Clinical Trial Summary

This is a single center, double-blinded, placebo-controlled phase I clinical trail in healthy volunteer of meplazumab for injection. The primary objective of this phase I trial is to evaluate the safety, tolerability, pharmacokinetic characteristics and occupancy characteristics of peripheral blood cell receptors of meplazumab in healthy volunteer, and provide a reference for the dosage of meplazumab in phase II clinical trial.
