STOCKHOLM, Sept. 30, 2025 /PRNewswire/ -- EQT Life Sciences, a leading European life sciences venture capital firm, is pleased to share that Genmab (CPH: GMAB) has entered into a definitive agreement to acquire its portfolio company Merus (NASDAQ: MRUS) for a total consideration of USD 8.0 billion. This transaction represents one of the largest M&A deals in European biotech and underscores the value of Merus' innovative clinical pipeline addressing significant unmet needs in oncology.
Merus, based in Utrecht, the Netherlands, is a clinical-stage biotech company developing innovative bispecific and trispecific antibody therapeutics for the treatment of cancer. The company's products include petosemtamab, in development for head and neck squamous cell carcinoma and other malignancies, and zenocutuzumab, an approved product for patients with NRG1 fusion–driven tumors such as pancreatic and lung cancers. Despite significant advances in oncology, patients with these tumor types continue to face poor prognoses and limited treatment options, underscoring the urgent need for more effective therapies.
Over the past year, Merus' lead program petosemtamab, has delivered best-in-class Phase 2 results in both first-line and later-line head and neck cancer, significantly outperforming historical benchmarks and positioning itself as a potential standard-of-care redefining therapy. In addition, Phase 2 trials are ongoing in colorectal cancer in first-, second- and third-line settings. With two FDA Breakthrough Therapy Designations, petosemtamab is well positioned to transform outcomes in head and neck cancer and potentially other oncology indications.
EQT Life Sciences (formerly LSP) first invested in Merus in 2010 from its LSP 4 fund, co-leading the company's first institutional financing. At that time, Merus was still an early-stage preclinical company with a very small team. From 2010 to 2020, EQT was represented on the company's board by Partner John de Koning, providing active strategic support as Merus advanced its pipeline into the clinic and successfully developed multiple antibody programs, including its lead asset.
John de Koning, Partner at EQT and former board member at Merus, said: "It has been a great honor to support Merus from its early beginnings to a NASDAQ-listed clinical-stage biotech with more than 300 employees. The acquisition agreement with Genmab highlights the strength of Merus' innovative platform and pipeline and is a testament to the team's vision and leadership. This landmark transaction not only reflects the company's potential to transform cancer care but also represents one of the largest biotech acquisitions ever in Europe. Importantly, it is also a step toward making better treatments available to patients and improving both quality of care and quality of life, underscoring the importance of venture capital in bringing scientific ideas to patients."
