Ischemic Stroke Clinical Trial
Official title:
A Phase 3 Study to Evaluate the Efficacy and Safety of 3K3A-APC in Combination With Tissue Plasminogen Activator, Mechanical Thrombectomy, or Both in Subjects With Moderate to Severe Acute Ischemic Stroke
The purpose of this study is to evaluate the efficacy and safety of intravenous doses of 3K3A-APC, a recombinant variant of human activated protein C (APC), in the treatment of acute ischemic stroke following treatment with thrombolysis, mechanical thrombectomy or both.
This multicenter, randomized, placebo-controlled, double-blind, Phase 3 study is being performed in coordination with StrokeNet to evaluate efficacy and safety of 3K3A-APC following administration of thrombolysis, mechanical thrombectomy, or both in subjects with moderate to severe acute ischemic stroke. The study will be conducted in two phases. During a lead-in dose-finding phase, a maximum of 360 subjects will be randomized to 3K3A-APC or placebo using a Bayesian adaptive approach. Randomized subjects will receive 3K3A-APC or placebo every 12 hours for up to 5 doses (approximately 3 days) or until discharge from the hospital (whichever occurs first). The lead-in phase will transition to one selected 3K3A APC dose-and recruitment will continue-when a single dose proves superior to all other doses and safe. The definitive phase will continue with the selected dose of 3K3A-APC from the lead-in phase. Randomization will be stratified on 4 variables. Lead-in patients who received the dose selected for the definitive phase will be included in the final data analysis. ;
