CHOP and Campath-1H in Previously Untreated Aggressive T/NK-Cell Lymphomas

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.

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.
