TOKYO and SUZHOU, China, May 29, 2025 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") and Evopoint Biosciences (Evopoint Biosciences Co., Ltd.) today announced they have entered into an exclusive license agreement for XNW27011, a novel investigational clinical-stage antibody-drug conjugate (ADC) targeting CLDN18.2. The agreement grants Astellas a worldwide (excluding China's mainland, Hong Kong, Macao and Taiwan region) exclusive license to develop and commercialize XNW27011.

XNW27011 is currently being evaluated in a Phase 1/2 study in China in patients with CLDN18.2-expressing solid tumors, including gastric cancer, gastroesophageal cancer and pancreatic cancer. It uses a proprietary topoisomerase I inhibitor payload and linker technology, an approach that has demonstrated clinical success in other approved cancer therapies.

Astellas has significant expertise in developing therapies that target CLDN18.2, including VYLOY^TM, the first CLDN18.2-targeted therapy approved in the world. XNW27011 has the potential to address currently unmet patient need and will expand Astellas' oncology pipeline which currently contains CLDN-targeting therapies utilizing different approaches, as well as ADC's directed to other targets.

Under the terms of the agreement, Evopoint will receive a $130 million upfront payment and is eligible to receive up to $70 million near-term payments, and additional milestone payments associated with development, regulatory and commercialization milestones totaling up to $1.34 billion, as well as royalties on net sales of XNW27011, if approved.
