A copy of the signed informed consent form will be retained in the patient's chart. Patients must meet baseline lab data requirements. Exclusion Criteria: Patients with primary cutaneous ALCL Patients who have been treated previously with any anti-CD30 antibody Patients who have received any mAb unless a recent serum testing reveals no antibody titer and no evidence of human anti-murine antibodies (HAMA) or human anti-chimeric antibodies (HACA) in the peripheral circulation Patients receiving any investigational biological agent within eight weeks of enrollment or any other investigational agent within four weeks of enrollment Patients with a known hypersensitivity to recombinant proteins or any excipient contained in the drug formulation Patients with a history of other malignancies during the past five years with the exception of adequately treated basal or squamous cell skin cancer or cervical carcinoma in situ Patients with known active viral, bacterial, or systemic fungal infection; patients who are known to be HIV, Hepatitis B, or Hepatitis C positive.
