"The resubmission of the tab-cel BLA was an important milestone this quarter, and we remain focused on supporting Pierre Fabre Pharmaceuticals (PFP) toward a successful outcome," said Cokey Nguyen, President and Chief Executive Officer of Atara. "We continue to believe in tab-cel’s significant commercial potential in the U.S. In parallel, we are taking steps to control expenses with the goal of protecting and maximizing shareholder value while enhancing our strategic flexibility."

Tabelecleucel (tab-cel or EBVALLO) for Post-Transplant Lymphoproliferative Disease (PTLD)

As previously communicated, the U.S. Food and Drug Administration (FDA) has accepted the Biologics License Application (BLA) resubmission for tabelecleucel, with a proposed indication as monotherapy for treatment of adult and pediatric patients two years of age and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy.

The BLA has a Class 2 Resubmission Prescription Drug User Fee Act (PDUFA) target action date of March 31, 2027.

If tabelecleucel is approved by the FDA, Atara would be eligible to receive a $31 million milestone payment pursuant to Atara’s commercialization agreement with Pierre Fabre Laboratories. Atara would also be eligible to receive significant double-digit tiered royalties as a percentage of net sales, as well as milestones related to commercial sales of EBVALLO.

Total revenues were $1.2 million for the third quarter 2026, as compared to $3.5 million for the same period in 2025. Total revenues decreased by $2.3 million year-over-year, primarily due to the one-time sale of clinical inventory in the prior year.

2026 Outlook and Cash Runway:

Operating expenses are expected to decline significantly year-over-year, reflecting the full-year benefit of cost-reduction initiatives implemented in 2025 and the first half of 2026.
Atara expects its cash, cash equivalents, and short-term investments as of September 30, 2026, combined with operating efficiencies achieved in 2025 and the first half of 2026, will be sufficient to fund planned operations into mid-2027.
