Investing.com -- Atara Biotherapeutics Inc (NASDAQ:ATRA) stock surged 7% after the U.S. Food and Drug Administration (FDA) accepted the filing of its Biologics License Application (BLA) for tabelecleucel (tab-cel).

The BLA is for tab-cel as a monotherapy for adult and pediatric patients two years and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy. Currently, there are no FDA-approved therapies for this indication.

The FDA granted Priority Review to the application with a Prescription Drug User Fee Act (PDUFA) target action date of January 10, 2026. The BLA was classified as a Class 2 Resubmission.

"The acceptance of the tab-cel resubmission moves us one step closer towards making this first-of-its-kind treatment available to patients in the U.S.," said Cokey Nguyen, President and Chief Executive Officer of Atara.

Tab-cel is an allogeneic, EBV-specific T-cell immunotherapy designed to target and eliminate EBV-infected cells. The application is supported by data from more than 430 patients treated with tab-cel across multiple diseases, including the pivotal ALLELE study which demonstrated a statistically significant 48.8% Objective Response Rate.

The therapy has previously received Breakthrough Therapy Designation from the FDA for the treatment of rituximab-refractory EBV-associated lymphoproliferative disease and has orphan drug designation for EBV-positive post-transplant lymphoproliferative disorders.

Atara is working with Pierre Fabre Pharmaceuticals to prepare for the potential U.S. launch of the therapy.
