– Company’s patented desmopressin oral solution successfully passed pivotal bioequivalence study –
– Company expects to submit New Drug Application (NDA) in April 2025 –
DEER PARK, Ill., March 14, 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 positive results from its bioequivalence study of ET-600, a proprietary, patented oral solution of desmopressin under development for the treatment of central diabetes insipidus.
In a bioequivalence study conducted in 75 human subjects, ET-600 demonstrated pharmacokinetic equivalence to the U.S. Food and Drug Administration (FDA)-approved reference product of the same active ingredient. Healthy adults enrolled in the study were randomly assigned to receive the test and reference drug in an open label, balanced, randomized, single-dose, three-treatment, three-sequence, three-period, three-way crossover oral bioequivalence study. Based on these successful trial results, Eton anticipates submitting an NDA to the FDA for ET-600 in April 2025. If approved, ET-600 would be the only FDA-approved oral liquid formulation of desmopressin.
“We are pleased to see ET-600 pass its pivotal study and move one step closer to reaching patients. Through our deep relationships in the pediatric endocrinology community, we’ve come to appreciate the significant need for a desmopressin medication that can accommodate the precise and titratable doses necessary for pediatric patients. We expect to submit the NDA shortly and have begun pre-launch commercial readiness activities in anticipation of a potential launch in the first quarter of 2026,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals.
