NCT06568471

Brief Summary

This randomized study is to assess LDL-C reductions at Week 12 with monthly (Q4W \[≤31 days\]) dosing of HST101 (lerodalcibep) 300 mg administered subcutaneously (SC) compared to placebo in patients with atherosclerotic cardiovascular disease (ASCVD) or very-high/high risk for ASCVD including Heterozygous familial hypercholesterolemia (HeFH) on a stable diet and oral LDL-C lowering drug therapy, followed by 36-week open-label treatment with subsequent 4-week follow-up for total 52-week long-term safety and efficacy evaluation.
