JERSEY CITY, N.J. & TURKU, FINLAND – Organon (NYSE: OGN), and Forendo Pharma today announced that the companies have entered into a definitive agreement, under which Organon will acquire Forendo, a clinical-stage drug development company focused on novel treatments in women's health. Forendo is pioneering the science of intracrinology, addressing disease through a novel, tissue-specific approach. Its lead clinical compound is an investigational, potentially first-in-class oral 17β-hydroxysteroid dehydrogenase type 1 (HSD17B1) inhibitor in early clinical development for endometriosis, being evaluated for its potential effect on endometriotic lesions. Endometriosis is a common and chronic condition that affects up to 1 in 10 women of reproductive age, causes abdominal pain and is associated with infertility.
