This is a phase 1, blinded-outcome, randomized, placebo controlled study to investigate the safety and feasibility of super-selective intra-arterial administration of verapamil and citicoline immediately following successful endovascular thrombectomy as a potential neuroprotective synergistic therapeutic strategy in emergent large vessel occlusion stroke. This trial represents the first time that citicoline will be evaluated in human subjects as a superselectively administered neuroprotective agent administered in an acute time frame as an adjunct to intra-arterial thrombectomy. Furthermore, it will represent the first trial to evaluate combinational therapy for acute stroke neuroprotection.
