Study Evaluating the Efficacy and Safety of the Addition of Ivosidenib to Oral Azacitidine (Onureg®) in Patients Over 55 With Acute Myeloid Leukemia (AML) and IDH1 Mutation, in Complete Remission After Intensive Chemotherapy.

After remission post-induction and consolidation, maintenance therapy by an ivosidenib and oral azacitidine combination is susceptible to improve the prevention of AML relapse, which remains a major issue in the study population. We assume that the combination of ivosidenib with oral azacitidine will not be less well tolerated than in combination with the subcutaneous form, therapeutic regimen authorized until progression or toxicity. Ivosidenib and Onureg®, being already authorized treatments, it has been decided to use the classic administration schedules and dosages in combination. The primary objective of the study is to evaluate relapse free survival (RFS) at 24 months in patients receiving oral azacitidine with ivosidenib.
