About Annexon

Annexon Biosciences is a private, clinical-stage biopharmaceutical company developing a pipeline of novel therapies for patients with classical complement-mediated disorders of the body, eye and brain. The Company’s pipeline is based on its platform technology addressing well-researched classical complement-mediated autoimmune and neurodegenerative disease processes, both of which are triggered by aberrant activation of C1q, the initiating molecule of the classical complement pathway. The Company’s first product candidate, ANX005, is a full-length monoclonal antibody formulated for intravenous administration in autoimmune and neurodegenerative disorders. The Company’s second product candidate, ANX007, is a monoclonal antibody antigen-binding fragment (Fab) formulated for intravitreal administration for the treatment of neurodegenerative ophthalmic disorders. Based on learnings from its initial trials, Annexon is advancing its current programs while evaluating additional orphan and large market indications. Annexon is deploying a disciplined, biomarker-driven development strategy designed to establish that each of its product candidates is engaging the specific target at a well-tolerated therapeutic dose in the intended patient tissue.
