BRISBANE, Calif., Jan. 08, 2023 (GLOBE NEWSWIRE) -- Annexon, Inc. (Nasdaq: ANNX), a clinical-stage biopharmaceutical company developing a new class of complement medicines for patients with classical complement-mediated autoimmune, neurodegenerative and ophthalmic disorders, today reported progress across its broad portfolio of complement therapies and outlined its focus on four flagship programs to support its advancement to a late-stage biopharmaceutical company developing first-in-class treatments for complement-mediated diseases of the body, brain and eye.

Annexon has prioritized resources and execution of late-stage development of its four flagship programs: Guillain-Barré syndrome (GBS), Huntington’s disease (HD), geographic atrophy (GA) and its first-in-kind oral small molecule, ANX1502. In so doing, Annexon’s goal is to create near-term value for patients, physicians and stakeholders with the achievement of the following objectives by the end of 2023:

“At Annexon, we envision a world in which every person gets to live out their talents, without being robbed of their physical and cognitive health due to disease. Our mission is to free the body, brain and eye from diseases driven by the classical complement cascade,” said Douglas Love, president and CEO of Annexon. “To achieve this, we’ve purposefully developed a broad pipeline across three therapeutic franchises – autoimmune, neurodegeneration and ophthalmology – allowing us to rigorously evaluate an array of diseases for which the classical pathway drives disease burden. Based on data and learnings generated to-date, we’re advancing four flagship programs that each have game-changing potential for patients and their families.”

Love continued, “Throughout 2022, we made significant progress across our pipeline and our business, setting up a strong foundation for growth and multiple catalysts on the horizon in 2023 and beyond. We’re encouraged by the recent engagements with the FDA on the pivotal trial design for ANX005 in two indications – GBS and HD – and are well-underway with our flagship program for GA, with initial clinical data anticipated mid-year. Across each therapeutic franchise, we’ve shown that our approach to stopping the classical pathway at its start can have a measurable impact on devastating and difficult-to-treat diseases.”

“This is a remarkable time in the evolution of Annexon. Since the company was founded, the field of complement therapeutics has advanced dramatically. I am proud of the role Annexon has played in revolutionizing complement biology, carrying on our founders’ legacy with ground-breaking discoveries in the brain-body-eye connection,” stated Mr. Love. “Today, we have an extensive complement pipeline in development with several late-stage trials underway, and a strong balance sheet and disciplined investment approach that supports our near- and long-term plans for our company. Together with a passionate and talented team, we have an incredible opportunity to achieve something tremendous in the field of medicine, and I am excited and confident in the future ahead for us and most importantly, for patients.”
