DEER PARK, Ill., April 28, 2025 (GLOBE NEWSWIRE) — Eton Pharmaceuticals, Inc (“Eton” or the “Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for ET-600, Eton’s proprietary, patented oral solution of desmopressin under development for the treatment of central diabetes insipidus. The Company expects the application to be assigned a 10-month FDA review, allowing for potential approval and launch in the first quarter of 2026.

“The NDA submission for ET-600 is another important milestone for Eton, and for the thousands of children impacted by diabetes insipidus. If approved, ET-600 will be the only FDA-approved oral liquid formulation of desmopressin, providing the small, precise, and titratable doses required to treat pediatric patients,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals. “Leading pediatric endocrinologists have long expressed a need for this product, and we’re pleased to be one step closer to bringing it to patients. Pre-launch commercial activities are already underway as we plan for a potential approval in the first quarter of 2026.”

Eton has been issued a patent by the U.S. Patent and Trademark Office on ET-600, which expires in 2044 and has additional patent applications under review. In a bioequivalence study conducted in 75 human subjects, ET-600 demonstrated pharmacokinetic equivalence to the FDA-approved reference product of the same active ingredient. The company estimates that central diabetes insipidus impacts approximately 3,000 pediatric patients in the United States.
