Background:

Camrelizumab (SHR-1210) is a potent humanied high-affinity IgG4-κ monoclonal antibody (mAb) to PD-1. Camrelizumab binds PD-1 at a high affinity of 3 nM and inhibits the binding interaction of PD-1 and PD-L1 with an IC50 of 0.70 nM. Camrelizumab acts as anti-PD-1/PD-L1 agent and can be used for cancer research, including NSCLC, ESCC, Hodgkin lymphoma, and advanced HCC et,al[1][2].

In a T cell proliferation assay using tuberculin treated peripheral blood mononuclear cells, Camrelizumab induces a T cell proliferation at an EC50 of 0.11 nM. In a similar assay measuring IFN-gamma secretion, Camrelizumab induces IFN-gamma production at an EC50 of 0.38 nM[2].

Camrelizumab (3 mg/kg) combines with apatinib (200 and 100 mg/kg) inhibits the tumor inhibition rates reached 63.1% and 87.3%, respectively in human PD-1 transgenic mice[1].
