Phase 1B/2A Study of Weekly Decitabine and Venetoclax Treatment as Maintenance Therapy in High-Risk Myeloid Malignancy Patients Post Allograft Stem Cell Transplant
Benjamin Tomlinson
Summary
The goal of this interventional clinical trial is to determine if low doses of gentle chemotherapy after bone marrow transplant may prevent relapse and promote an increase in survival and decrease in side effects in participants with acute myeloid leukemia and myelodysplastic syndromes. The main question it aims to answer is whether or not providing a new, gentler way of administering chemotherapy will help control leftover cancer with minimal side effects. This treatment involves decitabine and venetoclax. Participants will receive standard post-transplant care. Participants will be administered decitabine once per week with normal transplant follow up visits, and then will take a venetoclax pill about 6 to 8 hours later. Participants will meet their study team at the beginning, midway, and at the end of the trial to receive bone marrow testing. Participants will receive treatment until either one year of therapy, relapse, or recurrent dose limiting toxicity (DLT) despite dose reduction.
Description
Acute myeloid leukemia (AML) is the most common acute leukemia in adults. While 60-80% patients can achieve remission, a high rate of relapse mandates consolidative treatment. Unfortunately, 40% of AML patients and 30% of myelodysplastic syndrome patients will relapse after alloSCT, and those who relapse after transplant exhibit poor outcomes. As such, prevention of post-transplant relapse remains a key interest. Maintenance therapy with low-intensity chemotherapy and/or targeted therapy is one strategy that holds promise to reduce post-transplant relapse, controlling residual subclinical dise…
