PHILADELPHIA and OXFORDSHIRE, United Kingdom, Nov. 05, 2020 (GLOBE NEWSWIRE) -- Adaptimmune Therapeutics plc (Nasdaq: ADAP), a leader in cell therapy to treat cancer, today reported financial results and provided a business update for the third quarter ended September 30, 2020.

Later this month, we will present data at SITC and CTOS. Data to be presented at SITC from the dose escalation cohorts of our SURPASS trial confirm that ADP-A2M4CD8 is a highly active agent across a range of tumors. At CTOS, we will present data regarding the durability of responses in synovial sarcoma, which support our ambition to market ADPA2M4 in 2022. And finally, at our Investor Day, I will lay out our broader strategy including the opportunity we see for our late-stage pipeline, said Adrian Rawcliffe, Adaptimmunes Chief Executive Officer. Recruitment into our clinical trials has been steadily recovering following the first wave of COVID-19 and projected patient numbers currently look good for the remainder of this year and into 2021.
