Recruitment Status : Completed

1. Evaluate the ability of Cyclophosphamide, Fludarabine, Alemtuzumab, and Rituximab (CFAR) to increase the proportion of patients with <5% CD5/CD19+ cells in bone marrow to 66% following 3 courses of treatment without significantly increasing the incidence of pneumonia or sepsis compared to a historic group of patients treated with the combination fludarabine, cyclophosphamide, and rituximab (FCR).
- Assess complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR.
- Evaluate molecular remission in bone marrow by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responders treated with CFAR.
- Assess immune parameters including blood T cell counts and subset distribution and serum immunoglobulin levels pretreatment, during treatment, and post-treatment in patients treated with CFAR.

- Overall Participant Response [ Time Frame: Evaluated after 3 courses of 4 week therapy (12 weeks) ]Overall Response: Complete remission (CR), nodular partial remission (nPR), and partial remission (PR) rates (overall response) in high-risk, previously untreated patients with CLL treated with CFAR. National Cancer Institute - Working Group (NCI-WG) response criteria. CR defined as zero nodes, Liver/spleen not palpable, zero symptoms, polymorphonuclear leukocyte (PMN)>1,500/uL, Platelets >100,000uL, Hemoglobin (untransfused) >11.0g/dL, Lymphocytes <4,000/uL and Bone Marrow Aspirate biopsy <30% lymphocytes with no lymphocyte infiltrate; PR defined as nodes >/= 50% decrease,Liver/spleen >/= 50% decrease, symptoms not applicable, PMN >1,500/uL or >50% improvement from baseline, Platelets 100,000uL or >/=50% decrease improvement from baseline, Hemoglobin (untransfused) >11.0g/dL or >50% improvement from baseline, Lymphocytes >50% decrease and Bone Marrow Aspirate biopsy Not Applicable for PR; with nPR defined same as PR but with <30% lymphocytes with residual disease on biopsy.
