  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 subjects with coronary artery disease taking lipid lowering therapy.


Condition Intervention Phase
Hypercholesterolemia
Biological: Evolocumab (AMG 145)
Other: Placebo
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, 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.

Further study details as provided by Amgen:

Primary Outcome Measures:
  • Nominal change in PAV from baseline to week 78 post randomization, as determined by intravascular ultrasound (IVUS) [ Time Frame: 78 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Regression (any reduction from baseline) in PAV [ Time Frame: 78 weeks ] [ Designated as safety issue: No ]
  • Nominal change in total atheroma volume (TAV) from baseline to week 78 [ Time Frame: 78 weeks ] [ Designated as safety issue: No ]
  • Regression (any reduction from baseline) in TAV [ Time Frame: 78 weeks ] [ Designated as safety issue: No ]

Enrollment: 970
Study Start Date: May 2013
Estimated Study Completion Date: July 2016
Estimated Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
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 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 40mm in length); cannot have undergone prior PCI or 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 MI.

Exclusion Criteria:

  • Coronary artery bypass graft surgery < 6 weeks prior to the qualifying IVUS
  • 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 (HbA1c > 9%) at screening.
  • Moderate to severe renal dysfunction (eGFR < 30 ml/min/1.73m2) at screening.
