Key Developments in Therapeutic Initiatives
FDA Meeting for Tanruprubart
A pivotal FDA meeting is planned for the second quarter of 2025 concerning Tanruprubart, previously known as ANX005. This therapy is anticipated to be the first targeted treatment for Guillain-Barré Syndrome (GBS), a rare but serious condition affecting the nervous system. Annexon's upcoming discussions with the FDA are crucial as they prepare for a Biologics License Application (BLA) submission. The innovative treatment is backed by extensive research demonstrating its ability to reduce neuroinflammation and promote recovery.
FORWARD Study Launch
The open-label Tanruprubart FORWARD study is set to begin in North America and Europe in the second quarter of 2025. This study aims to broaden the understanding and experiences of patients and healthcare professionals with Tanruprubart’s single infusion treatment regimen, enhancing patient access to groundbreaking therapy.
Progress in ANX007 for Dry AMD
In parallel, Annexon is progressing with ANX007, which targets dry age-related macular degeneration (AMD) with geographic atrophy (GA). Positioned to be the first vision-preserving treatment of its kind, ANX007 has the potential to reshape the therapeutic landscape for over eight million patients globally. The Phase 3 ARCHER II trial is currently underway, and accelerated enrollment is on track for completion in the third quarter of 2025, with pivotal data expected in the latter half of 2026.
