• Biogen reported 52-week Phase 2 AMETHYST data for litifilimab in cutaneous lupus erythematosus, previously presented at EADV 2026.
• Results showed rapid symptom improvement for patients switching from placebo, with benefits sustained through one year of treatment.
• More patients reached clearer skin over time, supporting litifilimab’s positioning as a potential first-in-class, once-monthly therapy.
• Safety remained consistent with earlier studies, with no new safety signals over the extended treatment period.
• Phase 3 results are expected in the first half of 2027, following FDA Breakthrough Therapy Designation granted in January 2026.
