ETON Eton Pharmaceuticals Inc

Eton Pharmaceuticals, Inc (“Eton” or the “Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today announced that it has acquired the U.S. rights to Amglidia (glyburide oral suspension, known as glibenclamide in Europe) for the treatment of neonatal diabetes mellitus from AMMTeK.

“This exciting transaction adds another attractive, patented product candidate to our growing pediatric endocrinology portfolio. In addition, the product aligns with Eton’s expertise and wealth of experience in bringing to market liquid and precision dose formulations for pediatric patients,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

“Currently, there are no FDA-approved oral treatments for neonatal diabetes mellitus. Amglidia has been used successfully to treat European patients for years, and families and pediatric endocrinologists have expressed to us the significant need for this treatment in the United States. We look forward to working with AMMTeK to bring the product to U.S. patients as quickly as possible,” concluded Brynjelsen.

Amglidia is a proprietary, patented liquid product that was developed for the treatment of neonatal diabetes mellitus by AMMTeK, a French biotechnology company. The product was approved by the EMA in 2018. The product has already been granted Orphan Drug Designation by the U.S. FDA. Neonatal diabetes mellitus is a rare condition estimated to impact approximately 300 patients in the United States. Currently, there are no FDA-approved oral treatment options and as a result, U.S. patients frequently either rely on compounded products that are not FDA-approved or administer products off-label by making homemade suspensions.

AMMTeK has conducted a post-approval study tracking five years of real-world safety and efficacy in European patients, which will be used to support Eton’s NDA submission. Eton plans to hold a meeting with the FDA in the first quarter of 2025 and anticipates submitting an NDA for the product in 2026.
