Brief summary

Study to assess the LDL-C lowering efficacy of different doses of LIB003 administered every 4 weeks in subjects on stable statin and/or ezetimibe therapy

Detailed description

Randomized, Double-Blind, Placebo-Controlled, Phase 2 study to assess the LDL-C lowering efficacy at Week 12 of various doses of LIB003 administered subcutaneously (SC) every 4 weeks (Q4W) in patients with hypercholesterolemia on stable diet and oral LDL-C-lowering drug therapy.
