The Epstein-Barr virus is among the most common viruses associated diseases including multiple sclerosis and certain cancers. Atara Biotherapeutics is developing off-the-shelf, T-cell immunotherapies designed to target cancers and autoimmune conditions driven by the Epstein-Barr virus. It is also using its EBV T-cell platform to develop next-generation allogenic CAR T therapies to target a range of non-EBV associated diseases. We spoke to Pascal Touchon, president and CEO of Atara, about the role of the Epstein-Barr virus in certain cancers and autoimmune conditions, the company’s platform technology for allogenic CAR T therapies, and why it has implications beyond EBV-driven diseases.
