Effect of Evolocumab Added to Moderate-Intensity Statin Therapy on LDL-C Lowering and Cardiovascular Adverse Events in Patients With Acute Coronary Syndrome

Overview

The study is an open-label, multicenter, and randomized study(five hospitals).The purpose of this study is to assess the differences in the effects of the evolocumab added to moderate-intensity statin therapy and the moderate-intensity statin only therapy on the regulation of LDL-C levels in patients with acute phase acute coronary syndrome after four weeks of treatment. The primary outcome is the percentage change in LDL-C in weeks 4 and week 12 after treatment. The secondary outcome is the occurrence of MACE after 12 weeks and 1 year of treatment.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Double (Investigator, Outcomes Assessor)
  • Study Primary Completion Date: June 1, 2022

Interventions

  • Drug: Evolocumab
    • Patients were randomly assigned of the ratio of 1:1 using a computer-generated random number and divided into two treatment groups: the statin alone therapy and the evolocumab plus statin therapy.

Arms, Groups and Cohorts

  • Experimental: the evolocumab plus statin therapy
    • Patients with ACS are treated with atorvastatin (20mg) daily and evolocumab (140 mg) every two weeks throughout the study period
  • No Intervention: the statin alone therapy
    • Patients with ACS are treated with atorvastatin (20mg) daily throughout the study period.

Prior to the study, patients who received intensive statins for more than 4 weeks (the same dose of statin therapy has been sustained for the past four weeks) with LDL-C levels ≥70 mg/dL (≥1.8 mmol/L) or non-HDL-C ≥100 mg /dL (≥2.6mmol/L) are included in the study; 2. Prior to the study, patients who received moderate-intensity statin therapy for more than 4 weeks (the same dose of statin therapy has been sustained for the past four weeks) with LDL-C levels ≥90 mg/dL (≥2.3 mmol/L) or non-HDL-C≥ 120mg/dL (≥3.1mmol/L) are included in the study; 3. Prior to the study, patients who do not receive statin therapy or who do not continue to receive statin with LDL-C ≥ 125 mg/dL (≥ 3.2 mmol/L) or non-HDL-C ≥ 155 mg/dL (≥ 4.0 mmol/L). – Being able to understand research requirements and sign informed consent Exclusion Criteria:
