Phase I/II Study of CAMPATH in Patients With Relapsing or Refractory Non-Hodgkin's Lymphoma

This study is being conducted in 2 parts with the primary objective of part 1 being to determine the maximum tolerated dose (MTD) of CAMPATH (alemtuzumab, MABCAMPATH, CAMPATH) administered intravenously (IV) once a week as treatment for relapsing or refractory non-Hodgkin's lymphoma (NHL). The primary objective of part 2 is to determine the overall response rate (complete response, CR/unconfirmed , plus partial response) of weekly IV CAMPATH in the treatment of relapsing or refractory NHL. This is a Phase I/II study, open-label, multicenter study to evaluate the efficacy and safety of weekly IV CAMPATH as therapy for patients with relapsing or refractory non-Hodgkin's lymphoma.
