First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether replacing fludarabine with clofarabine in the chemotherapy given before a stem cell transplant can help more adults with acute myeloid leukemia (AML) stay alive longer. About 302 patients whose AML is in remission will be randomly assigned to one of two reduced-intensity chemo regimens. The goal is to see if the clofarabine-based regimen improves two-year survival compared to the standard fludarabine-based regimen.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Clofarabine and Busulfan (compared to Fludarabine and Busulfan)

What this could lead to

If clofarabine works better, this could lead to a new standard pre-transplant regimen that lowers relapse risk and improves survival for AML patients.

What could go wrong

This is a mid-stage trial with 302 participants, so results are not yet proven. Clofarabine may cause more side effects, and the survival benefit may not hold up in larger studies.
