Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This phase 3 trial compares an anti-CD25 monoclonal antibody (daclizumab) with methotrexate for preventing acute graft-versus-host disease (GVHD) in people with blood cancers receiving a half-matched stem cell transplant. GVHD is a serious complication where donor immune cells attack the patient's body. The study aims to see if the antibody can reduce GVHD and side effects like mouth sores and slow blood recovery. Participants are randomly assigned to receive either the antibody or methotrexate, along with standard GVHD prevention drugs.

What this could mean

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

Active substance
Anti-CD25 monoclonal antibody (daclizumab)
What this could lead to
If successful, this could offer a safer way to prevent graft-versus-host disease after stem cell transplants, reducing side effects like mouth sores and slow blood recovery.
What could go wrong
This is an early-phase trial with 186 participants, so results may not apply to all patients. The anti-CD25 antibody could still cause infections or other complications.
