The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of Atara Biotherapeutics, Inc. (“Atara” or “the Company”) (NASDAQ: ATRA) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. Atara issued a press release on July 12, 2022, updating the market on its preliminary analysis phase 2 EMBOLD study for product candidate ATA188. The Company stated, "Based on the analysis of the EMBOLD data available at the time of the IA [interim analysis], there was not a sufficient dataset to draw conclusions about the predictive value of six months EDSS improvement for 12 months EDSS improvement. The IDSMC [Independent Data and Safety Monitoring Committee] believes the six-month interim endpoint may be an inaccurate measure of the potential of this intervention in this condition." Based on this news, shares of Atara fell sharply.
