Ibrutinib, Rituximab, Etoposide, Prednisone, Vincristine Sulfate, Cyclophosphamide, and Doxorubicin Hydrochloride in Treating Patients With HIV-Positive Stage II-IV Diffuse Large B-Cell Lymphomas

This phase I trial studies the side effect and best dose of ibrutinib in combination with rituximab, etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride in treating patients with human immunodeficiency virus (HIV)-positive stage II-IV diffuse large B-cell lymphomas. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride, 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 ibrutinib and etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride may work better in treating patients with HIV-positive diffuse large B-cell lymphomas.
