Can a gentler chemo prep make stem cell transplants safer for blood cancer patients?

NCT ID NCT01063647

First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time

Summary

This trial is testing whether a chemotherapy drug called treosulfan, given in different doses along with fludarabine, can safely prepare patients with advanced blood cancers for a stem cell transplant. The study focuses on patients who are not eligible for the standard, more intense conditioning regimens due to increased toxicity risk. The goal is to see if this approach is feasible and tolerable, and whether it can help keep the cancer in remission after the transplant.

What this could mean

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

Active substance
Treosulfan (a chemotherapy drug) combined with fludarabine, used as a conditioning regimen before stem cell transplantation
What this could lead to
If successful, this could provide a safer conditioning option for patients with blood cancers who cannot tolerate standard high-dose chemotherapy or radiation, potentially improving transplant outcomes.
What could go wrong
This is an early-phase trial with a small number of patients, so results may not be conclusive. The treatment carries risks of serious side effects, including transplant-related mortality and graft-versus-host disease.
