Promising combo for IDH1 leukemia hits early snag – trial stopped
NCT ID NCT04250051
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tested whether adding the targeted drug ivosidenib to standard FLAG chemotherapy could help people with a specific genetic form of acute myeloid leukemia (IDH1-mutant AML). The study aimed to find the best dose and check for side effects in patients whose cancer was newly diagnosed, had returned, or was not responding to treatment. However, the trial was terminated early after enrolling only 2 participants, so we have very limited information about its safety or effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
ivosidenib
What this could lead to
If it works, this could point toward a more effective treatment for people with IDH1-mutant AML that has returned or not responded to therapy.
What could go wrong
This was a very early, small Phase 1 trial that was terminated after enrolling only 2 participants. The combination may cause serious side effects, and it is unknown if it works better than standard care.
