Summary
A multicenter, prospective, open-label, blinded endpoint, randomized controlled trial aiming at evaluating the efficacy and safety of intra-arterial recombinant human tissue plasminogen activator (rt-PA) after successful recanalization of acute large vessel occlusion in the anterior circulation by mechanical thrombectomy in improving the 90-day functional outcome.

Outcome
Met primary endpoint
paper The proportion of patients with a modified Rankin Scale score of 0 or 1 at 90 days was 44.8% (73/163) in the intra-arterial alteplase group vs 30.2% (48/159) in the standard treatment group PMID 42262770 ↗
paper intra-arterial alteplase resulted in a higher likelihood of excellent outcomes at 90 days. PMID 42262770 ↗
