Olutasidenib

To learn if olutasidenib can help to control CCUS, MDS, and/or CMML. The safety of the drug will also be studied.

This MyeloMATCH Master Screening and Reassessment Protocol (MSRP) evaluates the use of a screening tool and specific laboratory tests to help improve participants' ability to register to clinical trials throughout the course of their myeloid cancer (acute myeloid leukemia or myelodysplastic syndrome) treatment. This study involves testing patients' bone marrow and blood for certain biomarkers. A biomarker (sometimes called a marker) is any molecule in the body that can be measured. Doctors look at markers to learn what is happening in the body. Knowing about certain markers can give doctors more information about what is driving the cancer and how to treat it. Testing patients' bone marrow and blood will show doctors if patients have markers that specific drugs can target. The marker testing in this study will let doctors know if they can match patients with a treatment study (myeloMATCH clinical trial) that tests treatment for the type of cancer they have or continue standard of care treatment with their doctor on the Tier Advancement Pathway (TAP).

This phase II trial studies how well giving olutasidenib with azacitidine, followed by olutasidenib maintenance, works in treating patients with IDH1-mutated acute myeloid leukemia (AML) who have received prior treatment with venetoclax plus a hypomethylating agent (HMA-Ven). Olutasidenib and azacitidine may inhibit the growth of cancer cells by blocking certain enzymes required for cell growth. Maintenance therapy can help prevent or delay cancer from coming back. Olutasidenib with azacitidine followed by olutasidenib maintenance may be effective in treating patients with IDH1-mutated AML who have received prior HMA-Ven.
