RATIONALE: 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.

PURPOSE: This randomized phase II trial is studying how well rituximab and/or lenalidomide work in treating patients with follicular non-Hodgkin''''s lymphoma that has relapsed after previous rituximab treatment.

Official Title: Phase II Randomized Study of Rituximab and/or Lenalidomide in Patients With Follicular Non-Hodgkin''''s Lymphoma That Has Relapsed After Prior Rituximab-Based Combination Therapy

Further study details as provided by National Cancer Institute (NCI):




  • Compare TTP after prior rituximab-based combination therapy vs TTP in patients treated with these regimens.
  • Determine the toxicity profile of these regimens in these patients.
  • Correlate Fc-receptor-polymorphism profiling with response in patients treated with these regimens.
  • Correlate changes in natural killer (NK) cells, activated NK cells, activated T-cells, and several plasma cytokines after exposure to lenalidomide therapy, followed by rituximab, with objective response rate in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to time to disease progression after prior rituximab-based combination therapy (≥ 6 months and < 12 months vs ≥ 12 months and < 24 months vs ≥ 24 months). Patients are randomized to 1 of 3 treatment arms.

  • Arm I: Patients receive rituximab IV on days 1, 8, 15, and 22.
  • Arm II: Patients receive oral lenalidomide once daily on days 1-21. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.
  • Arm III: Patients receive lenalidomide as in arm II. Patients also receive rituximab IV on days 8, 15, and 22 of course 1 and day 1 of course 2 of lenalidomide.

After completion of study treatment, patients are followed for up to 10 years from study entry.

PROJECTED ACCRUAL: A total of 180 patients (90 for arm I, 45 each for arms II and III) will be accrued for this study.
