The overall goal of this study is to compare the effects, good and/or bad of the study drugs brentuximab vedotin and nivolumab (Bv-NIVO) against the standard therapy of chemotherapy with or without radiation for people with Hodgkin Lymphoma (HL) to find out which is better.
Treatment with brentuximab vedotin and nivolumab (Bv-NIVO) is considered investigational, which means it has not yet been approved by the U.S. Food and Drug Administration (FDA).
