DEER PARK, Ill., March. 15, 2023 (GLOBE NEWSWIRE) — Eton Pharmaceuticals ("Eton" or "the Company") (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today announced the acquisition of rare disease product candidate ET-600 from Tulex Pharmaceuticals. ET-600 is an innovative product candidate under development for the treatment of an endocrinology condition that is estimated to impact less than 5,000 pediatric patients in the United States.

"As a rare disease product that builds on our established presence in pediatric endocrinology, ET-600 is a perfect strategic fit for our portfolio" said Sean Brynjelsen, CEO of Eton Pharmaceuticals. "We have repeatedly heard from physicians about their need for this product to effectively and safely treat their pediatric patients, so we look forward to working to bring this potential new treatment option to market."
