About ADAPTIMMUNE THERAPEUTICS PLC (NASDAQ:ADAP)

Adaptimmune Therapeutics plc is a clinical-stage biopharmaceutical company. The Company is focused on cancer immunotherapy products based on its T-cell receptor (TCR) platform. The Company has developed a platform that enables it to identify cancer targets in the form of peptides, which are short sequences of amino acids, find and genetically engineer TCRs, and produce TCR therapeutic candidates for administration to patients. The Company engineers TCRs to increase their affinity to cancer-specific peptides, including its lead target peptides, NY-ESO-1 and MAGE-A10, in order to target and then destroy cancer cells in patients. The Company’s TCR therapeutic candidates are able to target intracellular, as well as extracellular cancer antigens. The TCRs consist of approximately two associated protein chains: the alpha and beta chains. Each of the chains has approximately two regions: a variable region and a constant region.
