Combination AML Therapy for Newly Diagnosed Patients | What Are the Long-Term Effects?

Combination AML Therapy for Newly Diagnosed Patients | What Are the Long-Term Effects? from Patient Empowerment Network on Vimeo.

A Patient Empowerment Network community member wants to know the length of time that patients can stay on the combined treatment of azacitidine (Vidaza) and venetoclax (Venclexta). AML specialist Dr. Jacqueline Garcia responds, sharing an update on the long-term follow-up data for this combination treatment.

Jerry had this question. “How long can patients stay on azacitidine (Vidaza) and venetoclax (Venclexta) before relapse or toxicities force them to abandon treatment?”  

Dr. Jacqueline Garcia:

So, this is a good question. I would say azacitidine and venetoclax just got FDA-approved just shy of five years now, and it’s totally changed our treatment paradigm in many great ways. It was initially approved for patients that could not get intensive chemotherapies or were above 75. We call these our older patients, our more vulnerable.   

And we demonstrated and compared to azacitidine alone. It was given with placebo. We saw that the combination of azacitidine and venetoclax not only was safe, well-tolerated, it led to two-and-a-half times higher complete remission rates and impressively longer survival. That’s all we care about, patients are living longer. So, one of the things that we are appreciating in 2023 now, now that we have more patients on azacitidine and venetoclax, is that we have many patients that are long-term responders.  

So, in the original clinical trial we’ve been reported – and we just submitted the update for the long-term follow-up that we presented at the American Society of Hematology meeting in 2022, in December.   

We presented the long-term follow-up data that shows that responses can be durable and even as long as two years or three years in some patients. The average amount of time the patients are on therapy is somewhere between one-and-a-half to two years. But not every patient performs like an average patient.  

We have some that respond for less time. We have some that respond for a longer time. So, I definitely have a few patients that have been on combination therapy, and we’ve gone to year three, then four, and two that got to year five. And that was using the original indication of older the 75, no intensive chemotherapy. Most of those patients in the original trial and led to the approval were not transplant candidates. But once those drugs got approved, more patients that were older started getting this therapy.  

And so, the durability of this treatment might be longer for people that don’t have competing health problems and for specific mutation subtypes. There are a couple of mutation subtypes that include IDH2 and NPM1, where we’ve seen some extreme long-term responders.  

And then, there are others that are much shorter. So, I would say it’s very individual. In terms of toxicities in general, the regimens very well-tolerated. And if it’s not, often it’s because there should be supportive care, prophylaxis, and adjustments to the dosing strategy, which has been well-published. Sometimes, if you have a treating oncologist that is less familiar, they won’t know the nuances of how to adjust the doses, so I would ask your local oncologist to reach out to anybody that was part of the original trials. Often, a lot of us are very responsive to helping out our colleagues to help patients to stay on treatment.   

But at the end of the day, if a patient loses response or has a bad toxicity that makes it very difficult, we have to move on to another therapy.   

New and Emerging AML Therapies Being Studied in Clinical Trials

Are there newer AML treatments that patients should know about? AML researcher Dr. Jacqueline Garcia discusses therapies being studied and how recent clinical trials have advanced care for patients.

Combination AML Therapy for Newly Diagnosed Patients | What Are the Long-Term Effects

Katherine Banwell:

As a researcher, Dr. Garcia, you’re on the frontlines of AML treatment. Are there new and emerging therapies that patients should be aware of?  

Dr. Jacqueline Garcia:

Yeah. I think we’re at this really exciting point now where we had for a long time just been giving people standard two agent intensive chemotherapy. We have been studying in Phase II and Phase III settings, and even in Phase I – which means testing safety out for the first time. We’ve been moving a lot of treatments to more mature settings where we’re testing the addition of a third drug. So, for people that are getting intensive chemo, we’re looking at, “Can we add a pill to augment responses deep in them to reduce risk of disease returning?”  

For less intensive chemotherapies, one of the most common regimens we now use is something called azacitidine (Vidaza), which is a hypomethylating agent that is given by IV or subcutaneous administration. Plus, a pill called venetoclax (Venclexta).  

We helped to get that FDA-approved a couple of years ago. That combination of therapy, we call that a doublet, meaning it’s two drugs – because it’s so well-tolerated and active, we’re now asking the greedy question of, “Well, can we make it more active for patients since we’re seeing how well-tolerated it is?”  

So, there have been a lot of therapies that are currently under investigation that are adding a third drug to these less-intensive doublets. So, there’s a lot of therapies under investigation to test, “Can we add an immunotherapy target? Is there another pill that we can add? Is there another targeting mutation to add to the doublet?” So, we’re looking at AML therapies from different angles. We’re looking at adding something to the existing new standard of care – those are these new, so-called, triplets.  

We’re looking at still the role of cellular therapy or CAR Ts targeting leukemia cells from an immunotherapy standpoint.  

That remains underdeveloped overall, and we have not succeeded as well, like our lymphoid colleagues in the lymphoma and acute lymphoblastic leukemia realm where there are drugs that are active and FDA-approved.  

So, we’re still trying to identify the right target. But those are some of the areas that are currently under study.
