A Clinical Study of MT1002 in Subjects With Acute Coronary Syndrome Undergoing PCI

Phase 2

Recruiting

• Conditions: Acute Coronary Syndrome
• Interventions: Drug: MT1002 Injection

• Registration Number: NCT06533358
• Lead Sponsor: Shaanxi Micot Technology Limited Company

Brief Summary

An Open-label, Sequential Dose Escalation/De-escalation Clinical Trial of MT1002 in Subjects With Acute Coronary Syndrome Undergoing PCI.

Detailed Description

MT1002 is a novel 32-amino acid synthetic peptide aimed to combine molecular functions of both a direct thrombin inhibitor and a platelet glycoprotein IIb/IIIa receptor antagonist, indicated for use as an antithrombotic and anticoagulant in patients with ACS and in patients undergoing PCI.

This study is an Open-label, sequential dose escalation/de-escalation clinical trial of MT1002 in subjects with acute coronary syndrome undergoing PCI. First dose cohort is 0.60 mg/kg (initial loading dose, intravenous bolus) + 1.2 mg/kg/h\*4 h (maintenance dose, intravenous infusion). The Safety Review Committee makes decisions on subsequent dose adjustments. Dose escalation/de-escalation and stopping rules have been put in place to ensure the safety of the patients in this study.
