Leukemia transplant study tests lower radiation for better outcomes

NCT ID NCT06803745

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

Summary

This trial tests whether a lower dose of total body irradiation (200 cGy) before a bone marrow transplant works as well as a standard higher dose (400 cGy) for people with acute leukemia. The goal is to see which dose leads to fewer severe side effects like graft-versus-host disease and better survival without relapse. About 160 participants will be randomly assigned to one of the two radiation doses as part of their transplant preparation.

What this could mean

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

Active substance

total body irradiation (TBI) at 200 or 400 cGy

What this could lead to

If it works, this could identify the best radiation dose to reduce severe complications and improve long-term survival after transplant for leukemia patients.

What could go wrong

This is a phase 2 trial with only 160 participants, so results may not apply to everyone. Radiation can cause side effects, and the lower dose might not control the disease as well.
