Study Summary

This phase I/II trial tests the safety of tafasitamab, retifanlimab, and rituximab (TRR) as a prephase treatment and in combination with standard chemotherapy consisting off cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with untreated diffuse large B-cell lymphoma. Tafasitamab, retifanlimab, and rituximab are monoclonal antibodies. Tafasitamab binds to a protein called CD19, which is found on B-cells (a type of white blood cell) and some types of cancer cells. Rituximab binds to a protein called CD20, which is also found on B-cells and some cancer cells. These monoclonal antibodies may help the immune system kill cancer cells. Immunotherapy with other monoclonal antibodies, such as retifanlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as CHOP, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving TRR in combination with CHOP may kill more cancer cells.
