New stroke drug tested in Real-World study – could it be safer?
NCT ID NCT05697575
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study collects data from 336 adults aged 18-85 who had an acute ischemic stroke and received a new clot-busting drug called non-immune staphylokinase. Researchers will check how often bleeding in the brain occurs and compare results to the standard drug alteplase. The goal is to see if the new drug is safer and works as well in everyday hospital settings.
