Efficacy And Safety Of Bococizumab For Lipid Lowering In Asian Hypercholesterolemia Subjects

Phase 3

Withdrawn

• Conditions: Primary Hyperlipidemia or Mixed Dyslipidemia
• Interventions: Biological: Bococizumab; Drug: Placebo

• Registration Number: NCT02947334
• Lead Sponsor: Pfizer

Brief Summary

This study is a Phase 3, double blind, placebo controlled, randomized, stratified, parallel group, multi-center clinical trial designed to compare the efficacy and safety of bococizumab 150 mg SC Q2wks to placebo for LDL-C lowering in subjects with primary hyperlipidemia or mixed dyslipidemia at high or very high risk for CV events. The study will enroll a total of approximately 750 subjects from 4 - 5 Asian countries/areas (including China mainland); of which approximately 600 subjects will be from sites in China. Subjects will be randomized into a bococizumab treatment arm and a placebo arm in a 1:1 ratio.

Detailed Description

After providing consent, subjects will enter a screening period of approximately 28 days to verify eligibility for the trial. Eligible subjects will be considered enrolled and progress to the Randomization visit. Results from screening evaluations will be reviewed and only subjects who continue to meet all eligibility criteria will be randomized. Randomized subjects will enter the 12-week treatment period, followed by a 40-week long-term treatment period and a 6 week follow-up, for a total of 58 weeks (approximately 14 months) study participation. Subjects will attend clinic visits as shown in the Schedule of Activities. Subjects will be randomized to receive either 150 mg Q2wks of bococizumab or placebo in a 1:1 ratio. Lipid levels will be blinded to the investigator and staff, subject and sponsor.
