Lisa Hatfield:

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 (Epkinly). 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:

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 (Gazyva) and zanubrutinib (Brukinsa) 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.

Dr. Kami Maddocks:

When we look at some of the stuff that’s changed in follicular lymphoma, there have 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.

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.

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.

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.

Lisa Hatfield:

Another question, Dr. Kahl. How do outcomes differ for patients with relapsed/refractory disease compared to those who respond well to initial treatment?

Dr. Brad Kahl:

So that’s a really good question. And when we have a patient going through frontline treatment, we’re all really crossing our fingers that that first remission is incredibly durable. Because when the disease relapses, the remissions do tend to get shorter and shorter and shorter, which is frustrating for everybody.And so we love it when we get a nice long first remission. And in the older days when all we had to offer was chemotherapy and some different immunochemotherapy regimens, the remissions in second line and third line might be two years or one year. 

It can get frustrating as you go through treatment after treatment after treatment. It’s hard on patients. The side effects start to accumulate. And that’s one of the reasons we’re so excited about all these new agents that we have for relapsed disease with the bispecifics and the CAR T products and the small molecule inhibitors like tazemetostat (Tazverik) and zanubrutinib (Brukinsa). Because it appears as though these remissions for relapsed disease might be getting longer than what we have seen historically. So there’s no question that dealing with relapsed follicular lymphoma is more difficult than dealing with frontline follicular lymphoma. But we’re optimistic that these newer treatments we have are improving outcomes for patients with relapsed disease.

Newly Diagnosed Follicular Lymphoma and Treatment Options

Newly Diagnosed Follicular Lymphoma and Treatment Options


Transcript:

Lisa Hatfield:

We have drugs that are oral, that are, we call them targeted agents, they hit like a molecular pathway inside the cell a lot, and they kill the cells a lot differently than chemotherapy does. And we have a number of new drugs that work through the immune system and try to attack the lymphoma that way.

Dr. Brad Kahl:  

So when we have patients who relapse, probably the most commonly used second-line treatment right now is a combination of a drug called lenalidomide (Revlimid), which is a pill that’s used in a few different cancers. It works very well for certain cancers, and it works well in follicular lymphoma. And that’s given with the immunotherapy drug called rituximab (Rituxan). And that was proven in a study to be very effective. About 80 percent of people will respond to the regimen, and that remission on average lasts in the two to three-year range.

So that’s probably the most commonly used second-line regimen right now in the U.S. for follicular lymphoma. And then there are a number of treatments that are now available in third-line and beyond that are new within the past, say three, four years. And these newer treatments that I’m about to describe are now being tested as second-line treatments and even as first-line treatments.

So it’s possible that some of these treatments I’m about to describe will become in the future, our go to regimens for first-line treatment or second-line treatment. And we hope they do move up, because that means they’re, it means they’re even better than what we’ve been using. So probably the treatments that we’re most excited about right now in follicular lymphoma are the drugs called bispecific monoclonal antibodies.

There are two that are now FDA-approved. One’s called mosunetuzumab-axgb (Lunsumio), and that was approved about a year-and-a-half ago. And the other one’s called epcoritamab-bysp (Epkinly), and that was approved just a month ago. And basically these drugs are infused or injected under the skin, infused intravenously injected under the skin and their proteins that will literally stick to the lymphoma cells. And when it does that, it kind of coats the cancer cells. And then after these bispecific antibodies coat the tumor cells, they literally will trick the patient’s T cells or healthy T cells to come in and attack the cancer.

So it’s a way of trying to trick the patient’s own immune system to come in and start fighting the cancer. And these two drugs are very promising in the relapsed setting. They work about 80 percent of the time to get some kind of response. About 60 percent of the time patients will go into complete remission, which means we can’t find any evidence for the lymphoma on scans. And they’re both so new that I don’t think we have a full understanding of how durable these remissions are going to be right now.

It looks that like about, if you do get a complete remission, that about half of those patients are holding that complete remission at two and three years. But we’re, we don’t know about four years and five years yet because the drugs are too new. And we expect that if, as these drugs move up and are tested in the second-line setting and in the first-line setting, they’ll work even better because the cancer cells tend to be easier to kill in earlier lines of therapy. Other agents that have moved into the relapsed follicular lymphoma space would include CAR T-cell therapy.

This is a fairly sophisticated complicated approach where you actually will run the patient’s blood through apheresis machine and you will extract the patient’s T cells and those T cells get genetically modified in a lab and then expanded and then are shipped back to the center and then re-infused back into the patient. So now again, we’re tricking the patient’s T cells into fighting their B-cell lymphoma.

And there are three CAR T products that are now FDA approved for use in follicular lymphoma, and they have very high response rates. With seemingly good durability we’re now getting three and four-year follow-up for these CAR T products with about half of people still in remission. The CAR T products probably have a little more toxicity and a little more risk than the bispecifics. So I think most of us are thinking we would try the bispecifics before CAR T, but there might be certain patients where a CAR T strategy is more appropriate to use before a bispecific.

So we’re very excited to have these tools in our toolbox. It’s always good to have more options. And then I should just mention the small molecule inhibitors. So here’s an example. Just this past year there was approval for a small molecule called zanubrutinib (Brukinsa). It targets an enzyme called BTK or Bruton’s tyrosine kinase. This is a pill really well tolerated. It’s given in a combination with an immunotherapy drug called obinutuzumab (Gazyva).

This zanubrutinib-obinutuzumab combination got FDA-approved just this year for recurrent follicular lymphoma. The results look very good for that. It’s very well-tolerated. There’s another oral agent called tazemetostat (Tazverik), which was approved a couple of years ago. It targets a mutated protein in follicular lymphoma. This is, again, is a pill super well-tolerated, very few side effects. So, there’s just a few examples for you of all the different treatment options we have for follicular lymphoma that has recurred after initial treatment.

And believe it or not, the decision-making can be difficult when you have so many choices and so many good choices, that’s a good problem to have. And I find myself a lot of times spending a lot of time with the patient and their family as we talk through these different options, and we try to think what’s best for them at this point in time, talking through the pros and the cons, how active it is, what side effects do we need to be concerned about. And it’s a lot for patients to digest when you have so many choices. But like I mentioned that’s actually a good problem to have.

Lisa Hatfield:

I think you’re right. There’s a lot of hope in those options. I do have two follow-up questions. One of them is when you talk about lenalidomide or brand name Revlimid, CAR T bispecific antibodies, this new small molecule, are these all quality of life is so important for cancer patients. Are these all limited duration treatments for recurrent disease when there’s a recurrence of the disease, or are they long-term treatments for the disease?

Dr. Brad Kahl:

Yeah, really good question. And the answer is different for every agent. So I’ll try to just kind of run through the list. For the CAR T products, the three different CAR T products, it’s like a one-time treatment and then you’re done because the cells that get infused will persist in the patient’s body for months and months and months. So they’re infused and then the cells will hang around a long time acting on the cancer. So for the CAR T it’s a one-time treatment. For the bispecifics, the mosunetuzumab-axgb product is a time-limited treatment that is done in less than a year. The epcoritamab-bysp is designed to be given indefinitely.

So those are, there are some pros and cons of those two agents, the two small molecules that I mentioned, the zanubrutinib is meant to be given indefinitely and the tazemetostat is meant to be given indefinitely. And then the first one I mentioned was the lenalidomide. That is in follicular lymphoma that it was developed to be given for 12 months in this setting. So the duration of therapy is unique for each of the different agents that I mentioned.

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 health care team. Joining me today is hematologist-oncologist Dr. Brad Kahl, Professor of Medicine in the Division of Oncology at the Washington University School of Medicine and Director of the lymphoma program at the Alvin J. Siteman Cancer Center in St. Louis, Missouri. Thank you so much for joining us, Dr. Kahl.

Dr. Brad Kahl:

It’s a pleasure. Thanks for having me, Lisa.

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. No matter where you are on your journey, this program is designed to provide easy to understand, reliable, and digestible information to help you make informed decisions. And most of all, we’re asking questions from you. 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. Let’s start here. Dr. Kahl, there is a great deal going on in the follicular lymphoma landscape, and I want to dig into that. But before we do, as is custom for this program, I’d like to start with a brief overview of this disease. What is follicular lymphoma? And can you break it down a little bit, the key differences between Hodgkin and non-Hodgkin lymphoma and how follicular lymphoma fits into that?

Dr. Brad Kahl:

Sure. The terminology can be kind of confusing to patients, so I’ll try to explain it. Hodgkin lymphoma is a specific kind of lymphoma. Non-Hodgkin’s lymphoma just means it’s not Hodgkin’s. So non-Hodgkin’s lymphoma is just a big, broad, descriptive term. It’s like saying automobile. But there are lots of different kinds of cars, obviously. So follicular lymphoma is a specific type of non-Hodgkin’s lymphoma. So it’d be like saying Chevy Malibu or something specific within that automobile term. So there’s like 100 different kinds of non-Hodgkin lymphoma. Follicular lymphoma is one of those. A

nd it’s kind of a unique answer biologically and clinically. Follicular lymphoma is characterized by this particular mutation inside the cells that sends a signal to the cells that says don’t die. So instead of being a disease of rapid cellular proliferation and growth, it’s more of a disease of slow cellular accumulation. If people can picture that, the cells are just accumulating slowly. So it’s kind of a slow-moving cancer. And probably when patients are diagnosed, they’ve probably had it for a long time already.

They just didn’t know it, because follicular lymphoma often doesn’t cause symptoms. And usually when we get a patient with newly diagnosed follicular lymphoma, the disease is very widespread. And that obviously makes people fearful. And so we spend a lot of time trying to reassure them that’s not a problem that’s typical for follicular lymphoma. Everybody wants to know their stage, of course. And I try to tell them, the stage doesn’t really matter that much in follicular lymphoma. In some cancers, the stage is a big deal. But those are cancers that you can kind of remove surgically.

But there’s really no role for surgery as a treatment in follicular lymphoma. The disease is typically very widespread in diagnosis, meaning it’s all over the body. And so when we do treat it, we pick treatments that will work everywhere. And our treatments tend to work just as well when the disease is at a more advanced stage. That’s why as the doctors, we don’t spend too much time worrying about the stage. It’s just not, it’s not as important in follicular lymphoma.

Lisa Hatfield:

Okay. Thank you. And just to clarify, when you mentioned that there is a mutation or often mutations in follicular lymphoma, is that in the cancer cells themselves, or is that in a mutation, like a BRCA mutation that a patient can be tested for? I presume it is.

Dr. Brad Kahl:

Right. That’s a great question. The mutation is specific to the cancer cells. So people are not born with this mutation. It’s not a mutation that you pass along in your family to children. It’s a mutation that is acquired in these cells at some point in the patient’s lifetime. Another confusing term is this whole idea of B-cell lymphoma or T-cell lymphoma.

And just to try to clarify that. So we have different kinds of lymphocytes in our body, and these lymphocytes, they have jobs to do as part of our immune system. And one kind of lymphocyte is a T cell, and that has specific roles in our immune system. And another kind is a B cell, and that has specific jobs to do in our immune system. Follicular lymphoma is derived from a B cell, a B-cell lymphocyte. So the…a B cell gets this mutation, and that turns it from a normal healthy B cell into a follicular lymphoma cell.

Lisa Hatfield:  

Okay. Thank you for explaining that and for that overview. That’s really helpful. I appreciate that. So, Dr. Kahl, you also mentioned treatments and how oftentimes it’s not a cancer where you can just remove the cancer. Can you talk about some of the exciting developments with treatments and new innovative therapies, and what are the most important highlights for patients and families?

Dr. Brad Kahl:

Yeah. There’s a lot to talk about here. So I’ll start with how we approach a newly diagnosed patient, and then we’ll go into how we approach patients who have relapsed disease. So the most often, or the most common way a follicular lymphoma patient comes to medical attention is they just either notice a lump from an enlarging lymph node, or some enlarged lymph nodes are just found incidentally because they’re having some testing for some other condition.

And so, like I said, very often patients don’t have symptoms. That’s very typical. Occasionally, the patients will have symptoms, and those symptoms might be pain from a large lymph node mass that’s pushing on something. Occasionally, they might have fevers or night sweats. They wake up in the middle of the night just drenching wet, or unexplained weight loss. Those would be symptoms that can occur in follicular lymphoma. But most patients who come to see us for the first time don’t have symptoms.

When we have a newly diagnosed patient and it takes a biopsy to make the diagnosis, we then need to do the staging evaluation. So that involves some sort of imaging. And nowadays that’s usually in the form of what’s called a PET scan, which gives us a good snapshot of the whole body. And it’ll show us enlarged lymph nodes. And then the PET portion of the scan will show us if the lymph nodes are metabolically more active.

So they show up as these bright spots on the PET scan. And that’s what allows us to stage the patient. It tells us where the disease is located and how much of the disease we see. And so I’m often telling patients, I don’t worry so much about the stage. I worry more about the disease burden. So the way I explain that to patient is, suppose I could take all the follicular lymphoma cells out of your body, and I made a pile. How big is the pile? And that’s actually, I think, more important than the stage in determining our initial strategy.

Because believe it or not, if we have a patient who comes to us with a new diagnosis of follicular lymphoma and they have no symptoms, and it turns out that their tumor burden is very low, we often will recommend an initial approach of no treatment, which is a strange thing for patients to hear. And we spend a lot of time trying to explain the rationale for that. So I’ll try to explain that to you now. Follicular lymphoma is hard to cure.

So it’s this weird cancer in that it’s slow-moving. It often doesn’t make people sick, and we have good treatments for it, but curing it, like making it go away once and for all, proves to be kind of difficult. And studies in the past have shown if you have a patient who has no symptoms and is low tumor burden, that their prognosis is just as good if you leave them alone at the beginning. And many patients will not need any treatment at all for two years, three years, five years. I even have follicular lymphoma patients who I’ve been observing for more than 10 years that have never needed any treatment.

About two out of every 10 patients that are newly diagnosed can go 10 years without needing any treatment. So that’s why we’ll start that strategy for some patients. And that’s psychologically can be difficult for patients. You’re telling me I’ve got a new cancer diagnosis. You’re saying you have good treatments for it. And yet you’re saying you don’t want to use any of those treatments. And so it takes a lot of talking and explaining to try to get people comfortable with that.

Some people never get comfortable with that, I admit it. But some people get very comfortable with it. But it is a very appropriate initial strategy for a low tumor burden asymptomatic person just to observe and get a handle on the pace of the disease. If the disease starts to grow, or if the patient starts to get symptoms, we can start our treatment at that time. And the treatment is going to work just as well as it would have had if we started it last year, or two years ago.

So we feel like we’re putting the patient in no harm, no risk of harm by starting on this strategy of a watch and wait. On the other hand, some patients have high tumor burden, they have a lot of disease, or they have symptoms. And for those patients we need to start them on treatment because the treatment can put them in remission and get them feeling better. Right now, the most common frontline treatment in follicular lymphoma will be a combination of some chemotherapy and some immunotherapy.

The most commonly used regimen in the United States right now is a two drug regimen, a chemotherapy drug called bendamustine (Treanda), and an immunotherapy drug called rituximab (Rituxan). And you give that treatment every 28 days for six months. And it’ll put 90 percent of people into remission. And on average, those remissions last five plus years. And it’s a very, very tolerable treatment.  It’s not too bad as far as chemotherapy goes. There’s no, most people don’t lose their hair. They don’t get peripheral neuropathy, that sometimes chemotherapy drugs give.

It’s not too bad for nausea and things like that. I’m not saying it’s easy or it’s fun. It’s none of that. But as far as chemo goes, it’s not too bad. And it’s effective, it is very effective. And I’ve given that treatment and I have people who are still in their first remission 10 years later, so you can get, for some people can get these really long remissions. But the reality is most patients, their disease does come back, they do relapse at some point. And then we have to start talking about what to do for second line treatment or third-line treatments.

And that’s where things have really taken off in follicular lymphoma in the last few years, there are a number of brand new treatment options in play for relapsed follicular lymphoma that are very exciting, and proves that we’re moving away from chemotherapy. We have drugs that are oral, that are, we call them targeted agents, they hit like a molecular pathway inside the cell a lot, and they kill the cells a lot differently than chemotherapy does. And we have a number of new drugs that work through the immune system, and try to attack the lymphoma that way.

So when we have patients who relapse, probably the most commonly used second-line treatment right now is a combination of a drug called lenalidomide (Revlimid), which is a pill that’s used in a few different cancers. It works very well for certain cancers, and it works well in follicular lymphoma. And that’s given with the immunotherapy drug called rituximab. And that was proven in a study to be very effective. About 80 percent of people will respond to the regimen, and that remission on average lasts in the two to three-year range.

So that’s probably the most commonly used second line regimen right now in the U.S. for follicular lymphoma. And then there are a number of treatments that are now available in third-line and beyond that are new within the past, say three, four years. And these newer treatments that I’m about to describe are now being tested as second line treatments and even as first-line treatments.

So it’s possible that some of these treatments I’m about to describe will become in the future, our go to regimens for first line treatment or second line treatment. And we hope they do move up, because that means they’re, it means they’re even better than what we’ve been using. So probably the treatments that we’re most excited about right now in follicular lymphoma are the drugs called bispecific monoclonal antibodies. There are two that are now FDA-approved. One’s called mosunetuzumab-axgb (Lunsumio), and that was approved about a year-and-a-half ago.

And the other one’s called epcoritamab-bysp (Epkinly), and that was approved just a month ago. And basically these drugs are infused or injected under the skin, infused intravenously injected under the skin and their proteins that will literally stick to the lymphoma cells. And when it does that, it kind of coats the cancer cells. And then after these bispecific antibodies coat the tumor cells, they literally will trick the patient’s T cells or healthy T cells to come in and attack the cancer.

So it’s a way of trying to trick the patient’s own immune system to come in and start fighting the cancer. And these two drugs are very promising in the relapse setting. They work about 80 percent of the time to get some kind of response. About 60 percent of the time patients will go into complete remission, which means we can’t find any evidence for the lymphoma on scans. And they’re both so new that I don’t think we have a full understanding of how durable these remissions are going to be right now.

It looks that like about, if you do get a complete remission, that about half of those patients are holding that complete remission at two and three years. But we’re, we don’t know about four years and five years yet because the drugs are too new. And we expect that if, as these drugs move up and are tested in the second-line setting and in the first-line setting, they’ll work even better because the cancer cells tend to be easier to kill in earlier lines of therapy. Other agents that have moved into the relapse follicular lymphoma space would include CAR T-cell therapy.

This is a fairly sophisticated complicated approach where you actually will run the patient’s blood through apheresis machine and you will extract the patient’s T cells and those T cells get genetically modified in a lab and then expanded and then are shipped back to the center and then re-infused back into the patient. So now again, we’re tricking the patient’s T cells into fighting their B-cell lymphoma.

And there are three CAR T products that are now FDA approved for use in follicular lymphoma, and they have very high response rates. With seemingly good durability we’re now getting three and four-year follow-up for these CAR T products with about half of people still in remission. The CAR T products probably have a little more toxicity and a little more risk than the bispecifics. So I think most of us are thinking we would try the bispecifics before CAR T, but there might be certain patients where a CAR T strategy is more appropriate to use before a bispecific.

So we’re very excited to have these tools in our toolbox. It’s always good to have more options. And then I should just mention the small molecule inhibitors. So here’s an example. Just this past year there was approval for a small molecule called zanubrutinib (Brukinsa). It targets an enzyme called BTK or Bruton’s tyrosine kinase. This is a pill really well tolerated. It’s given in a combination with an immunotherapy drug called obinutuzumab (Gazyva). This zanubrutinib-obinutuzumab combination got FDA-approved just this year for recurrent follicular lymphoma.

The results look very good for that. It’s very well-tolerated. There’s another oral agent called tazemetostat (Tazverik), which was approved a couple of years ago. It targets a mutated protein in follicular lymphoma. This is, again, is a pill super well-tolerated, very few side effects. So, there’s just a few examples for you of all the different treatment options we have for follicular lymphoma that has recurred after initial treatment.

And believe it or not, the decision-making can be difficult when you have so many choices and so many good choices, that’s a good problem to have. And I find myself a lot of times spending a lot of time with the patient and their family as we talk through these different options, and we try to think what’s best for them at this point in time, talking through the pros and the cons, how active it is, what side effects do we need to be concerned about. And it’s a lot for patients to digest when you have so many choices. But like I mentioned that’s actually a good problem to have.

Lisa Hatfield:

I think you’re right. There’s a lot of hope in those options. I do have two follow-up questions. One of them is when you talk about lenalidomide or brand name Revlimid, CAR T bispecific antibodies, this new small molecule, are these all quality of life is so important for cancer patients. Are these all limited duration treatments for recurrent disease when there’s a recurrence of the disease or are they long-term treatments for the disease?

Dr. Brad Kahl:

Yeah, really good question. And the answer is different for every agent. So I’ll try to just kind of run through the list. For the CAR T products, the three different CAR T products, it’s like a one-time treatment and then you’re done because the cells that get infused will persist in the patient’s body for months and months and months. So they’re infused and then the cells will hang around a long time acting on the cancer. So for the CAR T it’s a one-time treatment. For the bispecifics, the mosunetuzumab-axgb product is a time-limited treatment that is done in less than a year. The epcoritamab-bysp is designed to be given indefinitely.

So those are, there are some pros and cons of those two agents, the two small molecules that I mentioned, the zanubrutinib is meant to be given indefinitely and the tazemetostat is meant to be given indefinitely. And then the first one I mentioned was the lenalidomide. That is in follicular lymphoma that it was developed to be given for 12 months in this setting. So the duration of therapy is unique for each of the different agents that I mentioned.

Lisa Hatfield:

Okay. Thank you for that overview of all those emerging therapies. That’s great to know for patients, Dr. Kahl. 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, our disease, and our prognosis. Please remember, however, this program is not a substitute for medical care. Always consult with your own medical team.

So, Dr. Kahl, we have several patients who have submitted some questions. The first question is regarding emerging technologies. And I think that you probably have answered that very well actually in a discussion here. So the second question this patient had is how might future innovations build on the latest treatments to offer even better outcomes for patients? You, I think maybe have touched on that, but maybe speak to that a little bit more as far as longer remissions. Yeah.

Dr. Brad Kahl:

Right, right. So I think right now the main emphasis in research is to take some of these really promising drugs that were developed for relapsed follicular lymphoma and do two things with them, test them in combinations in the relapse setting to see if you can make them even more active. So an example of that would be take the drug lenalidomide, which is really active in the relapse setting and pair it with the drug mosunetuzumab-axgb, which is very active in the relapse setting, and pair them together and see if you can get better results than either drug alone.

So there are studies trying to answer questions like that at this time. And then the other area of major interest is to take these promising new treatments approved in the relapse setting and test them upfront. So there are studies being literally designed right now as we speak that will test bispecific monoclonal antibodies in the frontline setting.

So patients can envision being offered a chance to have a chemo-free strategy where they’re just getting a bispecific monoclonal antibody as their initial treatment. And there are studies that will test these drugs as single agents, and there are studies that will test these drugs in combinations with other agents in the frontline setting, like lenalidomide, for example. So we have no results from any of these trials yet, but these trials are just starting to enroll patients and this could fundamentally change the way we’re managing follicular lymphoma in the future if any of these new strategies turn out to be more promising than what we have done historically.

Lisa Hatfield:

Thank you. Okay. Another question, Dr. Kahl. How do outcomes differ for patients with relapsed/refractory disease compared to those who respond well to initial treatment?

Dr. Brad Kahl:

So that’s a really good question. And when we have a patient going through frontline treatment, we’re all really crossing our fingers that that first remission is incredibly durable. Because when the disease relapses, the remissions do tend to get shorter and shorter and shorter, which is frustrating for everybody.And so we love it when we get a nice long first remission. And in the older days when all we had to offer was chemotherapy and some different immunochemotherapy regimens, the remissions in second line and third line might be two years or one year.  It can get frustrating as you go through treatment after treatment after treatment. It’s hard on patients. The side effects start to accumulate. And that’s one of the reasons we’re so excited about all these new agents that we have for relapsed disease with the bispecifics and the CAR T products and the small molecule inhibitors like tazemetostat and zanubrutinib. Because it appears as though these remissions for relapsed disease might be getting longer than what we have seen historically. So there’s no question that dealing with relapsed follicular lymphoma is more difficult than dealing with frontline follicular lymphoma. But we’re optimistic that these newer treatments we have are improving outcomes for patients with relapsed disease.

Lisa Hatfield:

Okay. Thank you. And another question, which patients are considered the most vulnerable when it comes to follicular lymphoma and why, and what measures can be taken to better support these populations in terms of treatment and care? And I’m not sure if they’re talking about different age groups or ethnic groups or geographic groups like rural versus more urban areas, but if you can speak maybe to general terms to answer that question, that would be great.

Dr. Brad Kahl:

Yeah, right. Well, the first thing that comes to mind are older patients. Older patients are always more challenging to take through cancer therapies. The older patients are more fragile. They don’t tolerate the treatments quite as well. They don’t have the physiologic reserve. They’re more susceptible to complications and infections. So I always think when we have older patients that need treatment in follicular lymphoma, the doctor has to be extra, extra careful, sort of the Goldilocks principle. You don’t want the treatment too hot and you don’t want it too cold, too hot, it might work great, but you might get unacceptable side effects too cold, maybe no side effects, but not enough activity against the disease. So we’re always trying to get that patient the best remission we can get them, but doing the least amount of harm along the way.

So I think that takes a little bit of art, a little bit of experience to figure out how to get your older more fragile patients through follicular lymphoma therapy. And then I think the whole idea of patients who live in rural areas, that can often be challenging too, because they may be hours and hours away from medical care. So if they do have a complication of treatment, an infection, for example, it can be challenging to get them the care they need in a quick amount of time. So when I have patients who I know live way out in the country, far away from our center, I just, we always give them a card, it’s got our phone number and I’m like, you feel like something’s going wrong, call us. I don’t care if it’s 2 in the morning, you call us.

It’s not your job to figure out what’s going wrong. That’s our job. It’s just your job to describe to us what you’re experiencing and then we’ll figure out over the phone whether we want you to drive the three hours to come see us or whether we think you just need to go to the closest place, which might be 30 minutes away. So at least you’re in the hands of some medical professionals. And then they can call us with an update on what they’re noticing, what the tests are saying. So taking care of patients who live far away from the medical center poses some additional challenges.

Lisa Hatfield:

Okay. Thank you. And that’s a great takeaway for patients. If you have a question, call your provider. They can help take the stress away from making that decision yourself. 

Well, here’s a loaded question for you, Dr. Kahl. Why does relapse happen in the first place, and what are the changes in the body that signal when and if treatment is likely going to fail?

Dr. Brad Kahl:

Boy, we wish we understood why relapse happens in the first place. Last I mentioned, most of these treatments can get people into remission, which means that they can kill the vast majority of the cancer cells, maybe 99.9 percent of them, but for some patients, there’s just a few stubborn cells that remain behind. Maybe those cells are just sitting there, not growing at all, which follicular lymphoma cells can do.

And when the cells are not trying to divide, not trying to grow, they’re kind of protected from killing. They’re just sitting there doing nothing. And so we think it’s this property that how the cells kind of protect themselves. And so these rare cells that are just kind of sitting there, quiescently not growing, not dividing, these might be the cells then that just hang around for years and then contribute to that relapse five years down the road.

But I admit we don’t fully understand why one patient will relapse two years after a treatment and the next patient is still in remission 10 years later. These are things that we don’t fully understand. Every patient’s lymphoma is a little different, I’m afraid. So two people with follicular lymphoma, they don’t really have the same cancer, cancer, they are sort of like snowflakes. No two are alike. And so they can have different mutations inside the cells that’ll make the cancer behave a little differently from one patient to another. It might make it respond to treatment a little differently from one patient to another. And so what is true for one follicular lymphoma patient may not be true for another.

So if a patient’s symptoms are not being relieved, that might be a clue that the treatment isn’t working as well as we want it to. And then in some cases the only way to figure out if a treatment is working is by scanning. So we’ll have a before picture from a PET scan or a CT scan, and then we’ll take them through a few cycles of treatment, and then we’ll get another scan to prove that the treatment is working like we want it to work. And if it’s not working like we want it to work, then we’ll say, okay, this one isn’t working for you. Let’s go to the what we think is the next best option for you.

Lisa Hatfield:

Okay. Thank you. And just listening to you and hearing about all these nuances with follicular lymphoma, I would probably recommend as a patient myself with a different kind of cancer, seeking out at least a consult from somebody who specializes mostly in follicular lymphoma, at least a hematologist who can tease through some of these nuances to help you as a patient find the best treatments and therapies and quality of life. So just a little tidbit there. So, Dr. Kahl, 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. And on behalf of patients like myself and those watching, thank you for joining us, Dr. Kahl.

Dr. Brad Kahl:

Thank you for having me.

Addressing Practice Gaps in CLL Therapy: Overcoming Barriers and Enhancing Patient Care

Transcript:

Dr. Nicole Rochester:

Well, let’s move into talking about side effects. And you all have already alluded to the importance of dose modification with regard to side effects and minimizing toxicity. So I’m going to go to you, Dr. Ermann. What techniques do you use in your practice for optimizing treatment efficacy while minimizing toxicity?  And feel free, if you’d like, to share a specific example.

Dr. Daniel Ermann:

Yeah. Great question. So in CLL, there are a lot of unique toxicities with our CLL-directed therapies. I’ll take, for example, BTK inhibitors. So BTK inhibitors have certain off-target effects. The way these medications work is they turn off BTK, and that’s like flipping a switch that decreases the growth of the CLL cells and eventually causes them to die. However, some of the unique toxicities we see are things like atrial fibrillation, bleeding, bruising, infections, to name a few.

So, for example, you would like to start a patient optimally on the maximum dose, which is the kind of recommended starting dose. However, let’s say a patient gets a side effect such as bleeding or atrial fibrillation, I usually will follow the package insert pretty closely. In most cases, the recommended management is to hold the drug until a side effect resolves and then resume at the same dose. In my practice, I found that with many of our novel therapies, there are some cases where you can continue the same dose, but oftentimes you’ll need to dose-reduce.

And I will say from my personal experience, I think dose reduction can make a big difference in the side effect profiles of these medications. I’ve seen reduced bleeding, for example, reduced rates of atrial fibrillation. With BCL-2 inhibitors, I’ve seen reduced rates of neutropenia, for example. And I’ll just say from my experience, I haven’t seen too much compromise in efficacy. So I think I would recommend for providers when you’re thinking about dose reduction, it’s really a balance of toxicity and efficacy. And I think with just how good our treatments are for CLL these days, I try to reduce toxicity. And I think in that way, it does maximize their efficacy.

Dr. Nicole Rochester:

Thank you, Dr. Ermann. What about you, Dr. Chang? How do you approach dose adjustments for CLL patients, particularly those who may be experiencing severe side effects? And what factors influence your decision-making process?

Dr. Andres Chang:

Yeah, so first of all, I agree with Dr. Ermann that I think trying to mitigate side effects and oftentimes following the package insert is really, really helpful. One of the things that I want to add, though, is I do spend quite a bit of time before starting any medication, educating patients and trying to teach them about what potential side effects, what to look for. And importantly, if there are mechanisms to mitigate or prevent those side effects, I will spend quite a bit of time talking about that. And these can be things such as taking caffeine to prevent an acalabrutinib-induced (Calquence) headaches, for example, maintaining adequate fluid intake and hydration to minimize the risk of tumor lysis, and so forth.

I find that by spending that time with patients ahead of starting therapy, that oftentimes it allows patients to identify the side effect and also start addressing it even before needing to come back to the clinic. My team, in addition to myself, also spends quite a bit of time, and we perform phone calls, follow-up phone calls, and things like that, that are conducted by my pharmacist or by my nurse. And together, I find that oftentimes just by talking through these potential issues, patients will feel a lot better.

Now, depending on how severe an adverse event is, or a side effect is, I tend to potentially dose-reduce somewhat quicker. Or if there’s an alternative, like in the case of BTK inhibitors, I will be a little bit more prone to switching from one BTK inhibitor to another, because there is data suggesting that if you don’t tolerate one BTK inhibitor, you can tolerate a second one. And that’s particularly true if we are seeing some of these side effects that arise in the long term, particularly with ibrutinib (Imbruvica), and switching them to acalabrutinib or zanubrutinib  (Brukinsa), oftentimes resolve those kinds of side effects. And I’ve seen that particularly true in cases where I see hypertension induced by ibrutinib (Imbruvica). I have a couple of patients where they are four or five years into ibrutinib therapy, came in with uncontrolled hypertension, I switched them to another BTK inhibitor, and the hypertension gets better controlled.

Dr. Nicole Rochester:

So now we’re going to shift to talking about clinical trials and novel targets focused on molecularly defined patient subgroups. We know that by understanding the molecular profile of a patient’s CLL, that oncologists can choose the most effective therapies. So, Dr. Brown, I’m going to start with you for this one. Can you talk about any emerging CLL trials targeting specific molecular subgroups, and also how can CLL experts stay updated on these advancements in clinical trials?

Dr. Jennifer Brown:

So, as you heard from Dr. Coombs, there’s increasing interest in looking at high-risk patients in particular, and I think looking specifically at patients with p53 aberration in dedicated clinical trials, it’s become increasingly clear that the behavior of the disease when it’s higher risk based on p53 mutation, NOTCH mutation, IGHV status is quite different, particularly with time limited therapy compared to lower risk disease. And so having dedicated trials that evaluate outcomes specifically in certain of these subgroups is increasingly important. We do have more trials than we used to focusing specifically on p53 aberration.

My personal belief is that we would be well served to have trials separately in the IGHV groups that Dr. Coombs mentioned, although that has not gained as much traction. And then what we are seeing is now that there are resistance mutations, it actually has turned out that some of the drugs that we use in that setting, venetoclax (Venclexa) and pirtobrutinib (Jaypirca), seem to have pretty similar activity in patients with and without the mutations. But as drugs are being studied in this context, there’s been an increasing tendency to study them in specific subgroups.

So patients who have the mutation and had clinical progression on a covalent inhibitor, patients who don’t have the mutation and had clinical progression, patients who may have come off their covalent inhibitor for adverse events who may not actually be resistant, what is their response to the next line of therapy? And so all of that is just helping us understand in a more nuanced way what the best benefit for patients will be as we look at these different subgroups of patients.

Dr. Nicole Rochester:

Thank you, Dr. Brown. Appreciate that. Dr. Coombs, do you have anything to add?

Dr. Callie Coombs:

Yeah, so I echo all of Dr. Brown’s comments, and I think I’m the person that is bringing all the practical aspects of CLL care because it’s, she’s so thorough. I just always like to contribute a few little pearls. So, pirtobrutinib has been an exciting drug, to see it become available for our double refractory patients. So the current FDA indication is for patients failed by not only a covalent BTKi but also venetoclax. But it’s the first BTK inhibitor that we can effectively use in the setting of a prior BTK inhibitor.

And that’s because of this unique aspect where instead of forming a covalent bond at the C481 residue, it binds reversibly, and we can still see activity. But the practical aspect is that that’s not an effective strategy when you have a patient progressing on, say, ibrutinib (Imbruvica), you can’t switch them to acalabrutinib (Calquence) or zanubrutinib (Brukinsa) because of their shared mechanism of resistance. They’re all covalent inhibitors. They all share the same mechanism of resistance.

And so that’s one thing I’d like to bring up. However, there’s a very different and very common clinical situation that I encounter really a lot in my clinic, which is intolerance. And so that’s where it would be a very effective strategy to switch a patient from one covalent drug to another. And so literally in the past couple weeks of clinic, I’ve had patients with chronic long-standing toxicities to ibrutinib (Imbruvica) that perhaps went underrecognized where I say, “Hey, you’ve had…notice your blood pressure has gone up a lot.

Let’s switch you over to acalabrutinib,” or other patients, “Oh, you’ve had issues with atrial fibrillation, it…let’s try switching you to zanubrutinib.” Because the rates are a lot lower and a lot of patients can have improvement or just complete resolution of the prior side effect. And so I hope that that emphasizes this is something that we think about every day, and switching is appropriate in the setting of intolerance. It’s not appropriate when you’re staying in the covalent class to switch in the setting of progression. But pirtobrutinib being a non-covalent inhibitor is certainly very effective after a covalent. And I think once we see readout of some of the ongoing Phase III trials, we may be able to use it in that setting under an approved FDA label, though that is to be seen in the future.

Managing CLL Side Effects | Innovative Strategies and Approaches

Transcript:

Dr. Nicole Rochester:

Dr. Brown, how do CLL healthcare providers better understand mutation profiles including the emergence of novel CLL mutations over time?

Dr. Jennifer Brown:

Well, the first thing that’s important to recognize is that CLL is not defined by any particular mutation. The landscape is quite varied and we see a large number of different mutations at low percentages. Well, the second key point to remember is that there are different mutations at baseline and then there can be acquired mutations that include some of what we see at baseline, but also novel resistance mutations that we don’t ever see at base.

So at baseline, the most common mutations, which are somewhere in the 10 to 20 percent range of patients, although less than that if you have very early stage patients, affect the p53 gene, NOTCH1, SF3B1, and ATM. P53 is the most important because that one does influence our thinking about the patients and our choice of therapy in some cases. P53 can be altered in CLL in two different ways. Actually, the most common way is as a deletion, deletion of the short arm of chromosome 17 or 17P deletion. About 75 to 80 percent of patients that have that deletion will have a point mutation usually in the other p53 allele. So they have double knockout of p53.

A small percentage of people with the deletion will not have the mutation. And then a certain number of patients will have just the mutation without the deletion. And one of the things that I’ve been very interested in for a while that we’re still trying to understand better is the implications of these different combinations of the way p53 can be affected in people with CLL, and that it may, in fact, be more adverse to have both alleles knocked out than single, although we don’t have great data for that as yet because most of the data that we have has combined all of it together.

But it’s very important to test for the p53 mutation alone because even if patients have only that one, at present, we consider the treatment implications of it all similarly regardless of how the p53 gene is affected. And then NOTCH1 is a fairly common mutation that always worries us a lot, because it’s associated with Richter’s transformation, which is a very high-risk event, but we don’t know anything to do about that to try and prevent it or to alter our therapy based on it.

So at the moment it’s mostly something that we are aware of that we keep an eye on but not that changes therapy. And SF3B1, ATM, and this long list of other genes that can be mutated in just a few percent of CLL, and mostly what we know about them is some biology that’s been studied, and then the fact that the more of these mutations are mutated in a patient that is associated with a worse prognosis, just a total number.

But that’s not something also that really alters our therapy. And then when patients go through lines of therapy, they can sometimes acquire mutations in these genes. So a patient can acquire a mutation in p53 or in NOTCH after their second or third line of therapy. But the mutations that are hottest right now, or that people are most interested in are some of the mutations that occur as resistance to therapy.

So in particular, that means BTK mutations. Covalent BTK inhibitors have transformed the therapy of CLL, and they bind to the cysteine 481 residue of BTK. So that means, as you might imagine, that if you mutate that cysteine so that the inhibitor can’t bind, that will be associated with resistance. And that, in fact, is what has been found that the cysteine to serine mutation at 481 is the most common resistance mutation in patients on covalent BTK inhibitors.

And in the case of ibrutinib (Imbruvica), it makes the inhibitor into a much weaker and non-covalent inhibitor. In the case of acalabrutinib (Calquence) and zanubrutinib (Brukinsa), it probably abrogates all activity. And so that’s a mutation that we will sometimes look for in patients with clinical progression on those drugs. There’s also a mutation in BCL2 that can occur in patients in venetoclax (Venclexta).

So another example of an on target resistance mutation. The role of that one is a little bit less clear, and testing for it is not as widely available, but we’re still working on that. Resistance to venetoclax is probably more complicated than resistance to BTK inhibitors, although there’s also a subset of patients who will get BTK inhibitors who have novel mechanisms of resistance not related to BTK that we don’t really know anything about as yet.

And then finally, the non-covalent BTK inhibitors are becoming available, pirtobrutinib (Jaypirca) was approved for CLL in the United States in December for patients who’ve had covalent BTK inhibitors and venetoclax. And we’re starting to see different mutations in BTK at different sites, even though pirtobrutinib has activity against the 481 mutation. So there’s going to be a lot of activity in this area in the next few years probably.

Dr. Nicole Rochester:

Thank you so much Dr. Brown, that was a very comprehensive overview of the mutations. Dr. Coombs, do you have anything that you want to add to what Dr. Brown said perhaps specifically around mutations associated with the progression of CLL?

Dr. Callie Coombs:

Sure. So, that’s a hard act to follow. She really took us through a whirlwind of everything mutation-related. I think what I would like to focus on in my answer is, well, what should we be testing for on a day-to-day basis in our CLL practices and what are some common misconceptions? So specific to TP53, I would say this is the most important test as far as all of the genetic tests that influences what we do day to day in the care of patients with CLL. 

I test for this for my newly diagnosed patients who I think may be interested in enrolling in a clinical trial, first of all, so the standard of care in CLL is watch and wait, however, patients with higher risk disease may be eligible for trials looking at early intervention specifically the SWOG EVOLVE trial looking at early treatment. And so that’s one of the risk markers that can get a patient into the higher risk category of CLL where they could be eligible for a trial.

A common misconception I see is that 17p is the same thing as a TP53 mutation, it’s definitely not. So these are two different tests that have to be sent. 17p can be picked up on karyotype testing and on FISH testing where it looks for 17p deletion. However, mutations are a different test. And so I usually send a next gen sequencing assay that includes other genes.

However, you can test purely just for mutations in the TP53 gene, but again, that’s a sequencing test, so I’d like to convey that, somewhat a misunderstanding, but it’s such an important gene in CLL because when patients have TP53 aberrations, whether that’s 17P or a  TP53 mutation or both, given that they can occur in isolation or together, these patients should never get chemotherapy, because they have extremely terrible responses to chemo, and that should not be part of the therapies offered to these patients.

The other interesting, I’d say controversial at least in 2024, is what is the role for mutation testing in the clinic in the setting of acquired resistance to inhibitors? So I think it’s very clearly important in the research setting where I think learning about the C481 mutation among others in the setting of covalent BTK inhibitors has shown us a lot about mechanism of resistance. But in the clinic, I don’t necessarily think that’s something that needs to be universally applied, given that it most of the time doesn’t affect what we would do clinically. And so one example is a patient comes in progressing on ibrutinib, maybe about two-thirds of them may have a mutation in the C481S. However, if they’re clinically progressing, they need to switch therapy.

Start Here: Bridging the CLL Expert and CLL Patient Voice

Chronic lymphocytic leukemia (CLL) can sometimes feel overwhelming and complicated, but what can patients and care partners do to help improve their care? With this question in mind, the Patient Empowerment Network initiated the START HERE CLL program, which aims to close the gap in the expert and patient voice to build empowerment. 

START HERE CLL Program Resources

 The program series includes the following resources:

Lisa Hatfield and Dr. Danielle Brander

Patient-Expert Q&A Webinar Topics and Key Takeaways

In the Patient-Expert Q&A webinars, CLL experts Dr. Ryan Jacobs from Levine Cancer Institute, and Dr. Danielle Brander from Duke Cancer Institute shared their expert knowledge to help patients and care partners fortify their knowledge and confidence. The webinars provided some in-depth discussion along with key takeaways derived from questions submitted by patients. Some of the discussion covered:

Among some key points from the webinars, Lisa and Dr. Jacobs discussed the importance of genetic markers. Dr. Jacobs recommended CLL patients ask their doctor about their prognostic markers. “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.”

The watch-and-wait phase of CLL, also called active surveillance, is a common term heard by CLL patients. However, there are actually two types of CLL. “While some CLL patients experience very gradual disease progression and are actively monitored during a watch-and-wait phase, other patients may experience a more expedited CLL progression and will need more frequent treatment.”

Treatment advancements for CLL have been moving forward over recent years. Dr. Brander shared her perspective about the advancements. “So over the last decade or even the last five years, for patients diagnosed with CLL, there’s been a very encouraging and marked change in the available treatments…not that many years ago we generally only had chemotherapy or chemotherapy combined with these antibody targeted treatments that we call immunotherapy sometimes. But in the last 5 to 10 years we’ve seen quite a remarkable change in treatments that target, meaning often they go after pathways or ways that the CLL cells have learned to grow or have learned to not die the way that normal cells should, die after certain time points.” 

Vaccines for those with CLL have gathered more visibility in recent years with COVID-19. Dr. Jacobs addressed some questions about vaccination and shared, “I in general am recommending, as does the CDC, to get boosted every six months for patients with any level of immune suppression and having CLL qualifies you as that. And then I recommend all of the general vaccines that come with age, like, for example, the Shingrix vaccine for shingles is now safe to give to CLL patients because it’s a conjugate vaccine, it’s not a live virus vaccine. So we’re lucky now with just standard vaccines in the U.S., there are no live virus vaccines that the CLL patient has to worry about anymore, so I definitely encourage shingles, pneumonia vaccines, boosting for COVID. We’ll see if we get an RSV vaccine, that sounds like it’s on the horizon. Flu, of course.”

Worries about CLL progression are felt by many patients, and there are some ways to stay alert for warning signs. Expert Dr. Jacobs explained signs of CLL progression including new or worsened drenching night sweats, significant changes in a patient’s ability to function, and major changes in lymph nodes over a short period. Dr. Jacobs also shared some research updates for treatments that have shown success against progression to Richter’s transformation. “…I’ve been having some recent success using CAR T in those patients, and also now have a, I was thankfully getting it sort of off-label approval to do that, but now I actually have a clinical trial investigating axicabtagene ciloleucel (Yescarta) in those patients.

Some CLL patients wonder about whether they can take a break from treatment. Dr. Brander addressed this question about BTK inhibitors. “…BTK inhibitors are given continuously, meaning, at least so far, the standard way we recommend of those treatments is that they’re taken every day, either once or twice a day, depending on which BTK inhibitor, and they’re taken every day. Unless patients run into progression, meaning the CLL learns to grow through its resistance or patients run into side effects that despite maybe team’s recommendation of changing the dose or holding the medications, that it’s just the medication is just not tolerate.”

Many CLL patients also wonder about the impact of exercise on their treatment response and their duration of treatment response. Dr. Brander explained about the impact of exercise. “I think certainly trials or studies really need to be continuing to look at this, because I think there likely are things that we can be more specific to patients about. There are studies looking at physical fitness and exercise regimens not necessarily specific to CLL, although there are studies being done in that space, but to other cancers showing that physical activity and exercise can help even for patients not on treatment maintain control of their cancer. So general daily activity and exercise are important in studies that look at how do you tailor that to an individual I think are important too.

Whether patient fatigue is originating from CLL or from symptoms of old age can sometimes be difficult to determine. Dr. Jacobs shared some insight about fatigue. “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.

Empowering CLL Patients for Treatment and Survivorship


Transcript:

Lisa Hatfield:

We have a couple of questions about BTK inhibitors, and you already talked a little bit about the role of those and why they’re significant in treating CLL. But another patient’s asking about the, of course, a lot of patients wonder, what are the side effects? They hear chemo and like, “Oh, my gosh, the side effects are going to be off.” Can you talk about the side effects and even maybe some unusual side effects that you’ve heard of from patients when using the BTK inhibitors?

Dr. Danielle Brander:

Sure, absolutely. And so again, really important, these are things that as we maybe anticipate patients are going to start treatment, this is a long discussion of deciding between treatment, for example, as first treatment. There’s no trial saying one path is necessarily better than the other. So we try to individualize choosing between BTK inhibitors or that venetoclax-based therapy I mentioned. Some of that though comes about and what expected side effects are expected side effects for the individual. I try for patients to hear it from myself, other members of the team, the nurse, our pharmacist, for example.

And so patients shouldn’t feel overwhelmed to keep asking about what to expect or new side effects. There are some side effects we talk about regardless of the treatment. So I’ll just point out, anytime you’re starting treatment, you’ll hear the team talk about risk for infection, monitoring for fevers, reaching out to us about those kinds of side effects, lower blood counts that can happen regardless, not specific to BTK though it can happen there as well.

There’s some specifically though with BTK inhibitors, we ask patients to watch out for. Some BTK inhibitors can cause some cardiovascular side effects, meaning watching out for funny beating of the heart or what we call palpitations, skipped beats. There can be arrhythmias, some patients can have with time elevation in their blood pressure, for example. And then risk for bleeding, meaning BTK inhibitors affect how the platelets stick together similar to what aspirin does.

So the platelet levels may be normal but patients might have easier bruising, just generally manageable. But if there’s any kind of bleeding, certainly the team should be aware. It’s also the reason though, if you’re on a BTK inhibitor and you have a planned surgery or procedure, let your team know, because we may recommend or a lot of times recommend holding the medication before and after certain surgeries or procedures.

Other side effects can be muscle or joint aches. Some patients have some gastrointestinal side effects like looser stools or sensitivities to certain food causing looser stools, for example. And then there are some that are specific to the individual BTK inhibitor. This is the one point I’ll mention that first-generation BTK inhibitor ibrutinib, part of the reason for the second-generation zanubrutinib (Brukinsa) and acalabrutinib (Calquence) is not necessarily of them working better but to have less of these side effects that I just mentioned.

Lisa Hatfield:

Can you talk a little bit about the novel pathways and targets that are currently under investigation in CLL, and what are the most important highlights from those for patients and their families and care partners?

Dr. Danielle Brander:

Yes. So over the last decade or even the last five years, for patients diagnosed with CLL, there’s been a very encouraging and market change in the available treatments that is, you know, not that many years ago we generally only had chemotherapy or chemotherapy combined with these antibody targeted treatments that we call immunotherapy sometimes.

But in the last 5 to 10 years we’ve seen quite a remarkable change in treatments that target, meaning often they go after pathways or ways that the CLL cells have learned to grow or have learned to not die the way that normal cells should, die after certain time points. The two main categories of treatments that are approved for CLL treatment, either for patients as a first treatment or patients that have had treatment before including prior chemo or other agents are called BTK inhibitors or BCL-2 inhibitors.

BTK is something inside the leukemia cells. It’s also in some of our other cells. But in the CLL cells particularly, they’re very sensitive in needing that protein. So in targeting that BTK inhibitors keep the cells from getting the normal signals that they need to stay alive, and so the lymph nodes that are big get smaller, a spleen that might be big get smaller, white count eventually comes back down, for example.

And those BTK inhibitors have also already encouragingly changed over recent years. So there was…you’ll hear people say first generation, these were the first inhibitors that came out, that was a drug called ibrutinib (Imbruvica), which is still around. And then there are second generation that are approved that have come out as first treatment or treatment for previously patients that receive treatment.

Those second-generation BTK inhibitors are called zanubrutinib (Brukinsa) and acalabrutinib (Calquence) that are approved. The main other approved category of these targeted treatments I mentioned is venetoclax based treatment. And that targets something different, that targets a set of proteins inside the cell that tell the cell to stay alive too long. And so you have this accumulation and venetoclax targets that pathway. And the last thing I’ll mention about the BTK inhibitors that’s emerging is now there are trials of what are called non-covalent BTK inhibitors.

So they work in a different way, they go after BTK and so that they can work. The non-covalent, even for patients where the first and second-generation, traditional covalent BTK inhibitors I mentioned stop working, those are not yet approved officially for CLL, though they’re approved in mantle cell lymphoma. That’s a drug called pirtobrutinib (Jaypirca), that’s a non-covalent BTK. And the reason that emerging set of treatment, as I mentioned, is important is because it can work for patients where the first or second-generation covalent BTK inhibitors stop working. The venetoclax (Venclexta), as I mentioned, works by a different mechanism. So patients, of course, where the BTK stopped working, in many cases venetoclax can be helpful as well.

Lisa Hatfield:

So I read a little bit, I did a little research on trials that you’re involved in, and there is a trial the EVOLVE CLL trial, and I wonder if you can talk about that a little bit because I think it is exciting for patients to hear that there might be an option for earlier intervention. And I’m not sure if you’re allowed to talk about any results yet, but if you can speak to results, that would be great to hear about those results too.

Dr. Danielle Brander:

Well, yes and no, thank you for bringing this up because this is very important. As you mentioned, it’s called the EVOLVE study. It’s led by a national cooperative group called SWOG, meaning there are lots of places that it’s available, not just larger centers, but smaller oncology centers as well. And this is to look at what’s called early intervention, meaning as we spoke about before, most patients with CLL don’t need treatment at the time that they’re diagnosed.

The reasons for treatment are, we call those treatment indications are based on three main categories that I’ll just review. For some patients, it’s new or progressive symptoms like weight loss or, very symptomatic limiting life day-to-day activities like night sweats or fatigue, for example, that’s the first category of reasons some patients might need treatment is unmanageable side effects.

The second main category is if the lymph nodes get very large or impacting on organ function, or the same for the spleen, it’s getting very large to a certain size, or it’s affecting your ability to eat regular meals or losing weight. And then the last category of treatment indications that we generally wait to start treatment for are if it’s affecting the normal blood count.

So there’s not one magic white count where patients need to start treatment, but almost like weeds in a garden,  if those CLL cells are crowding out the red blood cells, so the hemoglobin’s falling or it’s crowding out the platelets, so the platelets are crowding and can’t grow and reach a certain threshold, then we recommend treatment. Of course, there are scattered other reasons, but those are the main three categories. And the reason of waiting to start until those are met is because historically trials have been done to look at waiting for those indications versus treating around the time of diagnosis.

Those trials so far have included, chemotherapy by itself or chemotherapy in combination. And most recently there was a trial looking at first-generation ibrutinib that was given continuously. And so far there’s been no survival. So no life expectancy benefit to early treatment versus waiting for those indications. And the other reason generally not treating all patients is because some patients never require treatment, about a quarter of patients.

So if we offer treatment to everybody, at the time of diagnosis, there are patients that would get treatment that would be exposed to side effects and never needed. But what the EVOLVE study is uniquely looking at is randomizing. And randomizing means some patients will get treatment and some patients will wait until those traditional reasons to need treatment. But for those randomized to receive therapy, it’s that venetoclax based treatment combined with this antibody called obinutuzumab (Gazyva).

And the way that treatment is given for patients, is the same way it’s given for patients who outside of the trial need treatment, meaning they get the antibody infusion, then they get the venetoclax pill, but it’s for a fixed duration, meaning a total of one year of treatment. The trial is also only for patients with higher-risk CLL. So as I mentioned, some patients never need treatment, some patients do, some patients need it quicker.

So rather than looking at this trial and saying all patients, including those with CLL, that’s likely to be slower-growing. The EVOLVE trial is only for patients who are more likely to need treatment in the next couple of years.  And the way that’s determined is a score called the CLL-IPI score, and CLL-IPI tries to identify patients more likely to need treatment in the next couple of years by a couple of key factors.

Stage at the time of diagnosis, it looks at age, and it looks at key factors of the leukemia itself, including something called deletion 17P or TP53, because that marker in the cells is a high risk of eventually needing treatment.  So to answer your question, what EVOLVE is looking at is taking higher-risk patients, so patients rather than all patients more likely to need treatment anyway, and around the time of diagnosis, randomizing to either be treated or to follow the traditional, sometimes called watch and wait or dynamic monitoring until they reach traditional markers. And ultimately, and it’ll likely take many years to look at, ultimately the question is looking at if that helps prolong patient survival by having higher-risk patients receive that fixed-duration treatment earlier in time. We don’t yet have any results or any results to share, because the study is still enrolling.

Dr. Danielle Brander:

But again, I think it’s something for patients to be aware of, because it does look at the higher risk patients. But around a year, it has to be within a year of diagnosis. So patients who are newly diagnosed, the question to ask your oncology team is “Do I qualify?” if it’s something you’re interested for, and they’ll help walk you through that. If you haven’t had markers checked, for example, it might be a good time to ask about that, to see if this is something would be available, even if not available though, it does create a time to talk to your team about the markers, because those can inform regardless of trial or not maybe what to expect in coming years and likelihood of treatment.

Lisa Hatfield:

Welcome to this START HERE, Patient Empowerment Network program. This program bridges the CLL expert and patient voices, enabling patients and care partners to feel comfortable asking questions of their healthcare team. Joining me is Dr. Danielle Brander, a CLL specialist serving as assistant professor in the Division of Hematologic Malignancies and Cellular Therapy at Duke University Medical Center. Dr. Brander directs the chronic lymphocytic leukemia or CLL and lymphoma program and serves as primary investigator for CLL focus clinical trials. Thank you so much for joining us, Dr. Brander.

Dr. Danielle Brander:

Thanks for having me, Lisa.

Lisa Hatfield:

The world can be complicated, but understanding your chronic lymphocytic leukemia diagnosis and treatment options doesn’t have to be. The goal of START HERE is to create actionable pathways for getting the most out of CLL treatment and survivorship. 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. So let’s get started. Dr. Brander, I’d like to talk about what’s on the CLL treatment radar. There’s a lot going on in terms of emerging treatment options, clinical trial data, and other learnings from the CLL community. Before we jump into a detailed discussion, can you provide an explanation of what CLL is?

Dr. Danielle Brander:

Absolutely. So CLL, or chronic lymphocytic leukemia, we generally think of as blood cancer. But often as you hear the ending of that, the name leukemia, we also think of it as a lymphoma, meaning patients can have the spectrum of an elevated white count like you might think of in terms of a leukemia. They can also, like a lymphoma though, have enlarged lymph nodes or spleen. And often patients are diagnosed incidentally and that just means that they’re…in seeing their physician or their medical team for other reasons. And they might have had a blood test, and their white counts elevated.

Or they might notice they have a tiny enlarged lymph node or found on screening for other cancers, for example. And so the takeaway there is that many patients don’t necessarily have symptoms and certainly often many patients don’t have reasons to need to start treatment at the time they’re diagnosed. So in terms of what it is today, I think more and more patients are being diagnosed both because it is something that comes about as patients get older, but also because it’s found during routine other visits. And so more and more patients I think are found incidentally that way.

Lisa Hatfield:

Okay, thank you. So just a follow-up question to that, if a patient goes into their primary care provider and finds something unusual that might indicate CLL, will they be referred to a hematologist right away at that point? Usually?

Dr. Danielle Brander:

So that is a great question. Often they are, for example, if they’re noted to have a high white count or, specifically a type of white cell called lymphocytes. However, there are many things that can cause that or cause a small lymph node. And so, some primary care appropriately, if those changes are small and they could be due to other things like an infection, for example, then their primary care might want to follow up first. And if things go away, it may not be related to a cancer at all.

But if it’s something that persists or it seems very out of range, or primary care, who, you know, are specialists and seeing kind of changes all the time, and may say this seems a little bit out of range, then even before something’s diagnosed, patients might be referred to a hematologist or an oncologist to help with that workup. But often because primary care is so astute in seeing these things, they may counsel patients to say, let’s send this test or this test to get things going while we’re speaking to a hematologist or oncologist.

Lisa Hatfield:

We have CLL patients and care partners who are newly diagnosed in active treatment, watch and wait, and also living well with their disease. Joining this program no matter where you are in your CLL journey, START HERE provides easy-to-understand, reliable, and digestible information to help you make informed decisions. So, Dr. Brander, we’re going to get into a more detailed discussion now of CLL. Can you talk a little bit about the novel pathways and targets that are currently under investigation in CLL, and what are the most important highlights from those for patients and their families and care partners?

And ultimately, and it’ll likely take many years to look at, ultimately the question is looking at if that helps prolong patient survival by having higher-risk patients receive that fixed-duration treatment earlier in time. We don’t yet have any results or any results to share, because the study is still enrolling.

But again, I think it’s something for patients to be aware of, because it does look at the higher risk patients. But around a year, it has to be within a year of diagnosis. So patients who are newly diagnosed, the question to ask your oncology team is “Do I qualify?” if it’s something you’re interested for, and they’ll help walk you through that. If you haven’t had markers checked, for example, it might be a good time to ask about that, to see if this is something would be available, even if not available though, it does create a time to talk to your team about the markers, because those can inform regardless of trial or not maybe what to expect in coming years and likelihood of treatment.

Lisa Hatfield:

Great, thank you for that. So as a cancer patient, one of the biggest questions I had when I was diagnosed, you hear the word “cancer” or in this case “CLL leukemia.”Two questions. One of them, is there a cure for CLL? And if not, are any of the…are there any trials looking at a cure for CLL?

Dr. Danielle Brander:

Yes. Excellent. An understandable question. Traditionally, we say that CLL or others slower-growing, or sometimes you’ll hear the term indolent lymphomas, do tend to be slower-growing.  Some patients don’t need treatment. But the flip side of that is we generally think of them as not curable, that they’re a chronic condition and that treatment, the goal of treatment is to knock it down and relieve whatever symptoms or indications or reasons you’re starting treatment are.

But at some level, we historically think of CLL as either eventually coming back or sticking around, so to speak. However, I think most oncologists, most those in the field, feel that some of the treatments that are around or in combination, that we’re going to have some patients that have maybe what a term might be functional cure or individual, cure-like condition.

Meaning if our newer treatments for some patients can knock down the CLL so much that it either doesn’t come back or take so long to even show itself again, in a way that serves as what the purpose of cure, really is, which is to get it down to levels that it’s not causing problems or not coming back, for the lifetime of the patient. Bone marrow transplant is the only therapy historically that has been cured, has offered a cure for some patients. The downside and the reason that most patients aren’t referred to for bone marrow transplant is the risk side of it. Meaning, unfortunately, a bone marrow or stem cell transplant has such a high risk of directly causing side effects.

That could be life-limiting or chronic side effects from the transplant itself versus the agents available now that we aren’t using or referring to bone marrow transplant nearly as much, but I think it’s really encouraging what we’re seeing in responses. So we talked already about those main categories of BTK inhibitors or venetoclax, I didn’t yet talk about, but there are many trials that have looked at those in combination, or CAR T, for example, or bispecific antibodies that are knocking down the CLL to such low levels. But the hope is that serves as a way of functional cure. But it’s going to take time to see if that’s the case. But we’re all very encouraged and really believe that that’s on the horizon.

Lisa Hatfield:

Great. Thank you so much. And even a functional cure sounds really hopeful, so I’m happy to hear that term. Thank you. And I want to be cognizant of your time and the time of everybody watching. So we are going to move into some of the questions that we’ve received from you watching this, patients. 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 and always consult with your own medical team. So, Dr. Brander, let’s start here. How do you explain, you kind of covered this a little bit, CLL treatment options and prognosis to your newly diagnosed patients? And I think that the prognosis piece is really important, especially if they do start treatment. 

Dr. Danielle Brander:

Sure, absolutely. So, what are the things we’re looking for in terms of needing treatment?  Because some of those, especially the symptoms we’re noting a lymph node or spleen, for example, or symptoms of anemia, which is low red cells or bleeding from low platelets, it’s helpful for patients to understand what we’re looking for, but, of course, in the time between visits those are the things we want to help patients with if they notice.

And so we encourage them all the time to call our triage or send us, you know, most electronic medical records now, have ways to send your team a message. And we want to know about that from patients in between visits. In terms of prognosis, as I mentioned before, there are other CLL-specific labs usually on the blood, meaning a regular blood draw.

Most patients don’t need another lymph node biopsy or a bone marrow biopsy, though that happens in some cases. And two of those or some of those key markers I mentioned before, but they test in the leukemia, there’s one test called the FISH, F-I-S-H, it’s not specific to CLL, we use it in other cancers. But it’s to look for specific changes in the leukemia genomics, meaning the DNA, the genetic material of the leukemia, not genetics you’re born with, but the cancer itself.

And there are specific patterns and that can be helpful as I sit down with patients to say this isn’t 100 percent, but this is kind of what to expect and likelihood of needing treatment over the next couple of years. There’s another test called IGHV, another mutation test TP53 kind of beyond this to go over right now, but as you mentioned, I think it’s important to meet with your medical team and say, ‘How does this pertain to me specifically?”

In terms of prognosis, I think there’s two parts to that of understanding what to expect. There’s likelihood of needing treatment, there’s likelihood of time to treatment, and those kind of markers and staging system help in a good way. Right now, our historical expectations, meaning 5 or 10 years ago, we could often also sit with patients and say, “This is the prognosis in terms of survival.” Expected life expectancy on average, but in a good way, most of our systems nowadays with the newer treatments likely vastly underestimate patient survival, meaning those systems were designed when we only had chemotherapy treatments.

Now, we know patients even with the highest risk markers, the faster progressions are living, you know, years and years beyond what was expected with chemotherapy. So I just caution especially materials around from just a couple of years ago that likely they don’t pertain, but they can be helpful in knowing what to expect.

Lisa Hatfield:

Great, thank you for that. Answering that question. We have a couple of questions about BTK inhibitors, and you already talked a little bit about the role of those and why they’re significant in treating CLL. But another patient’s asking about the, of course, a lot of patients wonder, what are the side effects? They hear chemo and like, “Oh, my gosh, the side effects are going to be off.” Can you talk about the side effects and even maybe some unusual side effects that you’ve heard of from patients when using the BTK inhibitors?

Dr. Danielle Brander:

Sure, absolutely. And so again, really important, these are things that as we maybe anticipate patients are going to start treatment, this is a long discussion of deciding between treatment, for example, as first treatment. There’s no trial saying one path is necessarily better than the other. So we try to individualize choosing between BTK inhibitors or that venetoclax-based therapy I mentioned. Some of that though comes about and what expected side effects are expected side effects for the individual. I try for patients to hear it from myself, other members of the team, the nurse, our pharmacist, for example.

And so patients shouldn’t feel overwhelmed to keep asking about what to expect or new side effects. There are some side effects we talk about regardless of the treatment. So I’ll just point out, anytime you’re starting treatment, you’ll hear the team talk about risk for infection, monitoring for fevers, reaching out to us about those kinds of side effects, lower blood counts that can happen regardless, not specific to BTK though it can happen there as well.

There’s some specifically though with BTK inhibitors, we ask patients to watch out for. Some BTK inhibitors can cause some cardiovascular side effects, meaning watching out for funny beating of the heart or what we call palpitations, skipped beats. There can be arrhythmias, some patients can have with time elevation in their blood pressure, for example. And then risk for bleeding, meaning BTK inhibitors affect how the platelets stick together similar to what aspirin does.

So the platelet levels may be normal but patients might have easier bruising, just generally manageable. But if there’s any kind of bleeding, certainly the team should be aware. It’s also the reason though, if you’re on a BTK inhibitor and you have a planned surgery or procedure, let your team know, because we may recommend or a lot of times recommend holding the medication before and after certain surgeries or procedures.

Other side effects can be muscle or joint aches. Some patients have some gastrointestinal side effects like looser stools or sensitivities to certain food causing looser stools, for example. And then there are some that are specific to the individual BTK inhibitor. This is the one point I’ll mention that first-generation BTK inhibitor ibrutinib, part of the reason for the second-generation zanubrutinib and acalabrutinib is not necessarily of them working better but to have less of these side effects that I just mentioned.

Lisa Hatfield:

Great, thank you for that. So this patient is telling us that he’s trying to plan life while living with cancer. It’s a challenge. It’s hard to know where to start. Can some patients go off of ibrutinib? I don’t say…ibrutinib after five years and enter a watch-and-wait kind of program. And will they be monitored during that time too, if they ever do go off of the medication?

Dr. Danielle Brander:

Yeah. So again, more excellent, excellent questions. So of those main categories of treatment, the BTK inhibitors are given continuously, meaning, at least so far, the standard way we recommend of those treatments is that they’re taken every day, either once or twice a day, depending on which BTK inhibitor, and they’re taken every day. Unless patients run into progression, meaning the CLL learns to grow through its resistance or patients run into side effects that despite maybe team’s recommendation of changing the dose or holding the medications, that it’s just the medication is just not tolerated.

In those cases, there are cases where we do recommend stopping the treatment because of side effects. And the key there is that patients if depending how long they’ve been on treatment or how their CLL is responding, might not need to go on to the next treatment right away.

So to answer this patient’s question, if they were to run into a side effect that wasn’t manageable, there are patients where we say, stop treatment and let’s just watch things, see if you need treatment, if your CLL has no other reason to jump into the next therapy. And there have been encouraging things that we’re learning and that I think are hopeful to this patient’s question, which is maybe in the future there are patients where we proactively can tell them to stop after a certain time because of what we’ve learned for patients so far. But at the current moment in time, we don’t tell patients to stop at a certain amount of time.

But there are trials that are looking at that after a certain number of years. And there are also trials that have followed patients who have stopped therapy and some of those patients, as I mentioned, who are told to stop treatment due to other side effects or other reasons, may go a long time, a couple of years before they need to start therapy.

Lisa Hatfield:

Okay, great. Thank you. I’m going to add one little question there too, if you don’t mind. So we’ve talked about trials a little bit, and I know that patients can go to clinicaltrials.gov, but what if a patient lives in an area that doesn’t have a major academic center or maybe trials aren’t being done very much in their area? Do you have a recommendation for patients? Should they just ask their doctor about trials if say, for example, they want to go on one of these trials? What recommendations do you have for those patients?

Dr. Danielle Brander:

Yes, absolutely. Starting with your healthcare team is very helpful to navigate to the right site. You mentioned the SWOG trial, which is online at a lot of the community and academic sites. So I would say also don’t or I encourage patients that just if they’re at a smaller site, it doesn’t mean there aren’t trials available. And then without going into all the individual, I guess societies and advocacy networks I really think that that’s been a tremendous benefit for patients is that there are societies through, you know, having leukemia or lymphoma, for example, that list or want to help patients connect them to what available trials there are.

Because while we think of trials as maybe the treatment, the reality is that a lot of trials are looking at other things too, patient’s physical function, patient’s other aspects of life besides the drug itself. So yes, I think that’s a great question for patients to be thinking about.

Lisa Hatfield:

Great, thank you. And you’re right, talking about access to trials is a whole other issue that will probably take up an entire program. But there are the advocacy networks out there, even Patient Empowerment Network. We can maybe help with that a little bit too. So we have another patient who is concerned about chances of relapse and is asking if there are any lifestyle changes through diet and supplements or anything that you can speak to that may enhance their response or their duration response to the treatment?

Dr. Danielle Brander:

Yeah. So a very very great question to bring about. And this is the one area, understandably where many of us feel frustrated because we can’t tell patients specifically that this trial has been done and says this specific diet is helpful or this specific lifestyle change is helpful to make the treatment work for longer. I think some of that is because some of the general advice we give meaning maintaining daily activity or a well-balanced diet sound non-specific or simple, but I think do help in patients staying in an overall general health wellness so that they can benefit from the treatment and potentially have less side effects from the therapy.

But getting back to the question we just talked about, I think certainly trials or studies really need to be continuing to look at this, because I think there likely are things that we can be more specific to patients about. There are studies looking at physical fitness and exercise regimens not necessarily specific to CLL, although there are studies being done in that space, but to other cancers showing that physical activity and exercise can help even for patients not on treatment maintain control of their cancer. So general daily activity and exercise are important in studies that look at how do you tailor that to an individual I think are important too?

Lisa Hatfield:

All right. So probably time for this last question from a patient. “As a CLL expert, how do you help empower your patients so they can get the most out of their CLL treatment and survivorship? How do you work with them as a team to make sure, I guess they’re having the best outcome they can?”

Dr. Danielle Brander:

Absolutely. So it starts at the start. I guess so for conversations, meaning for those that don’t need treatment right away building the relationship, understanding how I can help patients and their caregivers help, for example, they like to learn how much they want to know, what resources can I connect them with. And then I think it’s important for them to have other team members that they can go to and talk to and hear it from, because sometimes the same information we can just share in different ways or approach differently. The nurse on our team or our pharmacist or I work with a wonderful group of nurse practitioners and physician assistants as well. And so from the beginning, I want patients to feel free to ask the questions that come to mind.

It’s amazing, of course, during the course of the visit when you’re going over your labs and that, that sometimes it’s easy to forget the questions you came in with. So, of course, anytime you can write them down before coming in, write them down and then maybe prioritize because all of us…I think it’s hard to remember everything. So prioritizing the questions we want to make sure we get to and go over as well as know that these same questions are going to mean different things to you the longer you’re living with your CLL. And so it’s okay to ask the same questions. Again, there’s never a question that any of us mind going over several times. And then just know how the team can help you. You know, are you coming? How much information do you want?

How much input do you want us to put? And what is your importance and priority? At the end of the day, I want all patients to know no one knows what it is, like living with it. No one knows what’s most important as much as you and your family or your caregiver team does. And I learn just as much from patients and the way they share their experiences. There’s a lot we can look at a group of patients with CLL and say how different each patient’s experiences, who needs treatment or not, who has side effects or not. But no one’s going to know as much as as you do living with it. And it’s our hope to help you wherever you are in your journey or whatever ways that we can help you.

Lisa Hatfield:  

Well, and I appreciate your comment that we can ask the same questions over and over if we need to. I know my oncologist when I first met with him, I felt guilty taking in more than two questions, but right before he moved, I took in a long, I rolled up a piece of paper, a long scroll, and I said, I have some questions for you, but I knew they were all repeat questions. But it does give us a little bit of peace of mind just hearing it again from somebody, especially in those initial phases of treatment, just hearing it, even if you have to hear it again and again. So thank you for mentioning that. It makes us feel a little more confident in taking those concerns to our providers, even if they’re repeated concerns. 

Lisa Hatfield:

Dr. Brander, 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. And on behalf of patients like myself and those watching, thank you very much for joining us.

Dr. Danielle Brander:  

Thank you for having me.

Lisa Hatfield:  

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