Oncology Drug Reference Sheet: Ivosidenib

Adding to its earlier approvals for use in adults with acute myeloid leukemia (AML), on August 25, 2021, the U.S. Food and Drug Administration (FDA) approved ivosidenib (Tibsovo^®) for adults with previously treated, locally advanced or metastatic cholangiocarcinoma. Cholangiocarcinoma, or cancer of the bile ducts, is a rare cancer, and ivosidenib is the only currently approved agent for patients with an IDH1 variant.
