New pill shows promise for Hard-to-Treat leukemia
NCT ID NCT04811560
First seen Jun 25, 2026 · Last updated Aug 28, 2026 · Updated 5 times
Summary
This study tests a new oral drug called bleximenib for people with acute leukemia that has come back or not responded to treatment. The drug targets specific genetic changes in the cancer cells. The trial has two phases: first to find the safest dose, then to see how well it works in up to 420 participants.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bleximenib (a menin-KMT2A inhibitor pill)
- What this could lead to
- If successful, this could lead to a new targeted treatment option for people with acute leukemia who have certain genetic mutations and have not responded to other therapies.
- What could go wrong
- This is an early phase 1/2 trial, so safety and the right dose are still being figured out. It may not work for everyone, and side effects are possible.
This is an AI summary of the original study and may miss details. Read our disclaimer.
