Shareholders Encouraged to Join Class Action Against aTyr Pharma, Inc. Amid Significant Stock Drop

Shareholders Advised to Participate in aTyr Pharma Class Action

In a recent notice issued by The Gross Law Firm, shareholders of aTyr Pharma, Inc. (NASDAQ: ATYR) are being urged to consider joining a class action lawsuit. This development comes in the wake of substantial stock losses affecting many investors, particularly those who purchased shares during a defined class period. The law firm emphasizes that those affected can still participate in recovery efforts, even if they do not seek lead plaintiff status.

Background of the Case

According to the notice from The Gross Law Firm, shareholders who acquired stock in aTyr between November 7, 2024, and September 12, 2025, are potentially eligible to join this class action. The core allegations stem from claims that aTyr’s management provided overly optimistic statements regarding the efficacy of their drug, Efzofitimod. Specifically, it has been asserted that these declarations hid crucial facts and misled investors about the drug’s ability to reduce steroid dependency completely.

The situation took a downward turn on September 15, 2025, when aTyr held an investor call announcing disappointing results from the EFZO-FIT clinical study. The company revealed that it failed to meet its primary endpoint—concerning the change from baseline in mean daily oral steroid consumption after 48 weeks of treatment. Following the announcement, the company's stock plummeted dramatically, falling from $6.03 per share to $1.02 per share, which represents a staggering 83.2% loss in just one day.

Importance of Action

As the announcement noted, shareholders affected by this decline are encouraged to take action. The deadline for registering in this class action case is December 8, 2025, meaning investors must act quickly to ensure their participation.
