Katherine Banwell:

Do side effects vary from patient to patient? 

Dr. Craig Cole:

Yes, so they actually vary greatly from patient to patient and from drug to drug. There’s some bispecifics for some cancers that have low risks of cytokine release so low that they don’t even need to come to the hospital. And some of them have such a high risk of those cytokine release syndromes that people are in the hospital for a few days.  

The other thing is usually the more tumor someone has, the more disease and cancer they have, the higher those risks of cytokine release. And so, it does vary from patient to patient to and from medication to medication. 

Katherine Banwell:

What should care partners understand about caring for someone during therapy? 

Dr. Craig Cole:

One of the big things that care partners should look for or to be aware of are – is the timeline for a lot of those symptoms. The highest risk for the side effects, the things to look out for, the neurologic toxicity, the fevers, and shortness of breath, and things are in the first few days of each dose of receiving therapy.  

Some of those therapies actually because of the neurotoxicity, they don’t let anyone drive, any patients drive for the first few weeks after receiving a bispecific. So, knowing the timeline, that in those first few days, that you really have to check the temperature, have a plan, know who to call, watch for those symptoms. But as the weeks move on, like after the second dose, there’s much less toxicity, third dose, even less risk. Fourth dose and on is very rare to have any of those toxicities, and so then you can relax. And usually people are able to drive. So being aware of the timeline’s important. 

Katherine Banwell:

Yeah. Are there advances being made in the management of side effects for bispecifics? 

Dr. Craig Cole:

Oh yes, and so that’s the – that’s one of the really exciting things is the – is what I was just talking to one of our trainees about this, about the evolution of the bispecific antibodies have been to make them more effective, make them more sticky, make them engage those T cells more while decreasing the toxicities. 

And so the ones that we’re seeing that are in clinical trials now that hopefully will be approved soon have less of those side effects, less hospitalization, and actually have a longer frequency of being given. The other thing is that we’re really beginning to learn a lot about treating cytokine release syndrome, especially as severe cytokine release syndrome. So, there was a drug that was used to treat severe COVID called tocilizumab (Actemra).  

Katherine Banwell:

Yeah.  

Dr. Craig Cole:

And that was used when people came in with COVID symptoms which can be a lot like cytokine release. The would receive this medication to help control that. Now we’re using that to treat cytokine release syndrome.  

And there’s quite a bit of data, especially in multiple myeloma in using it prophylactically to prevent cytokine release syndrome. And there are studies that show that the usual rate in multiple myeloma, kind of the specialty that I have, the usual rate of cytokine release – some cytokine release is about 70 percent with using prophylactic tocilizumab, which is just an antibody against one of those cytokines, IL-6. It goes down to – up to about 25 percent, so 75 to 25.  

And really it has no adverse side effects and doesn’t do anything with the outcome or the effectiveness of the bispecific antibodies.  

Katherine Banwell:

Well, that’s an incredible difference, isn’t it? 

Dr. Craig Cole:

Yes, yes, that was really – the trick is trying to get insurance companies to approve it and to get hospital systems to approve it.  

But I am very confident that very soon as we get more data about using it prophylactically that they’ll be incorporating it into the guidelines.

Transcript:

Katherine Banwell:

What is the role of a care partner for someone undergoing bispecific antibody therapy? 

Dr. Craig Cole:

Yeah, the care partner is, I think, a critical component of someone receiving bispecific therapy. And their reason is really to do with the side effects and monitoring the side effects of the therapy. What’s the big side effect of the bispecific antibodies is again when those T cells engage the cancer cells and they find the cancer, they release chemicals to destroy the cancer immediately.  

And those chemicals are from the T cells, can cause people to feel very ill, or can cause them to feel very ill very quickly, or they can have fevers, and they can have difficulty breathing. And that’s called cytokine release syndrome. Cytokines are the chemicals that the T cells are using to kill the cancer cells.  

Release, meaning that T cells are releasing that, and syndrome mean that different things can happen to different people. And the highest risk for the cytokine release syndrome is usually within the first two to three treatments, usually in the first two or three days of the therapy. And a lot of times when people get the bispecific antibodies, sometimes it’s given in a brief hospitalization like an overnight hospitalization, but then they go home.

And then the trick is monitoring for that cytokine release syndrome, the fevers that can be associated with that, shortness of breath, low blood pressure. And in having a couple people observing, watching for those signs and symptoms are really important. Because if cytokine release syndrome isn’t addressed immediately, it can progress to worse outcomes, meaning that the blood pressure gets lower, the difficulty in breathing gets worse.  

If let completely go, people can end up in the intensive care unit which is very, very, very rare. But that’s why we address this as early as possible. The other side effect, and probably kind of the most subtle thing, are some of the neurologic things that can happen with the bispecific antibodies. So, it’s the neurologic toxicity, or some people call it ICANS. And that’s when some of those cytokines that we talked about that are from the T cells can cross the blood brain barrier and cause patients to be confused.  

They can have word finding difficulties. They can feel – almost have stroke-like symptoms. They’re temporary, but they definitely need to be addressed. And sometimes patients may not be aware that they can’t find the right word, or they want to speak, and the words don’t come out, or when they speak it’s the wrong words are coming out.  

And that’s a real, real big sign that you need to call your doctor immediately, or your provider immediately if you have those neurologic symptoms. So, watching for those side effects, so low blood pressure, the high fevers, and stroke like symptoms. It’s not a stroke, but it’s just those chemicals in the brain that can cause people to have some neurologic problems. And again, if you address those immediately, they are definitely reversible.

Katherine Banwell:

So, after CAR T-cell therapy is completed, what potential side effects might people experience, and what should they look for?  

Dr. Beth Faiman:

Absolutely. I think of things in short-term and long-term side effects. So, the short term, you’re going to be admitted to the hospital and you have a risk for – when we get those T cells back – that cytokine release syndrome, or it’s abbreviated CRS – where you’re body’s immune system’s fighting.  

I tell folks it’s kind of like if you got a vaccine for a flu vaccine or pneumonia and you had a reaction it’s just way worse. So, you can get a high fever – the big first sign of this CRS. Usually, the providers will jump in with giving you a medication called tocilizumab (Actemra) or a similar drug that blocks IL-6, which is a chemical that is triggered when we get the CRS. And then, it stops those symptoms. And so, most of us know how to do that and will approve your insurance to get access to that tocilizumab or similar drug when we approve your CAR T-cell therapy.  

So, that CRS can get you really, really sick. You can get low oxygen levels in your blood. You can get a high fever and you can drop your blood pressure. But most CAR T-cells centers, the nurses and the staff are very well-trained to monitor this every eight hours, in most cases.  

Another rare side effect we worry about is ICANS, and it’s a neurotoxicity kind of thing.   

It can be with CRS or without CRS. But they’ll ask you to do things like write your name on a piece of paper every eight hours or tell me – draw a clock or count backwards from 100. And so, if you have any deviation, even minor, from what you reported back beforehand then we worry about neurotoxicity. Now, that’s short term but that’s the reason why you can’t drive a car for 30 days is because it could be delayed. 

The CRS can start with the one thing, the Ide-cel usually occurs within one day so most people are admitted to the hospital for that CAR T-cell therapy. The Cilta-cel, it onsets to about seven days. So, some people get the Cilta-cel outpatient and then are monitored daily, whether in person or through virtual telehealth monitoring.  

But at any rate, those are the short-term. Long-term, we worry about low blood counts maybe for the first month afterwards. And then, those will come back to normal. And then, we worry about infection. So, I mentioned the antibacterial, antiviral, which is usually a medicine called acyclovir (Zovirax), which most myeloma patients will have been on anyhow. And then, that IVIG to protect against viruses and bacteria when your immune system is so low. 

But fortunately, if we control the CRS, it usually comes with the CRS, although it can be independent. We try not to give steroids, because we don’t want it to interrupt the CAR T-cell process. But many institutions will give that tocilizumab for ICANS. And if that doesn’t get better then they’ll give you a steroid, such as dexamethasone (Decadron). 

And so, that will usually reverse itself pretty quickly. Longer term, after 30 days, you can get with the Carvykti, particularly something called Parkinsonian things where you can get a little bit shaky or something like that. Again, it’s very rare and I have had hundreds of people who have undergone the CAR T-cell procedure at my institution. And knock on wood, fortunately, I’ve not seen first-hand that side effect. And I think it’s because we’re so good now at treating the – preventing the ICANS and CRS as best as we can while they’re inpatient and doing real close following.  

One other thing I want to note is if somebody who’s watching this does go in the hospital for any reason, get up and walk around and stay strong, as well as you can, during the procedure. You might be bored if you’re in the hospital anyhow, but try to stay as strong as you can in the hospital. It’ll help your post recovery for sure.  

Katherine Banwell:

Well, what about more mild side effects like fatigue and changes in appetite?  

Dr. Beth Faiman:

Absolutely. So, the fatigue and the changes in appetite are generally mild for most but I see it, in my experience, if your myeloma’s acting up really quickly, if you’re having a rapid disease progression, the medications that we give you to control the myeloma during this bridging therapy phase might cause some of that as well, not necessarily the CAR T-cell process. But think about it. We’re using your own cells engineered to be fighters.  

And so, that first month or two is probably when you’re going to be the most tired as your body is being programmed to fight against the myeloma cells. That fatigue tends to get better. And as I mentioned just a moment earlier, the importance of just walking around in the halls, getting out of bed when you’re in the hospital, that can really help your post recovery. It doesn’t seem like much, but there have been many studies about how muscle mass declines, energy declines when you’re hospitalized.  

And we want you to be as strong as you can and thrive as much as you can for when you’re out you can then do the things you want to do at a quicker pace.

Considering CAR T-Cell Therapy? Key Advice From an Expert

Transcript:

Katherine Banwell:

Of course, we know that CAR T-cell therapy comes with some potential side effects. Let’s talk about some of those side effects and how they’re managed. You mentioned cytokine release syndrome earlier. Let’s start with that. What is it, exactly?  

 Dr. Adriana Rossi:

As I mentioned, cytokines are molecules that the cells of the immune system use to communicate with each other. With this therapy, we are asking the T cells that have been infused to expand, meaning make multiple copies of themselves, and sweep through the body looking for myeloma and basically picking a fight with them.  

So, CRS is what happens when the T cells are too good at their job and they overachieve and then picking a little fight kind of make a big ruckus. The result is what we call inflammation, which the patient will experience usually as a fever.  

But if it does not go – if it continues to go unchecked, that fever can be accompanied by low blood pressure because of these inflammatory markers, difficulty breathing or low oxygen levels. And all of these things are now vastly prevented. CRS is usually treated very quickly and doesn’t get to these higher grades, more complicated fields.  

Katherine Banwell:

How is CRS managed?  

Dr. Adriana Rossi:

We have a couple of very good antidotes. CRS by itself is not just a fever. Certainly, a fever in any patient who is undergoing these kinds of therapies, we will try to rule out any infections. But there are markers in the blood that we can follow. When the blood markers and the fever occur at the same time, we know that cytokines are driving that effect. If it seems to be driven by something we call IL-6, we use tocilizumab (Actemra). If it seems to be driven by IL-1, we use anakinra (Kineret). These are all drugs that are themselves monoclonal antibodies which then will shut down that overreaction and cool things down.  

Katherine Banwell:

Another possible side effect is neurotoxicity. Would you define that term for us?  

Dr. Adriana Rossi:

Yes. That one is harder to define because neurotoxicity in itself is very broad. We usually think of something called ICANS, which is the neurotoxicity associated with the effector cells. That specific neurotoxicity tends to happen in conjunction with CRS.  

And while CRS probably occurs in about 85 percent of patients, the ICANS is usually in the order of 5 percent. So, much, much more rare. And the antidote for that, which most patients know, love, and hate, is steroids.  

Katherine Banwell:

Ah, yes.  

Dr. Adriana Rossi:

I should mention there are other parts of neurotoxicity which I think the most concerning is something that has been known as Parkinsonian symptoms. It’s really just movement disorder. These are exceedingly rare and so we haven’t had a chance to learn very much because there are so few patients who have had this complication. We have learned from the first six patients who had this how to avoid it. And so, I think it’s now even more rare and it really goes into patient selection, to making sure, as I mentioned, that the myeloma isn’t growing very much.  

We monitor to see if the T cells grow too fast, if the CRS is of a high level. These are all predictors of delayed neurotoxicity.  

Katherine Banwell:

What are the signs of neurotoxicity in a patient?  

Dr. Adriana Rossi:

Very specifically, for the ICANS, we have tool called the ICE tool, which is a series of questions to test memory and attention and ability to write and understand and speak. So, most commonly, it would be an inability to speak properly or, if someone is writing a sentence, it’s really a very classic finding. It is no longer spread across the page.  

These are not subtle findings. Part of, again, being in the hospital is to allow us to have this tool twice a day and look for these signs very early on, interfere with their development by giving the patients steroids – usually for a day or two – and resolving it.  

Katherine Banwell:

And is there a potential for long-term issues associated with neurotoxicity?  

Dr. Adriana Rossi:

Certainly, there is always the potential. But the vast majority – again, the ICANS tend to be self-limited while the patient’s in the hospital, and that is why we’re watching during that window. The delayed neurotoxicities, in addition to these very rare movement disorders, we do see some cranial nerve palsies. The seventh cranial nerve, usually recognized as Bell’s palsy, has happened a few times. We really don’t understand the mechanism of what is driving it. It’s inflammation but why there, why that way. So, we tend to use acyclovir, which is the classic treatment for Bell’s palsy and steroids.  

Katherine Banwell:

Dr. Rossi, a suppressed immune system is something that a patient undergoing CAR T-cell therapy should consider. What does it mean, and what precautions should patients take?  

Dr. Adriana Rossi:

That is such a good question, and it is specifically true for patients who are receiving therapies that target BCMA, which both commercial CAR Ts at the moment target.  

Because it is such an effective therapy at bringing down cells that express BCMA, your immune cells that make antibodies, one of the side effects is the immunoglobulins, which are the antibodies, are all very, very low. So, that is one level of immunosuppression.  

The other is the chemotherapy that we use to quiet the T cells can also lower all the blood counts. So, red blood cells and platelets may be low as well and those are not involved with immunity and can be transfused. So, that is a supportive mechanism. For the immune therapies, we usually use IVIG, which is intravenous immunoglobulins to support the patient until they’re able to make their own.  

We also protect them from viral infections with acyclovir or valacyclovir. Protect them from something called PJP pneumonia, which is a virus that specifically appears when you’re very immunosuppressed. Should their neutrophil count be low, that is another type of white blood cell – make sure they’re protected with antibiotics.

Transcript:

Katherine:   

Are there other side effects that patients should know about and side effects that they might experience?

Dr. Patel:  

Yeah, so neurotoxicity is one that we don’t see as much as we see in lymphoma patients, which is again great but sometimes people can get something called ICANS, which is a type of neurotoxicity in the first 30 days after CAR T.

And basically, it can be as bad as seizures, but thankfully we don’t see that very often, or I haven’t seen it at all. But it can cause confusion. It can cause people to be extra sleepy. So, we have different treatments that we give to turn that around. Longer term, really, the big side effects are the counts being low. So, what we call cytopenias. So, white count, hemoglobin, platelets.

And so, that is something we see quite often in our patients who have had a lot of therapy for myeloma already, and then are getting something like CAR T.

So, a lot of my patients will still need transfusions even a month or two or three after, and we’re giving GCSF to help their white count come back up, et cetera.

Katherine:    

What’s that?

Dr. Patel: 

So, G-CSF is basically a growth factor that helps your neutrophil; so, a different type of white blood cell – come back up, which helps fight against bacterial infections.

So, it’s the same medicine for anyone who’s had a stem cell transplant. It’s the same medicine you get to get your stem cells into your blood but it’s at a lower dose. But again, it’s to avoid infections, to help present bacterial infections. The other one is infections can also be caused because of low IgG levels or what we call immunoglobulins; these are our antibodies that we have.

And the good news is, when CAR Ts or bispecifics or some of these immune therapies work really well, they’ll kill as many myeloma cells as we possibly can.

But they also kill good cells. So, they kill good plasma cells that make us antibodies and good B cells that make us antibodies. So, when that happens, people’s IgG levels will go down and that puts you at risk for infection too. So, we actually aggressively give people IVIG to help prevent those infections.
