Brief summary
This randomized clinical trial will evaluate whether starting bempedoic acid in addition to high-intensity statin therapy and ezetimibe within 72 hours after percutaneous coronary intervention improves low-density lipoprotein cholesterol (LDL-C) control in adults with acute coronary syndrome. Participants will receive either triple therapy with a high-intensity statin, ezetimibe, and bempedoic acid or standard dual therapy with a high-intensity statin and ezetimibe for 12 weeks. The primary outcome is the proportion of participants with LDL-C below 55 mg/dL at Week 12. Changes in lipid and inflammatory markers, medication adherence, and treatment-emergent adverse events will also be assessed.
Detailed description
EARLY-BIRD ACS is a prospective, randomized, open-label, blinded-endpoint, parallel-group clinical trial in adults with acute coronary syndrome who have undergone percutaneous coronary intervention (PCI). Eligible participants with baseline LDL-C of at least 70 mg/dL will be randomized 1:1 within 72 hours after PCI. The experimental group will receive bempedoic acid 180 mg once daily, ezetimibe 10 mg once daily, and either atorvastatin 40 mg once daily or rosuvastatin 20 mg once daily. The active-comparator group will receive ezetimibe 10 mg once daily and either atorvastatin 40 mg once daily or rosuvastatin 20 mg once daily. Treatment will continue for 12 weeks. Follow-up assessments will occur at Week 4 and Week 12. Laboratory measurements will be performed using standardized methods in certified hospital laboratories. The primary analysis will use the intention-to-treat population.
Interventions
Bempedoic acid 180 mg tablet taken orally once daily for 12 weeks.
Ezetimibe 10 mg tablet taken orally once daily for 12 weeks.
Atorvastatin 40 mg orally once daily or rosuvastatin 20 mg orally once daily for 12 weeks, selected according to clinical judgment and routine practice.
