Organon acquired Finnish women's health company Forendo Pharma for $75M upfront plus up to $270M in development/regulatory milestones and up to $600M in commercial milestones (~$954M total); the acquisition closed December 13, 2021. The lead asset, FOR-6219 (later OG-6219), was a first-in-class oral HSD17B1 inhibitor intended as a non-hormonal treatment for endometriosis-related pain. On July 2, 2025, Organon disclosed that the Phase 2 ELENA proof-of-concept study did not demonstrate improvement in moderate-to-severe endometriosis-related overall pelvic pain versus placebo and announced it plans to discontinue the OG-6219 clinical development program — ending the asset that was the central rationale for the deal (Organon had earlier taken a non-cash impairment on the program). Organon stated it remains committed to its women's health pipeline.
