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 Standard-dose intravenous tenecteplase, Low-dose intravenous tenecteplase, or No intravenous tenecteplase. The registry lists allocation as randomized. Stroke is causing 6.6 million deaths and is a major cause of disability worldwide in 2019.
They plan to enroll about 20,000 people at 2 sites. Taking part typically means taking a study drug (or dummy pill), a procedure as part of the study plus check-ins.
