IDH1 R132C | acute myeloid leukemia | sensitive | Azacitidine + Ivosidenib | Phase Ib/II | Actionable | In a Phase Ib trial, Tibsovo (ivosidenib) and Vidaza (azacitidine) combination treatment demonstrated a favorable safety profile and resulted in an objective response rate (ORR) of 78.3% (18/23, 14 complete remission) and a 12-month overall survival probability of 82% in patients with newly diagnosed acute myeloid leukemia harboring IDH1 R132C (n=14), R132H (n=4), or R132L (n=3) mutations (PMID: 33119479; NCT02677922). | 33119479 |
IDH1 R132C | acute myeloid leukemia | sensitive | Azacitidine + Ivosidenib | FDA approved - On Companion Diagnostic | Actionable | In a Phase III trial (AGILE) that supported FDA approval, Tibsovo (ivosidenib) and Vidaza (azacitidine) combination therapy significantly improved event-free survival (HR 0.33, p=0.002) and median overall survival (24.0 vs 7.9 mo, HR 0.44, p=0.001) compared to Vidaza (azacitidine) plus placebo in patients with newly diagnosed acute myeloid leukemia harboring IDH1 mutations including R132C/H/G/L/S (PMID: 35443108; NCT03173248). | 35443108 detail... detail... |
