New treatment option for Acute Ischemic Stroke
Official title Phase III Clinical Trial of rhTNK-tPA in Treating Acute Ischemic Stroke With Extended Time Window.
ClinicalTrials.gov ID: NCT07201688
What this study is testing
What is rhTNK-tPA?
rhTNK-tPA is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for acute ischemic stroke.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study designed to evaluate the efficacy of recombinant human tissue-type plasminogen activator variant (rhTNK-tPA) (0.25 mg/kg, maximum dose 25 mg) compared with placebo in patients with acute large vessel occlusive stroke who present within 4.5 to 24 hours of symptom onset. The study plans to enroll patients with acute large vessel occlusive stroke who present within 4.5 to 24 hours of symptom onset (including wake-up strokes and strokes without witnesses).
- Phase 3: a large, late-stage study
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
