Only approved therapy for EU patients with a rare and life-threatening cancer with a median survival of just a few months

Represents the first worldwide approval of an allogeneic T-cell immunotherapy

Pierre Fabre will lead the marketing and distribution activities in Europe

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

The approval follows a positive opinion issued in October by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) and is applicable to the 27 Member States of the European Union plus Iceland, Norway and Liechtenstein. The positive opinion of the CHMP is based on the results of the pivotal phase 3 study, ALLELE.[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 needs,” said Pascal Touchon, President and CEO of Atara. “To be the first allogeneic or donor-derived T-cell immunotherapy to receive approval from any regulatory agency in the world represents a historic moment for Atara, our European partner, Pierre Fabre, and for the entire field of cell therapy.” .

EBV PTLD is a rare, acute, and life-threatening hematologic malignancy that occurs after transplantation when the patient’s T-cell immune response is compromised by immunosuppression. It can affect patients who have undergone a solid organ transplant (SOT) or an allogeneic hematopoietic stem cell transplant (HSCT). The median survival of EBV PTLD patients who have failed standard treatments is low, at 0.7 months and 4.1 months for HSCT and TOS, respectively, underscoring the great need for new therapeutic options.

Under a previously announced licensing agreement with Atara, Pierre Fabre will lead all marketing and distribution activities in Europe and other selected markets, in addition to medical and regulatory activities.

“Ebvallo® represents a significant moment in the field of cell therapy, and a breakthrough for European EBV PTLD patients,” said Eric Ducournau, CEO of Pierre Fabre, Atara’s European business partner. “We are proud and delighted to bring this innovative therapy to market, which will further strengthen Pierre Fabre’s portfolio in oncology, hematology and rare diseases.”

Ebvallo® has orphan drug designation in Europe. Orphan designation is reserved for medicines that treat life-threatening or chronically debilitating rare diseases that affect a small number of patients (less than five people in 10,000 in the EU). Authorized orphan drugs enjoy ten years of commercial exclusivity, which protects them from competition from similar drugs with the same therapeutic indication, which cannot be marketed during the exclusivity period.
