  Purpose
This study will evaluate whether low-density lipoprotein (LDL-C) lowering with evolocumab (AMG 145) results in greater change from baseline in percent atheroma volume (PAV) at week 78 than placebo in adults with coronary artery disease taking lipid lowering therapy.

Condition Intervention Phase
Hypercholesterolemia Biological: Evolocumab Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Multi-center, Placebo-controlled, Parallel-group Study to Determine the Effects of Evolocumab (AMG 145) Treatment on Atherosclerotic Disease Burden as Measured by Intravascular Ultrasound in Subjects Undergoing Coronary Catheterization

Ages Eligible for Study:   18 Years to 99 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Clinical indication for coronary angiography
  • Subjects already taking statin therapy, niacin or ezetimibe at screening must have been on a stable dose for at least 4 weeks prior to screening LDL-C. Subjects not taking lipid-regulating therapy must enter the study via a lipid stabilization period. Subjects who are intolerant to statins must meet statin intolerance entry criteria
  • Fasting LDL-C ≥ 80 mg/dL (2.07 mmol/L) with or without additional risk factors, or, LDL-C ≥ 60 -< 80 mg/dL (1.55-2.07 mmol/L) in the presence of one major or three minor risk factors

Subjects must meet the following criteria at the qualifying coronary catheterization procedure:

  • Evidence of coronary heart disease (at least one lesion in a native coronary artery that has > 20% reduction in lumen diameter) or prior percutaneous intervention (PCI)
  • Left main coronary artery < 50% reduction in lumen diameter by visual estimation
  • Target coronary artery for IVUS must be accessible to the IVUS catheter, must not have a > 50% reduction in lumen diameter within the target segment (and at least 40 mm in length); cannot have undergone prior PCI or coronary artery bypass graft (CABG) and is not a candidate for intervention over the next 18 months. It may not be a bypass graft, bypassed vessel or culprit vessel for previous myocardial infarction (MI).

Exclusion Criteria:

  • Coronary artery bypass graft surgery < 6 weeks prior to the qualifying IVUS
  • New York Heart Association (NYHA) III or IV heart failure, or last known left ventricular ejection fraction less than 30%
  • Uncontrolled cardiac arrhythmia that is not controlled by medications in the 3 months prior to randomization
  • Known hemorrhagic stroke
  • Uncontrolled hypertension at randomization
  • Fasting Triglycerides ≥ 400 mg/dL (4.5 mmol/L) at screening
  • Type 1 diabetes or poorly controlled type 2 diabetes (hemoglobin A1c [HbA1c] > 9%) at screening.
  • Moderate to severe renal dysfunction (estimated glomerular filtration rate [eGFR] < 30 ml/min/1.73m²) at screening.
