Atara Biotherapeutics Announces First Quarter Financial Results and Operational Progress
Atara has transferred all manufacturing responsibility to Pierre Fabre Laboratories, including all costs associated with the manufacturing
and supply of tabelecleucel for development and commercialization worldwide
Atara expects to reduce its operating expenses
year-over-year by approximately 65% in 2025 as a result of implemented cost reduction initiatives
Atara has entered into an
underwriting agreement for an offering with expected gross proceeds of $16 million that Atara believes is sufficient to fund the ongoing activities required to achieve potential BLA approval
THOUSAND OAKS, Calif. May 15, 2025 Atara Biotherapeutics, Inc. (Nasdaq: ATRA), a leader in T-cell
immunotherapy, leveraging its novel allogeneic Epstein-Barr virus (EBV) T-cell platform to develop transformative therapies for patients with cancer and autoimmune diseases, today reported financial results
for the first quarter 2025 and business updates.
We are pleased that we have secured additional financing that is expected to extend our cash
runway through the first quarter of 2026 said Cokey Nguyen Ph.D., President and Chief Executive Officer of Atara. This enables Atara to continue to work to reduce costs and liabilities while maintaining the required support to achieve
potential BLA approval.
Tabelecleucel (tab-cel or EbvalloTM) for Post-Transplant Lymphoproliferative Disease (PTLD)
Programs Discontinued
Strategic Option Evaluation: As communicated in January and March, Atara engaged a well-known financial advisor to support the assessment of a range of
strategic options, which may include, but are not limited to, an acquisition, merger, reverse merger, other business combinations, sale of assets, or other strategic transactions. In April 2025, Atara paused its review of strategic options, pending
the Type A meeting with the FDA which is scheduled in the second quarter of 2025, to discuss the plan to address the issues raised by the FDA in the CRL and the path forward for resubmission of the EBVALLOTM BLA.
Organizational Restructuring: In May 2025, Atara implemented a strategic restructuring to
further reduce operating expenses and due to the winddown of the CAR T programs. This restructuring resulted in a company-wide workforce reduction of approximately 30%, retaining approximately 23 personnel essential to execute on its remaining
transition responsibilities under the EBVALLOTM collaboration with Pierre Fabre Laboratories, including as the BLA holder until approval.
Financial Update: Atara has entered into an underwriting agreement for the issuance and sale of 834,237 shares of its common stock at a purchase price
of $6.61 per share and the issuance and sale of pre-funded warrants to purchase up to 1,587,108 shares of its common stock at a purchase price of $6.6099 per share, representing fair market value based on
closing, to entities affiliated with Adiumentum Capital Management, EcoR1 Capital, Panacea Venture and Redmile Group. The proceeds to Atara from the offering are expected to be $16 million, before deducting underwriting discounts and
commissions and estimated offering expenses payable by Atara. Atara currently intends to use the net proceeds from the offering to fund its ongoing activities required to achieve biologics license application (BLA) approval for tab-cel, and for
working capital and general corporate purposes. The offering is expected to close on May 16, 2025, subject to the satisfaction of customary closing conditions.
