NIvolumab COmbination With Standard First-line Chemotherapy and Radiotherapy in Locally Advanced Stage IIIA/B Non-Small Cell Lung Carcinoma

Nivolumab is a fully human monoclonal antibody that targets the programmed death-1 (PD-1) cell surface membrane receptor. PD-1 is a negative regulatory molecule expressed by activated T and B lymphocytes.Binding of PD-1 to its ligands, 1 (PD-L1) and 2 (PD-L2), results in the down-regulation of lymphocyte activation. Nivolumab inhibits the interaction of programmed cell death Protein 1 (PD-1)with its ligands, PD-L1 and PD-L2, resulting in enhanced T-cell proliferation.
