Background of the Investigation
According to the allegations, aTyr and certain executives allegedly made false and/or misleading statements concerning:
• The design and expectations of the Phase 3 EFZO-FIT trial;
• The likelihood that EFZO-FIT would meet its primary steroid-tapering endpoint;
• Representations regarding the drug’s capability to eliminate steroid use.
