IDH1 R132C IDH1 S280F | acute myeloid leukemia | predicted - resistant | Ivosidenib | Case Reports/Case Series | Actionable | In a clinical study, IDH1 S280F was identified as an acquired mutation in cis with the original IDH1 R132C in a patient with acute myeloid leukemia (AML), who developed resistance to Tibsovo (ivosidenib) after initial response (PMID: 29950729). | 29950729 |
IDH1 R132C IDH1 S280F | acute myeloid leukemia | predicted - resistant | Ivosidenib | Case Reports/Case Series | Actionable | In a clinical case study, a patient with acute myeloid leukemia (AML) harboring IDH1 R132C progressed following an initial response to treatment with Tibsovo (ivosidenib), and was found to have acquired IDH1 S280F (PMID: 33832922). | 33832922 |
IDH1 R132C IDH1 S280F | acute myeloid leukemia | predicted - resistant | Ivosidenib | Case Reports/Case Series | Actionable | In a Phase I trial, IDH1 S280F was identified at progression in 3 patients with acute myeloid leukemia harboring IDH1 R132C who previously responded to Tibsovo (ivosidenib) treatment (PMID: 32380538; NCT02074839). | 32380538 |
IDH1 R132H IDH1 S280F | leukemia | predicted - resistant | Ivosidenib | Preclinical - Biochemical | Actionable | In a preclinical study, Tibsovo (ivosidenib) did not inhibit Idh1 activity and R-2HG production in a leukemia cell line expressing IDH1 R132H and S280F in culture (PMID: 36222845). | 36222845 |
