What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether individuals with acute myeloid leukemia (AML) who clear certain genetic mutations with chemotherapy have better outcomes compared to historical data. Participants will receive cytarabine, a chemotherapy drug, with the treatment plan tailored to specific mutations. Suitable candidates for this trial include those with a type of AML not related to previous cancer treatments, who are in remission after initial treatment but have not fully recovered their blood counts. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, providing participants an opportunity to contribute to significant advancements in AML treatment.

Do I have to stop taking my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with your doctor or the trial coordinators.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that cytarabine commonly treats certain types of leukemia, such as acute myeloid leukemia (AML). Studies have found it is usually well-tolerated, but it can cause side effects. Common side effects include nausea, vomiting, and low blood cell counts, which can lead to infections or bleeding. Some patients might also experience liver issues or a skin rash.

High-dose cytarabine, known as HiDAC, is often used in treatment plans and has proven effective. Patients should know that side effects can intensify at higher doses, potentially causing eye irritation or nervous system issues, such as confusion or balance problems.

Cytarabine is part of standard leukemia treatments and has received FDA approval for this use, indicating a good understanding of its safety. However, anyone considering joining a trial should discuss potential risks and benefits with their healthcare provider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about the treatments in this trial because they focus on personalized strategies for tackling acute myeloid leukemia (AML). Unlike traditional approaches, which might use a one-size-fits-all method, this trial uses genomic assessment to determine the best course of action. For patients with persistent mutations, the investigator can choose between high-dose cytarabine (HiDAC) or an allogeneic stem cell transplant (AlloSCT), offering a tailored approach based on genetic markers. Meanwhile, patients showing mutation clearance receive HiDAC as a consolidation therapy, with the potential addition of an FLT3 inhibitor for certain mutations. This personalized strategy aims to improve outcomes by targeting specific cancer characteristics, making it a promising frontier in AML treatment.

What evidence suggests that this trial's treatments could be effective for acute myeloid leukemia?

Studies have shown that high-dose cytarabine (HiDAC), which participants in this trial may receive, effectively treats acute myeloid leukemia (AML). Some treatment plans using cytarabine have achieved cure rates of 75–80% in certain cases. In this trial, patients with ongoing leukemia-related genetic changes may receive a stem cell transplant from a donor (alloSCT) as another treatment option. Research indicates that this type of transplant can improve survival rates, with some studies showing about 40% of patients living at least five years after the procedure. Both treatments in this trial aim to improve outcomes for people with AML, but their effectiveness can vary based on individual patient factors. ^{6 7 8 9 10}

Participants must be in remission post-induction therapy and agree to use contraception. Excluded are those with AML due to prior chemo/radiation, other hematological malignancies, significant medical issues affecting compliance, known HIV/HBV/HCV infections, or pregnancy.

Inclusion Criteria

I am considered a good candidate for intensive chemotherapy.

What Are the Treatments Tested in This Trial?

Interventions

• Allogeneic stem cell transplant
• Bone marrow aspiration
• Cytarabine
• Punch skin biopsy

Trial Overview

The study tests if clearing leukemia-associated mutations using standard chemotherapy improves survival compared to historical data. It also assesses outcomes for patients whose mutations persist and may receive either chemotherapy or a stem cell transplant based on the physician's discretion.

How Is the Trial Designed?

Group I: Cohort B: Investigator's choice (HiDAC, AlloSCT) Experimental Treatment 5 Interventions

* At the time of diagnostic bone marrow biopsy, samples will be clinically sequenced via ClinSeq * Patients who have persistent leukemia-associated mutations, defined as a LAM VAF ≥2.5% will be assigned to the investigator's choice arm. * Patients assigned to this arm may received either HiDAC or AlloSCT. * HiDAC = Standard regimen of cytarabine 1.5 g/m\^2 or 3 g/m\^2 over 2-3 hours twice a day on Days 1, 3, \& 5 of each 28 day cycle for 3-4 cycles. Can be replaced by Onureg with permission from PI. * The source of stem cell product, donor selection, conditioning regimen, graft-versus-host-prophylaxis, and supportive care will be at the discretion of the treatment physician * For patients with the FLT3-ITD or a FLT3-TKD mutation, therapy with the FDA-approved FLT3 inhibitor midostaurin is permitted at the discretion of the treating physician.

Group II: Cohort A: HiDAC Experimental Treatment 4 Interventions

* At the time of diagnostic bone marrow biopsy, samples will be clinically sequenced via ClinSeq * Patients who have clearance of their leukemia-associated mutations, defined as a LAM VAF \<2.5% will be assigned to the high-dose cytarabine consolidation (HiDAC) arm. * HiDAC = Standard regimen of cytarabine 1.5 g/m\^2 or 3 g/m\^2 over 2-3 hours twice a day on Days 1, 3, \& 5 of each 28 day cycle for 3-4 cycles. Can be replaced by Onureg with permission from PI. * For patients with the FLT3-ITD or a FLT3-TKD mutation, therapy with the FDA-approved FLT3 inhibitor midostaurin is permitted at the discretion of the treating physician.

Published Research Related to This Trial

The MiSeq next-generation sequencing platform effectively screened 54 cancer-related genes in 63 samples from patients with acute myeloid leukemia, showing complete concordance with results from other established testing methods.

MiSeq demonstrated high accuracy in detecting mutations at low frequencies (as low as 1.5%) and offers advantages such as a quick 4-day turnaround time and the ability to assess both routine and emerging genetic markers, making it a promising tool for clinical applications in monitoring and treating acute myeloid leukemia.
