The data were presented at the 2018 American Society of Clinical Oncology (ASCO) annual meeting in Chicago,Illinois. During an oral presentation on June2, 2018, entitled, “Pilot Study of NY-ESO-1c259T Cells in Advanced Myxoid/Round Cell Liposarcoma,” Dr.Sandra P. D’Angelo of the Memorial Sloan Kettering Cancer Center presented an update from this ongoing study.

On June4, 2018, Company issued a press release announcing a presentation on safety data from its two ongoing pilot studies with SPEAR T-cells targeting MAGE-A10 in non-small cell lung cancer (NSCLC) and the triple tumor study in bladder, melanoma, and head& neck cancers. The data were presented during a poster session at the 2018 ASCO annual meeting.

On June4, 2018, the Company also issued a press release announcing that the independent safety review committee has recommended dose escalation in the Company’s MAGE-A4 basket study, based on an acceptable safety profile in three patients dosed with 100 million cells. The Company will start treating patients with the target dose of one billion transduced MAGE-A4 SPEAR T-cells in its ongoing basket study.

In addition, after confirming expression levels for MAGE-A4 from synovial sarcoma and myxoid/round cell liposarcoma (MRCLS) tumor samples, Adaptimmune has amended the study to add these two indications to the ongoing basket study, which already includes bladder, melanoma, head& neck, esophageal, gastric, ovarian, and non-small cell lung (NSCLC) cancers. Screening of patients with synovial sarcoma and MRCLS is ongoing.

In the same press releases, the Company also provided call in details and the webcast link for a live teleconference that it will host on June4, 2018 at 8:00 AM EDT (1:00 PM BST) to discuss the updated data. Call in details and the webcast link are also available in the Investors section of Adaptimmune’s website (https://www.adaptimmune.com).

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.
