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 14-day remote ischemic conditioning, 30-day remote ischemic conditioning, or Endovascular thrombectomy. The registry lists allocation as randomized. For patients with acute ischemic stroke caused by large vessel occlusion, endovascular thrombectomy has been demonstrated to be the most effective therapy, as approximately 90% of the occluded vessels can be recanalized.
They plan to enroll about 2,105 people at 70 sites. Taking part typically means taking a study drug (or dummy pill), using or being fitted with a device, a procedure as part of the study plus check-ins.
