Can a simple timing change make leukemia therapy safer?
NCT ID NCT05519579
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a chemotherapy drug (methotrexate) into the spinal fluid before and during blinatumomab treatment can prevent nerve-related side effects in adults with acute lymphoblastic leukemia. The trial enrolls 20 people receiving their first cycle of blinatumomab. Researchers will track how many participants experience neurotoxicity and whether the leukemia responds to treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- methotrexate and blinatumomab
- What this could lead to
- If it works, this could make a key leukemia treatment safer by reducing nerve-related side effects.
- What could go wrong
- This is a small, early-phase trial with only 20 participants, so results may not apply broadly. The approach may not reduce neurotoxicity as hoped.
