“In the third quarter we made advances that underscore the potential of our late-stage portfolio; Epcoritamab moved closer to being available to patients in earlier lines of therapy for follicular lymphoma and Rina-S was granted Breakthrough Therapy Designation (BTD) in advanced endometrial cancer. With robust development plans for both epcoritamab and Rina-S and with Tivdak® (tisotumab vedotin) now available for prescribing in Germany - our first commercial entry into a European market - we continue to execute on our strategic imperatives to accelerate our late-stage pipeline and maximize our approved medicines to reach more patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab. “In addition, our proposed acquisition of Merus provides us with the potential to add petosemtamab, a late-stage asset with two BTDs, to our late-stage portfolio. This proposed transaction is expected to meaningfully accelerate our shift to a wholly owned model, driving sustained growth into the next decade and contributing to our evolution into a global biotechnology leader.”
