New hope for Hard-to-Treat leukemia: targeted pill combined with chemotherapy enters human trials
NCT ID NCT06226571
First seen Jun 27, 2026 · Last updated Sep 17, 2026 · Updated 4 times
Summary
This early-stage trial is testing a new oral drug called SNDX-5613 alongside standard intensive chemotherapy in people newly diagnosed with acute myeloid leukemia (AML) that has specific genetic changes (KMT2A, NPM1, or NUP98). The study aims to see if the combination is safe and tolerable, and how well it works. About 76 participants will receive the drug during induction, consolidation, and maintenance phases of treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SNDX-5613 (a targeted cancer pill) combined with standard chemotherapy drugs (cytarabine, daunorubicin or idarubicin)
- What this could lead to
- If successful, this could lead to a new treatment option for certain genetic types of AML that are hard to treat.
- What could go wrong
- This is an early Phase 1 trial with only 76 people, so safety and effectiveness are not yet proven. Side effects from the drug combination are unknown.
Why investors are watching
Syndax Pharmaceuticals runs a phase 1 trial of revumenib combined with intensive chemotherapy in people newly diagnosed with AML whose cancer carries KMT2A, NPM1, or NUP98 gene alterations. The trial tests safety, tolerability, and clinical activity in 96 participants. For a small company, a readout here matters because it points to whether revumenib can move into newly diagnosed patients, a larger group than the relapsed or refractory settings the drug was first studied in.
If it works: A positive result could support advancing revumenib into larger trials for newly diagnosed AML, which may broaden the patient population the drug can reach. That could make the program more valuable to partners or acquirers.
If it fails: Combining revumenib with intensive chemotherapy may cause side effects that limit dosing or stop the trial. Phase 1 trials often fail or produce unclear results, and any delay or setback could hurt a small company that depends on a limited pipeline.
