Summary
This phase I/II trial studies the side effects and best dose of lenalidomide when given together with nivolumab and to see how well they work in treating patients with non-Hodgkin or Hodgkin lymphoma that has come back (recurrent) and does not respond to treatment (refractory). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Lenalidomide may stop or slow non-Hodgkin or Hodgkin lymphoma by blocking the growth of new blood vessels necessary for tumor growth. Giving nivolumab and lenalidomide may work better than nivolumab alone in treating patients with non-Hodgkin or Hodgkin lymphoma.
