A First-in-human Study of a Novel Recombinant Humanized Anti-interleukin-6 Receptor Monoclonal Antibody

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.
