Decitabine and Venetoclax Treatment as Maintenance Therapy in Patients Post Allograft Stem Cell Transplant

NCT06129734 · Status: RECRUITING · Phase: PHASE1/PHASE2 · Type: INTERVENTIONAL · Enrollment: 20

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.

Conditions

Interventions

DRUG

Venetoclax

Venetoclax is a BCL2 inhibitor. It is administered at low doses and used in combination with other hypomethylating agents such as decitabine to manage participants with acute myeloid lymphoma who have undergone stem cell transplant. Participants will initiate therapy with decitabine that will be followed by venetoclax 400 mg oral 6-8 hours later. Participants will continue this dose each week. The venetoclax dose will be reduced to 100 mg once per week if the participant is being treated with posaconazole or voriconazole (strong CYP3A4 inhibitors) (considered dose equivalent to venetoclax 400 mg 1X/week). The venetoclax dose will be reduced 200 mg once per week if the participant is being treated with fluconazole or isavuconazole (moderate CYP3A4 inhibitors) (considered dose equivalent to venetoclax 400 mg 1X/week). This clinical trial is administering venetoclax well below the current FDA approved dosing.

DRUG

Decitabine

Decitabine is a hypomethylating agent. It is administered at low doses and used in combination with venetoclax to manage participants with acute myeloid lymphoma who have undergone stem cell transplant. Participants initiate therapy with 5 mg/m2 decitabine subcutaneous every week followed by venetoclax.
