What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Biospecimen Collection, Bleomycin Sulfate, or Brentuximab Vedotin. The registry lists allocation as randomized. This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma.
They plan to enroll about 1,875 people at 419 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic, a procedure as part of the study plus check-ins.
