So another person is asking, “How long does it take for the immune system to really start bouncing back after follicular lymphoma treatment? And what blood test results indicate a weakening immune system?”

Dr. Kami Maddocks:

Yeah, so this is a great question. It also can be a complicated question with many different answers. So one, it can depend on the treatment that a patient receives. Two, it can actually depend on their different parts to the immune system. So different parts of the immune system can recover at different time periods from treatment. So acutely, our neutrophils are something that often gets…they’re bacteria infection fighting cells. Those are the cells that during chemotherapy, when that count gets low and patients are counseled on if you have a fever during your treatment, you need to be evaluated and be seen because if you have an infection and a fever during chemo or some of these treatments, your blood counts are low, you might need to be in the hospital on IV antibiotics.

So those neutrophil parts of it are usually quicker to recover, so they drop with treatment and then recover pretty quickly with each cycle, including after an ended treatment cycle. Sometimes when patients have been treated with several different therapies, it can be harder for those cells to recover. They can stay lower for longer. Then there’s a component of the immune system, so we are ripping out the lymphocytes, because that’s what the cancers have.

And so things targeted. Chemotherapy in general kills the lymphocytes, but there also are targeted therapies like rituximab (Rituxan) bispecific antibodies CAR-T cells, those are particularly wiping…targeted towards proteins on the lymphocytes and wiping them out. Those can be for a more prolonged time. In general, we usually think of about a six-month period so patients can be at increased risk for viral infections in that six-month period may not respond as well to vaccines in that period.

But for some patients it takes longer and some patients recover quicker. It also can depend on where patients are at in their journey because every therapy that they’ve had can take a little bit longer to recover. The last part I’ll add is just sometimes when the lymphocytes are wiped out for a long time people’s proteins, their immunoglobulins that help fight infection get low. And so sometimes we actually will end up giving patients replacement of IVIG to help if they’re having lots of infections.

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

Katherine Banwell:

Is there a typical timeframe for the immune system function to return?  

Dr. Adriana Rossi:

I would say a year is a good time but it’s a very unpredictable wave. So again, unlike stem cell transplant where you have a clear time where the cells are low, they recover, they stay recovered, we have noticed for some patients, they may have low blood counts just during the first month and then be recovered. Some will have no problems in the first month and it’s in the weeks to follow that suddenly either the reds, or the platelets, or the white count may need support.  

And in very rare instances, out to a year, they’re still needing support, sometimes say a growth factor injection once a week.  

Katherine Banwell:

So, how is it monitored over time?  

Dr. Adriana Rossi:

We monitor all those different levels of the immune system. So, we check on the CBC, which is the very common blood counts. We also look at what is called a lymph panel to look at the different types of T cells and make sure that they are recovering. Those usually take about three to six months to recover. The white count, again usually by Day 30, but there are some cases of delayed recovery. And the immunoglobulins, which is the antibody level, we also monitor monthly.  

Katherine Banwell:

What other side effects should patients who are considering CAR T-cell therapy be aware of?  

Dr. Adriana Rossi:

Really, those are the big three. I would say others are very rare but the low blood counts is the one that lasts beyond the time in the hospital. And the rare neurotoxicities that are delayed.  

Katherine Banwell:

When should patients mention any issues they’re experiencing to their healthcare team?  

Dr. Adriana Rossi:

Always. That is a very, very, short answer. Please don’t ever think you are bothering the doctor. I hear that a lot. “Oh, I didn’t want to bother you.” It is never a bother. This is why we are here. So, anything that is happening that is out of the ordinary, please let your healthcare provider know. If it is not something that needs our attention or we don’t need to worry about, we will tell you.  

Katherine Banwell:

Better safe than sorry.   

Dr. Adriana Rossi:

Always.  

Katherine Banwell:

And how does a care partner factor into the process? It seems having a good support system is essential.  

Dr. Adriana Rossi:

It absolutely is. I think the entire journey of myeloma really is what I would consider a team sport. It is not something we go through alone. And the more members of the team you have the better. So, as your medical team, we always value the caregivers. For CAR T specifically, since there is this concern for infections and neurotoxicity, caregivers are really essential.  

They should be well informed, know what to look for, and be the ones to reach out to us if anything is concerning. Again, any symptoms out of the ordinary, any fever, and really be a part of communicating with the medical team.   

Katherine Banwell:

Is there a period where patients are considered out of the woods from CAR T side effects?   

Dr. Adriana Rossi:

Hard to say. Again, I like to emphasize that most patients by Day 30 or 60 are back to work, are feeling themselves, are recovered. Another contrast to stem cell transplants. It’s a much faster recovery. I have patients who within 30 days are eager to go back to work and don’t know what I was talking about or why I insist on seeing them so much.  

But some patients, again, out to a year, may still be requiring visits for support in either the IVIG for the immunoglobins, growth factor support for their counts. So, there are outliers at both extremes. We follow the model of 100 days for recovery.   

Katherine Banwell:

Do some patient types do better than others?  

Dr. Adriana Rossi:

Well, always yes. And we are still endeavoring to figure out who they are and why that is. There are things that we don’t know, can’t predict. But things that we do recognize are again bringing patients whose myeloma is under good control.  

So, instead of having a lot of disease or disease that is in a growth phase, we try to use the bridging therapy to optimize the patient, not only to improve the response, but also minimize the toxicities. 

Katherine Banwell:

Does age have an impact at all?  

Dr. Adriana Rossi:

Not as much. We actually have just finished an 88-year-old patient whose hospital course was remarkably unremarkable, as we would like. I think another difference from stem cells, it is not as rigorous. While each patient, I think, should be part of that decision and that conversation, reviewing what is now a growing number of options and see if it’s right for them as an individual. So, age is a consideration, but frailty will always be the more important.

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.
