In this study, a multicenter, randomized, double-blind, placebo-controlled trial design is used to evaluate the efficacy and safety of two doses of 9MW1411 injection in patients with ABSSSI caused by S. aureus.~The Recommended Phase 2 Dose (RP2D) of 9MW1411 injection for this placebo-controlled study is comprehensively selected based on the results of Phase I clinical trials and preclinical PK/PD analysis. Approximately 90 subjects with ABSSSI caused by S. aureus are planned to be enrolled, and the infection type and presence or absence of single S. aureus infection will be used as randomization stratification factors for all randomized subjects. They are randomized in a 1: 1: 1 ratio.
