BRISBANE, Calif., Jan. 07, 2024 (GLOBE NEWSWIRE) -- Annexon, Inc. (Nasdaq: ANNX), a clinical-stage biopharmaceutical company developing a new class of complement-based medicines for people living with devastating inflammatory-related diseases, today outlined its strategic priorities for 2024 with late-stage clinical milestones, including ANX005 for Guillain-Barré syndrome (GBS), ANX007 for geographic atrophy (GA) and its first-in-kind oral small molecule complement inhibitor, ANX1502, for a range of autoimmune indications.

“Our distinct classical complement portfolio has been built over 10 years of research focused on stopping C1q-driven inflammation activated on diseased tissue in complement-mediated diseases of the body, brain and eye. The robust and consistent functional outcome data generated by our flagship and next wave programs has reinforced our founding thesis of stopping the classical complement disease process where it starts,” said Douglas Love, president and CEO of Annexon.

“This is a pivotal time for Annexon, with registration programs for our two lead candidates, numerous late- and mid-stage clinical catalysts expected across our portfolio, and a strong balance sheet to fuel our priority programs to meaningful inflection points. We are proud of what we’ve accomplished over our decade-long history and are excited by the potential to achieve our goal of bringing transformative therapies to millions of patients with debilitating autoimmune, ophthalmic and neurodegenerative diseases.”
