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.


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.

Would you define induction therapy and consolidation therapy and tell us what the differences are?

Dr. Carraway:            

For most patients that are diagnosed with an acute myeloid leukemia, over the last 30 to 40 years we’ve used an intensive chemotherapy regimen that we call induction. Induction means that we’re trying to get the leukemia into remission with an intensive chemotherapy regimen. Classically, that has been two agents; one, a cytarabine based regimen along with an anthracycline, either idarubicin, danorubicin, or some anthracycline that’s similar.

Now, the cytarabine based therapy is a continuous infusion over seven days. The anthracycline is given over three days as an intravenous IV push, and so that’s why it’s kind of been nicknamed seven and three – seven days of cytarabine and three days of another anthracycline.

Now, that has constituted the induction intensive regimen in the hospital with the idea that that leukemia gets under control and goes away. More recently for patients, they can receive therapy that is not this inpatient, in-hospital, induction chemotherapy but rather use oral therapy combining with venetoclax, which is a Bcl-2 inhibitor, along with azacitidine, which is either IV or subcutaneous given to patients over seven days. The oral, venetoclax is every day.

That type of induction can also be given and is now an outpatient regimen and more often offered to patients that are older, over the age of 75.

That, too can be considered induction with the idea that once a patient is diagnosed with leukemia this regimen is started, and after one month or even two months on venetoclax plus azacitidine patients’ leukemia can get into what we call remission, where the blast percentages are less than 5 percent. Then, normal hematopoiesis of platelets being greater than 100,000 and a neutrophil count greater than 500 or 1,000, and the patient is then transfusion-independent.

In general, induction chemotherapy is that first round of chemotherapy that’s trying to get the leukemia under control.

Consolidation chemotherapy is when you use subsequent cycles of chemotherapy to keep the leukemia under control because we know that if we don’t continue to give some continuation of therapy that the small, little seeds of leukemia will re-emerge and leukemia will relapse.
