Summary
This phase II trial tests how well tafasitamab, lenalidomide and venetoclax work in treating patients with mantle cell lymphoma that has come back (after a period of improvement) (relapsed) or that has not responded to previous treatment (refractory). Tafasitamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Lenalidomide is in a class of medications called immunomodulatory agents. It works by helping the immune system kill cancer cells. 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. Giving tafasitamab, lenalidomide and venetoclax together may kill cancer cells more efficiently in patients with relapsed or refractory mantle cell lymphoma.
