The Safety and Tolerability After Intravenous Infusion of UMC119-06 in Subjects With Acute Ischemic Stroke.

UMC119-06-01

The clinical study with UMC119-06 is designed to investigate the safety in patients with acute ischemic stroke ("AIS"). This will be a dose escalation, open-label, single-center study in adult with acute ischemic stroke. UMC119-06 is ex vivo cultured human umbilical cord tissue-derived mensenchymal stem cells product which is intended for treatment of acute ischemic stroke.
