Phase I/II Study of Lenalidomide (Revlimid), Rituximab, Cyclophosphamide, Doxorubicin, Vincristine and Prednisone (R2CHOP) Chemoimmunotherapy in Patients With Newly Diagnosed Diffuse Large Cell and Follicular Grade IIIA/B B Cell Lymphoma

Why is this study being done?

OBJECTIVES: Primary - To determine the maximum tolerated dose of lenalidomide when given in combination with rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone in patients with newly diagnosed stage II-IV diffuse large cell or grade 3 follicular B-cell lymphoma. (Phase I) - To assess the efficacy of this regimen, in terms of event-free survival and response rate, in these patients. (Phase II) - To assess the safety of this regimen in these patients. (Phase II) Secondary - To assess the host immune function at baseline and after treatment and correlate these parameters with tumor response and event-free survival. OUTLINE: This is a multicenter, phase I dose-escalation study of lenalidomide followed by a phase II study. - Phase I: Patients receive rituximab IV, cyclophosphamide IV, doxorubicin hydrochloride IV, and vincristine IV on day 1, oral prednisone on days 1-5, and oral lenalidomide on days 1-10. Patients also receive pegfilgrastim subcutaneously on day 2. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. - Phase II: Patients receive lenalidomide at the maximum tolerated dose determined in phase I and rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, prednisone, and pegfilgrastim as in phase I. Blood is collected at baseline, before course 3, and after completion of study treatment for translational research studies. Research studies include immune function and cytokine analysis, T- and B- quantitative lymphocyte analysis, and single nucleotide polymorphism analysis. After completion of study therapy, patients are followed every 3 months for 1 year, every 4 months for 1 year, and then every 6 months for 3 years.
