Summary

This early-stage trial tests a new treatment called QUAIL-100, made from a live weakened bacteria, in children and young adults with high-risk leukemia or myelodysplastic syndrome who have already had a stem cell transplant. The main goal is to check safety and side effects. Only 12 participants will be enrolled.

What this could mean

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

Active substance
QUAIL-100 (a live, weakened bacteria given as a therapeutic)
What this could lead to
If it works, this could point toward a new way to help prevent relapse in high-risk leukemia patients after a stem cell transplant.
What could go wrong
This is a very early, first-in-human trial with only 12 participants, so safety and effectiveness are unknown. There is a risk of serious side effects, including graft-versus-host disease.
