Efficacy and Safety of JS002 as Monotherapy in Patients With Primary Hypercholesterolaemia and Mixed Dyslipidemia
Study Details
Study Description
Brief Summary
JS002 is a recombinant humanized anti-PCSK9 monoclonal antibody. This is a randomized, double-blind, placebo-controlled study to evaluate the efficacy, safety, PK/PD profile, immunogenicity as well as complete delivery of auto-injector by patients of JS002 as monotherapy in patients with primary hypercholesterolaemia and mixed dyslipidemia.
In this study, two dose cohorts(150 mg, 450 mg) are set up, and 582 subjects are planned to be enrolled (randomizedly assigned to JS002 or placebo 150/450 mg group in a 2:1:2:1 ratio).A screening period (≤6 weeks), a double-blind treatment period (12 weeks), an open-label treatment period (40 weeks), and a follow-up period (8 weeks) will be required.
