Adaptimmune Announces Responses in Second Solid Tumor Indication with NY-ESO SPEAR T-cellsPHILADELPHIA and OXFORD, U.K., March 15, 2018 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq:ADAP), a leader in T-cell therapy to treat cancer, today reported three partial responses (two confirmed and one to be confirmed), and one stable disease in the first four patients dosed with NY-ESO SPEAR T-cells in a second solid tumor: myxoid/ round cell liposarcoma (MRCLS). Patients tolerated treatment well with cytokine release syndrome (CRS) managed following standard treatment guidelines. GlaxoSmithKline plc (LSE:GSK) (NYSE:GSK) exercised its option to exclusively license the right to research, develop, and commercialize NY-ESO SPEAR T-cell therapy program in September 2017. Transition of this program to GSK is ongoing. “We are encouraged by the initial responses seen in the first patients with MRCLS treated with NY-ESO SPEAR T-cells, as it validates the potential of our platform to treat a broad range of tumors, including those that are known to be unresponsive to current immunotherapies,” said Rafael Amado, Adaptimmune’s Chief Medical Officer. “Although MRCLS is a soft tissue sarcoma which commonly expresses NY-ESO, there are fundamental differences in its clinical course, natural history, molecular signature, and responsiveness to standard treatments that make it distinct from synovial sarcoma. As we expect data from our other trials with our wholly owned assets throughout 2018, these results in a second solid tumor strengthen our conviction that our pipeline of unique TCRs will be capable of addressing multiple solid tumors.” More about Soft Tissue Sarcomas: It is estimated that there are approximately 2000 patients in the United States ad Europe with MRCLS each year. MRCLS has a peak incidence of occurrence in patients who are 30 to 50 years of age and it typically follows a more aggressive course than other liposarcomas. MRCLS also exhibits a unique metastatic pattern arising first in the proximal areas of the extremities and typically spreading to the bones (particularly the spine), serosal surfaces, retroperitoneum, abdomen, pelvis, as well as to other soft tissues. This metastatic pattern is different from the characteristic pulmonary spread exhibited by synovial sarcoma.
