China-based Evopoint Biosciences has granted Japan’s Astellas exclusive global rights (excluding Greater China) to develop and commercialise its CLDN18.2-targeting ADC XNW27011, currently in Phase I/II trials in China for CLDN18.2-positive solid tumours. The deal includes USD 130 million upfront, up to USD 70 million in near-term payments and USD 1.34 billion in potential milestones, plus royalties. XNW27011 uses a proprietary topoisomerase I inhibitor payload, while Astellas brings CLDN18.2 expertise including approved therapy Vyloy (zolbetuximab). Both companies highlighted the candidate's potential to address unmet needs in gastric and pancreatic cancers.
