Untreated Adult Acute Myeloid Leukemia

This phase II trial studies how well cladribine, idarubicin, cytarabine, and venetoclax work in patients with acute myeloid leukemia, high-risk myelodysplastic syndrome, or blastic phase chronic myeloid leukemia. Drugs used in chemotherapy, such as cladribine, idarubicin, cytarabine, and venetoclax, 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.

This phase II trial studies the side effects and how well fludarabine phosphate, cytarabine, filgrastim-sndz, gemtuzumab ozogamicin, and idarubicin hydrochloride work in treating patients with newly diagnosed acute myeloid leukemia or high-risk myelodysplastic syndrome. Drugs used in chemotherapy, such as fludarabine phosphate, cytarabine, and idarubicin hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to a antitumor drug, called calicheamicin. Gemtuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD33 receptors, and delivers calicheamicin to kill them. Colony-stimulating factors, such as filgrastim-sndz, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving fludarabine phosphate, cytarabine, filgrastim-sndz, gemtuzumab ozogamicin, and idarubicin hydrochloride may kill more cancer cells.
