Clinical summary

Summary

This trial is recruiting people with myelodysplastic syndromes (MDS) with an Isocitrate dehydrogenase protein, 1 (IDH1) mutation who have not received prior treatment with a hypomethylating agent.

Eligible participants will be randomised to receive either ivosidenib alone or azacitidine alone.

Ivosidenib will be given as two oral tablets daily throughout the 28-day treatment cycle, and azacitidine will be given by subcutaneous or intravenous (IV) injection for the first 7 days of each 28-day cycle.

Study visits will be conducted every week during Cycle 1 (Days 1, 8, 15 and 22), and Day 1 of each cycle after that. After the last dose of treatment, participants will attend a safety follow-up visit and participants will be followed to assess overall survival. Study visits may include a bone marrow aspirate, physical exam, echocardiogram (ECHO), electrocardiogram (ECG), blood and urine analysis, and questionnaires. 

Conditions

This trial is treating people with myelodysplastic syndromes (MDS) with IDH1 mutation
