Pomerantz Law Firm Launches Investigation into Atara Biotherapeutics for Potential Investor Claims

Investor Alert: Pomerantz Law Firm Investigates Atara Biotherapeutics

The Pomerantz Law Firm has initiated an investigation regarding Atara Biotherapeutics, Inc. (NASDAQ: ATRA) on behalf of its investors. This legal action comes in light of significant concerns surrounding the company's recent activities that may involve securities fraud or other unlawful business practices.

Background of the Investigation

Atara Biotherapeutics specializes in developing immunotherapies for cancer patients. On January 12, 2026, the company made a shocking announcement that the U.S. Food and Drug Administration (FDA) had issued a Complete Response Letter (CRL) concerning their Biologics License Application (BLA) for EBVALLO™ (tabelecleucel). This treatment is for patients two years and older suffering from Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD).

The FDA's CRL conveyed that Atara's BLA could not be approved in its current form and cited deficiencies in their clinical trial data. Specifically, the FDA noted that the ALLELE trial design had become problematic for validating the efficacy of the treatment. This unexpected feedback resulted in a troubling fallout for investors, as Atara's stock plummeted by 56.99%, closing at $5.88 per share on January 12.

The firm is extending an invitation for affected individuals to come forward and join the potential class action.
