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.

Now, in reference to immunotherapy and CAR T-cell therapy, who are these types of treatments right for?

Dr. Patel:    

So, I think it’s really exciting that we finally are getting standard of care therapies for all these new immune therapies. So, our first CAR T for myeloma got approved a little over a year ago. Our second CAR T got approved just a couple of months ago, and we’re hoping our first bispecific will be approved in just a couple months.

Our fingers crossed. On the clinical trials, I will say our patients who had a good performance status, meaning they’re able to do everything else normally life-wise, those are the patients that got onto those clinical trials; and the reason is safety-wise.

So, T cells when we use them to kill myeloma, they release cytokines or enzymes, you can say, that are inside the T cells and that’s what they use to communicate with other immune cells to come help them kill.

Those are the same cytokines that make people feel really ill when they have the flu, for instance. So, as our immune system tries to fight infections when people get fevers, they feel chills, they feel just fatigued and tired, it’s those same kind of cytokines that, even when you try to kill the myeloma with T cells, people can get that same type of symptoms.

And really, the main, fevers and things like that, we can take care of. But when patients’ blood pressure drops or if their oxygen levels drop really low, that’s where we can run into some trouble. Now, the good news is, in myeloma, most of these new therapies don’t cause really bad CRS [Cytokine Release Syndrome] or really bad neurotoxicity that we can sometimes see. And so, thankfully most patients are okay, but really it’s making sure that none of our patients have bad toxicity. So, most of our myeloma patients, I will say, are eligible for these therapies. However, if someone has really bad heart disease or really bad lung disease, those are patients that maybe these are not the right therapies for.
