What is the Annexon Founding Story?
The story of Annexon Biosciences begins on March 3, 2011. That's when the company was officially incorporated in Delaware, with its main offices in South San Francisco, California. This marked the start of a journey into the world of biotechnology, focusing on innovative treatments for neurodegenerative and autoimmune diseases.
Annexon was brought to life by the vision of two key figures: the late Dr. Ben Barres and Dr. Arnon Rosenthal. Dr. Barres, a respected scientist from Stanford University, contributed his expertise in neurobiology. Dr. Rosenthal, a seasoned industry executive, brought his experience to the table. Their collaboration was sparked by Dr. Barres's research, which highlighted the role of C1q in the progression of neurodegenerative diseases.
Their initial focus was on developing antibody-based treatments to target C1q, aiming to halt the damaging inflammatory processes. This research led to the development of ANX005, one of the company's first major product candidates. The company's approach has always been deeply rooted in research and development, driven by the initial scientific breakthrough.
