Clinical Trial Summary

Multi-center, randomized, parallel-group, superiority study to compare the efficacy of adjunct intra-arterial rt-PA versus not adjunct intra-arterial rt-PA in the improvement of the efficacy of mechanical thrombectomy in patients with large vessel occlusion acute ischemic stroke.


Clinical Trial Description

The study objective is to validate whether the administration of intra-arterial rt-PA is efficient as an add-on to mechanical thrombectomy in patients with acute ischemic stroke and complete or near-complete recanalization of a proximal vessel occlusion and successful brain reperfusion on cerebral angiogram (corresponding to modified treatment in cerebral infarct (mTICI) score 2b/3). Patients with symptomatic large vessel occlusion (LVO) in the anterior circulation treated with MT resulting in a mTICI score 2b/3 on cerebral angiography will be enrolled in the angiosuite by interventionalists or neurologists once a mTICI 2b/3 is confirmed on cerebral angiography. Each included patient will be followed up to 90 days from the stroke. The primary outcome is the proportion of patients with microvascular hypoperfusion on CT Perfusion at 36±24h. The key secondary outcome is the proportion of patients with a mRS 0 to 1 at 90 days ;
