Pomerantz Law Firm Launches Investigation into Atara Biotherapeutics for Alleged Securities Violations

Pomerantz Law Firm Investigates Atara Biotherapeutics

On February 11, 2025, the Pomerantz Law Firm, a renowned player in corporate and securities class litigation, announced it is investigating claims on behalf of investors of Atara Biotherapeutics, Inc. (NASDAQ: ATRA). This investigation stems from concerns over possible securities fraud or other illegal business practices associated with Atara’s recent actions.

Atara faced significant turmoil when, on January 16, 2025, the company disclosed that it had received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding its Biologics License Application (BLA) for its treatment, EBVALLO™ (tabelecleucel). This treatment targeted adult and pediatric patients aged two years and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD).

The message from the company indicated that the CRL primarily pertained to findings from a routine inspection of a third-party manufacturing facility involved in producing EBVALLO. The result of this announcement led to a staggering decline in Atara's stock price, which plummeted by 50.08%, from $13.16 to $6.57 per share over the ensuing two trading days.

Further compounding the company's challenges, on January 21, 2025, Atara informed stakeholders that the FDA had imposed a clinical hold on its ongoing Investigational New Drug (IND) applications. This action was attributed to significant compliance issues in Good Manufacturing Practices (GMP) uncovered during the pre-license inspection referenced in the CRL. Following this news, the stock dropped again, closing at $6.05, a decrease of 7.91% from the previous trading day.

The Pomerantz Law Firm, which has established a solid reputation over its 80-year history for advocating for victims of corporate misconduct and securities fraud, is now urging investors affected by Atara’s recent developments to reach out for assistance. The firm has a rich history of holding companies accountable and has secured numerous multimillion-dollar settlements for those wronged by corporate actions.

As the investigation unfolds, it aims to uncover the full extent of the alleged unlawful practices that may have detrimentally affected the investors of Atara Biotherapeutics. Individuals interested in participating in the collective inquiry are encouraged to contact Danielle Peyton through the firm’s provided communication channels.

Conclusion

Atara Biotherapeutics is currently facing a serious examination into its business practices and responses to FDA notifications regarding its critical therapeutic applications.
