💬In plain words
What the trial is, and whether it could suit you
This phase II trial studies the effect of venetoclax together with busulfan, cladribine, and fludarabine in treating patients with high-risk acute myeloid leukemia or myelodysplastic syndrome who are undergoing stem cell transplant. Chemotherapy drugs, such as venetoclax, busulfan, cladribine, and fludarabine, 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. Adding venetoclax to the current standard of care stem cell transplant regimen of busulfan, fludarabine, and cladribine may help to control high-risk acute myeloid leukemia or myelodysplastic syndrome.
