Registration Number
NCT05485961
Lead Sponsor

Brief Summary

This is a 2-part (phase 2b/3) prospective, interventional, multicenter, randomized, double-blind, placebo-controlled study. Part 1 (phase 2b) is a dose-finding study for CSL300 vs placebo. Part 2 (phase 3) aims to assess the efficacy of CSL300 on cardiovascular (CV) outcomes and safety in subjects with systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes with end stage kidney disease (ESKD) undergoing maintenance dialysis.
