简要总结
This is a Phase II, multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy and safety of SAL003, a recombinant fully human anti-PCSK9 monoclonal antibody, in combination with a stable dose of atorvastatin in patients with hypercholesterolemia and mixed dyslipidemia.
详细描述
This is a Phase II, multicenter, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy, safety, and pharmacokinetics of SAL003, a recombinant fully human anti-PCSK9 monoclonal antibody, when used in combination with stable, background atorvastatin therapy in adult patients with hypercholesterolemia and mixed dyslipidemia.
The study is structured into four distinct periods to ensure patient eligibility, standardize background therapy, and assess both short-term and longer-term effects of the investigational product.
