Its platform uses T cells derived from healthy donors and engineered or selected to recognize disease-associated targets, with the goal of creating “off-the-shelf” treatments that can be administered without collecting and manufacturing a patient’s own cells. The company’s leading product is tabelecleucel, marketed as Ebvallo, an allogeneic T-cell therapy designed to target Epstein-Barr virus-positive cells. Ebvallo has been approved in the United States and European Union for certain patients with relapsed or refractory Epstein-Barr virus-positive post-transplant lymphoproliferative disease, a rare and potentially life-threatening complication that can occur after organ or stem-cell transplantation. Atara has also investigated its platform in multiple sclerosis and other immune-mediated diseases, as well as additional oncology indications. Founded in 2012, Atara has operated internationally through clinical development, regulatory and commercial activities in North America and Europe. The company has collaborated with external partners to support the development, manufacturing and commercialization of its therapies. Pascal Touchon has served as Atara’s president and chief executive officer, although leadership and corporate arrangements may change as the company’s business develops.AI Generated.
