Phase 1b/2 Study of Oral Decitabine/Cedazuridine (ASTX727) and Venetoclax in Combination With the Targeted Mutant IDH1 Inhibitor Ivosidenib or the Targeted Mutant IDH2 Inhibitor Enasidenib
M.D. Anderson Cancer Center
Summary
This phase Ib/II trials studies the side effects of decitabine/cedazuridine (ASTX727) and venetoclax in combination with ivosidenib or enasidenib, and how well they work in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory). ASTX727 is the combination of a fixed dose of 2 drugs, cedazuridine and decitabine. Cedazuridine may slow down how fast decitabine is broken down by the body, and decitabine may block abnormal cells or cancer cells from growing. Venetoclax may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Enasidenib and ivosidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving decitabine/cedazuridine and venetoclax in combination with ivosidenib or enasidenib may help control acute myeloid leukemia.
Description
PRIMARY OBJECTIVE: I. To determine the safety and tolerability and recommended phase 2 dose (RP2D) of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib (Arm B) for patients with acute myeloid leukemia. (Phase Ib) II. To determine the overall response rate (complete response \[CR\], complete remission with incomplete hematologic recovery \[CRh\], morphologic leukemia-free state \[MLFS\] and partial response \[PR)\] of oral decitabine/cedazuridine (ASTX727) and venetoclax in combination with either ivosidenib (Arm A) or enasidenib…
