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 CYB003, or Psychological Support. The registry lists allocation as randomized. This study wants to determine the how well it works, whether it is safe and how hard side effects are to live with of CYB003 compared to matching dummy treatment (placebo) as added on top of your current treatment treatment in patients with major depression.
They plan to enroll about 330 people at 79 sites. Taking part typically means taking a study drug (or dummy pill), following a program (exercise, therapy, diet, or an app) plus check-ins.
