简要总结
The goal of this clinical trial is to study the tolerability, safety, pharmacokinetics and immunogenicity of investigational drug in healthy subjects. The main questions it aims to answer are:
- Safety and tolerability of investigational drug.
- pharmacokinetics and immunogenicity of investigational drug. Participants will receive a single intravenous administration of investigational drug or placebo. Blood samples are collected at specified time points.
