Clinical Study to Compare the Pharmacokinetics and Safety of Ramucirumab Injection With Cyramza ® in Healthy Male Volunteers

Ramucirumab injection biosimilar products manufactured by Chia Tai Tianqing Pharmaceutical,

Ramucirumab Injection is a humanized monoclonal antibody based on the human immunoglobulin G1(IgG1) skeleton sequence, developed by Eli Lilly Co., the bran name is Cyramza. Ramucirumab is a vascular endothelial growth factor receptor 2 (VEGFR2) antagonist that specifically binds to VEGF receptor 2 and blocks VEGFR ligand, VEGF-A, VEGF-C, and VEGF-D binding to the receptor. As a result, Ramucirumab inhibits ligand-stimulated VEGF receptor 2 activation, thereby inhibiting ligand-induced proliferation, and human endothelial cell migration. Ramucirumab inhibits angiogenesis, thereby blocking the tumor's blood vessel supply.
