Clinical Trial Summary

This phase IIa study is to identify the efficacy and safety of IC(intracoronary) and IV(Intravenous) administrations of UMSC01 in patients with STEMI . This product is a new cell therapy product for treating AMI and produced by Ever Supreme Bio Technology Co., Ltd in Taiwan. The previous Phase I, open-label, single arm, single center study was conducted to evaluate the safety and to explore the efficacy of UMSC01 in subjects with STEMI via intracoronary administration followed by intravenous infusion. This first-in-human Phase I study of UMSC01 was completed on August 2nd, 2021. Among 8 subjects enrolled, no subjects experienced treatment-related TEAEs.


Description:

This is a two-stage Phase IIa, dose escalation followed by randomized, open-label, controlled with standard treatment, parallel-group study to evaluate the efficacy and safety of allogeneic umbilical cord mesenchymal stem cell, UMSC01, as an add-on treatment in subjects with STEMI. Subjects should present typical ischemic chest pain within 12 hours after symptoms onset and are diagnosed acute STEMI. Subjects should have undergone standard-of-care for STEMI, the immediate reperfusion management should include primary percutaneous coronary intervention (PCI), aspiration thrombectomy, and adjunctive antithrombotic therapy within 12 hours after the onset of symptoms. This study aims to treat eligible subjects with UMSC01 as an add-on stem cell therapy along with standard-of-care for STEMI. The investigational product (IP), UMSC01, will be applied to subjects via intracoronary (IC) infusion on the 4th - 5th day after the onset of the heart attack, followed by intravenous (IV) infusion 2 days after the IC infusion.
