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. * Patients with symptomatic cardiac disease including ventricular dysfunction, coronary artery disease, or arrhythmias * Patients with symptomatic brain metastases requiring treatment * Patients who are pregnant or breastfeeding * Patients with any serious underlying medical condition that would impair their ability to receive or tolerate the planned treatment * Patients with dementia or altered mental status that would preclude understanding and rendering of informed consent
