|Primary Completion Date:||August 2012 (Final data collection date for primary outcome measure)|
For all patients enrolled, the study will begin with a stepped-up schedule of single agent Alemtuzumab given subcutaneously (SQ) on week #1. Dose escalation will occur during the first week of therapy, starting with 3 mg of Alemtuzumab administered SQ on day 1. If well tolerated, this will be followed by 10 mg SQ on day 3 and 30 mg (split into 2 injection sites) on day 5. Plasma samples will be obtained for Alemtuzumab pharmacokinetics (PK) during the first week of single agent Alemtuzumab stepped up dosing and subsequently before and after the 5th and the 8th Alemtuzumab/CHOP dose
CHOP will be given 60-120 minutes following SQ administration of Alemtuzumab as follows: cyclophosphamide 750 mg/m2 IV on day 1, doxorubicin 50 mg/m2 IV on day 1, vincristine 1.4 mg/m2 (maximum dose = 2 mg) IV on day 1, and prednisone 100 mg PO on days 1-5.

Other Name: Humanized monoclonal antibodyProcedure: Plasma Samples
Plasma samples will be obtained for Alemtuzumab pharmacokinetics (PK) during the first week of single agent Alemtuzumab stepped up dosing and subsequently before and after the 5th and the 8th Alemtuzumab/CHOP dose.
Rationale: The drug combination called CHOP, or Cyclophosphamide (Cytoxan), Doxorubicin (Adriamycin), Vincristine (Oncovin), and Prednisone (Deltasone), has been used against different types of lymphoma for many years. Researchers are investigating what other therapies to combine with the CHOP regimen to improve outcomes for patients with lymphoma. The current study combines CHOP with alemtuzumab, a monoclonal antibody used against leukemia. Monoclonal antibodies are a type of immunotherapy used against some types of cancer. They are produced in a laboratory and designed to target as well as bind with cells that carry specific proteins. Alemtuzumab is designed to target leukemia cells that express a specific protein. The specific protein recognized by alemtuzumab is the CD52 antigen. This antigen, or substance that causes the immune system to create a specific response, is expressed on normal B and T cells, as well as on abnormal T cells characteristic of certain cancers. Alemtuzumab causes the CD52 antigen to bind with B-cell lymphocytes. This study will also assess the theory that alemtuzumab may increase the effectiveness of the chemotherapy agents included in the CHOP regimen.
Treatment: Patients in this study will receive alemtuzumab and CHOP. Alemtuzumab will be given through injections into the skin and CHOP will be administered through intravenous infusions. Patients will receive alemtuzumab alone during the first week of the study. An increasing amount of alemtuzumab will be given during the first week. If patients cannot tolerate the highest amount of alemtuzumab determined as appropriate within one week, they will be removed from the study. Once the highest dose of alemtuzumab has been achieved, patients will then receive both alemtuzumab and CHOP every three weeks. This schedule will be repeated up to eight times. Several tests and exams will be given throughout the study to closely monitor patients. Treatments will be discontinued due to disease growth or unacceptable side effects.
