, that’s not a great option. There’s still stem cell transplant out there for young patients that are running out of options. Clinical trial is really what I would like to emphasize there.  If you’re a patient that can get to a high volume referral cancer center with a CLL specialist, I would do that. If you have seen BTK inhibitor and venetoclax and are looking for other options.

Lisa Hatfield:  

Great, thank you. So the next question is actually a really good question, I think we can broaden it a little bit. But the question is, “How can I ask my doctor to make sure I am being tested for serum markers?” And more broadly, I think a lot of patients are a little bit nervous about asking questions of their doctor, because they don’t want to feel like they’re questioning their expertise or doubting them. So how in general can we ask our doctor questions if we hear something? Or how we approach our doctor with those types of questions?

Dr. Ryan Jacobs:

So I mentioned asking your doctor, “What’s my prognostic markers?” I think this is probably the easiest way to get that information. And your doctor should be checking those. The question comes up like, what are the “high-risk” markers? We talked about mutated versus unmutated. Thankfully, our novel treatments that doesn’t seem to matter. Same goes with…there’s on FISH there used to be, if you found three copies of chromosome 12, that’s called trisomy 12, that doesn’t seem to matter With our newer treatments. A deletion at chromosome 11, again, used to not do as well with chemo. Novel therapies…doesn’t seem to matter. The one that is still potentially affecting outcomes, even with our novel treatments, are chromosome 17 aberrations, which stately are rare in the initial diagnostic setting. That or a TP53. A deletion at 17p or TP53 mutation probably is only going to be around 10 percent of patients or so. And in the relapse setting though, that number goes up because of the more aggressive cancers emerge, we call that clonal evolution. So maybe in the 20-ish percent range. These patients, we tend to prioritize indefinite therapies first, because it seems like these patients do better if you keep treatment going, as opposed to interrupted therapies like venetoclax. And so we tend to treat those patients with a drug like acalabrutinib or zanubrutinib first and then think about the venetoclax later for those patients.

Lisa Hatfield:

Okay. Okay. And just to clarify, for patients too, I know that a lot of cancers, there are discussions about the 17 deletion, 17p, and then also the TP53 gene. So if I understand correctly, the TP53 gene is housed on chromosome number 17. So if that is missing, then that patient may be missing that gene, that is considered a tumor suppressor gene, which we want. Is that correct?

Dr. Ryan Jacobs:

Right. So it’s either missing, which is what we see on FISH with a deletion, or it can be mutated and that’s the next gen sequencing, and often it will be both in those patients.

We think with indefinite, there’s some really good data that was just released with zanubrutinib. When they looked at 17p-deleted patients, there’s some long-term follow-up with ibrutinib-treated 17p-deleted patients. With chemo these patients would only get about a year or so, but we’re getting maybe even close to normal outcomes with long-term BTK. But we do know if you just give them a year of venetoclax and obinutuzumab for six months and then stop, they do relapse quicker than the other patients. So they relapse after about four years. As opposed to with five years of follow-up with that first line venetoclax approach, there are 62 percent of patients are still free of progression.

Lisa Hatfield:

Oh wow, okay. Thanks for explaining that too. I know that that chromosome 17 and the TP53 gene, that’s talked about in a lot of different cancers and it often come up, “How are those connected?” So thanks for just describing that a bit. So this patient is asking, “For patients who may be eligible for BTK inhibitors, are there specific comorbidities that might contribute to adverse side effects?”

Dr. Ryan Jacobs:

Yeah, so we screen…all BTK inhibitors have some cardiac toxicity. They have been shown with the second-generation BTK inhibitors to have less cardiac toxicity than ibrutinib, specifically atrial fibrillation. So if you have atrial fibrillation, maybe that’s a reason why you might go on venetoclax first as opposed to a BTK inhibitor. But it’s not a contraindication to getting a BTK inhibitor if the atrial fibrillation is under good control.  Other cardiac risk factors would include difficult to control hypertension at baseline, or heart failure. These are all things that might make us think twice about using a BTK inhibitor as our first therapy, because venetoclax has no cardiac toxicities. The other thing to consider is BTK inhibitors all to a degree have, and I describe it to patients, like an aspirin-like effect on the platelets. They do interfere with the platelet binding, which so universally, patients will know to varying levels some easier bruising.

And if patients are on, because of say, they’ve had a heart attack in the past and they’re on aspirin at baseline, or what would even be more concerning if they were on a drug like Plavix because they’ve had a stent placed, that would be something that would really concern me and would definitely push me more towards venetoclax, that again, doesn’t have those anti-platelet interactions. Also, patients who are on blood thinners because of a history of blood clot or atrial fibrillation, there is the potential increased risk for bleeding and bruising there as well. None of these are absolute contraindications, they’re just all what goes into the blender, if you will, of putting lots of information in and coming up with the best treatment decision as personalized for the CLL patient. We’re blessed to have multiple options, but it does make it more of a challenge to find the “best” option.

Lisa Hatfield:

Yeah. Thank you for that. We have several questions from a couple of patients regarding side effects. So the question, “How long will my side effects of my CLL treatment last? And what can be done to reduce those?” And specifically, a patient is asking if there’s a connection with CLL and gastrointestinal issues?

Dr. Ryan Jacobs:

So all of the treatments, including venetoclax, the BTK inhibitors, will have diarrhea listed as a possible side effect. It’s usually low grade. But generally, I have found the gastrointestinal toxicities abate some over time. So if they are present earlier, if you’re able to stick with therapy, they do tend to get better. For the once daily meds, I encourage those patients to try to take the drug in the evening. The GI tract tends to be less active later in the day, and you can sleep off some of the potential gastrointestinal issues. So I’ve had success there. Sometimes we have to lower the dose to just find the best dose to help mitigate some of these. There’s the antidiarrheals that can help if you need them. Imodium. I had a patient I saw earlier this week that Imodium didn’t really work, but good old Pepto Bismol did the trick from time to time. So certainly though, if the gastrointestinal issues are significantly affecting quality of life, we need to come up with a new plan, whether that’s reducing the dose or changing to a different option. Specifically, what’s nice about the BTK inhibitors is they all have data that show if you’re having problems with one, you can switch to the other and likely not have the same problem occur. So that’s nice.

Lisa Hatfield:

Have you ever seen any uncharacteristic side effects several times in your practice? Anything really unique? I’m just curious about that.

Dr. Ryan Jacobs:

Yeah. There’s always the patients, they can have a more severe form of maybe, of a more common side effect, like the…we were talking about diarrhea, I’ve had a patient that actually had a difficult, with venetoclax, had difficulties with the stool incontinence. So that was kind of a severe form of that. It wasn’t so much diarrhea that was the problem. But we were able to ultimately mitigate that with a dose reduction. I would say the way, particularly if it’s an unusual side effect, the best thing to do is to take a break. If it’s a serious side effect that needs to be addressed and it’s affecting quality of life or causing problems, take a break from the treatment. If you take a week off these treatments, particularly venetoclax, taking breaks doesn’t matter. We like not to take long breaks with the BTK inhibitors. But if you take a week off, these drugs don’t have very long half-lives. So if the issue is not getting any better and you’ve been off of treatment for a week, it’s unlikely that that issue is coming from the treatment. So that’s a way I try to sort through some…particularly if they’re unusual side effects sometimes. And certainly, if we deem that the issue is connected to the treatment, I’ll usually try lowering the dose before just giving up.

Lisa Hatfield:

Okay. Thank you. A patient had asked, and I love this question because I often wonder myself when I get up in the morning, my bones are creaking and popping, “How do you know the difference between,” this patient’s talking about fatigue. How does a patient discern, “Well, this is fatigue from my cancer or my treatment,” versus just normal aging? Whether it’s fatigue or bruising or any side effect.

Dr. Ryan Jacobs:  

Yeah. Fatigue is a really…I had an attending physician when I was in my training that said, “Treating fatigue makes me fatigued.” But it’s hard. If it’s really the only problem the CLL patient is having, it can be. All those other problems I had mentioned earlier, the low red cells, the low platelets, the painful nodes, the night sweats, I with close to 100 percent certainty know I can fix those with treatment.Fatigue, I’m not as confident when that’s the only issue that a patient’s having. I try to differentiate between fatigue from other causes and old age, and specifically to CLL. 

They try to put it as a metric and say, if you’re having to spend half the day or more just lying around and you’re not able to do your normal activities of daily living, like that’s a severe level of fatigue and treatment should be considered.I’m looking for somewhat of a precipitous decline, not necessarily just kind of the gradual fatigue that you might more relate to aging. The problem with treating fatigue is you’ll look, if you look at the possible side effects of all of these medicines I talked about, fatigue will be a potential side effect.So you’re sometimes trading one problem and getting another, or maybe the fatigue does get better, but then the patient has some different side effect that’s even worse than the fatigue. So it’s hard to really help when fatigue’s the only issue. But certainly, I have helped some patients with fatigue. We don’t have a test that we can do to know for sure is the fatigue coming from the cancer, or is it coming from something else. 

Lisa Hatfield:

Great. Well, that wraps up our program for today. Thank you so much for joining us, Dr. Jacobs.  I am Lisa Hatfield from Patient Empowerment Network.

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.

Are There CLL Clinical Trials Studying Richter’s Transformation

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.

CLL and Anxiety: How Your Healthcare Team Can Help

Transcript:

Katherine:

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 (Calquence), the pirtobrutinib (LOXO-305), 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:  

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.

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.  

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

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.

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.
