Phase II Investigator Sponsored Study of CPX-351 in Combination With Ivosidenib for Patients With IDH1 Mutated Acute Myeloid Leukemia or High-Risk MDS
M.D. Anderson Cancer Center
Summary
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.
Description
PRIMARY OBJECTIVE: I. To determine the overall response rate (ORR) including CR, CRh, CRi, MLFS, and PR of the combination of CPX-351 and ivosidenib in IDH1-mutated patients with AML or high-risk MDS SECONDARY OBJECTIVES: I. To assess safety of CPX-351 in combination with ivosidenib. II. To determine time to event endpoints including duration of response (DOR), event free survival (EFS) and overall survival (OS). EXPLORATORY OBJECTIVES: I. Evaluate minimal residual disease (MRD) using multiparameter flow cytometry, cytogenetics and molecular evaluation. II. To evaluate molecular and cell…
