Faruqi & Faruqi Investigates Investor Claims in aTyr Pharma Securities

Faruqi & Faruqi Investigates Claims Against aTyr Pharma

Faruqi & Faruqi, LLP, a prominent national securities law firm, is currently probing allegations concerning aTyr Pharma, Inc. (NASDAQ: ATYR) on behalf of investors. This investigation follows significant losses suffered by shareholders who acquired aTyr securities between January 16, 2025, and September 12, 2025. The firm encourages these investors to reach out for guidance on their legal options.

Overview of the Allegations

According to the firm, the complaints suggest that aTyr Pharma, along with its executives, may have violated federal securities laws by disseminating misleading statements and failing to disclose crucial information about their drug, Efzofitimod. Investors were reportedly misled by overwhelmingly positive communications while adverse facts about the drug’s efficacy were concealed.

The problem arose when the results of the EFZO-FIT study revealed that Efzofitimod did not significantly reduce the mean daily oral corticosteroid dose compared to a placebo. Specifically, the average reduction was 2.79 mg for the treatment group versus 3.52 mg for placebo recipients. Moreover, while 52.6% of patients using Efzofitimod achieved complete steroid withdrawal, this figure was outpaced by the 40.2% who achieved the same result on placebo.

The Impact on Shareholder Value

Following the release of these adverse findings, aTyr's stock price plummeted by over 83%, dropping from a closing price of $6.03 on September 12, 2025, to just $1.01 by September 15, 2025. This dramatic decline in share value signals the potential financial devastation faced by investors who acted on the misleading information previously provided by the company.

Legal Considerations

Faruqi & Faruqi is reminding investors that the deadline to apply for the role of lead plaintiff in a federal class action lawsuit against aTyr Pharma is December 9, 2025. The lead plaintiff is typically the individual who has the largest financial stake in the claims made against the company and is representative of the interests of all class members. Any member of the class can either seek to become a lead plaintiff or choose to remain an absent participant. It’s important to note that a decision to not become a lead plaintiff does not affect the ability to reclaim losses in any legal recovery.

Encouraging Communication

The firm is actively seeking any additional information from stakeholders, including whistleblowers, former employees, and other investors regarding aTyr's practices and its effects on shareholder value. Individuals who may have pertinent details are encouraged to reach out to the firm directly.

Josh Wilson, a partner at Faruqi & Faruqi, is spearheading this investigation and has opened lines of communication for affected individuals to discuss their situations further. Investors can call Wilson at 877-247-4292 or 212-983-9330 (Ext. 1310) for more information.

Conclusion

This situation represents another significant example of how misleading corporate information can have serious ramifications for investors.
