 The first secondary objective is to evaluate the toxicity of patients with previously untreated CLL treated with FCR-Lite plus lenalidomide, followed by lenalidomide. The second is to evaluate the overall response rate and overall survival of patients with previously untreated CLL treated with FCR-Lite plus lenalidomide followed by lenalidomide. The third is to determine whether adding lenalidomide as a consolidationmaintenance therapy will eliminate bone marrow minimal residual disease in CR patients and whether patients who have a PR after 6 cycles of FCR-Lite plus lenalidomide will respond to 12 months of lenalidomide. The final secondary objective is to determine whether the expression of ZAP-70, CD38, and chromosomes correlate with response rate, duration of response, and survival for previously untreated patients with CLL.
