Katherine Banwell:

You mentioned one inhibitor as targeted therapy, but there are a couple of others. Would you briefly tell us about those? 

Dr. Gail Roboz:

So, over the years recently, we have identified certain specific targets in AML which are resulting in the addition of medications on these standard backbones. So, the target for venetoclax (Venclexta) is something called BCL2, and actually, venetoclax probably makes all chemotherapy better. It’s kind of a controversial statement, but I’m going to stand by it. But in AML, it has been shown that the addition of venetoclax to lots of different backbones makes them work better. There are other things to hit, though.  

For example, there are patients with AML who have something called a FLT3, F-L-T-3 mutation. This mutation also has specific inhibitors that are FDA-approved drugs that target specifically the FLT3 mutation, and if you have one of those, your doctor may add on a FLT3 inhibitor to either a lower intensity or an intensive backbone. Similarly, there are agents called IDH inhibitors. There are IDH1 and IDH2 inhibitors. 

If I start getting into isocitrate dehydrogenase pathways on this webinar, I think everybody will click off, because it’s certainly bored all of the medical students in med school, and it’s pretty tough to understand. But the bottom line is it’s very cool stuff because that boring pathway in medical school that nobody really thought about too much is actually part of very, very, central cellular functions that are a vulnerability now that have been identified in leukemic cells that, if you hit them with these specific inhibitors, patients do better.  

Now, couple of things for patients. It doesn’t mean that it’s better to have a FLT3 or an IDH mutation because the targeted therapies are available. So, a lot of patients are disappointed when they don’t have mutations. I don’t want you to think in that way. It’s not that it’s better, it’s different.  

It identifies a different biology. If you have certain mutations, there are certain medications that may help you more.  

That’s why I think the patients are learning quickly, too, to ask the doc – they may not remember the letters of the alphabet soup, but “Do I have something about my AML that can get one of these targeted therapies added on?” I think is a good question to think about. “Do I have something about my disease that has a specific drug that we’ve already learned makes outcomes better?”  

Katherine Banwell:

There’s a new emerging therapy as well. Is it the menin inhibitor? 

Dr. Gail Roboz:

I think that, in understanding different targets and different pathways, it leads me to a general statement that if you can get yourself potentially onto a clinical trial at an academic center, that is something to consider right out of the gate. Because there is a lot, a lot, a lot going on in this field right now. 

What we are hoping, and the reason that I am talking to you about venetoclax and FLT3 inhibitors and IDH inhibitors, is because of all the patients who jumped onto those clinical trials and proved that those drugs are better. Some of them are my patients! I was fortunate on some of those early trials to have some real winners in patients who got onto the trials. They’re the ones who drove the success. 

So, for example, menin inhibitors, which are very, very exciting, targeted agents for NPM1 and KMT2A mutations and rearrangements – these are complicated to remember as a patient, but there’s a cool drug out there that might be for you.  

I think that patients who really think about asking the question wherever they are, the “Hey, I just got a diagnosis of AML. Is there a clinical trial that might look good for me?” I think is a great question to ask pretty much out of the gate.

AML expert Dr. Omer Jamy discusses his approach when considering treatment for patients with relapsed or refractory AML, including transplant eligibility, molecular markers, and whether clinical trials may be an appropriate option.

Katherine Banwell:

Dr. Jamy, are there any recent advances that may affect the care of patients with relapsed or refractory AML? 

Dr. Omer Jamy:

Yeah, that’s a good question. So, patients with relapse refractory AML, of course, carry a poor prognosis. That means that chemotherapy was working and has stopped working or chemotherapy didn’t work from the get-go, right?  

So, in my practice I try to divide patients into two different buckets. One is that I need to get them into remission, and they’re fit for a transplant, so I take them to transplant.  

So, then my treatment approach is a little different for those patients. As opposed to someone who’s elderly or too frail, that they may go into remission, but they may not be able to proceed to stem cell transplantation after that.  

So, what happened in the relapsed/refractory setting also depends on what the patient received in the upfront setting. Ideally, I would recommend a clinical trial enrollment for patients with relapse refractory AML if they have access to it. At the time of relapsed/refractory AML, it is very important to again profile the leukemia to see if there are any mutations that were present at diagnosis or if there are any new mutations for which there may be targeted therapy. Some of those mutations for which we have targeted therapy include FLT3-ITD for which there is a drug called gilteritnib (Xospata), which is FDA-approved in the relapsed/refractory setting. 

We spoke about IDH 1 which is ivosidenib, IDH 2 which is enasidenib (Idhifa) is also approved for patients with relapsed/refractory AML. And then more recently the FDA approved another IDH1 compound called olutasidenib (Rezlidhia) which is also for patients with relapse refractory acute myeloid leukemia with an IDH1 mutation. I think these are target therapies which have shown to get people into a second remission and beyond. And these have been approved in the last few years. And I think it is very important to basically test whether the person harbors these mutations so that we can target them accordingly.  

For patients who don’t have any mutations we would generally, outside of a clinical trial, probably use the combination of some of the approved agents that may be venetoclax (Venclexta) with azacitidine (Vidaza) or decitabine (Dacogen). Patients who may have received this venetoclax or a hypomethylating agents frontline and may still be eligible for intensive chemotherapy.  

You could offer them intensive chemotherapy in the relapsed/refractory setting, but I would say that at this point being at a center where there’s opportunities to enroll in a clinical trial would be really helpful as well.
