Ibrutinib, Rituximab, Venetoclax, and Combination Chemotherapy in Treating Patients With Newly Diagnosed Mantle Cell Lymphoma

This phase II trial studies how well ibrutinib and rituximab given together with venetoclax and combination chemotherapy work in treating patients with newly diagnosed mantle cell lymphoma. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Drugs used in chemotherapy such as, cyclophosphamide, vincristine, doxorubicin, and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ibrutinib, rituximab, and venetoclax together with combination chemotherapy may work better in treating patients with mantle cell lymphoma.
