Brief Summary: RATIONALE Monoclonal antibodies such as alemtuzumab and 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 Giving alemtuzumab together with rituximab may kill more cancer cells

PURPOSE This phase II trial is studying the side effects and how well giving alemtuzumab together with rituximab works in treating patients with high-risk early-stage chronic lymphocytic leukemia
Detailed Description: OBJECTIVES

Primary

Determine the rate of complete and overall response to alemtuzumab and rituximab in patients with high-risk early-stage chronic lymphocytic leukemia
Determine the toxicity of this regimen in these patients Secondary
Determine the overall survival and time to progression of patients treated with this regimen
Determine time to response and duration of response in patients treated with this regimen
Correlate prognostic markers 11q- 17p- unmutated VH gene and CD38 with clinical outcome
Determine response to this regimen using an expanded definition of response that includes minimal residual disease detected by sensitive flow cytometry in patients in complete clinical remission and single rearranged IgVH gene detected by polymerase chain reaction in patients with no monoclonal population on flow cytometry
Correlate in vitro response with clinical outcome in patients treated with this regimen
Determine if alemtuzumab and rituximab are synergistic in vitro
Determine the mechanism of action of this regimen in vitro
Determine the effect of this regimen on immune function
Monitor T-lymphocyte natural killer cell and monocyte number during and after treatment in these patients
Serially evaluate T-lymphocyte immunophenotype and function in patients treated with this regimen
Monitor recovery of humoral immunity by serial serum protein electrophoresis immunofixation electrophoresis and immunoglobulin quantification

OUTLINE

Dose-escalation week 1 Patients receive rituximab IV on day 1 and escalating doses of alemtuzumab subcutaneously SC on days 3-5 in week 1
Treatment weeks 2-5 Patients receive alemtuzumab SC on days 1-3 at the highest dose administered during week 1 and rituximab IV on day 3 in weeks 2-5 in the absence of disease progression or unacceptable toxicity

Patients undergo blood collection at baseline and periodically during study treatment for pharmacokinetic and prognostic biomarker 11q- 17p- unmutated IgVH and CD38 expression by flow cytometry and fluorescent in-situ hybridization studies Immune function CDR3 T-cell receptor by reverse transcriptase-polymerase chain reaction and in vitro and in vivo response are also examined

After completion of study therapy patients are followed periodically for 5 years

PROJECTED ACCRUAL A total of 33 patients will be accrued for this study
