What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

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.
