Summary

This phase 2 trial tests giving two chemotherapy drugs, clofarabine and melphalan, before a donor stem cell transplant in 72 patients with leukemia or myelodysplastic syndrome in remission. The goal is to prevent the cancer from coming back after the transplant while causing fewer side effects than standard treatments. Participants also receive drugs to prevent rejection and are followed for at least 2 years.

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 melphalan chemotherapy

What this could lead to

If successful, this approach could reduce the chance of leukemia returning after a stem cell transplant, with fewer side effects than standard treatments.

What could go wrong

This is a phase 2 trial with only 72 participants, so results may not apply to everyone. The chemotherapy itself can cause serious side effects, and the transplant carries risks like graft-versus-host disease.
