Summary
The NIH registered a new observational study (NCT07536074) titled EXTEND-IVT Registry on ClinicalTrials.gov. The study will evaluate the effectiveness and safety of intravenous thrombolysis administered beyond 4.5 hours after last known well in patients with acute ischemic stroke. The prospective, multicenter, observational cohort study will be conducted in routine clinical practice settings across China.
What changed
The EXTEND-IVT Registry (NCT07536074) has been registered as a prospective, multicenter, observational cohort study on ClinicalTrials.gov. The study focuses on evaluating intravenous thrombolysis administered beyond 4.5 hours after last known well in patients with acute ischemic stroke, examining both effectiveness and safety in routine clinical practice settings in China.
For healthcare providers and clinical researchers, this registry represents an observational study documenting real-world outcomes of extended-window thrombolysis treatment protocols. The findings may inform future clinical practice guidelines regarding stroke treatment time windows, though this study registration itself does not create immediate compliance obligations.
