GLobal Assessment of Plaque reGression With a PCSK9 antibOdy as Measured by intraVascular Ultrasound (GLAGOV)

February 1, 2019 updated by: Amgen

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

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.

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Percent Atheroma Volume at Week 78
Time Frame: Baseline and week 78
Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. The extent of atherosclerosis was expressed as percent atheroma volume (PAV) in a ≥ 40 mm segment of one targeted (imaged) coronary artery, calculated as the percentage of the total vessel volume occupied by atheroma.
Baseline and week 78

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Total Atheroma Volume at Week 78
Time Frame: Baseline and week 78
Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. Total atheroma volume (TAV) in a ≥ 40 mm segment of the targeted coronary artery was calculated as the average plaque area over the number of images that were evaluated by IVUS multiplied by the median vessel length to compensate for differences in segment length between participants.
Baseline and week 78
Percentage of Participants With Regression in Percent Atheroma Volume
Time Frame: Baseline and week 78

Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. The extent of atherosclerosis was expressed as percent atheroma volume (PAV) in a ≥ 40 mm segment of one targeted (imaged) coronary artery, calculated as the percentage of the total vessel volume occupied by atheroma.

Regression in PAV was defined as any reduction from baseline in PAV.

Baseline and week 78
Percentage of Participants With Regression in Total Atheroma Volume
Time Frame: Baseline and week 78

Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. Total atheroma volume (TAV) in a ≥ 40 mm segment of the targeted coronary artery was calculated as the average plaque area over the number of images that were evaluated by IVUS multiplied by the median vessel length to compensate for differences in segment length between participants.

Regression in TAV was defined as any reduction from baseline in TAV.
