Venetoclax and ASTX727 for the Treatment of Relapsed, Refractory, or Newly Diagnosed Acute Myeloid Leukemia

• Status: Recruiting
• Trial end date: 2022-10-15
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies the possible benefits of venetoclax and ASTX727 in treating patients with acute myeloid leukemia that has come back (relapsed) or does not respond to treatment (refractory), or elderly patients with newly diagnosed acute myeloid leukemia who are not candidates for intensive chemotherapy. Venetoclax may help block the formation of growths that may become cancer. 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. Giving venetoclax and ASTX727 may help to control the disease.

• Phase: Phase 2
