Brentuximab is an antibody-drug conjugate (ADC), which is the combination of an antibody (a protein that binds to cells) and a chemotherapy molecule. Brentuximab works by using the antibody portion to enter into the Hodgkin lymphoma cells and then releasing the chemotherapy portion, which attempts to destroy the cell. The intravenous chemotherapy drugs Adriamycin, Vinblastine and Dacarbazine (AVD) which you will receive in this research study are approved for use in people with Hodgkin Lymphoma. A drug called bleomycin is usually included with AVD, but since it appears to be a less effective drug with significant potential risks, it is being replaced in this study with the drug brentuximab. In this research study, the investigators are looking to see whether brentuximab in combination with AVD is effective in treating limited-stage Hodgkin Lymphoma.
