Gene Variant Detail

IDH1 R132X (unknown)

Relevant Treatment Approaches IDH Inhibitor (Pan) IDH1 Inhibitor


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

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
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 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 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...
