NEW YORK, Dec. 03, 2025 (GLOBE NEWSWIRE) -- Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against aTyr Pharma, Inc. (“aTyr” or the “Company”) (NASDAQ: ATYR) and reminds investors of the December 8, 2025 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.
Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.
As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: Defendants provided overwhelmingly positive statements to investors while, at the same time, disseminating false and misleading statements and/or concealing material adverse facts concerning the efficacy of Efzofitimod, particularly, the drug’s capability to allow a patient to completely taper their steroid usage. This caused Plaintiff and other shareholders to purchase aTyr’s securities at artificially inflated prices.
In the EFZO-FIT study, efzofitimod failed to show any change in mean daily oral corticosteroid (OCS) dose at week 48, with the OCS dose reducing by an average of 2.79mg for 5.0 mg/kg efzofitimod compared to 3.52 mg for placebo. Complete steroid withdrawal was achieved for 52.6% of patients treated with 5.0 mg/kg efzofitimod versus 40.2% on placebo.
After aTyr Pharma released the results, its stock dropped by 83.25%, from a September 12th market close of $6.03 to a September 15th market close of $1.01.
The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.
Faruqi & Faruqi, LLP also encourages anyone with information regarding aTyr’s conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
