Inclusion Criteria: 1. The subject has relapsed after achieving a complete response to treatment with KW 0761 for PTCL or CTCL on study, KW-0761-001. 2. The subject has an Eastern Cooperative Oncology Group (ECOG) performance status score of < 2 at study entry. 3. The subject is >18 years of age. 4. The subject has adequate hematological function: absolute neutrophil count [ANC] >1,500 cells/uL and platelets >100,000 cells/uL,except in patients with known bone marrow involvement where absolute neutrophil count [ANC] must be > 1,000 cells/uL and platelets >75,000 cells/uL. 5. The subject has adequate hepatic function: bilirubin ≤ 1.5 times the specific institutional upper limit of normal [ULN]; aspartate transaminase [AST] and alanine transaminase [ALT] each ≤ 2.5 x ULN or ≤ 5.0 x ULN in the presence of known hepatic malignancy. 6. The subject has serum creatinine ≤1.5 x ULN or a calculated creatinine clearance >60 mL/min. 7. Subjects with MF and a history of staphylococcus colonization are eligible provided they continue to receive stable doses of prophylactic antibiotics. Exclusion Criteria: The subject has received any type of treatment for their disease since completing study, KW-0761-001. The subject has a significant uncontrolled intercurrent illness including, but not limited to: uncontrolled infection requiring antibiotics; clinically significant cardiac disease (class III or IV of the New York Heart Association [NYHA] classification); unstable angina pectoris; angioplasty, stenting, or myocardial infarction within 6 months; uncontrolled hypertension (systolic blood pressure >160 mmHg, diastolic BP >100 mmHg, found on two consecutive measurements separated by a 1 week period) despite two anti-hypertensive medications; clinically significant cardiac arrhythmia; or uncontrolled diabetes. Subjects on any immunomodulatory drug, (other than low dose corticosteroids equivalent to a daily dose of 10 mg of prednisone The subject has a psychiatric illness, disability or social situation that would compromise the subject's safety or ability to provide consent, or limit his or her compliance with study requirements.
