What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
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 ITI-1284 10 mg, ITI-1284 20 mg, or Placebo. The registry lists allocation as randomized. This is a multicenter, randomly assigned, neither you nor the study doctors know who gets the real treatment, compared with a dummy treatment study evaluating the how well it works, safety, and tolerability of ITI-1284 compared with dummy treatment (placebo) as added on top of your current treatment therapy to GAD treatment in patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) criteria for GAD who have an inadequate response to ongoing GAD treatment.
They plan to enroll about 705 people at 59 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
