Company profile

Company website

Annexon, Inc. is a biopharmaceutical company currently engaged in clinical trials, dedicated to the discovery and advancement of therapies for a variety of autoimmune, neurodegenerative, and ophthalmic conditions. Central to its approach is the C1q molecule, which initiates the classical complement pathway. The company targets this pathway to address specific disease mechanisms, such as those seen in antibody-mediated autoimmune disorders and complement-driven neurodegeneration. The company's developmental pipeline features several promising candidates. ANX005, a monoclonal antibody, is in advanced clinical testing, undergoing Phase II/III trials for Guillain-Barré syndrome, as well as Phase II trials for warm autoimmune hemolytic anemia, Huntington's disease, and amyotrophic lateral sclerosis. Another candidate, ANX009, is currently in Phase Ib studies for lupus nephritis. Additionally, ANX007 is progressing through Phase II clinical trials for the treatment of geographic atrophy, an eye disease. Further investigational assets include ANX105, a monoclonal antibody being developed for neurodegenerative indications, and ANX1502, an oral small molecule under investigation for specific autoimmune conditions. Annexon, Inc. was established in 2011 and operates from its headquarters in Brisbane, California.
