Intra-arterial TNK Following Endovascular Thrombectomy in Patients With Large Vessel Occlusion of Posterior Circulation

Acute Ischemic Stroke Clinical Trial

Official title:
Trial of Intra-arterial Tenecteplase Following Successful Endovascular Thrombectomy on Safety and Efficacy in Patients With Large Vessel Occlusion of Posterior Circulation - a Multicenter Randomized Clinical Trial (ATTENTION IA)

Clinical Trial Summary

Rationale: Recently, one prospective multicenter RCT reported a potential beneficial effect of intra-arterial alteplase following successful endovascular thrombectomy (EVT) in patients with an acute intracranial large vessel occlusion. In 2018, another prospective multicenter RCT supported the superiority of tenecteplase over alteplase in ischemic stroke patients with large vessel occlusion. Objective: To assess the effect of EVT in addition to intra-arterial tenecteplase compared to EVT alone, in patients with large vessel occlusion of posterior circulation, on functional and safety outcomes. Study design: This is a parallel group, randomized clinical trial of EVT with IA-TNK versus EVT. The trial has observer blind assessment of the primary outcome and of neuro-imaging at baseline and follow-up. Study population: Patients with acute intracranial large vessel occlusion of posterior circulation and an eTICI 2b-3 after EVT. Main study parameters/outcomes: The primary effect parameter will be excellent functional status at day 90 defined as a modified Rankin Score (mRS) of 0-1. The estimate will be adjusted for the known prognostic variables age, pre-stroke mRS, time from onset to randomization, stroke severity (NIHSS) and collaterals and adjusted and unadjusted estimates with corresponding 95% confidence intervals will be reported.
