Can a new drug combo make stem cell transplants safer for frail AML patients?
NCT ID NCT07762508
First seen Aug 13, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This trial is testing whether a new conditioning regimen, called VABu, can improve outcomes for adults with acute myeloid leukemia (AML) who are in first remission but are too frail for standard transplant prep. The regimen combines venetoclax, azacitidine (or decitabine), and busulfan, given before an allogeneic stem cell transplant. The study will follow 42 participants to see how many survive for two years after the transplant, and also track relapse, transplant-related complications, and infections. The goal is to find a safer, more effective way to prepare frail patients for a potentially curative transplant.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A combination of venetoclax, azacitidine (or decitabine), and busulfan, given before a stem cell transplant.
- What this could lead to
- If successful, this could offer a safer and more effective transplant preparation for AML patients who are too frail for standard regimens, potentially improving their chances of long-term survival.
- What could go wrong
- This is a small, single-arm study, so results may not be conclusive. The regimen may still cause serious side effects, including infections or transplant-related complications, and may not improve outcomes for all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age 18 to 70 years. 2. Diagnosis of acute myeloid leukemia (AML) other than acute promyelocytic leukemia (APL), with first complete remission (CR1) achieved after induction chemotherapy. 3. Classified as non-high-risk per ELN 2022 risk stratification guidelines. 4. ECOG performance status ≥ 2 (not due to leukemia) OR Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) ≥ 2. 5. Willing to undergo allogeneic hematopoietic stem cell transplantation and has a suitable donor. 6. Voluntarily signs informed consent form after full understanding of the study. Exclusion Criteria: 1. Allergy to any component of the study drugs. 2. Psychiatric or psychological disorders that prevent cooperation with treatment. 3. Uncontrolled systemic or local severe infection. 4. Severe dysfunction of major organs (heart, lung, liver, kidney) that, in the investigator's opinion, makes the patient unsuitable for enrollment. 5. Currently participating in or planning to participate in any other clinical study. 6. Any other conditions that, in the investigator's opinion, make the patient unsuitable for enrollment.
