Hypercholesterolemia
Conditions
Brief summary
Primary Objective: To assess the safety and tolerability of ascending single doses of subcutaneously (SC) administered alirocumab (SAR236553/REGN727) in Japanese healthy male subjects. Secondary Objectives: * To assess the pharmacodynamics effect of a single SC dose of alirocumab on serum low-density lipoprotein cholesterol (LDL-C) and other lipids and apolipoproteins such as total cholesterol, high-density lipoprotein cholesterol (HDL-C), non-high-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, Triglycerides, Apolipoprotein B, Apolipoprotein A1 and Lipoprotein(a). * To assess the Pharmacokinetic profile of a single SC dose of alirocumab. * To assess the immunogenicity of a single SC dose of alirocumab.
Detailed description
4 sequential dose cohorts. Single dose followed by a total observation period of 15 weeks (106 days) for each participant.
