Study Details

This phase I trial tests the safety, side effects, best dose and effectiveness of lenalidomide when added to nivolumab and the usual drugs (rituximab and methotrexate) in patients with primary central nervous system (CNS) lymphoma. Lenalidomide may stop or slow primary CNS lymphoma by blocking the growth of new blood vessels necessary for tumor growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Methotrexate is frequently combined with other chemotherapy agents to improve response. This study may help increase the understanding of lenalidomide and nivolumab use in primary CNS lymphoma treatment. In addition, it may help researchers see whether the control of CNS lymphoma can be extended by using these study drugs as maintenance (prolonged therapy) after control is achieved with the initial chemotherapy regimen (induction).

Arms

• Experimental: Treatment (rituximab, methotrexate, lenalidomide, nivolumab)
  INDUCTION: Patients receive rituximab IV on day 1, methotrexate IV over 2 hours or PO on day 2, lenalidomide PO daily on days 5-9, and nivolumab IV over 30 minutes on day 14. (In dose level IV that includes nivolumab, the doses of rituximab for cycles 2-6 may be given on the same day as nivolumab for the previous cycle). Treatment repeats every 14 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who achieve complete response, partial response, or stable disease proceed to maintenance therapy. MAINTENANCE: Within 6 weeks after the last dose of lenalidomide in induction therapy, patients receive lenalidomide PO daily on days 1-21, and nivolumab IV over 30 minutes on day 1. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI, CT, PET/CT, lumbar puncture, bone marrow aspirate and biopsy, testicular ultrasound and ECHO. (See Detailed Description)
