aTyr Pharma Faces Class Action: Investors Allege Misleading Statements
Did aTyr Pharma mislead its investors? Recent developments suggest this may be the case, as the company is now facing a class action lawsuit. This legal challenge stems from allegations that aTyr Pharma made misleading statements about the efficacy of its drug, Efzofitimod, leading to significant financial losses for investors. In fact, on September 15, 2025, aTyr Pharma’s stock plummeted by a staggering 83.2%, sending shockwaves through the investment community.
Understanding the Allegations Against aTyr Pharma
Several law firms have announced investigations and class action lawsuits against aTyr Pharma, including Hagens Berman, The DJS Law Group, The Gross Law Firm, Robbins Geller, The Rosen Law Firm, and Faruqi & Faruqi, LLP. These firms are looking into potential securities law violations related to the company’s statements about Efzofitimod.
The core allegation is that aTyr Pharma and its executives made “false and misleading statements” concerning the drug’s efficacy, particularly its ability to allow patients to completely taper off steroid usage. Investors claim that the company concealed “material adverse facts” about Efzofitimod’s true capabilities while promoting the drug’s potential in a multi-billion-dollar market.
The EFZO-FIT Study and Its Disappointing Results
The class action lawsuits center around the Phase 3 EFZO-FIT study, which evaluated Efzofitimod in patients with pulmonary sarcoidosis. The primary endpoint of the study was the change from baseline in the mean daily oral corticosteroid (OCS) dose at week 48.
However, on September 15, 2025, aTyr Pharma announced that the EFZO-FIT study failed to meet its primary endpoint. This revelation caused the company’s stock price to plummet from $6.03 per share on September 12, 2025, to just $1.02 per share on September 15, 2025.
