Rituximab and/or Lenalidomide in Treating Patients With Follicular Non-Hodgkin’s Lymphoma That is Not Refractory to Rituximab

Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Lenalidomide may also stop the growth of non-Hodgkin’s lymphoma by blocking blood flow to the cancer. Giving rituximab together with lenalidomide may kill more cancer cells. This randomized phase II trial is studying how well rituximab and/or lenalidomide work in treating patients with follicular non-Hodgkin’s lymphoma that is not refractory to rituximab.
