AML Treatments and Clinical Trials

When it comes to treatment, AML patients and their care partners have much to consider. There are often many options available, each with advantages and disadvantages. Some people may seek clinical trials, others may have few feasible options. Understanding treatment options, goals, and what to expect are vital to achieving the best possible outcome for you.

Dr. Lai, what is MRD-positive AML?

Dr. Catherine Lai:

So, that’s a really good question. And to answer that question, I’m going to actually answer a different question, which is, What is the definition of complete remission? So the definition of complete remission is when we do a bone marrow biopsy, and we have less than 5 percent of those blasts or leukemia cells in the bone marrow, and that is also in the setting of a relatively normal immune system or normal other blood counts have improved, so that your neutrophil count is above 1,000, and your platelet count is above 100,000. So, MRD, which stands for measurable residual disease, means that you’re in complete remission, so you have less than 5 percent blasts, but you’re more than zero.

And we, in general, when patients who are MRD-positive, we know that if you were to do nothing, that those patients have a high likelihood of relapse. We know for the patients who are going to transplant, if you’re MRD-positive before transplant, those patients also have a higher likelihood of relapsing after transplant. And so we tend to monitor it if possible…the tricky thing is, is that there is not a standard way to measure MRD testing as of yet, the common approaches are right now are with either flow cytometry or with PCR or next-generation sequencing, if you have a particular targeted mutation that we can follow.

So your activation from that standpoint is to ask if MRD testing can be done on your bone marrow biopsy at the time at which you or after you’ve had your chemotherapy.

Dr. Lai, what is FLT3 mutated AML and what treatment options do patients with FLT3 AML have?

Dr. Catherine Lai: 

Yeah, so FLT3, FLT3 mutations occur in about 25 percent to 30 percent of patients. There are two different types of FLT3 mutations. There’s a FLT3, the ITD mutation and the FLT3, the TKD mutation. They just are there, different parts of the mutation on different parts of the cell, and so how I think about that is, if you think of a leukemia cell and each leukemias has a different color-coded flag, and so the FLT3 mutation I think of is just having a specific color coding, and while a FLT3 mutation in general does predict for a worse prognosis for patients, we do have targeted treatments. In a newly diagnosed setting, we have midostaurin (Rydapt), which is added to intensive chemotherapy for those fit enough to tolerate it. 

And in the relapsed refractory setting, we have a medication called gilteritinib (Xospata), which is given as a single agent, so a chemo pill, and that was compared to all types of chemotherapy, both intensive and low intensive chemotherapy, and that pill alone and the refractory and relapsed setting was better than either of the chemotherapies alone, so we’ve made a lot of progress for the FLT3-mutated patients to the majority of those patients end up going to transplant if possible, and so there are studies that are looking at FLT3 inhibitors in the post-transplant setting to also help improve long-term survival and overall survival. So the activation tip from that standpoint, that is to ask your oncologist, if your FLT3 mutation testing was done, ask which type of mutation they have, if it’s the ITD or TKD, if they are FLT3-positive and what the drug options are available for them.

Dr. Lai, for newly diagnosed AML patients, what are the latest available therapies?

Dr. Catherine Lai:

That’s a great question. The last, I would say, a handful of years have really seen a dramatic increase in the number of new treatment options for AML patients, specifically since 2017, the FDA has approved 10 new drugs for AML, that’s both for patients who are newly diagnosed and in the relapsed refractory setting.

And so what I would say is that we break our patients into two different categories in terms of being able to tolerate intensive chemotherapy versus non-intensive chemotherapy, and as well as looking at specifically targeted mutations that patients may have so that we can better understand the disease but also treat these patients more specifically to try to maximize efficacy while minimizing toxicity. 

And so specifically, I would say for patients who have FLT3 mutations, there are drugs such as midostaurin (Rydapt) and gilteritinib (Xospata), there are drugs for mutations in IDH1 and IDH2, enasidenib (Idhifa) and ivosidenib (Tibsovo) and recently, or in December of  2022, olutasidenib (Rezlidhia) was also approved for IDH1-mutated patients as well.

We have a general targeted agent that’s an oral chemotherapy that probably has made the biggest difference in how we treat patients called venetoclax (Venclexta), and that’s used in combination with azacitidine (Onureg) or decitabine (Dacogen), or low dose cytarabine (Cytosar).

Although most commonly in the United States, we use azacitidine or decitabine in combination with the venetoclax, and that I think is really what I’d say has been practice changing for the most part, in terms of both increasing the complete remission rates as well as the overall survival for these patients. So I would say there are a lot of new drugs. It is all very exciting.

The biggest activation tip in terms of takeaways is to ask your physician and your oncologist when you’re talking with them about what all the newest therapies are and what would be specifically the best treatment for their specific leukemia with respect to the different mutations.

Art:

Okay. Dr. Lai, what are the latest approaches to combination chemotherapy to treat AML?

Dr. Catherine Lai:

So, the latest approaches for combination chemotherapy would be in the combination of a hypomethylating agent, azacitidine or decitabine in combination with venetoclax. This is the most practice-changing combination that has been approved since 2017 to 2018, and now more recently, what’s been happening is now looking, so we call that a doublet, and now it’s been looking at…what we’ve been studying is now whether or not triplets are more effective, when we do have triple combinations, we do see an increase in toxicity and so on, we haven’t come up with the right algorithm in terms of what that exact formula should be, but often I think about it in kind of a three-fold in terms of wins the right time, what’s the right combination, and how do we see in the drugs, and I think the sequencing is the biggest thing that we don’t yet know, and how do we combine the two different..two different drugs in a way, and how do we give them in a way that will maximize efficacy, will minimize the toxicity, so as an example is, Do we give two drugs for a specific period of time, and then after some determined time point, do we…

And change it to a different set of combination of drugs to make sure that patients are getting the most benefit of the drugs, and we don’t know that yet, but I think that that’s where the general direction…where the landscape is heading, so the activation tip I would take home from this is just to have a conversation with your physician about potential clinical trials and how combination therapies are being used.

Quizartinib in FLT3-ITD-Positive AML

Introduction 

I generally think of treatments for AML as old, meaning they were around when I was diagnosed in 1992, or new ones that were developed after that. In the first 25 or so years since I was diagnosed, there were very few new treatments. In the last 5-7 years, however, there have been several new treatments. There are targeted treatments like, Ivosidenib (which I wrote about in November: Ivosidenib and Azacitidine for IDH1-Mutated AML) as well as Ventoclax which is used with a number of different drugs (Azacitidine, Decitibine and low dose Ara C). This post is about a new (to the U.S. anyway) drug, Quizartinib, which is used in AML patients who have a specific mutation FLT3 (fms-like tyrosine kinase 3), specifically a FLT3-ITD (internal tandem duplication) mutation. 

Overview of FLT-3 

There are two different mutations in the FLT3 gene, ITD and tyrosine kinase domain mutations (TKD). The most common mutation in AML is in the FLT3 gene. About 30% of AML patients have an FlT3 mutation, with FLT3-ITD mutations more common than FLT3-TKD ones. Some of the existing drugs for FLT3 mutations treat both. Midostaurin (Rydapt) and Gilteritinib (Xospata) are used in patients with either FLT3 mutation. Quizartinib is only used to treat patients with a FLT3-ITD mutation. 

Current Study of Quizartinib 

The current study, the results of which were presented at the 2022 European Hematology Association (EHA) Annual Meeting in Vienna, tested standard chemotherapy with Quizartinib or with a placebo, followed by maintenance with Quizartinib or placebo for 3 years. More than 500 patients with a FLT3-ITD mutation were treated in the trial. Quizartinib or a placebo were added to the “7+3” standard induction therapy, which consists of 7 days of cytarabine (Ara-C) plus 3 days of daunorubicin or idarubicin. Patients who were in remission after induction either went on to up to 4 rounds of high dose cytarabine consolidation with Quizartinib or placebo and/or an allogeneic (donor) stem cell transplant, followed by up to 3 years of maintenance therapy with Quizartinib or placebo. 

The patients who received Quizartinib had a median overall survival of more than double the patients who received the placebo. Almost all patients in both arms experienced side effects of the treatment (emergent adverse events or AEs). This is not a surprise, most patients treated for AML have significant side effects. Patients who received Quizartinib had more side effects, in particular there was a higher incidence of significant neutropenia (low white counts) and more patients who received Quizartinib discontinued treatment because of adverse events. There were 56 treatment related deaths in the trial, somewhat more in those who received Quizartinib. 

Quizartinib looks like a promising treatment for FLT3-ITD AML patients. I believe that this is the only randomized (Phase III) trial that has been completed of a drug that treats mutations in the FLT-3 gene along with standard chemotherapy. It will be interesting to see how it compares to other drugs for patients with FLT-3 mutations. On the downside, it is only used for FLT3-ITD mutations, unlike Midostaurin and Gilteritinib.

Laura Beth:

Dr. Ravandi, does maintenance therapy have a role in AML?  

Dr. Ravandi:

Maintenance therapy is something that has been used in other leukemias for a long time, and other types of cancer, particularly in ontological cancers. In AML, it hasn’t been normal practice, traditionally, mainly because in AML, we haven’t had many good relatively nontoxic, easily taken drugs.  

So, about 30 years ago, some groups, for example, a German group actually tried to do maintenance with cycles of chemotherapy, and you can imagine if a patient is in remission, and somebody says to you, “I’m going to give you cycles of chemotherapy for the next three years,” most patients wouldn’t take it because they say, “Well, you know, maybe I have three years to live. I want to go to Bahamas and be on the beach rather than getting cycles of chemotherapy.” But over the last several years, in a number of effective, highly effective oral agents that have been developed, and one specific agent that has been developed for maintenance. Now, this specific agent is not curative, as it’s not that if you take it, you will live forever.  

But it does improve survival, and it’s relatively well-tolerated. And there are other clinical trials of maintenance. Agents are being developed, and I think it’s a very important area in AML. And I think in the next several years, it will actually become common practice to do maintenance regimens.  

Laura Beth:

That’s good news. So, once an AML patient is in remission how are they monitored? 

Dr. Ravandi:

So, I mean, I usually tell my patients that once you’re in remission, you’re in remission until something goes wrong with your blood counts. So, in my opinion, it’s not important to do – definitely not important to do weekly blood counts, for example.  

Depending on patient’s anxiety levels and comfort, we do check their labs maybe once a month, once every two or three months, depending on how far they are from their remission. And in my opinion, routine bone marrows are not necessary during remission, unless the patient is a part of a clinical trial that they have accepted to participated in, because we do get a lot of information by doing those bone marrows. So, some studies have follow-up bone marrows, but that’s really as a part of a clinical trial and to help further the knowledge in therapy.

Laura Beth:

When it comes to AML research and emerging treatment options, what are you excited about right now?  

Dr. Ravandi:

Well, I think one of the biggest, I would call, revolutionary changes in AML was the introduction of venetoclax (Venclexta), because AML is a disease of the older population.  

The median age is about 68, which means half of the patients are older than 68, and among the other half, majority are older than 55. And when you go beyond 60, 65, traditional chemotherapy is not well-tolerated. But the introduction of venetoclax plus azacitidine (Onureg) or decitabine (Dacogen), depending on the center, has really completely changed the management of older AML patients from a situation that it was dismal treatment to a situation that’s still not great, but it’s a lot better, as in we don’t cure the majority, but many people have a tolerable therapy and live with their disease for several months if not several years.  

And personally, I have treated a 97-year-old patient, and she did well for three years, so. Because of this drug, age is no longer as frightening as it used to be for advanced age. 

Laura Beth:

So, where do clinical trials fit in when it comes to choosing treatment?   

Dr. Ravandi:

So, the best drugs that we have available now, the venetoclax that I mentioned and all the other drugs that I mentioned, targeted drugs, came from clinical trials.  

If we don’t do clinical trials, we would be still doing the same treatments that we were doing in the 1970s and ‘80s.  

In fact, up until about seven or eight years ago, many places were still doing the same treatments that was developed in 1970s, which in the era of computers, and Apple, and everything else, it’s mindboggling that we should be doing something that we were doing in the ‘70s. So, clinical trials are important to move the field forward. They are at major academic centers, all the clinical trials are extremely well-vetted and scientifically vetted, as well as with institutional review boards, ethically vetted. So, patients can be sure that they’re not going to get anything less and potentially more than what they would normally get.

Laura Beth:

How do test results impact AML care and treatment decisions?  

Dr. Ravandi:

So, in the first place, the presence or absence of certain mutations can be predictable outcome. Some subsets of leukemias are, for the lack of a better term, more favorable.  

I personally don’t think there is anything favorable about any leukemia, but some are easier to treat, and some are easier to cure than others. There is one specific subtype called acute promyelocytic leukemia that we actually completely treat differently. We don’t use even chemotherapy in that subset of leukemia.  

It has almost 100 percent success rate. And the treatment of other subsets can also be tailored, depending on these molecular and chromosomal changes. So, the initial therapy can be actually changed. There are now, for example, targeted agents that can be added to the chemotherapy, during initial chemotherapy.  

And also, once the patient is in remission, depending on favorable or unfavorable their leukemia is, they may be offered allogeneic stem cell transplant. So, yes, this information is highly important. In fact, I would say crucial for our decision-making in leukemia therapy these days.  

Laura Beth:

So, what is new in AML research related to molecular markers?  

Dr. Ravandi:

Well, it depends on your definition of new, but FLT3 mutations are very important because they’re now several FLT3 inhibitors, and as I mentioned, the initial therapies are different, to some extent. The IDH mutations are very important, again, because they are specific targeted agents.  

TP53 mutations are important because, unfortunately, they are particularly unfavorable.  

This is completely hot off the press, but there are subsets of AML called MLL rearranged leukemias that can respond to these drugs called Menin inhibitors.  

There are other mutations that have been discovered, many other ones, that there are no specific treatments for at the moment, but there’s a lot of research on.

Does Maintenance Therapy Have a Role in AML Care


Transcript:

Laura Beth:

Dr. Ravandi, can you define molecular testing for AML patients?  

Dr. Ravandi:

We have progressed on our understanding of cancer, in general. And we have progressed in our technology, so we know that various cancers are likely caused by a number of molecular events, and this is best characterized in leukemias because we have been doing this in leukemia for many years now, simply because leukemias are much more accessible than other cancers. Leukemic cells are in blood and easily obtained and even in bone marrow, are much easier obtained than other solid tumor cancers.  

And so, we’ve been able to identify a number of gene and chromosome changes that we have discovered to be prognostic, but also, have become the targets for developing effective drugs.  

Laura Beth:

Beyond molecular testing, what other testing should take place following an AML diagnosis?  

Dr. Ravandi:

I mean, the classical patient presents because there is something in their blood counts, so they usually have had a blood count testing done. And, of course, you need to do a number of other tests, for example, the chemistry profile, because that can show us some of the problems that can be caused by leukemia.  

And the most important thing is bone marrow aspiration and biopsy, which is still, unfortunately, absolutely necessary, first to make the diagnosis, and second, to obtain the specimens for those biomarker testing that you mentioned.  

Laura Beth:

If a patient relapses, does all of this testing need to be repeated?  

Dr. Ravandi:

Unfortunately, yes. And so, when you said all of these testing, actually, again, compared to some other cancers, this is limited testing. Taking blood for the blood tests, and even doing a bone marrow is generally much easier than taking tissue in a colonoscopy for a colon cancer, or doing a biopsy, a lung biopsy in lung cancer, etc.  

But yes, they all need to be tested, and actually, we do like to repeat the genetic testing because leukemias are dynamic, and after initial therapy, they may change in ways. They may develop new targets or new molecular changes that may be potentially amenable to new targeted therapies.  

Laura Beth:

And is it common for a mutation to appear at a relapse?  

Dr. Ravandi:

It is, yes. I mean, I would say it’s – I wouldn’t say it’s common, but it is frequent.  

Ivosidenib and Azacitidine for IDH1-Mutated AML

There has been another significant advance in the treatment of Acute Myeloid Leukemia (AML) at least for the small subset of patients (6-10%) who have a mutation in one of their genes called IDH1 (isocitrate dehydrogenase 1).   

Until 5-7 years ago, the typical initial treatment (called induction) for patients with AML consisted of relatively high doses of cytarabine (Ara-C) and another chemotherapy called an anthracycline (usually either daunorubicin or idarubicin).  Cytarabine is given as a continuous infusion for seven days and a daunorubicin or idarubicin is given on the first 3 days (this is commonly referred to as “7 + 3“regimen). There are other regimens that are sometimes used although most contain cytarabine.  This regimen is effective, but quite toxic and usually reserved for healthier fitter patients (generally under 65 without comorbidities like diabetes, or certain heart conditions). 

In 2018, the Food and Drug Administration (FDA) approved venetoclax and azacitidine for use in older patients or those with comorbidities.  Earlier this year, FDA approved Iivosidenib (used in combination with azacytidine) for newly diagnosed AML patients an IDH1 mutation.  The approval was for “adults 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy”.  This was based on a clinical trial reported in the New England Journal of Medicine (NEJM): Ivosidenib and Azacitidine in IDH1-Mutated Acute Myeloid Leukemia,.  Ivosidenib is not a brand new drug, it was approved in 2018 for relapsed or refractory AML. 

The current approval was based on a global, double-blind, randomized, placebo-controlled trial comparing AML patients with an IDH1 mutation treated with ivosidenib and azacytidine with patients treated with azacytidine alone.  The primary end point of the trial was event-free survival (EFS), defined as the time until treatment failure (i.e., the patient did not have complete remission by week 24), relapse or death.  The first group of patients, who received ivosidenib had an EFS at 12 months of about 37% versus 12% in the placebo group.  In addition, the median overall survival (that is half of the patients lived at least this long) was 24.0 months with ivosidenib and azacitidine versus 7.9 months with azacitidine alone.  This is a big difference, although there is still a lot of room for improvement.  In addition, there were fewer infections in the ivosidenib, group although there were more incidences of low white blood counts (neutropenia) and bleeding in that group. 

While this is good news, showing ivosidenib (Tibsovo) and azacitidine (Vidaza) is better than azacitidine alone, most patients with AML with an IDH1 mutation who are not good candidates for intensive induction chemotherapy during the time period of the trial would likely have been treated with azacitidine and venetoclax (Venclexta).  The combination has been shown to be much more effective than azacitidine alone.  My guess is that azacitidine alone was chosen as the comparison, since the ivosidenib trial started enrolling patients in March 2018 (presumably the protocol for the trial was completed several months before that) and venetoclax was not approved until November, 2018.  The question remains, which is better ivosidenib and azacitidine or azacitidine and venetoclax.  I believe we will probably never know.  Given that AML is already a rare disease and no more that 10% of AML patients have an IDH1 mutation, it is not likely such a trial would be done.  Instead, it seems more likely that trials will look at the 3-drug combination of ivosidenib, venetoclax and azacitidine.  Perhaps a trial with 3 arms may be done, comparing azacitidine with ivosidenib, or venetoclax or both.  I hope the 3-drug combination will be more effective than either ivosidenib or venetoclax combined with azacitidine.  If the side effects are not much worse, then standard therapy for AML patients with an IDH1 mutation who are not good candidates for intensive chemotherapy would become the 3-drug combination.  This would happen faster than first comparing ivosidenib to venetoclax and then comparing the better of those two to the 3-drug combination.   For younger healthier patients, ivosidenib is being combined with intensive chemotherapy in clinical trials.

Katherine Banwell:

Why is it essential for patients to share any issues they may be having with their healthcare team, specifically, sharing their symptoms and side effects?   

Dr. Eytan Stein:

Well, it’s important because we want to help you. I mean, I think that’s what it comes down to. All of us, whether it’s your doctor or your nurses or your nurse practitioner or physician’s assistant or anyone who is part of the healthcare system, we went into this business to help people. I mean, we knew what we were getting into when we went into this, and we want to help people. And one of the ways you help people is you help with their symptoms. So, if you’re not feeling well, you call up, and you say, “I’m not feeling well,” we can help you with that. You shouldn’t suffer in silence.  

I sometimes have patients who will say to me, “Oh, I was going to call you, but I didn’t want to bother you.” You’re not bothering us. This is what – it’s not like you’re calling and asking for mortgage advice, right? This is what we do. So, it’s very important to call us because the other thing is that you’re going to be more – it’s more likely that you’ll be able to complete your treatment if we manage the side effects that you’re having rather than just ignoring them.  

Katherine Banwell:

What advice do you have for patients to help them feel confident in speaking up and becoming a partner in their own care? 

Dr. Eytan Stein:

My advice is, speak up. You just speak up. It’s very important. It’s your – you know, at the end of the day, this is a disease that you are experiencing. Your doctor is there to partner with you and to guide you, but it’s your body. It’s your disease, and you need to be very vocal in what you’re experiencing and advocate for yourself.  

Katherine Banwell:

If a patient has difficulty voicing their questions or concerns, are there members of the support staff who could help?  

Dr. Eytan Stein:

Most centers have a social worker on staff that can help them out. I highly, highly encourage all of my patients to meet with a therapist or a psychologist that specializes in taking care of patients with cancer. I have become more vocal about this that I see really, it’s probably the best thing a patient can do for themselves, and there’s no downside. If you don’t like it, you don’t have to go back. You can do one appointment and not go back. But that can be extremely helpful, extremely helpful.  

So, it’s important in both ways. You need to alert your doctor that you might be feeling one way, but I think it’s also on the doctor to sort of take visual cues from the patient when they see them to understand what they might need and to make those kind of recommendations.  

Katherine Banwell:

Yeah. As we close out our conversation, Dr. Stein, I wanted to get your take on the future of AML. What makes you hopeful?  

Dr. Eytan Stein:

Oh, so many things make me hopeful. I mean, we understand this disease so much more than we understood it even 10 years ago. There are all sorts of new treatments that are being developed. We’re improving the survival of our patients with the new treatments that have already been approved over the past 10 years. And I really think the golden age of AML treatment is upon us, and I really think that – and some people might think I’m crazy – but I really think that by the time I’m done with this, you know, one day, I’ll get too old, and I’ll decide I need to go retire and spend time with my family. But I think by that time, we’re going to be curing the vast majority of our patients. 

Katherine Banwell:

That’s so positive. It’s great to hear that there’s been so much advancement and that there’s so much hope out there for AML patients.  

I want to thank you so much for taking the time to join us today, Dr. Stein.  

Dr. Eytan Stein:

Okay, thank you. It was really nice to be here.

Katherine Banwell:

With more oral therapies becoming available, patients now have a role in self-administering their treatment. So, what happens if a patient forgets to take a medication? Does that impact its effectiveness? 

Dr. Eytan Stein:

The easy answer to that question is probably not. You know, if you forget to take a medication for three weeks, that’s not a good thing, but if there’s a – you know, this happens all the time, right?  

You’re busy, and you just forget. If you forget to take a medication one night or one day, it almost certainly is not going to make a huge difference. Having said that, you shouldn’t see that as license to not be careful. So, it is important to try. So, set an alarm; put out a pill container do the kinds of things that can help you.  

The other thing, there is a certain what I would call pill fatigue that sets in. Often, patients with AML are taking multiple medications at multiple times a day, and it can be hard. And at my center, we have pharmacists who do a lot of different things, but one of the things they can help with is sort of streamlining patients’ pill burden to make it easier for them to remember and to take the medications when they’re supposed to take them. 

Katherine Banwell:

When a patient does forget to take a dose or even a couple of days’ doses, should they call their healthcare team and let them know? 

Dr. Eytan Stein:

Yes, always call. Always call.

Katherine Banwell:

Once treatment has begun, Dr. Stein, how do you know if it’s working?  

Dr. Eytan Stein:

So, that’s a good question. So, the good thing about acute myeloid leukemia when it comes to understanding what’s going on, you know, it’s a disease of the bone marrow cells. And we do bone marrow biopsies to see how things are doing. But no one likes a bone marrow biopsy. It can be a somewhat uncomfortable procedure.  

Katherine Banwell:

How often would a patient need to have a biopsy? 

Dr. Eytan Stein:

Yeah, so they have bone marrow biopsies at diagnosis, and then they often will have bone marrow biopsies two weeks to a month later.  

And then, if they’re in remission, basically any time you think if you want to check to see if they’re in remission or if you suspect the patient is relapsing. Then, you would do a bone marrow biopsy. But what I was getting at is that but you have blood. And the blood is kind of like the bellwether of what’s going on in the bone marrow.  

So, the analogy I use for my patients is, you know, when you’re driving your car and you have – you know, you don’t open the hood every day to make sure the car is running okay. You know, you’re driving your car, and if your car starts making a funny clinking sound, that’s when you open the hood.  

So, the blood is like the clinking sound. If you see something going wrong in the blood, that’s when you know you’ve got to open the hood and look under the hood. If the car is running just fine and you don’t see anything wrong in the blood, using the analogy, maybe you don’t need to do a bone marrow biopsy. 

Katherine Banwell:

What if a treatment isn’t working? What if it stops working or if the patient relapses? What do you do then? 

Dr. Eytan Stein:

Yeah, so when a patient relapses, which unfortunately happens more than we want it to, it’s important number one to do another bone marrow biopsy and at that point, do that mutational testing again because the mutations that are present at the time of diagnosis are not necessarily going to be present at the time of relapse, and sometimes, a new mutation might occur at the time of relapse.  

And again, what that mutational profile shows can help determine what the next best treatment for the patient is. There might be standard-of-care therapies. More chemotherapy might be recommended.  

When a patient relapses, I usually – excuse me – try to get them on a clinical trial because that’s the point where I think clinical trial drugs really have potentially major benefit for the patients, to help get them back into remission. 

How Do Gene Mutations Affect AML Treatment Choices?

Katherine Banwell:

Why is identification of genetic markers essential before choosing treatment?  

Dr. Eytan Stein:

Because when you know the genetic markers, you can target the genetic abnormalities, sometimes with specific targeted therapies, with therapies that fit like a key in a specific lock.  

And those targeted therapies have been shown, in some cases, to improve the survival of the patients, without much cost, without much toxicity. So, I’ll give you an example of this.  

There is a very common genetic abnormality in patients with acute myeloid leukemia called the FLT3 or FLT3 mutation. When you have that mutation, there is a targeted therapy that targets the FLT3 mutation called midostaurin (Rydapt), and it’s been shown in a very large clinical trial that the addition of the targeted FLT3 inhibitor midostaurin in combination with chemotherapy leads to better overall survival than chemotherapy alone.  

So, you need to know that information because you want to give your patient the best chance at beating the disease. And that’s why it’s also important to try to get this information back quickly. You know, no one wants to be sitting around waiting for four weeks to find out if they’ve got a specific mutation. And we’ve gotten better. I think medical centers generally have gotten better at getting this mutational information back to their doctors relatively quickly. 

Katherine Banwell:

Does every patient get this standard testing? 

Dr. Eytan Stein:

It is – does everyone get it? I don’t know. But “Should everyone get it?” is, I think, the important question. Yes, everyone should get this testing.  

It is incorporated into the NCCN and National Comprehensive Cancer Network and European Leukemia Net guidelines. It is important not only because you can think about targeted therapies, but it is also important for prognostic reasons, meaning that certain mutations lead to a higher risk of relapse, and those mutations in a patient might lead me to recommend a stem cell transplant, which is sort of the most intensive thing we can do to help prevent a relapse, while other mutations, which might be “favorable”, in quotes, they might lead me not to recommend a stem cell transplant.  

So, I think this mutational testing is the standard of care and should be done in every patient with newly diagnosed acute myeloid leukemia.

Katherine Banwell:

All patients are different, of course, and what might work for one person might not be appropriate for another. How do you choose which treatment is right for a patient? 

Dr. Eytan Stein:

So, it’s an individualized decision. So, what you’re talking to the patient, as we talked about at the very beginning, is you really need to understand the patient’s goals for treatment. You need to understand the anticipated benefit of the treatment that you’re offering and need to understand the side effects of the treatment. 

So, and that sort of becomes the puzzle that you work with the patient at putting together. That is how well do I expect this treatment to work? What are the potential side effects of the treatment, and what are the patient’s goals? And when you sort of lay all those different pieces out, you then usually come up with something that becomes pretty clear what the best thing to do is.  

So, I’ll give you just a very concrete example of this. Sometimes, we have treatments where the medical data would suggest that they might work as well as one another, right? There’s no clear difference between each of the two treatments. But maybe one of the two treatments requires you to be in the hospital, and one of the treatments allows you to be at home.  

So, that’s an important discussion to have with the patient because some patients, believe it or not, want to be in the hospital, because they’re worried about being at home and having to manage this all themselves. Some patients don’t want to be in the hospital. Some patients want to be at home, because they’re scared of the hospital, or they’re worried the food’s going to be terrible.  

And then, that would be important in helping the patient make the decision for their treatment. 

Katherine Banwell:

Right. You mentioned earlier, Dr. Stein, the difference in ages and how you would treat different people depending on their age. So, when you’re choosing a treatment, you obviously look at age. What else? Things like comorbidities? 

Dr. Eytan Stein:

Yeah, so age, so I’m not ageist. So, it’s more that as people get older – and this is just a fact of life – as everyone gets older, their organs don’t work quite as well anymore, right? Things start breaking down as you get older. So, certain treatments aren’t appropriate for older people because the treatments a younger person, because their organs are working at 100 percent, may be able to handle it, while an older person, where their organs might only be working at 60, 70 percent, the treatment might not be as good of a choice for them. 

So, that’s what I mean. So, as people age, their comorbidities increase. So, we always look at comorbidities, and if you had an 80-year-old that was running marathons, I might think about their treatment differently than an 80-year-old who is not running marathons. But most 80- and 85-year-olds aren’t running marathons, so that’s why we sometimes think about their treatment differently.
