Celyad to Present CYAD-01 Solid Tumor Clinical Updates and Pre-Clinical Pipeline Data at the 2018 SITC Annual Meeting

Celyad’s pipeline to be highlighted in oral and poster presentations at SITC 2018

MONT-SAINT-GUIBERT, Belgium, Oct. 04, 2018 (GLOBE NEWSWIRE) -- Celyad (Euronext Brussels and Paris, and NASDAQ: CYAD), a clinical-stage biopharmaceutical company focused on the development of specialized CAR-T cell-based therapies, today announced that clinical and preclinical data on the company’s pipeline of candidates will be presented at the Society for Immunotherapy of Cancer (SITC) Annual Meeting being held November 7-11, 2018, in Washington, D.C. Ten different abstracts have been selected by the SITC Program Committee attesting to a vigorous and ambitious research program.

“We view SITC 2018 as an important meeting for a number of reasons,” said David Gilham, Ph.D., VP of Research and Development at Celyad. “Firstly, we will provide a clinical update on our CYAD-01 program in solid tumors. Secondly, we will share how we’ve continued to develop the early academic NKG2D CAR-T asset into the commercially feasible clinical entity CYAD-01. We will provide an update on our next generation CAR-T pipeline, and in particular on our non-gene edited allogeneic CAR-T program. We believe we are on a trajectory to be a leading player in the autologous and allogeneic CAR-T cell therapy landscape in the years to come.”
