ABSTRACT: The aim of the studies was to evaluate the safety, tolerability, and efficacy of tafolecimab, a novel proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibody, in Chinese healthy volunteers and patients with hypercholesterolemia. Fifty-eight healthy volunteers (phase 1a) were randomized to receive a single dose of 25, 75, 150, 300, 450, or 600 mg tafolecimab subcutaneously, 75 or 450 mg intravenously, or placebo.
