1. Patients with HL who have received ASCT in the previous 30-45 days.
2. Patients at high risk of residual HL post ASCT as indicated by at least one of the following:
- History of refractory HL (defined as patients progressing on or failing to achieve a complete remission following frontline standard chemotherapy (6 to 8 cycles) or a combined modality treatment program)
- Relapsed or progressive HL that occurs <12 months from the end of frontline standard chemotherapy or a combined modality treatment program
- Extranodal involvement at the time of pre-ASCT relapse (including extranodal extension of nodal masses into adjacent vital organs)
3. Histologically-confirmed HL.
4. Age greater than or equal to 18 years.
5. An Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
6. The following required baseline laboratory data: absolute neutrophil count (ANC) >=1000/microL, platelets >=50,000/microL (unsupported), bilirubin =<1.5X upper limit of normal (ULN) or =<3X ULN for patients with Gilbert´s disease, serum creatinine =<1.5X ULN, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =<2.5X ULN.
7. Females of childbearing potential must have a negative serum or urine beta-hCG pregnancy test result within 7 days prior to the first dose of SGN-35. Females of non-childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy.
8. Both females of childbearing potential and males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 30 days following the last dose of study drug.
