Please speak to your healthcare team about what might be best for you. Well, let’s meet our guest today. Joining me is Dr. Jean Koff. Dr. Koff, welcome! Would you please introduce yourself?
Dr. Jean Koff:
Hi, I’m Jean Koff. I’m a lymphoma and CLL specialist from Emory University and it’s a pleasure to be with you here today.
Katherine Banwell:
Thank you for taking the time to join us. We start all of our webinar in our CLL Thrive series with the same question. In your experience, what does it mean to thrive with CLL?
Dr. Jean Koff:
So, I think thriving with CLL means that a patient is informed about their disease, they are comfortable with the physician who’s helping them navigate their disease and their management plan. And their management plan, whatever that might be, is really allowing them to focus on their life outside of CLL. So, keeping their symptoms to the absolute minimum, their physician keeping them informed about their disease progress, or lack thereof, in terms of keeping the disease at bay so they can focus on all of those things that bring them enjoyment outside of the CLL world.
Katherine Banwell:
That’s great. Thank you for your perspective. One part of thriving with CLL is managing the symptoms of the disease. What are the common symptoms of CLL?
Dr. Jean Koff:
So, one thing that I see with nearly all of my CLL patients, regardless of where they are in the CLL journey, and regardless of whether they need active medications to manage their CLL, is some degree of fatigue. And this can range from just mild fatigue that patients notice that they need a little bit of a breather in the middle of the day, to needing more sleep at night, to not being able to exercise as much as they’re used to. And that is by far one of the most common symptoms we see. Again, whether or not their disease needs medication to manage it. The classic symptoms of CLL that often let us know that it’s time to start medical management, are not just this fatigue. But the classic symptoms are B symptoms. And we describe those as fevers, night sweats, and unintentional weight loss. Those are very common. And then some patients with CLL will also have what we call palpable lymphadenopathy, which is our term for lymph nodes that are enlarged that you can feel. And the most common places to feel these on the body are on the neck, under the arms, and in the groin.
Katherine Banwell:
Okay. How are symptoms treated?
Dr. Jean Koff:
So, if your symptoms progress to the point that your doctor thinks you need medication – they’re becoming disruptive to your life, or they are getting worse and worse over time, then there are a variety of medications that we can use in CLL. And this is actually a very exciting field. Right now, the state of the field is that most patients who are starting on their first treatment for CLL will use some sort of oral medication, and that may be accompanied by an IV – what we call monoclonal antibody, or it may not. But one thing that has really changed even since I very first started practicing, is that we no longer commonly use what I would call conventional chemotherapy to treat CLL. Even though this was the standard of care just a few years ago.
Katherine Banwell:
Wow. So, a lot has changed.
Dr. Jean Koff:
Yes, definitely.
Katherine Banwell:
Why is it so important for patients with CLL to speak up and communicate with their healthcare team about some of their symptoms?
Dr. Jean Koff:
Well, for starters we want you to feel better. That’s our number one job as – as physicians, is we want to get you to feeling to – to where you are feeling like your best self. CLL or not. So, we want to make you feel better. But in CLL your symptoms are actually one of the criteria we consider when we’re thinking about whether or not we need to start a new therapy, or if you’re somebody who’s already on therapy, whether we need to change your therapy. So, it’s actually very important and your CLL doctor should be checking in with you regularly to see if you have new or worsening symptoms that might be due to your CLL.
Katherine Banwell:
Mm-hmm. It sounds like treatment of the disease is key to controlling your symptoms. So, let’s talk about treatment. Many patients are overwhelmed by the different types and classes of treatment. When is it time to treat CLL, and what are the options?
Dr. Jean Koff:
So, I boil down the criteria to when you need to treat your CLL to two main categories. One category is that the disease is progressing quickly, and the other category is the disease is causing problems of some kind, or getting ready to cause problems of some kind. Those are some of the broad categories that we think about when it’s time to start treatment for CLL. Now, this – the groups that research CLL have put out various criteria that help guide physicians about when it’s time to start treatment and some of those more specific criteria include items like symptoms. So, symptoms are a very important part of that decision-making process.
And the same symptoms that we mentioned, the B symptoms, fevers, chills, night sweats, weight loss that’s unintentional, or lymph nodes that you can feel, those would potentially be reasons that your doctor would want to start you on CLL therapy. But the CLL can cause issues even in a patient who’s not necessarily having symptoms. So, one of the most common ways that CLL can cause issues is the CLL cells can cause your other blood cells, the normal blood cells, to be low in number. There are several ways the CLL cells can do this. One of the most common ways is that the CLL cells which are often circulating through your bloodstream can also collect or overrun your bone marrow.
And if you think about it, the bone marrow is the factory that makes all of your blood cells. So, when there are too many CLL cells in the bone marrow, they can crowd out the normal blood cells, like red blood cells or platelets. So, when red blood cells or platelets get low beneath certain thresholds, that’s a reason to start CLL therapy.
Katherine Banwell:
Mm-hmm.
Dr. Jean Koff:
So, there are a couple other criteria that we think about. CLL cells can collect in other areas, including the spleen. So – and if you remember, the spleen is a lymphoid organ that sits on the left side of your body that is right below the stomach. And so, if CLL cells collect in the spleen, they can cause it to be too big, it can press on the stomach, it can make it so you feel full, even if you haven’t eaten a full meal, that’s something we call early satiety. It can be uncomfortable, causing some abdominal pain. And if the spleen gets really, really big, it can cause it to not be able to do its normal job, which is to filter out the normal blood cells like it does every day. And so, that would be a reason to start therapy as well. And then the last – the last category I would think about is in CLL we have lots of – of CLL cells that are circulating in the blood that we can check with a routine blood count. And the absolute number of CLL cells is not as important as how fast that number is growing. So, your physician will track how fast that number of CLL cells is doubling.
And if you meet criteria for what we call rapid doubling time, which is usually thought of as less than 12 months but certainly less than six months. So, if your count goes from 30,000 to 60,000 in under six months, then it may be time for you to start thinking about therapy.
Katherine Banwell:
Right. So, Dr. Koff, would you briefly review the treatment classes?
Dr. Jean Koff:
So, for first-line treatment, we have two main treatment classes that we think about at this time. The first is – is called BTK inhibitors which is Bruton tyrosine kinase inhibitors. And these are oral medications, so medications that you take by mouth, and the most well-studied of these is called ibrutinib, we typically prescribe ibrutinib by itself. There are other BTK inhibitors we are also now using in this space, one of them is called acalabrutinib and that is often given with an IV monoclonal antibody called Obinutuzumab.
The other main class of drugs that we consider for first-line treatment of CLL is the BCL-2 Inhibitors. Right now there’s only one BCL-2 Inhibitor that’s approved for CLL and front-line and it’s called venetoclax. Usually, this drug is also given in the front-line with an anti-CD20 monoclonal antibody. So, the venetoclax itself is a pill you take. And the monoclonal antibody is an – either an IV or a subcutaneous injection.
Katherine Banwell:
Where do clinical trials fit into CLL treatment?
Dr. Jean Koff:
So, clinical trials are part of the reason, a big part of the reason that we’ve been able to make so much progress in how we treat CLL over the past few years. Clinical trials are how we figure out what treatments work for CLL, how patients feel on them, what sort of adverse events or side effects they have on individual treatments, and which treatments do better for keeping CLL symptoms under control, keeping the disease under control, and allowing patients to live longer and have a higher quality of life with their disease.
Katherine Banwell:
Are there any other options available for CLL patients?
Dr. Jean Koff:
So, there are other options. A clinical trial, if that is available to you as a patient is nearly always a good thing to consider if you have CLL. Because the vast majority of patients will not be cured by CL – by their treatment for CLL. Meaning that the – even though the treatments we have usually work for a very long time in most patients, ultimately the CLL will at some point, perhaps years down the road, progress and need another therapy. For that reason, we know we can do better. And we are hoping that the next clinical trial is going to lead to the discovery of a new agent or a new combinations – new combinations of agents that will allow patients to live longer with a better quality of life with CLL.
Katherine Banwell:
Mm-hmm.
Dr. Jean Koff:
So, that’s always a good option to consider.
Katherine Banwell:
Mm-hmm. What are the common side effects of treatments, and how are they managed?
Dr. Jean Koff:
So, each of the different classes of agents has a different profile of side effects. The BTK inhibitors, the first class that I mentioned with ibrutinib and acalabrutinib, are usually very well tolerated. The most common side effects that we tend to see are things that the patients can feel or see, but also things that we can see on the labs when we’re monitoring patients. So, sometimes you can see a lower platelet counts or lower cell counts with ibrutinib. That’s something that you may not notice, but your doctor’s going to notice on the – the blood counts when you come to the office. Sometimes ibrutinib can cause a rash or GI upset, this is usually easily managed with supportive care from your physician.
And then some more – some more common effects of the BTK inhibitors include joint pain and headache. And again, many physicians, because we’ve been using BTK inhibitors for a long time, have a good regimen for treating these side effects. More uncommon side effects of BTK inhibitors, particularly ibrutinib that we look out for would be abnormal heart rhythms and some tendency for bleeding. But these are relatively uncommon and with newer BTK inhibitors, we’re seeing lower rates of these side effects.
So, in terms of venetoclax side effects we have a little bit of a different profile. This agent is much more likely to cause lower cell counts, especially in a white blood cell count known as neutrophil count, and so your doctor will be monitoring you for that. In terms of patient side effects that you can feel, it can cause a rash, it can cause some GI upset. These are usually relatively easily managed but we want you as the patient if you’re on venetoclax to talk to your doctor about these side effects so that they can help you feel better and help you manage those. In terms of the anti-CV20 monoclonal antibodies, which we use a couple in CLL more frequently, they have very similar side effect profiles.
So, one is rituximab, and one is obinutuzumab. Obinutuzumab is usually used in combination with venetoclax in front-line CLL.
Like I mentioned before, this is an infusion and most of the side effects that we think about and most commonly see in these anti-CV20s are side effects that patients have during the infusion. And these are referred to as infusion reaction. And these are relatively common, around 30 percent in these anti-CV20 monoclonal antibodies. So, what is an infusion center react – er sorry, what does an infusion reaction look like? This looks sort of like an allergic reaction.
Katherine Banwell:
Hm.
Dr. Jean Koff:
So, your nurses in the infusion center are going to be monitoring you very carefully once you start the infusion, and they’re going to start it at a low dose, very slowly. But the side effects they’re monitoring for, they’re looking for changes in your heart rate or blood pressure. You may start to feel hot or cold or sweaty, you may have chills. Sometimes patients can have swelling in their throat or their tongue. And what will happen is because these are fairly common, is we’re still able to give the anti-CV20, but what we do is the nurse will stop the infusion, they may give you some medications that calm down that infusion reaction. So, medications
like antihistamines –
Katherine Banwell:
Mm-hmm.
Dr. Jean Koff:
Or steroids that help tamp down that immune response, and then they start the anti-CV20 infusion at a lower rate. The vast majority of patients will be able to receive an anti-CV20 antibody even if they have an infusion reaction. They may just need a little bit more of those immune-tamping down medications like antihistamines and steroids. And then the last thing to consider, which I think we’ve mentioned, especially in the venetoclax-containing regimens, is the Tumor lysis syndrome. And so, that is a side effect like we mentioned is kind of like the venetoclax working really, really, really well, of the tumor breaking down too quickly.
And so, patients who have Tumor lysis, if they’re at high-risk, hopefully they’re already being monitored very closely with frequent lab draws, and they may receive medications that – that diminish the risk of adverse events happening because your electrolytes are out balance, for instance, your potassium is too high, or your calcium is too low. Because your doctors are monitoring you closely, they can give you medications that can help balance out those – those electrolytes and help protect the kidneys. The Tumor lysis is typically not a risk after the initial doses of venetoclax.
So, the first couple weeks is when we typically monitor that, and then once the CLL has been broken down, or as I like to say, once it’s been cooled off a little bit, then you no longer have this risk of Tumor lysis and it – it doesn’t require further monitoring.
Katherine Banwell:
That’s great information, thank you. What is the patient’s role in deciding on a treatment plan?
Dr. Jean Koff:
So, it’s very important that the patient be involved in deciding on a treatment plan. Especially in first-line. Because we have these two excellent classes of agents, the BTK inhibitors and the venetoclax- containing regimens. Both of them have been shown to have very good what we call efficacy in CLL, meaning that they’re able to control the disease, patient’s symptoms largely at bay for long periods of time. You know, we’re talking an average of years that – that patients are on these therapies. And they each, like I said have different side effect profiles.
And they’re given in slightly different ways. And so, right now we don’t have data from our clinical trials comparing a BTK inhibitor regimen to a venetoclax-containing regimen in CLL patients to tell us one is better than the other. And so, for that reason, a lot of the decision-making about which therapy is going to be better for you, or which therapy you would prefer, lies with the CLL patient rather than with the doctor. And the things that I ask my patients to consider, there are a couple different things. One is the side effect profile. So, patients may be more or less comfortable with certain side effects of one drug compared to another. Or there may be something in the patient’s medical history that puts them more at risk for a certain side effect than another.
The other major player in this decision-making process is how these drugs are given. So, with ibrutinib, the ibrutinib is given as a pill that you take once a day, and you take it indefinitely. Meaning you take that pill once a day for as long as it’s doing what it’s supposed to do, which is keeping your CLL under control, and as long as the patient is tolerating it well. Meaning you’re not having a lot of uncomfortable side effects from the ibrutinib. So, I have patients who have been on ibrutinib for years and years and years and years.
The venetoclax-containing regimen for patients who are getting their first-line treatment in CLL is different. It is designed as a – what we call time-limited therapy. And so, this regimen is given in – over about 12 months, 12 or 13 months, and then stopped. As long as the patient has had a good response. The other thing to consider with the venetoclax regimen, it’s not just the pill. You do take a pill every day, but you also get a – an infusion for about six months of the monoclonal antibody. Meaning that you’ll have to come into the infusion center and get an infu – an IV infusion of this drug called Obinutuzumab. The last consideration with the venetoclax regimen that differs in how it’s administered, is the venetoclax often works so well that it can break down the CLL cells a little bit too quickly.
And so, for patients who have a very, very high white count, or large lymph nodes due to their CLL, there is a risk of something we call Tumor lysis syndrome, which refers to the process where the tumor cells break down very, very quickly, and they produce molecules that are released into the bloodstream that can be dangerous if they get too high or too low. And so, sometimes, in some patients we have to monitor for the Tumor lysis syndrome by checking labs fairly frequently after we start the venetoclax. And for some patients that means they have to stay overnight for a night or two in the hospital for
