Josh Cohen co-founded Amylyx Pharmaceuticals (NASDAQ: AMLX) in 2013 and continues to serve as its co-CEO. Josh, alongside co-CEO Justin Klee, has overseen the growth of Amylyx -- from its start as a concept dreamed up in a dorm room through its IPO, FDA and Health Canada approvals of its first product, and product launch -- to the company it is today, with a mission to usher in a new era for treating diseases with high unmet needs.
Josh co-invented the oral, fixed-dose combination of sodium phenylbutyrate (PB) and taurursodiol (TURSO, also known as ursodoxicoltaurine), which is being explored for the potential treatment of neurodegenerative diseases. Amylyx’ clinical trial results in collaboration with leading experts have been published in several peer-reviewed medical journals, including the New England Journal of Medicine, Muscle & Nerve, and the Journal of Neurology, Neurosurgery and Psychiatry.
