Safety of Adjunctive Intraarterial Tenecteplase Following Mechanical Thrombectomy: The ALLY Pilot Trial | Stroke
BACKGROUND: Recent studies suggest that the use of adjunctive intraarterial alteplase after mechanical thrombectomy (MT) may improve outcomes; however, there are limited data on the use of intraarterial tenecteplase, a newer-generation lytic, in this acute ischemic stroke patient population. Here, we evaluate the use of intraarterial tenecteplase in the ALLY pilot study (Adjunctive Intraarterial Tenecteplase Following Mechanical Thrombectomy). METHODS: ALLY was a prospective, single-center, nonrandomized pilot study assessing the feasibility and safety of intraarterial tenecteplase up to 4.5 mg in acute ischemic stroke-large vessel occlusion MT patients with incomplete recanalization. The primary safety end point was any intracranial hemorrhage and neurological worsening by ≥4 points on the National Institutes of Health Stroke Scale within 24 hours of treatment with intraarterial tenecteplase. A post hoc analysis was performed with a control cohort of MT patients (ALLY MT) not receivin
