First seen Mar 16, 2026 · Last updated Jun 23, 2026 · Updated 17 times
Summary
This phase 1 trial tests giving a powerful chemotherapy combination (CLAG-M or FLAG-Ida) immediately followed by a reduced-intensity stem cell transplant for adults with myeloid cancers that have come back or not responded to treatment. The goal is to find the best dose of total body irradiation to safely kill cancer cells and make room for donor stem cells. Up to 120 participants will be enrolled, and researchers will monitor for graft failure, disease progression, and 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
Chemotherapy (cladribine, cytarabine, filgrastim, mitoxantrone or idarubicin, fludarabine) plus total body irradiation, followed by donor stem cell transplant
What this could lead to
If successful, this approach could offer a more effective treatment option for patients with myeloid cancers that have relapsed or not responded to standard therapy.
What could go wrong
This is an early phase 1 trial, so the main goal is finding a safe dose, not proving it works. There are serious risks like graft failure, severe graft-versus-host disease, and infections.
