New drug combo aims to boost stem cell transplant success in older blood cancer patients
NCT ID NCT07396480
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 trial tests whether adding the targeted drug venetoclax to standard chemotherapy (fludarabine and melphalan) before a donor stem cell transplant can improve outcomes for patients over 50 with acute myeloid leukemia or myelodysplastic syndrome. The study will compare the new three-drug regimen against the standard two-drug regimen in 186 participants. The goal is to reduce relapse and improve survival without increasing severe graft-versus-host disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Venetoclax (a targeted pill) added to fludarabine and melphalan chemotherapy
- What this could lead to
- If successful, this could become a new standard conditioning regimen before stem cell transplant for older AML/MDS patients, improving long-term survival and reducing relapse.
- What could go wrong
- This is an early-phase 3 trial with 186 participants, so results are not yet proven. Adding venetoclax may increase side effects like infections or organ toxicity, and the benefit over standard chemo is uncertain.

Inclusion Criteria: 1. Aged \> 50 years; 2. Confirmed as acute myeloid leukemia (AML) in remission prior to transplantation, myelodysplastic syndrome (MDS; IPSS: Intermediate-2, high; or IPSS-R: Intermediate, high, very high; or IPSS-M: moderate-high, high, and very high), or myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN) by morphology, immunology, cytogenetics and molecular biology (MICM) typing; 3. Having an eligible donor and scheduled to undergo allogeneic hematopoietic stem cell transplantation (Allo-HCT) from a related or unrelated donor; 4. Karnofsky Performance Score ≥ 70; 5. Eastern Cooperative Oncology Group (ECOG) Performance Status \< 3; 6. Expected survival time \> 12 weeks; 7. Voluntarily signing the informed consent form and being able to understand and comply with all study requirements. Exclusion Criteria: 1. Complicated with severe cardiac insufficiency with a left ventricular ejection fraction (EF) \< 60%; or complicated with severe arrhythmia, and assessed by the investigator as unable to tolerate the intensive conditioning regimen; 2. Complicated with severe pulmonary insufficiency (obstructive and/or restrictive ventilatory disorder), and assessed by the investigator as unable to tolerate the intensive conditioning regimen; 3. Complicated with severe liver function impairment, with liver function indicators (alanine aminotransferase \[ALT\], total bilirubin \[TBIL\]) exceeding 3 times the upper limit of normal (ULN); and assessed by the investigator as unable to tolerate the intensive conditioning regimen; 4. Complicated with severe renal insufficiency, with serum creatinine (Cr) exceeding 2 times the upper limit of normal (ULN); or with a 24-hour creatinine clearance rate (Ccr) \< 50 ml/min, and assessed by the investigator as unable to tolerate the intensive conditioning regimen; 5. Suffering from severe active infection prior to transplantation, and assessed by the investigator as unable to tolerate the intensive conditioning regimen; 6. Having a history of allergic reactions or severe adverse reactions to the drugs involved in the conditioning regimen, and assessed by the investigator as ineligible for enrollment; 7. Other reasons for ineligibility assessed by the investigator.
