March 01, 2022

Multiple Value-Creating Catalysts Across Complement-Targeted Portfolio Anticipated Through 2023

Encouraging Interim Data Reported from Phase 2 Study of ANX005 for Huntington’s Disease; Full Data Expected in the Second Quarter of 2022

$243 Million in Cash and Investments at End of 2021; Operating Runway into First Quarter of 2024

BRISBANE, Calif., March 01, 2022 (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 announced recent highlights and reported fourth quarter and full year 2021 financial results.

“2021 was a year of marked progress across our pipeline, which is uniquely designed to provide greater protection against complement-mediated disorders of the body, brain and eye by stopping the classical complement pathway at its start, C1q,” said Douglas Love, Esq., president and chief executive officer of Annexon. “The favorable early data generated with ANX005 in both Guillain-Barré Syndrome and Huntington’s disease – autoimmune and neurodegenerative diseases, respectively – support our approach to fully inhibiting C1q and support the ongoing development with our lead candidate. In addition, given the known role that aberrant activation of C1q plays in driving a wide range of diseases, we are actively advancing our pipeline across three therapeutic franchises, with numerous clinical data readouts and new study initiations anticipated over the course of 2022 and 2023. This is an exciting time for Annexon, and I am confident in our potential to deliver game-changing medicines to patients in need.”

About Annexon
Annexon (Nasdaq: ANNX) is a clinical-stage biopharmaceutical company pioneering a new class of complement medicines designed to stop the classical complement pathway at its start, C1q, to bring therapies to patients with classical complement-mediated autoimmune, neurodegenerative, and ophthalmic disorders. The company’s proprietary complement-targeting platform utilizes well-researched classical complement-mediated autoimmune and neurodegenerative processes triggered by aberrant activation of C1q, the initiating molecule of the classical complement pathway. Annexon is advancing a broad portfolio of innovative product candidates designed to block the activity of C1q and the entire classical complement pathway, which may provide more complete protection against complement-mediated disorders of the body, brain and eye. The company’s pipeline includes three clinical-stage drug candidates, ANX005 (intravenous administration), ANX007 (intravitreal administration), and ANX009 (subcutaneous administration), as well as a robust early-stage pipeline of preclinical and discovery stage programs. Annexon is deploying a disciplined, biomarker-driven strategy designed to improve the probability of technical success of its portfolio. For more information, visit
