This phase Ib/II clinical trial studies the side effects and best dose of venetoclax and how
well it works when given together with vincristine liposomal in treating patients with T-cell
or B-cell acute lymphoblastic leukemia that has come back or does not respond to treatment.
Venetoclax may stop the growth of cancer cells by blocking some of the enzymes needed for
cell growth. Drugs used in chemotherapy, such as vincristine liposomal, 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 venetoclax together with vincristine
liposomal may work better in treating patients with acute lymphoblastic leukemia.
