This study is designed to assess pharmacokinetics and pharmacodynamics of evolocumab and alirocumab across an appropriate dose range to inform clinical trial operating characteristics for future clinical pharmacology pharmacodynamics similarity studies. This is a randomized, placebo-controlled, single-dose, parallel arm study in 72 healthy subjects assigned to one of four dose groups (low, intermediate low, intermediate high, and high) of each drug (evolocumab and alirocumab ) or placebo.

Subject tests positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by a molecular diagnostic test performed prior to admission. 15. Subject has known or suspected allergies or sensitivities to any study drug. 16. Subject has clinical laboratory test results (hematology, serum chemistry lipid panel and comprehensive metabolic panel) at Screening that are outside the reference ranges provided by the clinical laboratory and considered clinically significant by the investigator. 17. Subject has a positive test result at Screening for human immunodeficiency virus (HIV) 1 or 2 antibody, hepatitis C virus load, hepatitis C virus antibodies, or hepatitis B surface antigen. 18. Subject is unable or unwilling to undergo multiple venipunctures for blood sample collection because of poor tolerability or poor venous access. 19.

Primary | Baseline-adjusted Area Under Effect Curve (AUEC) for LDL-C for Evolocumab and Alirocumab | The values and variability of AUEC for LDL-C at low, intermediate-low, intermediate-high, and high doses of evolocumab and alirocumab. AUEC was calculated as the baseline-subtracted area under the LDL-C concentration-time curve expressed in units of mg/(dL*day). More negative AUEC values represent greater reductions in LDL-C exposure from baseline. The standard deviation is noted in parentheses. For each subject and dose, the maximum decrease from baseline LDL-C was determined using all sampled timepoints. AUEC values were log-transformed and an ANCOVA model was used to calculate geometric means and 90% confidence intervals for each treatment group. | Day -1 and 0h (pre-dose), 24h (post-dose); once on Day 2, 3, 4, 5, 7, 10, 14, 21, 28, 35, and 42 for all Arms.
