SpringWorks’ rare tumor portfolio, including a marketed first-in-class, systemic standard-of-care therapy for adults with desmoid tumors and the first and only approved therapy for adults and children with neurofibromatosis type 1 (NF1) who have symptomatic plexiform neurofibromas (PN) not amenable to complete resection, will accelerate immediate and sustainable revenue growth for Merck KGaA, Darmstadt, Germany. SpringWorks’ portfolio complements the progress of Merck KGaA, Darmstadt, Germany, in rare tumors, with Merck KGaA, Darmstadt, Germany, recently exercising an
option for worldwide commercialization
rights for pimicotinib, an investigational therapy developed by Abbisko Therapeutics Co., Ltd. for patients with tenosynovial giant cell tumor (TGCT).
“We have the unique opportunity with SpringWorks to establish a leadership position in rare tumors and build a strong foundation for further investments in this area, where a large unmet medical need exists,” said Peter Guenter, member of the Executive Board and CEO of Healthcare at Merck KGaA, Darmstadt, Germany. “Together, our company and SpringWorks are the perfect combination to improve outcomes for patients with rare tumors and bring therapeutic innovations to more patients worldwide while building on and reinforcing the early success of SpringWorks in the United States. For us, the planned acquisition will create long term, sustainable growth for our Healthcare business. Along with my successor Danny Bar-Zohar, we look forward to completing this strategic transaction and making a meaningful difference for patients whose lives are so profoundly affected by these complex and challenging tumors.”
The agreed acquisition provides SpringWorks with an opportunity to expand its reach into markets beyond the U.S. and leverage the breadth of resources of the global Healthcare organization of Merck KGaA, Darmstadt, Germany.
“From the outset, our focus at SpringWorks has been to create transformative solutions for patients suffering from serious diseases. We have successfully launched two best-in-class medicines in the United States, and with the aspiration to deliver our therapies worldwide, our journey is at a pivotal juncture. It became clear during our discussions with the team of Merck KGaA, Darmstadt, Germany that we share many core values, including a commitment to help more patients with rare tumors live longer, better lives,” said Saqib Islam, CEO of SpringWorks Therapeutics. “We believe that by joining forces with Merck KGaA, Darmstadt, Germany, we are not only creating significant, immediate value for our stakeholders, but we will also be able to leverage their resources and expertise to build a brighter future for the patient communities we seek to serve while also creating new opportunities for SpringWorks employees as part of a global organization.”
SpringWorks’ U.S. Food and Drug Administration (FDA)-approved therapy, OGSIVEO
®
(nirogacestat) is a first-in-class therapy that is the systemic standard of care for the treatment of adult patients with progressing desmoid tumors who require systemic treatment. SpringWorks’ marketing authorization application (MAA) for nirogacestat is under review with the European Medicines Agency (EMA), with a Committee for Medicinal Products for Human Use (CHMP) decision expected in Q2 2025.
GOMEKLI™ (mirdametinib) is the first and only FDA-approved therapy for the treatment of adult and pediatric patients 2 years of age and older with NF1-PN not amenable to complete resection. The FDA’s February 2025 approval of GOMEKLI was based on positive data from SpringWorks’ Phase 2b ReNeu trial, which showed GOMEKLI treatment resulted in a robust objective response rate, deep and durable reductions in tumor volume, and a manageable safety profile. With the approval, SpringWorks was granted a rare pediatric disease priority review voucher by the FDA. The marketing authorisation application for mirdametinib has been validated by the European Medicines Agency (EMA) with a potential approval in 2025. In addition, SpringWorks is advancing its pipeline with additional programs in other tumor settings that are currently underserved.
The transaction has been unanimously approved, by all those in attendance, by both the Merck KGaA, Darmstadt, Germany, and SpringWorks Boards of Directors and is expected to close in the second half of 2025, subject to satisfaction of customary closing conditions, including approval of SpringWorks’ shareholders and receipt of required regulatory approvals.
