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 Brenipatide, or Placebo. The registry lists allocation as randomized. This study evaluates the safety and how well it works of brenipatide when administered with standard of care (SoC) compared to dummy treatment (placebo) plus SoC in delaying the return of major depressive symptoms.
They plan to enroll about 1,000 people at 180 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
