Clinical Trial Summary

TECNO is a multicenter, prospective, randomized, open label, blinded endpoint (PROBE) proof-of-concept trial evaluating if additional administration of intra-arterial Tenecteplase (TNK) improves reperfusion in patients with incomplete mechanical thrombectomy (MT). For this purpose, 156 adult participants experiencing an acute ischemic stroke due to a large vessel occlusion with incomplete reperfusion with residual occlusions after MT will be randomly assigned to receive 3mg intra-arterial (IA) TNK or best medical treatment. Recruitment will occur at 20 academic tertiary stroke care centers in Switzerland, Spain, Belgium, and Germany and patients are followed up for 90 days after the index event. Showing superiority for reperfusion outcomes would have a major impact on the future management of stroke patients.
