About

The study consists of 2 parts:

Part I study: to preliminarily compare the PK profile of HLX12 and Cyramza This study is an open-label, randomized, parallel-controlled, intravenous single-dose pretrial study comparing the pharmacokinetic profile, safety, tolerability and immunogenicity of HLX12 and Ramucirumab in healthy male adult subjects. The number of subjects is set to 24, who will be randomized into two groups, and each group has the same number of subjects (n=12). Group 1 will receive intravenous infusion of the test preparation T HLX12, while Group 2 will receive Cyramza, once in both groups.

Part II study: to compare the PK similarity between HLX12 and Cyramza This study is a randomized, double-blind, parallel-controlled, intravenous single-dose Phase I clinical study comparing the pharmacokinetic profile, safety, tolerability and immunogenicity of HLX12 and Ramucirumab in healthy male adult subjects.The number of subjects is set to 128, and the treatment is the same with Part I study.
