A Study of Clazakizumab (LY5724886) in Adults With Elevated hsCRP and at Increased Risk for Cardiovascular Event (CLARITY-CRP)

August 21, 2026 updated by: Eli Lilly and Company

A Phase 2b, Randomized, Double-Blind, Placebo-Controlled Study to Investigate the Efficacy and Safety of Clazakizumab in Reducing hsCRP in Adults With Elevated hsCRP and Established ASCVD or at Increased Risk for ASCVD Events

The purpose of this study is to measure the change in high-sensitivity C-reactive protein (hsCRP), a marker of inflammation in the body, with clazakizumab compared with placebo in adults who have elevated hsCRP and at increased risk for cardiovascular event.

Participation in the study will last about 9 months.
