A Robust Pipeline

Multiple T-Cell Immunotherapy Product Candidates in Clinical Development

Atara Biotherapeutics’s robust, late-stage pipeline features a host of potentially transformative T-cell immunotherapies for cancer, autoimmune and viral diseases. Tab-cel® (tabelecleucel) is in Phase 3 development for patients with Epstein-Barr virus-associated post-transplant lymphoproliferative disease (EBV+ PTLD) as well as in earlier stage development for other EBV-associated diseases.
