Can a lower drug dose prevent transplant complications just as well?

NCT ID NCT06705062

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a lower dose of the drug cyclophosphamide can prevent graft-versus-host disease (GVHD) after stem cell transplants from unrelated or half-matched donors. About 316 participants will receive either a reduced dose (35 mg/kg) or the standard dose (50 mg/kg), along with other immune-suppressing drugs. The goal is to see if the lower dose works as well but causes fewer side effects.

What this could mean

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

Active substance

cyclophosphamide (reduced dose 35 mg/kg vs standard 50 mg/kg), tacrolimus, and anti-thymocyte globulin

What this could lead to

If successful, this could offer a safer way to prevent graft-versus-host disease after stem cell transplants, with fewer side effects and similar protection.

What could go wrong

This is a phase 3 trial, but the reduced dose may not prevent GVHD as well as the standard dose. Results may not apply to all transplant types or patient groups.
