An Open-label Phase 3b Study of Ivosidenib in Combination With Azacitidine in Adult Patients Newly Diagnosed With IDH1m Acute Myeloid Leukemia (AML) Ineligible for Intensive Induction Chemotherapy.

Phase 3
Recruiting
Conditions
Acute Myeloid Leukemia (AML)
Interventions
Registration Number
NCT05907057
Lead Sponsor
Servier Affaires Médicales
Brief Summary

The purpose of this study is to learn more about the safety and efficacy of ivosidenib taken with azacitidine to treat adult patients with acute myeloid leukemia (AML) who are presenting a gene mutation called IDH1 (isocitrate dehydrogenase1 mutation-positive \[IDH1m\]) and cannot receive treatment with intensive chemotherapy (IC).

Detailed Description

Participants who are eligible and enroll in the study will attend a study visit on the first day of each 28-day cycle. Study visits will consist of a physical exam, blood work, electrocardiogram (ECG) and other assessments. After treatment discontinuation participants will be contacted every 12 weeks through the end of the study (currently planned for 2026) to assess survival. The study drug, Ivosidenib, will be taken once daily throughout the duration of participation in the study, and Azacitidine will only be administered for 7 days at the beginning of each 28 day cycle. If at any point ivosidenib is made available as a medical prescription at the patient's site, the patient will switch to commercial product and will continue to be followed according to the protocol.
