简要总结
This is a randomized, double-blind, multicenter, placebo-controlled, multiple-dose escalating clinical trial designed to evaluate the safety, tolerability, pharmacokinetics, and immunogenicity profile of B1344 in patients with NAFLD. Additionally, the trial will conduct preliminary observations on the efficacy of B1344, aiming to provide early proof of concept for B1344 as a therapeutic agent for NASH.
