Safety Evaluation of 3K3A-APC in Ischemic Stroke

Summary

The purpose of this study was to evaluate the safety, pharmacokinetics (PK) and preliminary efficacy of multiple ascending intravenous doses of 3K3A-APC, a Recombinant Variant of Human activated protein C (APC), in in the treatment of acute ischemic stroke following treatment with recombinant tissue plasminogen activator (tPA), mechanical thrombectomy or both.
