一项评估SGC001在前壁ST段抬高型心肌梗死患者中疗效和安全性的研究
一项随机、双盲、安慰剂对照的II期临床研究,旨在评估SGC001注射液在中国前壁ST段抬高型心肌梗死患者中计划进行直接经皮冠状动脉介入治疗(pPCI)时的疗效、安全性和药代动力学特征

详细说明
The study drug will be administered intravenously within 6 hours of the onset of acute myocardial infarction symptoms, on top of standard of care.
The primary efficacy endpoint is the percentage of myocardial infarction size on Day 4 post-dosing, assessed by cardiac magnetic resonance (CMR) imaging.
Secondary endpoints include myocardial infarction size at Day90, microvascular obstruction area and left ventricular function parameters at Day4 and Day90, myocardial salvage index at Day4, biomarkers (hs-TnI, hs-CRP, CK-MBmass, NT-proBNP), and composite incidence of cardiovascular death or heart failure events within 90 days. Safety assessments include adverse events, serious adverse events, physical examinations, vital signs, ECGs, and laboratory tests. Participants will undergo follow-up visits at Days 30 and 90, with a telephone follow-up at Day 180 to record survival status and heart failure events.
