Summary
Brief summary
The primary objective of this study was to evaluate the effect of 24 weeks of evolocumab
administered subcutaneously (SC) every month, compared with ezetimibe, on low-density
lipoprotein cholesterol (LDL-C) levels in adults with high cholesterol who are unable to
tolerate an effective dose of a statin due to muscle-related side effects (MRSE).
