Current Status and Prospects of Camrelizumab, A Humanized Antibody Against Programmed Cell Death Receptor 1.

BACKGROUND: Camrelizumab, which was launched in China on May 29, 2019, is a humanized anti-programmed cell death-1 (PD-1) antibody. It is used for the treatment of complicated or refractory classic Hodgkin's lymphoma with at least second-line chemotherapy. On March 4, 2020, camrelizumab was approved as a second-line drug in China for the treatment of advanced hepatocellular carcinoma. Currently, camrelizumab is undergoing clinical research for advanced solid tumors such as liver cancer, gastric cancer, esophageal cancer, and lung cancer, and all have shown clinical efficacy.
OBJECTIVE: This review describes preclinical studies on camrelizumab and its efficacy and safety in clinical studies in various tumors.
METHODS: A literature search was conducted on basic research and clinical trials of camrelizumab determined its pharmacology, toxicology, pharmacokinetic properties, and current clinical research status. We also analyzed the difference between camrelizumab and other PD-1 antibodies.
RESULTS: The results of preclinical studies show that camrelizumab binds to the PD-1 receptor and has stable anti-tumor activity in a dose-dependent manner. Clinical studies show that camrelizumab has therapeutic effects on a variety of tumors. The incidence of adverse reactions with camrelizumab is low, with most being mild, reversible, and predictable.
CONCLUSION: This review summarizes the current status of preclinical and clinical studies on camrelizumab. Current research confirms that camrelizumab alone or in combination with other drugs shows significant anti-cancer activity and a low incidence of adverse reactions. However, further studies are needed to verify the application potential of camrelizumab in a variety of tumors.
