Official title: Early Initiation of Tafolecimab for Patients With Acute Coronary Syndromeundergoing Percutaneous Coronary Intervention in Chinese Population (EMPACT): A Randomized Controlled Trial

Status Not yet recruiting

Clinical Trial Summary

For patients with ACS undergoing PCI, intensive lipid-lowering including PCSK9 monoclonal antibody should be started as soon as possible, that is, lower LDL-C level should be achieved as soon as possible. Compared with conventional lipid-lowering regimen, it is expected that the occurrence of major adverse cardiovascular events can still be reduced after drug discontinuation. Therefore, the optimization strategy of "for patients with ACS undergoing PCI, intensive lipid-lowering with PCSK9 monoclonal antibody can be started as soon as possible" is proposed.

Clinical Trial Description

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death worldwide, and its incidence is increasing yearly in China, which has not yet reached the inflection point. Acute coronary syndrome (ACS) is a severe form of ASCVD, and lipid-lowering and antithrombotic therapy are the two core therapies. In the latest ESC/EAS guidelines for lipid management, for ACS patients, the target LDL-C is <1.4 mmol/L and ≥50% reduction from baseline, and specific initiatives to achieve this target are proposed, emphasizing the timing of clinical application and status of the novel lipid-lowering agent-proprotein convertase subtilisin/kexin type 9 monoclonal antibody (PCSK9) (hereafter referred to as PCSK9 antibody). In recent years, large-scale randomized controlled trials and outcomes of PCSK9 antibodies have demonstrated that PCSK9 antibodies further reduce adverse cardiovascular events by significantly lowering LDL-C levels under the background statin (±cholesterol absorption inhibitor ) therapy. The introduction of PCSK9 antibodies allowed for the reduction of LDL-C to unprecedented levels. From the "cholesterol principle" perspective, it is theoretically reasonable to add a PCSK9 inhibitor to statins as soon as possible during hospitalization for ACS patients. Still, there is no clear evidence from large RCTs. Current evidence supports that for ACS patients, PCSK9 antibodies could be used only when LDL-C is still not up to standard based on treatment with the maximum tolerable dose of statins during the first 2-3 months. However, the immediate initiation of PCSK9 antibodies during the acute phase of ACS (before hospital discharge) has yet to be studied. ;
