A Phase 2 Study of Venetoclax in Relapsed Classic or Variant Hairy Cell Leukemia
National Cancer Institute (NCI)
Summary
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.
Description
PRIMARY OBJECTIVE: I. To determine the objective response rate (ORR) of venetoclax. SECONDARY OBJECTIVES: I. To determine the complete remission (CR) and minimal residual disease (MRD)-negative CR rates of venetoclax in relapsed hairy cell leukemia/hairy cell leukemia variant (HCL/HCLv). II. To determine the rates of MRD-negative by blood flow cytometry with venetoclax. III. To determine the safety of venetoclax in relapsed HCL/HCLv. IV. To determine the response and CR duration and MRD-negative survival in relapsed HCL/HCLv receiving venetoclax. EXPLORATORY OBJECTIVES: I. To correlate…
