RATIONALE: Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. 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 kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving lenalidomide together with rituximab works in treating patients with follicular or small lymphocytic non-Hodgkin lymphoma that has relapsed or not responded to treatment.

Official Title

A Phase II Trial of the Combination of Lenalidomide and Rituximab in Patients With Relapsed/Refractory Follicular NHL (RV 0163)




  • To determine the response rate in patients with relapsed or refractory follicular or small lymphocytic non-Hodgkin lymphoma treated with lenalidomide and rituximab.


  • To determine the time to disease progression, duration of response, and overall survival of these patients.
  • To determine the tolerability of this regimen in these patients.
  • To assess changes in serum cytokines before and after treatment and correlate these changes with response.

OUTLINE: This is a multicenter study.

Patients receive oral lenalidomide once daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also receive rituximab IV on days 15 and 22 of course 1 and on days 1 and 8 of course 2. Patients who do not achieve complete response after 2 courses of rituximab may receive up to 4 additional doses of rituximab once weekly for 4 weeks.

Blood samples are collected at baseline and after treatment for cytokine analysis.

After completion of study treatment, patients are followed at 30 days and then every 3 months thereafter.

For people ages 18 years and up


  • Histologically* confirmed non-Hodgkin lymphoma, including one of the following subtypes:
    • Grade 1, 2, or 3a (> 15 centroblasts per high-power field with centrocytes present) follicular lymphoma according to WHO criteria
    • Small lymphocytic lymphoma
  • NOTE: *Bone marrow biopsies as the sole means of diagnosis are not acceptable, but they may be submitted in conjunction with nodal biopsies or extra-nodal biopsies; fine-needle aspirates are not acceptable for diagnosis.
