07:20 AM EDT, 03/14/2025 (MT Newswires) -- Eton Pharmaceuticals ( ETON ) said Friday a bioequivalence study of its product candidate ET-600 showed pharmacokinetic equivalence to the U.S. Food and Drug Administration (FDA)-approved reference product of the same active ingredient.

ET-600 is an oral solution of desmopressin under development for the treatment of central diabetes insipidus.

Eton said it expects to submit a new drug application to the agency for ET-600 in April, based on the trial results.
