IDH1 mutations can play a critical role in the development of AML1-4

IDH1 mutations are driver mutations and occur in 6% to 10% of patients with AML2-4

IDH1 mutations have been associated with a negative prognosis in AML5,6

2-HG, 2-hydroxyglutarate.

Test for IDH1 mutations at diagnosis so you can offer targeted therapy to appropriate patients7

  • Patients without IDH1 mutations at diagnosis should be retested at relapse because a mutation in IDH1 may emerge during treatment and at relapse7
  • In the pivotal trial, IDH1 mutations were identified by a local or central diagnostic test and confirmed retrospectively using the Abbott RealTime™ IDH1 assay, which is the FDA-approved test for selection of patients with AML for treatment with TIBSOVO7

TIBSOVO targets the mutant IDH1 enzyme to restore myeloid differentiation1,7

Differentiation Restored with TIBSOVO®, Chart
  • In blood samples from patients with AML with mutated IDH1, ivosidenib decreased 2-HG levels ex-vivo, reduced blast counts, and increased percentages of mature myeloid cells7
  • Ivosidenib was shown to inhibit selected IDH1 R132 mutants at much lower concentrations than wild-type IDH1 in vitro7
  • Susceptible IDH1 mutations are defined as those leading to increased levels of 2-HG in the leukemia cells and where efficacy is predicted by 1) clinically meaningful remissions with the recommended dose of ivosidenib and/or 2) inhibition of mutant IDH1 enzymatic activity at concentrations of ivosidenib sustainable at the recommended dosage according to validated methods7
    • Susceptible IDH1 mutations are R132C, R132G, R132H, R132L, and R132S7

TIBSOVO is indicated for the treatment of acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test in:

  • Adult patients with newly diagnosed AML who are ≥75 years old or who have comorbidities that preclude use of intensive induction chemotherapy.
Indications & Important Safety Information



Patients treated with TIBSOVO have experienced symptoms of differentiation syndrome, which can be fatal if not treated. Symptoms may include fever, dyspnea, hypoxia, pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain or peripheral edema, hypotension, and hepatic, renal, or multi-organ dysfunction. If differentiation syndrome is suspected, initiate corticosteroid therapy and hemodynamic monitoring until symptom resolution.
