Atara Biotherapeutics, Inc. is a clinical-stage biopharmaceutical company headquartered in South San Francisco that specializes in the development of allogeneic T-cell immunotherapies. The company’s pipeline leverages healthy donor–derived T cells that are selected, expanded, and banked to create off-the-shelf products designed to target viral antigens implicated in a range of cancers and immune-mediated disorders. By relying on premanufactured cell therapies, Atara aims to overcome many of the logistical challenges associated with autologous approaches, including extended manufacturing timelines and patient-to-patient variability.
Atara’s lead investigational therapy, tabelecleucel (formerly ATA129), is in advanced clinical trials for the treatment of Epstein–Barr virus (EBV) positive lymphomas and post-transplant lymphoproliferative disease (PTLD). The company’s broader pipeline includes ATA188, a donor-derived T-cell candidate targeting EBV proteins implicated in multiple sclerosis, and ATA3271, an innate-like CAR T-cell therapy directed at CD19 for B-cell malignancies. These programs reflect Atara’s strategy to extend its off-the-shelf platform across oncology, autoimmune disease, and other viral-associated conditions.
Since its founding in 2012, Atara has expanded its global footprint with research, development, and manufacturing operations in the United States and Europe. Through collaborations with academic institutions and strategic partnerships within the pharmaceutical industry, the company continues to refine its proprietary T-cell expansion and enrichment technologies. This infrastructure supports scalable production and aims to standardize product quality, batch after batch, to ensure broad patient access.
Atara’s leadership team, led by Chief Executive Officer Pascal Touchon, brings extensive experience in immunology, cell therapy, and late-stage product development. Under this guidance, Atara has achieved multiple clinical milestones and engaged regulatory authorities across key geographies. Looking ahead, the company remains focused on advancing its clinical programs and validating the potential of its allogeneic T-cell platform to address critical unmet needs in oncology and immune-mediated diseases.
