New trial aims to stop leukemia relapse after transplant

NCT ID NCT03821610

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This trial compares two different chemotherapy and radiation regimens given before a stem cell transplant for adults aged 40-70 with acute lymphoblastic leukemia (ALL) in remission. The goal is to see if a stronger regimen (using total body irradiation and cyclophosphamide) can reduce the chance of the cancer returning without increasing the risk of dying from the transplant. About 242 patients will be randomly assigned to one of the two regimens and followed for at least 3 years.

What this could mean

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

Active substance

Fludarabine, Melphalan, Alemtuzumab, Cyclophosphamide, Mesna, Total Body Irradiation (8Gy)

What this could lead to

If successful, this could identify a better pre-transplant regimen that reduces the chance of leukemia returning after a stem cell transplant.

What could go wrong

This is a Phase 2 trial, so results are still preliminary. The stronger regimen may increase side effects or transplant-related deaths, and it may not work for all patients.
