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 Eptinezumab, or Placebo. The registry lists allocation as randomized. Most individuals with mild traumatic brain injury (mTBI) experience post-traumatic headaches (PTH).
They plan to enroll about 80 people at Toronto. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
