TGF-β1 x LRRC32

The purpose of this study is to investigate the safety, PK, and immunogenicity of a single intravenous administration of HLX6018 in healthy subjects, based on the preliminary efficacy and safety established through in vitro and in vivo experiments.
This is a randomized, double-blind, placebo-controlled study with single dose escalation design to assess the safety, PK, and immunogenicity of HLX6018 in healthy subjects. It is planned to enroll 8-10 subjects in each of seven dose groups (0.25 mg/kg, 1.0 mg/kg, 4.0 mg/kg, 12 mg/kg, 25 mg/kg, 50 mg/kg, and 70 mg/kg). This is the first-in-human study of the investigational product.

主要研究目的：评估不同剂量HLX6018在健康受试者中的安全性和耐受性。 次要研究目的：评估HLX6018在健康受试者中的PK特征；评估HLX6018在健康受试者中的免疫原性。
