RATIONALE: Lenalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. 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. Giving lenalidomide together with rituximab may be an effective treatment for multiple myeloma.
PURPOSE: This phase II trial is studying the side effects of giving lenalidomide together with rituximab and to see how well it works in treating patients with recurrent or refractory multiple myeloma.

- To determine the safety and efficacy, as determined by response rate (complete response [CR] + near CR + partial response), of lenalidomide administered with rituximab in patients with relapsed and/or refractory CD20+ multiple myeloma.
- To assess the effects of this regimen on patient lymphocyte subsets (T, B, and NK cells) in peripheral blood and bone marrow samples from these patients.
- To perform detailed phenotypic analyses of NK cells in patient blood and bone marrow samples at baseline and post-treatment.
OUTLINE: Patients receive oral lenalidomide once daily on days 1-21. Treatment with lenalidomide repeats every 28 days for at least 4 courses. Patients also receive rituximab IV once weekly in weeks 2-5 and in week 13. Patients with stable disease then receive rituximab once every 8 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.
Peripheral blood samples are collected at baseline, and after courses 2 and 4. Samples are examined by flow cytometry for lymphocyte subset analysis (T-, B-, and NK-cell percentages and absolute numbers) and NK-cell phenotyping (CD16, CD56, NKG2D expression). Samples are also examined by immunologic assays of isolated peripheral blood mononuclear cells. Bone marrow aspirate samples are also collected at baseline and after course 2. Bone marrow mononuclear cells are isolated and evaluated by CD138+ plasma cell selection, ex vivo antibody-dependent cellular cytotoxicity assays, and bone marrow lymphocyte subset analysis.
After completion of study therapy, patients are followed at 30 days.

Experimental: Lenalidomide and Rituximab
This study will employ a Simon optimal two-stage design. Patients will receive lenalidomide 25 mg daily for days 1-21 of each 28 day cycle. Rituximab 375 mg/m2 will be given weekly for 4 weeks beginning 1 week after the start of lenalidomide therapy (weeks 2-5), and then once 8 weeks later (week 13). Patients with stable disease or better after 4 cycles (week 16, in the absence of delays for toxicity) will be able to continue on therapy on the same lenalidomide schedule and with rituximab 375 mg/m2 given once every 8 weeks.
