Lenalidomide starting at a low dose and escalated based on patient tolerability 21 days of every cycle. Rituximab at 375mg/m2 administered following the first 21 days of lenalidomide monotherapy, continued weekly throughout cycle 2, and then every 4 weeks for subsequent cycles. Each patient may receive up to a maximum of 7 cycles of treatment if no progressive disease or significant toxicity.

The study is a two-arm, multi-center trial of Revlimid® and Rituximab, for the frontline treatment of patients with Chronic Lymphocytic Leukemia (CLL) designed and conducted by the CLL Research Consortium (CRC). The purpose of this study is to determine the response rate of the combination of Revlimid® and Rituximab in previously untreated CLL patients in two arms- those aged 65 years and above and those younger than 65. Secondary objectives will evaluate the safety of the combination of Revlimid® and Rituximab, response duration, improvement in hematologic parameters, and the significance of the tumor flare reaction. All patients will have assessment of known prognostic factors for CLL as well as novel prognostic factors will be evaluated for predicting response to treatment. Biologic corollary studies are designed to evaluate the mechanism of Revlimid® in CLL and the combination of Revlimid® and Rituximab.

The CLL Research Consortium (CRC) is conducting a two-arm, multi-center phase II trial of Revlimid® and rituximab for the first-line treatment of patients with CLL.

Revlimid® (lenalidomide) a derivative of thalidomide with immune-modulating properties. Revlimid® is FDA approved for treatment of relapsed multiple myeloma and 5q- myelodysplastic syndrome. Revlimid® has promising clinical activity in relapsed CLL in two early clinical trials. However, the mechanism(s) whereby Revlimid® is active in CLL is unknown. Rituximab (Rituxan®) is a protein that binds to CD20 expressed on normal and leukemia B cells. Rituximab is FDA approved for the treatment of lymphoma and is used commonly for the treatment of CLL. The purposes of this study are to evaluate the safety and activity of the combination of Revlimid® and rituximab in CLL, elucidate the mechanism of Revlimid® in CLL, and to assess whether prognostic factors might predict those patients likely to benefit from this therapy in the future.

As older patients are commonly under-represented in CLL clinical trials and are less tolerable of frontline therapy that utilizes combinations of fludarabine and cyclophosphamide the trial has two arms; one to specifically assess for the tolerability of the regimen in older subjects.

The primary objective of this study is to determine the response rate of the combination of Revlimid® and Rituximab in previously untreated CLL patients in two arms- those aged 65 years and above and those younger than 65. Secondary objectives will evaluate the safety of the combination of Revlimid® and Rituximab, response duration, improvement in hematologic parameters, activity of the combination in high-risk CLL subsets, and the significance of the tumor flare reaction.

All patients will have baseline assessment of known CLL prognostic factors including: immunoglobulin variable heavy chain (IgVH) gene mutational status, interphase cytogenetics, intracellular ZAP-70 expression, and CD38 expression through the CRC tissue core. These known prognostic features in CLL together with novel prognostic factors will be evaluated for the ability to predict response to treatment with Revlimid® and the combination of Revlimid® and Rituximab. Extensive biologic corollary studies are designed to evaluate the mechanism of Revlimid® in CLL, the impact of Revlimid® on the CLL microenvironment, and Revlimid®'s impact on and rituximab mediated cytotoxicity.

All patients will receive the same treatment. Revlimid® will be started at a low dose and slowly escalated based on patient tolerability. Rituximab will be administered following 21 days of Revlimid® monotherapy. Patients will continue treatment for up to 7 cycles unless there is toxicity or progressive disease. There are three planned response assessments for the subjects: a single agent Revlimid® response assessment prior to the addition of rituximab, after 3 cycles of treatment, and following all the therapy.
