Amgen
ClinicalTrials.gov Identifier:
NCT01375777
First received: June 16, 2011
Last updated: July 8, 2014
Last verified: July 2014
  Purpose

Primary hypothesis is that a dose regimen of evolocumab (AMG 145) when used as monotherapy will be well tolerated and will result in greater lowering of low density lipoprotein cholesterol (LDL-C) than placebo.


Condition Intervention Phase
Hyperlipidemia
Biological: evolocumab (AMG 145)
Other: Ezetimibe
Other: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Placebo and Ezetimibe Controlled, Dose-ranging Study to Evaluate Tolerability and Efficacy of AMG145 on Low Density Lipoprotein Cholesterol (LDL-C) in Hypercholesterolemic Subjects With a 10 Year Framingham Risk Score of 10% or Less

Primary Outcome Measures:
  • Percent change from baseline in low density lipoprotein cholesterol (LDL-C) after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Absolute change from baseline in low density lipoprotein cholesterol (LDL-C) after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in non-high density lipoprotein cholesterol (non-HDL-C) after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in apolipoprotein B (ApoB) after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in the total cholesterol/high density lipoprotein cholesterol (HDL-C) ratio after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Percent change from baseline in apolipoprotein B/apolipoprotein A1 (ApoB/ApoA1) ratio after 12 weeks of treatment [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
