About Amylyx Pharmaceuticals
Pharmaceutical Preparations, SIC 2834
Amylyx Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company that discovers and develops therapies for endocrine disorders and neurodegenerative diseases. Its pipeline includes avexitide, an investigational glucagon-like peptide-1 receptor antagonist undergoing evaluation for post-bariatric hypoglycemia and congenital hyperinsulinism. The company also advances AMX0035 for Wolfram syndrome, AMX0114 for amyotrophic lateral sclerosis, and AMX0318 for metabolic and rare conditions. Because its drug candidates remain in clinical and preclinical development, the company currently serves patient populations and study participants affected by these underserved medical conditions rather than commercial consumers.
The company conducts clinical trials across multiple medical centers, including twenty-one study sites in the United States for its lead trial. Its research initiatives, academic partnerships, and patent rights span international jurisdictions, including the United States, Canada, and Europe. Amylyx contracts external manufacturing organizations for the clinical production and packaging of its investigational products. The provided text does not identify the location of the company's corporate headquarters.
