Gene Variant Detail

IDH1 R132G (gain of function)

Relevant Treatment Approaches IDH Inhibitor (Pan) IDH1 Inhibitor

Filtering

  • 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"

Sorting

  • 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 R132G acute myeloid leukemia sensitive IDH1 Inhibitor BAY1436032 Preclinical - Patient cell culture Actionable In a preclinical study, BAY1436032 decreased (R)-2-hydroxyglutarate (R-2HG) levels and increased differentiation of patient-derived acute myeloid leukemia cells harboring IDH1 R132G in culture (PMID: 28232670). 28232670
IDH1 R132G acute myeloid leukemia sensitive IDH1 Inhibitor Ivosidenib FDA approved - On Companion Diagnostic Actionable In a Phase I trial that supported FDA approval, Tibsovo (ivosidenib) treatment resulted in complete remission (CR) in 21.6% (27/125), CR with partial hematological recovery (CRh) in 8.8% (11/125), and overall response (OR) in 41.6% (52/125) of patients with relapsed or refractory acute myeloid leukemia harboring a susceptible IDH1 mutation (R132C/G/H/L/S) as detected by an FDA-approved test (PMID: 29860938; NCT02074839). detail... 29860938 detail...
IDH1 R132G acute myeloid leukemia sensitive IDH1 Inhibitor Ivosidenib FDA approved - On Companion Diagnostic Actionable In a Phase I trial that supported FDA approval, Tibsovo (ivosidenib) treatment resulted in complete remission (CR) in 28.6% (8/28), CR with partial hematological recovery (CRh) in 14.3% (4/28) of patients age 75 or older with untreated acute myeloid leukemia harboring a susceptible IDH1 mutation (R132C/G/H/L/S) as detected by an FDA-approved test, with a median treatment duration of 4.3 months (PMID: 29860938; NCT02074839). detail... 29860938 detail...
IDH1 R132G chondrosarcoma predicted - sensitive IDH1 Inhibitor Ivosidenib Case Reports/Case Series Actionable In a Phase I trial, Tibsovo (ivosidenib) treatment was tolerated, substantially decreased plasma 2-HG levels, and resulted in a median progression-free survival of 5.6 months and stable disease in 52% (11/21) of patients with chondrosarcoma harboring IDH1 mutations, including IDH1 R132G (n=3) (PMID: 32208957; NCT02073994). 32208957
IDH1 R132G cholangiocarcinoma predicted - sensitive IDH1 Inhibitor Ivosidenib FDA approved - On Companion Diagnostic Actionable In a Phase III (ClarIDHy) trial that supported FDA approval, Tibsovo (ivosidenib) treatment significantly improved median progression-free survival (2.7 vs 1.4 mo, HR=0.37, p<0.001) and prolonged median overall survival (10.8 vs 9.7 mo, HR=0.69, p=0.06) compared to placebo in patients with advanced cholangiocarcinoma harboring IDH1 mutations including R132C/H/L/G/S, resulted in favorable objective response rate (2%, 3/124 vs 0%, 0/61) and stable disease rate (51% vs 28%) (PMID: 32416072; NCT02989857). detail... 32416072 detail...
IDH1 R132G Advanced Solid Tumor predicted - sensitive IDH1 Inhibitor DS-1001b Preclinical - Cell culture Actionable In a preclinical study, transformed human cells expressing IDH1 R132G demonstrated sensitivity to DS-1001b in culture, resulting in reduced production of the oncometabolite 2-hydroxyglutarate (2-HG) (PMID: 31727689). 31727689
IDH1 R132G acute myeloid leukemia sensitive IDH1 Inhibitor 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...
