Overview

• Notices reflect competing class periods, with some defining January 16–September 12, 2025, while others cite November 7, 2024–September 12, 2025.
• Complaints allege false or misleading statements about the Phase 3 EFZO-FIT forced-taper design and efzofitimod’s capacity to permit complete steroid withdrawal.

• Firms note a class action has been filed but no class is certified, and investors may choose to remain absent class members or select counsel of their choice.
