Dr. Daver, what treatment strategies are available for high-risk AML patients?

Dr. Naval Daver:

High-risk AML patients includes a group of a number of different mutations, and cytogenetic abnormalities, this includes TP53 mutation, as well as adverse cytogenetics, which includes chromosome 17, deletion 5, deletion 7, as well as complex carrier type. This entire group historically had a poor outcome and has had limited responses to traditional intensive chemo, even if we achieve responses there, usually short-lived.

We do have some patients where we are able to achieve remission with intensive chemo or with azacitidine-venetoclax (Vidaza-Venclexta) and transition and transmission them transplant with about 25 to 30 percent potentially achieving a long-term remission and possible cure. 

But aside from that, there is very little potential to cure these patients with just traditional intensive chemo, venetoclax in this area, there has been developments with the emergence new class of immunotherapy drugs, called CD47 antibodies, the one that’s most advanced in this field is a drug called magrolimab, and we are evaluating the drugs such as magrolimab in combination with azacitidine as well as in combination with azacitidine-venetoclax and are seeing high remission rates, both in TP53 mutated and TP53 wild type.

So this pathway that works by activating a macrophages or the immune system to attack the tumor cells, seems to be in some way mutation agnostic with response rates being maintained even in the traditional high-risk subsets, especially such as TP53 and complex cytogenetics for some of the other high-risk groups such as MLL, we’re using targeted therapies like menin inhibitors, and these seem to work well in those patients who have these adverse cytogenetic molecular abnormalities, so there is progress, and we think that the CD47 antibody field and hopefully the main inhibitor feed will be able to improve outcomes in these traditionally molecular cytogenetic subsets.

My activation point related to this question is for high-risk mutations and cytogenetic commonalities such as TP53 complex carrier chromosome 17 MLL,  best hope at this time is in clinical trials evaluating novel therapies such as CD47 antibodies and menin inhibitors. These are not yet FDA-approved, but based on emerging data from the ongoing Phase I, II studies, we think that there is a good chance they will be approved in the future.

However, this time, the best way to get up to these agents is to go on clinical trials and incorporate these therapies, both in the frontline setting as well as in the relapsed refractory setting.

Dr. Daver, what is a menin pathway in AML? And why is it significant?

Dr. Naval Daver:

The menin pathway is very recently discussed that way, the pathway, of course, itself has been known for almost a decade, this is an epigenetic pathway, and in certain subsets of AML such as MLL rearranged NPM1 mutated as well as other fusions, we find that there is an up regulation of the menin impact rearrangement, and this actually results in increased production of two enzymes called meis-1 and hox-DNA) these enzymes actually result in a differentiation blockade. So normally, in the bone marrow we have the early progenitor cells, this then leads to be a report cell and leads to mature neutrophils and monocytes and blood cells, but in a differentiation blockade, we would see that those cells over time would start generating mutations and become leukemic cells.

So one of the most physiological ways to treat AML is to actually remove the differentiation blockade, so the normal process of differentiation with progress, and so these menin inhibitors are able to reduce the levels of MEIS1 and HOXA by doing this, they allow the normal differentiation cascade to progress, and they’re not cytotoxic targeted chemo, they’re not directly killing leukemia, but they’re actually allowing the leukemia itself to then mature to no monocytes and neutrophils.

And so now there are five different menin inhibitors in ongoing clinical trials, but two of these are more advanced and have shown data recently in the ASH 2022 meeting the newer drugs, and are showing close to 40 to 50 percent single agent efficacy, and we believe that after the FLT3, IDH1, IDH2 inhibitors, which have been approved in the last five years, the menin inhibitors are probably the next other targeted therapies that will hopefully get approval and they eventually be used in the frontline setting in combination approaches. 

The activation tip related to this question is that patients should be checked for arrangements like MLL rearrangement NPM1 mutation, new fusions as these may be amenable to therapy with the menin inhibitors, there are multiple trials with five different menin inhibitors, single agent trials and also combination trials now ongoing across multiple centers both in the U.S. and ex-U.S., and if one does have an aberration that will be sensitive to such menin inhibitor-based therapy, I would strongly recommend considering trying to get on one of those trials because we believe that these will be the best outcomes with such standard therapies rather than using the standard or traditional chemotherapies.

Dr. Daver, for AML with a FLT3 mutation, what have we learned, and what is currently being investigated?

Dr. Naval Daver:

AML with the FLT3 mutation is very important from both prognostic and from therapy perspective, prognostically, this is considered to be one of the high-risk mutations, it’s also one of the most frequent mutations in AML in, seen in about 30 to 35 percent of younger and about 15 to 20 percent of older patients with AML, and these patients often have very prolific disease, elevated white count leukocytosis. And without the addition of FLT3 inhibitors, there is a high risk of relapse and a short overall survival. 

Over the last 15 years, a number of targeted therapies called the FLT3 inhibitors have emerged, these started with the first-generation FLT3 inhibitors drugs, such as lestaurtinib and sorafenib (Nexavar), now we have the second-generation FLT3 inhibitors, this includes drugs like gilteritinib (Xospata), quizartinib, and crenolanib which are more potent, specific, and better tolerated.

The first study that showed that the incorporation of FLT3 inhibitors improves outcome was a study called RATIFY Study, this is a frontline study looking at newly diagnosed FLT3 mutated younger patients where we added the FLT3 inhibitor midostaurin (Rydapt or Tauritmo), which is the first-generation FLT3 inhibitor to the standard induction chemo versus a placebo, added to standard induction chemo, induction chemo being standard of care to that time and this showed that in the addition of FLT3 inhibitor to induction chemo did improve remission rates and overall survival as compared to induction, and led to the approval of the FLT3 inhibitor midostaurin in the frontline setting. 

Since then, two other FLT3 inhibitors, second-generation potent FLT3 inhibitors drugs called gilteritinib, and lestaurtinib have also been evaluated. Gilteritinib, in a relapsed setting where single-agent gilteritinib, has given 50 to 60 percent response rates and has been extremely well-tolerated and much better than any other salvage treatment in the FLT3 space that we have ever seen, and in the frontline setting quizartinib and second-generation inhibitor also very recently, just a few months ago, there was data showing the combination of his art with intensive chemotherapy improved survival as compared to intensive chemotherapy alone. 

And so we think we are…they will be a third for the inhibitor to get approved, so there’s been a lot of progress overall in the three space, and there are other newer FLT3 inhibitors also in early clinical investigation that we think could eventually be as part or even better, the activation point related to this question is that, for the inhibitors have dramatically improved outcomes, both in the frontline setting when added to traditional backbone intensive chemotherapy as well as potentially lower intensity therapy, as well as in the relapsed refractory setting, and it is very important to know the status of the FLT3 the mutation, both in diagnosis to see if one would benefit by the addition of the FLT3 inhibitor to the frontline induction chemo as well as in relapse because this would open up the option for FLT3  inhibitor targeted therapies, which would probably have the best chance of response and long-term outcomes.

How Can We Address Disparities in AML Among Diverse Populations

Transcript: 

Art:

Dr. Daver, what are the different subtypes of AML, are various subtypes more prevalent in certain demographics?

Dr. Naval Daver:

The main way we have classified AML has actually been changing, so when we talk about subtypes  there are actually two different classification systems like WHO and the ICC or ELM classification system. Traditionally, we have been using the ELM for prognostic classification of AML, this divides patients into three major buckets, what we call a favorable intermediate and adverse, and these are based on the underlying chromosome cytogenetics abnormalities and molecular or next-generation sequencing profile of the patients.

In general, in AML there has actually been limited data and publications regarding the demographic distribution, whether it’s regional or racial or cultural, one of the things that we do know, for example, in acute lymphoblastic leukemia is that in the Hispanic population, there seems to be higher frequency of things like FLT3-positive ALL. 

But in the AML population, there actually does not seem to be, at least based on published data, huge differences in the molecular or cytogenetic presentation. We have seen some data from different countries that there may be a difference in the prevalence of communications across different regions. For example, in Japan, we do see that the incidence of FLT3 and NPM1 appears to be lower than what has been reported in the United States.

Also, we see in Europe and United States, the incidence of these mutations with FLT3, NPM1 is similar, and then we are seeing in some of the larger academic centers in the U.S., there is an enrichment of referral of patients with TP53, which is very adverse and most difficult to treat mutation, and a lot of that we think is because patients with solid tumors and with other hematological malignancies are surviving longer with the CAR-T therapies, immunotherapies, and because it is over time, they have a risk of developing second AML, which is enriched for TP53 mutation, so we do see over the last two decades that from TP53, which used to be about 5 percent to 10 percent, is now up to 20 percent to 25 percent of AML and growing in proportion because it’s better survival and solid tumors and lymphomas.  

The activation tip related to this question is that in general, they don’t review discrepancies based on geography and race, and region in the molecular cytogenetics. However, we do see differences in patients who have received prior chemotherapy, radiation therapy, AML therapy for other solid tumors and lymphoma.

These patients, when they transformed what we call secondary AML or MDS, seemed to have a higher predilection for certain high-risk communications such as TP53, and these are best treated with ongoing frontline clinical trials at large academic centers.

Art: 

Dr. Daver, for older and high-risk AML patients, how are the treatment approaches expanding?

Dr. Naval Daver: 

In older and high-risk AML, the major approval has been the combination of azacitidine (Onureg or Vidaza) and venetoclax (Venclexta), which is a BCL-2 inhibitor, the regimen was evaluated in a large Phase III study called the VIALE study, where we looked at the standard of care for the last two decades for older unfit AML, which azacitidine alone versus the combination of azacitidine and venetoclax and this combination showed a three times higher remission rate, 75 versus 28 percent overall remission rate as well as an improvement in overall survival and long-term survivors.

So this has led to great progress with now remission rates of 75 percent achievable in older unfit AML and many of them being durable at three years with ongoing follow-up, so this has really opened the door for us to be able to treat patients up to 75, 80, 85 years of age with effective therapy given the three parts of these to achieve remission, which is usually associated with freedom from transfusion improvement, quality of life, improved energy, less time in the hospital, less infections.

The other progress now is coming from the use of targeted therapies as well in these populations, and even though the HMA venetoclax or azacitidine combination is doing very well.

We now have data, in fact, from the ASH 2022 December meeting that at three years, about 25 percent or so I would still remain alive with azacitidine was even or 8 percent, now it’s 25 percent. But, of course, we want to do much better than that, and so this is where we are incorporating the targeted therapies, the FLT3 inhibitors, the IDH1, IDH2 inhibitors, menin inhibitors, and immunotherapies onto the backbone of azacitidine-venetoclax, which we hope will further improve that long-term survival cure from 25 to hopefully 50 to 60 percent and beyond.

So a lot of progress, you know, going from less than 10 percent, a 30 percent survival, long-term, and I think in the next few years, even up to 50 percent with some of these new combinations. The activation tip related to this question is that there is a dramatic progress, especially in the treatment of older unfit AML with the approval of the azacitidine-venetoclax combination.

This regimen is now giving high remission rates, which approximate remission rates that are seen with traditional intensive chemotherapy without the mucositis and toxicities and better volatility, and we are now working to further improve the remission and the durability of this dominant of initial.

 …potentially adding targeted therapy such as FLT3 inhibitors, IDH1, IDH2 menin inhibitors, and we think that potentially in the next decade, we could be achieving long-term cures in a large proportion of older unfit AML, which was something one could just dream of a decade ago.

Dr. Daver, for newly diagnosed AML patients, what are the latest and most promising available therapies?

Dr. Daver:

For newly diagnosed AML at this time, the most promising agents include targeted therapies and BCL-2 inhibitor treatments, these are non-chemotherapeutic drugs, and we’ve seen great progress in the application of these as well as recent FDA approvals.

So one of these is an agent called venetoclax (Venclexta), which is a BCL-2 inhibitor and venetoclax in combination with hypomethylating agents such as azacitidine (Onureg or Vidaza) has shown a response to close to 75 percent. 

And the nice thing is that this regimen can be given and patients who are older than 70, 75 years of age, and even those who are having comorbidities are not fit for traditional intensive chemotherapy with similar response rates, so this has been approved in the last couple of years for the frontline treatment of AML, and we’ve been using this combination of venetoclax and azacitidine quite frequently with high efficacy in this patient population, the other new agents that have shown breakthroughs in AML are the targeted therapies, these include FLT3 inhibitors that target the FLT3 mutation and these have shown good activity, but the single agents with gilteritinib (Xospata) being approved in the relapsed refractory setting as a single agent where gilteritinib showed a response rate of about 50 percent as a single oral targeted therapy in relapsed FLT3-mutated AML, which is actually better than the response rate with high-dose combination more where the response rate is only about 25 to 30 percent.

So, gilteritinib is now approved, and it’s now moving and being evaluated in frontline setting other FLT3 inhibitors like lestaurtinib (CEP-701), actually just recently completed frontline studies showing improved outcome when lestaurtinib added to intensive chemo versus just intensive chemo in FLT3 in AML. And we hope and think there’s a good chance lestaurtinib will be approved in the near future.

And also IDH inhibitors have been approved both in the relapsed setting, frontline setting, and now we even have a third group of targeted therapy is called the menin inhibitors, they target MLL rearrangement and NPM1 mutations, which are seen in about 15 percent to 20 percent of the AML, so there’s been a lot of progress.

All of this in the last seven years, six, seven years with multiple targeted therapies, with multiple inhibitor-based treatments, showing progress in AML and then also recently, the concept of maintenance therapy, this is something we used for the last couple of decades in a acute lymphoblastic leukemia and multiple myeloma and in lymphoma.

But we had not had clear data in AML, but the recent study using oral formulation of a azacitidine in CC486 has shown the maintenance in patients who complete an induction consolidation and could not go to allogeneic stem cell transplant for one reason or the other was important and improve both overall survival and relapse-free survival, and so this is the first time now we have an FDA-approved and standard use of maintenance therapy after the traditional induction consolidation, so even changing the general paradigm of AML therapy.

So a lot has changed in the last seven to eight years in the treatment of acute myeloid leukemia, and this is very exciting.

And the activation tip related, this question is that there are multiple new targeted and low intensity therapeutic options available for patients with acute myeloid leukemia, and in our institution, in my opinion, even older patients are eligible for some form of therapy or the other…very few patients, if any, today, are being sent to hospitals or palliative care without treatment.

So it’s very important to really consider all the available treatment options and if needed to seek consultation with an expert or academic center to get the most up-to-date treatments available for AML.

Dr. Lai, how can we address disparities in AML among diverse populations?

Dr. Catherine Lai:

So this is an extremely important topic. And there was a large study that was recently published out of Chicago that looked at the different hospitals in the area and to look at ethnic disparities between white and Black populations and did find significant differences. Unfortunately, I would say that there are many factors that go into this, and a large portion of it is education and resources, and so what I would say is that we…we need to, as physicians and also the community, be better about educating our patients and being able to have access to resources so that everybody can get the same treatment.

And so involving other societies who support cancer to just get the word out that we need to…that we need to be aware of the differences so that we can address them specifically and make sure that for patients who don’t have resources that we are able to provide for them. So the activation tip here is that asking about resources, but we use a lot of Leukemia & Lymphoma Society grants that help our patients get access to and lower the cost of drugs, but also will…they will also provide grants just to help with cost of living, occasionally, there are other societies that can help with ride shares, and so I think even if you don’t know the specific…the specific society that can help, just asking to speak with your social worker, is there a resource that I can tap into that can help her help me with my care so that I can make sure that I can get the best access?

Dr. Lai, I was diagnosed with lots more than 20 years after my transplant, and there are the long-term effects that AML patients should be aware of. What are some of those effects?

Dr. Catherine Lai:

Yeah, so that’s an extremely important question and one that is often, often overlooked, unfortunately, even just from a time constraint perspective, but I would say it depends on the type of chemotherapy and the type of transplant, whether it was myeloablative you received radiation before your transplant, but, in general, I mean things to consider or just think about, it’s a big work, and so about your heart, your lungs, your thyroid, your kidneys, and also age-appropriate cancer screening as all things that need to be taken into consideration as late effects, if you are able to…if you’re able to find a cancer center with a survivorship clinic, I think that that’s an extremely valuable resource, because not only are they able to address these medical issues, but they’re also able to address the psychosocial component as well, and just overall general well-being.

And so I think just being aware of the fact that there are late effects and the activation tip being, is that to make sure that you’re reporting all your symptoms, however small that they may be at your appointment, so it can be discussed in asking if it might be related to a late effect, and then also asking if there is a survivorship clinic or a program that you can be a part of.

Dr. Lai, what are some of the clinical predictors for relapse in AML patients?

Dr. Catherine Lai:

So, in general, predictors of relapse, some of it depends on what risk category you’re in, so whether or not you’re favorable, intermediate, or adverse risk of the adverse risk patients are more likely to relapse once in complete remission. The other thing, what I would say is that which mutations are present, a diagnosis is a good…also a good way to track and follow disease.

So if you have a specific mutation is to be able to follow that and to be able to quantify it on testing, and then be able to track to see if that increases over time as a predictor of relapse, I would say that, in general, minimal residual disease testing and these predictors or other blood-based markers are not standards.

So a lot of this is novel and is still not standard of care yet, so the activation to here is to just have a conversation with your provider about mutations, and do you as a patient have a specific mutation that can be…that can be tracked and also specifically what risk group on my end, what risk group am I in, because that also gives some insight as to your risk of relapse.

Dr. Lai, I had a transplant almost 30 years ago for relapsed AML and was not given intensive chemotherapy to get me into remission before the transplant. What are the takeaways from the ASH 2022 meeting? Is less more when treating AML?

Dr. Catherine Lai:

Sorry, that’s a great question, and what I just like to say that it’s so great that you are doing so well, so many years after, as you know, transplant is the original form of immunotherapy and is still the only potential cure for AML. And so with that being said, with at ASH what was seen was, I think a handful of things, so what I would say is that different combinations of drugs being used, so things looking at either at novel doubles and or triplets. Meaning combinations of two or three different drugs and how toxicity is affected, there are other also novel immunotherapies that are out there, not have been as groundbreaking as transplant, and I think that there is some way to harness the immune system to make treatment more effective, we just haven’t found that. Right, chemotherapy.

And then specifically, there was a large study, a large European study that was presented as the plenary session at ASH that talked about the role of chemotherapy before transplant. And what I would say, just speaking in general, is that the new immune system that a patient gets when they get a transplant takes…the new immune system, when a patient gets a transplant, it takes some time to take over, and that new immune system is able to fight off the leukemia, and so if a patient has a slow-growing leukemia, they might not need as much chemotherapy before the transplant, because the rate at which the leukemia will grow and won’t overburden the body before the new immune system takes over.

So I think that study was very provocative and gave some insight, but I still don’t think we have the complete right answer as to what chemotherapy should be used before transplant, I think that’s really tailored to each individual patient.

And then whether or not patients need chemotherapy after transplant also depends on disease burden and status, and taking into account measurable residual disease as well. So I would say the activation tip from the ASH 2022 meeting was that there are a lot of new, exciting therapies that are coming out, and that it’s really novel sequencing strategies and combinations that I think will be the future of AML.

Dr. Lai, what does transfusion burden mean in AML?

Dr. Catherine Lai:

Yeah, so transfusion burden is the amount of either patients’ blood that you have to receive and or platelets that you have to receive.

So when we say that somebody is transfusion-dependent, that means that they on their weekly blood checks or having to receive transfusions multiple times, whether it be twice a week or once a week, but somebody who cannot make enough blood and our platelets on their own to stay within a safe range and that they need to receive transfusions. 

Typically. now, this is again specific for an individual patient, but in general, most centers use parameters such as the hemoglobin less than 7, in which they get transfused red blood cells and a platelet count less than 10,000 for platelet counts, assuming that patients are feeling well and are healthy and they’re not bleeding.

So here the activation tip would be to discuss how frequently transfusions are needed and how long you may be able to go without needing a blood or platelet transfusion with your physician.

Okay, Dr. Lai, what are we learning about patients with untreated AML who are ineligible for intensive chemotherapy?

Dr. Catherine Lai:

To define ineligible for intensive chemotherapy, I think that that is a moving target because historically, we would define patients as eligible for intensive or less intensive chemotherapy based on an age cut-off. And as the population is becoming more fit and is also getting older, what I would like to say is that we should use physiologic age, not chronologic age to determine who is eligible for intensive chemotherapy, and that is…in terms of how that is assessed, that is not uniformly done. 

But, in general, it takes into account how active a patient is and what they’re able to do on a day-to-day basis, so mostly their physical function, we also take into consideration their cognitive function as well, but to a lesser extent.

So, for patients who are ineligible for intensive chemotherapy, the standard practice would be the combination of azacitidine (Onureg or Vidaza) or decitabine (Dacogen), both of which are hypomethylating agents in combination with venetoclax (Venclexta), and that combination has really changed the landscape in terms of how we treat patients, it can be given as an outpatient, so it’s much better tolerated and has fewer side effects compared to intensive chemotherapy.

So the activation tip here is to talk with your physician about how they will determine whether or not you are fit or unfit for intensive chemotherapy.

What AML Treatment Options Are Available for MRD-Positive Patients?

What AML Treatment Options Are Available for MRD-Positive Patients? from Patient Empowerment Network on Vimeo.

For acute myeloid leukemia (AML) patients who are MRD-positive, what treatment options are available? Dr. Catherine Lai from Penn Medicine discusses MRD-positive concerns. Learn about recent guideline updates for MRD-positive and genetically adverse patients and key questions to ask your care provider. 

[ACT]IVATION TIP from Dr. Lai: For genetically adverse risk, it would be to have a conversation about whether or not you should be going to transplant. And for MRD-positive patients, I would say is to ask about how frequently my testing should be done to monitor for MRD, MRD-positive disease.

Okay, Dr. Lai, what treatment strategies are available for genetically adverse risk patients, as well as measurable residual disease or MRD-positive AML patients?

Dr. Catherine Lai:

Yeah, so I’ll take those two separately. So for the genetically adverse patients, and so just also as an update in 2020, in the summer of 2022, both the World Health Organization and the European Leukemia Network, they both updated their guidelines. So it’s called WHO 2022 and ELN 2022 in terms of how we help prognostic and risk-stratify our patients.

And so for the ELN 2022, there are a handful of additional mutations that do put patients at adverse risk, and so it would be good just to know to bring up with your physician, which in risk category am I in? 

And so in general, for the adverse risk patients, the long-term goal is bone marrow transplant once in complete remission. And so I would say that the initial treatment hasn’t really changed, but we are recommending more patients for transplant because there are a larger number of patients who are now in that adverse risk category.

For the MRD-positive patients, there are clinical trials that are targeted, are enrolling specifically for MRD-positive patients for the most part, once you’re in complete remission, if you’re MRD-positive, you just would continue on your current therapy. And for some patients who continue their current therapy that MRD, that MRD will eventually go away.

If they are done with therapy, it would be something that you would want to monitor very closely, and at the site at the time at which that that MRD is growing, you would want to consider re-initiating treatment, although that is not standard, so it’s a very tailored and individual discussion with your physician.

So, I say, in general, the activation tips for genetically adverse risk, it would be to have a conversation about whether or not you should be going to transplant. And for MRD-positive patients, I would say is to ask about how frequently my testing should be done to monitor for MRD, MRD-positive disease.

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.
