Clinical Trial Summary

The purpose of this study is determine if 2 cycles of SGN-35 can be used instead of ICE prior to autologous stem cell transplant (ASCT) for relapsed and refractory HL. There are 2 steps to treating patients with relapsed or refractory HL. The first step is to shrink the lymphoma with chemotherapy. The chemotherapy regimen commonly used is called ICE. ICE is a combination of chemotherapy drugs: ifosfamide, carboplatin, and etoposide. The second step of treatment is to give high doses of chemotherapy and radiation therapy followed by infusion of stem cells. This is called an ASCT. This study will focus on the first step of treatment for relapsed and refractory HL.

ICE chemotherapy can cause many side effects. We believe that there are patients who can receive less toxic treatments and still do well. We have learned from past studies that [18F]FDG-PET scans (which we will call "PET scans") can be used to predict who will do well after ASCT. PET scans are tests used to measure the metabolic activity of the disease. Patients without abnormal activity on their PET scan (negative PET scan) before ASCT are much more likely to be cured than those with activity on their PET scan (positive PET scan).

In this study, instead of beginning with ICE chemotherapy, the patient will receive a new drug called Brentuximab vedotin (SGN-35). SGN-35 is a type of drug called an antibody drug conjugate. SGN-35 has 2 parts; a part that targets cancer cells (the antibody) and a cell killing part (the chemotherapy). The antibody part of SGN-35 sticks to a target called CD30. CD30 is an important molecule on some cancer cells (including Hodgkin lymphoma) and some normal cells of the immune system. The cell killing part of SGN-35 is a chemotherapy called monomethyl auristatin E (MMAE).

It can kill cells that the antibody part of SGN-35 sticks to.

Compared to ICE chemotherapy, SGN-has fewer side effects and does not require inpatient admission for treatment. We aim to determine whether patients can avoid treatment with ICE prior to ASCT. We will use the results of the PET scan to determine whether the patient needs additional chemotherapy before ASCT. If the PET scan is negative, the patient will be referred to ASCT and not receive ICE chemotherapy. If the PET scan is positive, the physician will discuss further treatment options with the patient.

Exclusion Criteria:

• Received more than 1 prior treatment (combined modality therapy represents 1 treatment) for Hodgkin Lymphoma

• Hepatitis B surface antigen positive or hepatitis B core antibody positive.

• Known pregnancy or breast-feeding.

• Medical illness unrelated to Hodgkin's Lymphoma, which, in the opinion of the attending physician and/or principal investigator, makes participation in this study inappropriate.

Intervention

Drug:
• brentuximab vedotin (SGN-35)
Patients will receive 2 cycles of weekly brentuximab vedotin, 1.2mg/kg on days 1, 8, and 15 of each 28 day cycle. Patients with pre-treatment positive bone marrow biopsies will have repeat bone marrow biopsies if the PET scan is negative. FDG-PET/CT will be repeated after 2 cycles of treatment within 1 week of the last dose of cycle 2. Patients with persistent abnormalities on FDG-PET/CT following 2 cycles of brentuximab vedotin will receive 2 cycles of augmented ICE. The first cycle of augmented ICE will be initiated 7-14 days after the last dose of SGN-35. FDG-PET/CT will be repeated within 7-14 days following the second cycle of augmented ICE. Stem cell mobilization can be performed following the first or second cycle of augmented ICE.
• Brentuximab Vedotin (SGN-35)
Patients will receive 2 cycles of weekly brentuximab vedotin, 1.2mg/kg on days 1, 8, and 15 of each 28 day cycle. FDG-PET/CT will be repeated after 2 cycles of treatment within 1 week of the last dose of cycle 2. Patients with pre-treatment positive bone marrow biopsies will have repeat bone marrow biopsies if the PET scan is negative. Patients with normalization of FDG-PET/CT and negative bone marrow biopsies following 2 cycles of brentuximab vedotin will undergo stem cell mobilization in preparation for ASCT.
