Announced April 28, 2025 and completed July 1, 2025 following regulatory clearances, it is Merck KGaA's largest Healthcare-sector acquisition in nearly two decades. The deal builds a rare-tumor franchise around two FDA-approved commercial products: Ogsiveo (nirogacestat), the first-in-disease systemic therapy for adults with progressing desmoid tumors, and Gomekli (mirdametinib), the first and only FDA-approved therapy for adult and pediatric NF1 patients with symptomatic plexiform neurofibromas not amenable to complete resection. The acquisition is expected to contribute to revenue immediately and to be accretive to EPS pre by 2027. Both assets advanced in the EU around closing: CHMP adopted positive opinions for mirdametinib (May 2025) and nirogacestat (June 2025).
