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 Alteplase, or Endovascular thrombectomy. The registry lists allocation as randomized. The NEWLINE trial is a multicenter, randomly assigned, open-label, blinded endpoint (PROBE) trial evaluating whether added on top of your current treatment low-dose intra-arterial alteplase administered immediately after successful endovascular thrombectomy improves functional outcomes in adults with acute ischemic stroke due to anterior circulation large vessel occlusion.
They plan to enroll about 416 people at 13 sites. Taking part typically means taking a study drug (or dummy pill), using or being fitted with a device plus check-ins.
