Only Approved Therapy for EU Patients with Rare and Potentially Deadly Cancer Facing Median Survival of Only a Few Months

Represents First Approval of an Allogeneic T-Cell Immunotherapy Globally

Pierre Fabre to Lead Commercialization and Distribution Activities in Europe

THOUSAND OAKS, CA, USA and CASTRES, France I December 19, 2022 I Atara Biotherapeutics, Inc. (Nasdaq: ATRA), and Pierre Fabre today announced that the European Commission (EC) has granted marketing authorization for Ebvallo® (tabelecleucel) as a monotherapy for treatment of adult and pediatric patients two years of age and older with relapsed or refractory Epstein–Barr virus positive post–transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy. For solid organ transplant patients, prior therapy includes chemotherapy unless chemotherapy is inappropriate.

The approval follows a positive opinion in October by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) and is applicable to all 27 European Union member states plus Iceland, Norway and Liechtenstein. The CHMP positive opinion is based on results from the pivotal Phase 3 ALLELE study.[1] In this study, Ebvallo® demonstrated a favorable risk-benefit profile.

“The approval of Ebvallo® in Europe represents a medical breakthrough for patients with significant unmet need,” said Pascal Touchon, President and Chief Executive Officer of Atara. “As the first allogeneic, or donor-derived, T-cell immunotherapy to receive approval from any regulatory agency in the world, this represents a historic moment for Atara, our European partner, Pierre Fabre, and for the broader cell therapy field.”

EBV+ PTLD is a rare, acute, and potentially deadly hematologic malignancy that occurs after transplantation when a patient’s T-cell immune response is compromised by immunosuppression. It can impact patients who have undergone solid organ transplant (SOT) or allogeneic hematopoietic stem cell transplant (HCT). Poor median survival of 0.7 months and 4.1 months for HCT and SOT, respectively, is reported in EBV+ PTLD patients for whom standard of care failed, underscoring the significant need for new therapeutic options.

Under a previously announced License Agreement with Atara, Pierre Fabre will lead all commercialization and distribution activities in Europe and select other markets, in addition to medical and regulatory activities following the transfer of the MAA from Atara to Pierre Fabre.

“Ebvallo® represents a significant moment in the cell therapy space, and a breakthrough for European patients with EBV+ PTLD,” said Eric Ducournau, CEO of Pierre Fabre, Atara’s commercialization partner in Europe. “We are proud and excited to bring this innovative therapy to the marketplace, which will reinforce Pierre Fabre’s portfolio in oncology, hematology, and rare diseases.”

Ebvallo® has orphan designation in Europe. Orphan designation is reserved for medicines treating life-threatening or chronically debilitating diseases that are rare (affecting not more than five in 10,000 people in the EU). Authorized orphan medicines benefit from ten years of market exclusivity, protecting them from competition with similar medicines with the same therapeutic indication, which cannot be marketed during the exclusivity period.

Atara Biotherapeutics, Inc. (@Atarabio) is a pioneer in T-cell immunotherapy leveraging its novel allogeneic EBV T-cell platform to develop transformative therapies for patients with serious diseases including solid tumors, hematologic cancers and autoimmune disease. With our lead program receiving marketing authorization in Europe, Atara is the most advanced allogeneic T-cell immunotherapy company and intends to rapidly deliver off-the-shelf treatments to patients with high unmet medical need. Our platform leverages the unique biology of EBV T cells and has the capability to treat a wide range of EBV-associated diseases, or other serious diseases through incorporation of engineered CARs (chimeric antigen receptors) or TCRs (T-cell receptors). Atara is applying this one platform, which does not require TCR or HLA gene editing, to create a robust pipeline including: tab-cel in Phase 3 development for Epstein-Barr virus-driven post-transplant lymphoproliferative disease (EBV+ PTLD) and other EBV-driven diseases; ATA188, a T-cell immunotherapy targeting EBV antigens as a potential treatment for multiple sclerosis; and multiple next-generation chimeric antigen receptor T-cell (CAR-T) immunotherapies for both solid tumors and hematologic malignancies. Improving patients’ lives is our mission and we will never stop working to bring transformative therapies to those in need. Atara is headquartered in Southern California.
