What this Trial Is About

This phase II trial tests how well venetoclax works in treating patients with hairy cell leukemia that has come back after a period of improvement (relapsed). Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival.
