New hope for tough CML: milder chemo before transplant shows promise

NCT ID NCT07259161

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tests a reduced-toxicity chemotherapy regimen (thiotepa, melphalan, fludarabine) before a stem cell transplant in 40 people with blast-phase chronic myeloid leukemia (CML), an advanced and hard-to-treat stage. The goal is to see if this gentler approach can improve overall survival and reduce treatment-related deaths. Researchers will also track relapse rates 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

thiotepa, melphalan, and fludarabine (chemotherapy drugs)

What this could lead to

If successful, this could offer a safer way to prepare patients with advanced CML for a stem cell transplant, potentially improving survival and reducing severe side effects.

What could go wrong

This is a small, early-phase trial with only 40 participants, so results may not apply to everyone. The treatment still carries risks like infection, organ damage, or graft-versus-host disease.
