简要总结
This is a multicenter, randomized, double-blind, placebo-controlled, two-stage phase II clinical study. The main objective is to evaluate the efficacy and safety of HSK21542 injection and explore the recommended dose and administration frequency for subsequent Phase II studies in conjunction with the pharmacodynamic (PD) and pharmacokinetic (PK) characteristics.
