Company Summary

Annexon Biosciences is a clinical-stage biopharmaceutical company pioneering the development of a new class of medicines for patients with classical complement-mediated autoimmune, neurodegenerative, and ophthalmic disorders. The company’s pipeline is based on its platform technologies addressing a broad spectrum of well-researched classical complement-mediated autoimmune and neurodegenerative diseases triggered by aberrant activation of C1q, the initiating molecule of the classical complement pathway. Annexon is advancing a portfolio of innovative product candidates designed to block the activity of C1q and the entire classical complement pathway. Annexon is deploying a disciplined, unbiased biomarker-driven strategy designed to improve the probability of technical success of its portfolio and striving to deliver precision medicine to patients with classical complement driven diseases in the body, brain and eye.
