Study Summary

This phase II trial tests whether acalabrutinib, venetoclax, and durvalumab work in treating patients with Richter transformation from chronic lymphocytic leukemia or small lymphocytic lymphoma. Richter transformation is a rare condition in which chronic lymphocytic leukemia or small lymphocytic lymphoma changes into a fast-growing type of lymphoma. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving acalabrutinib, venetoclax, and durvalumab may help improve survival in patients with Richter transformation.
