Acute Myeloid Leukemia With Gene Mutations

This phase II trial investigates how well CPX-351 and ivosidenib work in treating patients with acute myeloid leukemia or high-risk myelodysplastic syndrome that has IDH1 mutation. The safety of this drug combination will also be studied. IDH1 is a type of genetic mutation (change). Chemotherapy drugs, such as CPX-351, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. The purpose of this trial is to learn if CPX-351 in combination with ivosidenib can help to control IDH1-mutated acute myeloid leukemia or high-risk myelodysplastic syndrome.

The goal of this clinical trial is to learn if the combination of oral decitabine plus ivosidenib works to treat naïve adult patients with acute myeloid leukemia (AML) with IDH1 R132 mutation older than 60 years old or those who are older than 18 years old with defined comorbidities that make them not suitable for standard induction therapy. The main objectives of this clinical trial are: * Asses the Complete Remission (CR) and Complete Remission with incomplete marrow recovery (CRi) rates of this treatment. * Determine the incidence and severity of all adverse events (AEs). All participants will receive oral ivosidenib and oral decitabine in treatment cycles of 28 days until disease progression, lack of clinical benefit or the end of the study. Patients who achieve CR/CRi will be elegible to receive allogeneic stem cell transplantation.
