Hence PD-L1 inhibitors are considered to be the most promising drug category for many different cancers. [5] [11] Not all patients respond to PD-1/PD-L1 inhibitors. The FDA has approved several assays to measure the level of PD-L1 expressed by tumor cells, in order to predict the likelihood of response to an inhibitor.
It was approved in 2014. Nivolumab is approved to treat melanoma, lung cancer, kidney cancer, bladder cancer, head and neck cancer, and Hodgkin's lymphoma.

Programmed cell death protein 1 (PD-1), (CD279 cluster of differentiation 279). PD-1 is a protein encoded in humans by the PDCD1 gene. [5] [6] PD-1 is a cell surface receptor on T cells and B cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity.
Early trial data shows that a combination of Mirati Therapeutics experimental drug adagrasib and Merck & Co's immunotherapy Keytruda helped about half of previously untreated metastatic lung ...
Cancer Therapy by Inhibition of Negative Immune Regulation (CTLA4, PD1) A2AR & A2BR: The Adenosine A2A receptor is regarded as an important checkpoint in cancer therapy because adenosine in the immune microenvironment, leading to the activation of the A2a receptor, is negative immune feedback loop and the tumor microenvironment has relatively high concentrations of adenosine. [27]
The US Food and Drug Administration (FDA) approved durvalumab for certain types of bladder, lung, and biliary tract cancer: [6] [13] [14]. Adults with locally advanced or metastatic urothelial carcinoma who either have disease progression during or following platinum-containing chemotherapy or have disease progression within twelve months of neoadjuvant or adjuvant treatment with platinum ...
