Phase Ⅰ Study to Evaluate the Safety and Tolerability of Using F520

• Status: Recruiting
• Trial end date: 2022-10-08
• Target enrollment: 0
• Participant gender: All

Summary

Recombinant Programmed death-1(PD-1) humanized monoclonal antibody injection (company code:

F520) is joint developed by Shandong New Time Pharmaceutical Co., LTD., it is the reorganization of deoxyribonucleic acid (DNA) technology in the Chinese hamster ovary (CHO) cells express system expressed in a immunoglobulin G1 (IgG1) kappa type single resistance to predominate. F520 had the different new amino acid sequence and molecular structure compared with two marketed PD-1 monoclonal antibody injection and got the approval of China Food and Drug Administration (CFDA) for clinical trial.Pharmaceutical research indicated F520 cell strain had security source, production process is stable, quality can control, preparation stability, has good compatibility with packaging materials, it has the condition of industrialization, can prepare investigational medicinal product with safety, effective, and controlled quality for clinical research.Pharmacodynamics study show the targets and mechanisms of F520is clear, tumor suppression effect is obvious.Toxicology studies show this product in high doses with low toxic, and the toxic is reversible, the most common toxicity is specific to the drug action mechanism.
