NCT01953328
First received: September 26, 2013
Last updated: February 28, 2014
Last verified: February 2014
  Purpose

The primary hypothesis is that both dosing regimens of evolocumab (AMG 145) SC will be well tolerated and will result in greater reduction of LDL-C, compared with placebo, when used in combination with statin therapy in subjects with high cardiovascular risk and with hyperlipidemia or mixed dyslipidemia.


Condition Intervention Phase

Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate Safety, Tolerability and Efficacy of Evolocumab (AMG145) on LDL-C in Combination With Statin Therapy in Japanese Subjects With High Cardiovascular Risk and With Hyperlipidemia or Mixed Dyslipidemia
