Clinical Trial Summary

This is a single center, randomized, blind, parallel controlled clinical trial. The primary objective is to evaluate the single dose pharmacokinetics of recombinant Humanized anti-HER-2 monoclonal antibody injection GB221 in comparison with Herceptin ® in Chinese healthy adult volunteers. The main aim is to study the pharmacokinetic similarity between GB221 and Herceptin ®.

Description:

Subjects will enroll in random order, and be divided into two groups, then receive a single dose (6 mg/kg) of GB221 or Herceptin ®, and accept observation for 42 days. Throughout the course, safety data will be collected.
