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 Clemizole HCl, or Placebo. The registry lists allocation as randomized. This is a multicenter, Phase 3, randomly assigned, neither you nor the study doctors know who gets the real treatment, compared with a dummy treatment study designed to measure the how well it works and safety of clemizole hydrochloride (EPX-100) as added on top of your current treatment therapy in children and adult participants with Dravet syndrome (DS).
They plan to enroll about 150 people at 86 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
