Ibrutinib in Combination With Rituximab and Lenalidomide in Treating Patients With Previously Untreated, Stage II-IV Follicular Lymphoma or Marginal Zone Lymphoma

This phase II trial studies how well ibrutinib in combination with rituximab and lenalidomide works in treating patients with previously untreated, stage II-IV follicular lymphoma or marginal zone lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Giving ibrutinib in combination with rituximab and lenalidomide may work better in treating follicular lymphoma or marginal zone lymphoma.
