---|---|---|---|---|---|---|---|---|
IDH1 R132X | acute myeloid leukemia | no benefit | IDH1 Inhibitor | BAY1436032 | Phase I | Actionable | In a Phase I trial, treatment with BAY1436032 in acute myeloid leukemia patients harboring an IDH1 R132X mutation demonstrated safety and resulted in an overall response rate of 15% (4/27), including one complete remission, one partial remission, and morphologic leukemia-free state in two patients, stable disease in 67% (18/27), and a median overall survival of 6.6 months, however, due to low response rates for all doses, further clinical development was not supported (PMID: 32733012; NCT03127735). | 32733012 |
IDH1 R132X | acute myeloid leukemia | sensitive | IDH1 Inhibitor | Azacitidine + Ivosidenib | Phase III | Actionable | In a Phase III trial (AGILE), Tibsovo (ivosidenib) and Vidaza (azacytidine) 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 (azacytidine) plus placebo in patients with newly diagnosed acute myeloid leukemia harboring IDH1 mutations including R132C/H/G/L/S (PMID: 35443108; NCT03173248). | 35443108 |
IDH1 R132X | acute myeloid leukemia | predicted - sensitive | CG-806 | Preclinical - Patient cell culture | Actionable | In a preclinical study, patient-derived acute myeloid leukemia cells harboring IDH1 R132X mutations demonstrated increased sensitivity to CG-806 compared to wild-type cells in culture (Proceedings of the American Association for Cancer Research, Vol 60, Mar 2019, Abstract #1323). | detail... | |
IDH1 R132X | acute myeloid leukemia | sensitive | IDH1 Inhibitor | IDH305 | Phase I | Actionable | In a Phase I trial, IDH305 treatment resulted in objective response in 33% (7/21) of acute myeloid leukemia patients harboring IDH1 R132 mutations, including complete remission in 3 (14%) and partial remission in 4 (19%) patients (Blood 2016 128 (22):1073). | detail... |
IDH1 R132X | low grade glioma | predicted - sensitive | IDH1 Inhibitor | Ivosidenib | Phase I | Actionable | In a Phase I trial, low grade glioma patients with an IDH1 mutation (n=66; R132H=57, R132C/G/S=1 each, R132X=5) treated with Tibsovo (ivosidenib) demonstrated an overall response rate of 2.9% (1/35, 1 partial response) and stable disease in 85.7% (30/35) of patients with a non-enhancing glioma versus no responses and stable disease in 45.2% (14/31) of patients with an enhancing glioma, and led to a median progression-free survival of 13.6 months and 1.4 months, respectively (PMID: 32530764; NCT02073994). | 32530764 |
