OX40, Venetoclax, Avelumab, Glasdegib, Gemtuzumab Ozogamicin, and Azacitidine in Relapsed or Refractory Acute Myeloid Leukemia

This phase Ib/II trial studies the side effects and best dose of anti-OX40 antibody PF-04518600 (OX40) and how well it works alone or in combination with venetoclax, avelumab, glasdegib, gemtuzumab ozogamicin, and azacitidine in treating patients with acute myeloid leukemia that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as OX40, avelumab, and gemtuzumab ozogamicin, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Glasdegib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as venetoclax and azacitidine, 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. Giving OX40, venetoclax, avelumab, glasdegib, gemtuzumab ozogamicin, and azacitidine may work better in treating patients with acute myeloid leukemia.
