Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess how the body absorbs, breaks down (metabolism), and removes (excretes) radiolabeled bleximenib (a drug molecule that has been chemically bonded with a radioactive isotope which emits radiation making it easier to track in the body) in participants with acute leukemia (highly aggressive blood cancer typically characterized by large numbers of immature white blood cells in the bone marrow).

Study Groups

Bleximenib

Participants will receive a single oral dose of 14C-bleximenib on Cycle 1 Day 1. The recommended Phase 2 dose (RP2D) of bleximenib will start on Cycle 1 Day 2 with non-radiolabeled bleximenib and will continue until the end of Cycle 1 (cycle duration=28 days), with subsequent roll-over for eligible participants to 75276617ALE1001 (NCT04811560) for continued non-radiolabeled bleximenib administration as appropriate.
