2. Previously untreated classical Hodgkin lymphoma (i.e., nodular sclerosis, mixed cellularity, lymphocyte depleted, lymphocyte-rich, and not otherwise specified \[NOS\]).
3. Stage IIB, III, and IV disease by Ann Arbor classification.
4. Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2.
5. Patients must have bi-dimensional measurable disease documented in the lymphoma baseline tumor assessment form (PET-CT report) within 30 days prior to Screening (at least 1.5 cm)
6. Patients must have a bone marrow biopsy within 60 days prior to screening.
7. Patients must have a multi gated acquisition scan (MUGA) or echocardiogram within 60 days prior to study screening and the ejection fraction must be \>= 50%.
8. Adequate hematologic function, defined as Absolute neutrophil count (ANC) ≥ 1,500/mm3 / 1x109/L and Platelet count ≥75,000/mm3 / 75x109/L unless there is known marrow involvement of the disease
9. Serum Creatinine \< 2.0 mg/dl and/or creatinine clearance or calculated creatinine clearance \> 40 mL/minute.
10. Total Bilirubin \< 1.5 x the upper limit of normal (ULN) unless elevation is known to be due to Gilbert syndrome.
11. ALT or AST must be \< 3 x the upper limit of the normal range. AST and ALT may be elevated up to 5 times the ULN if their elevation can be reasonably ascribed to the presence of hematologic/solid tumour in liver.
12. Hemoglobin must be ≥ 8g/dL

Voluntary written informed consent must be signed before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.

Exclusion Criteria:

2. Previous treatment with BV or any other prior anti-CD30-based antibody therapy
3. Female patient who is both lactating and breast-feeding or has a positive pregnancy test during the screening period or a positive pregnancy test on Day 1 before the first dose of study drug
