What Happened?

On September 15, 2025, aTyr announced that the Phase 3 study of its intravenous Efzofitimod pulmonary sarcoidosis treatment, EFZO-FIT, did not meet its primary endpoint in change from baseline in mean daily OSC dose at week 48.

On this news, aTyr’s stock price fell $5.01, or 83.2%, to close at $1.02 per share on September 15, 2025, thereby injuring investors.

What Is The Lawsuit About?

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) Defendants created adverse facts concerning aTyr’s study design for EFZO-FIT, giving the false impression that Efzofitimod would meet its primary endpoint; (2) Defendants crafted a narrative that the Phase 3 EFZO-FIT study would provide a way for patients to fully remove steroids from their treatment plans; (3) there may be other factors that permit patients to completely remove steroids from their treatment plans; (4) thus, their Phase 3 EFZOFIT study failed to meet the primary endpoint in change from baseline in mean daily OCS dose at week 48; and (5) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
