根据一份提交给美国证券交易委员会的文件披露，Arvinas Holding Company LLC与辉瑞公司合作的一项协议显示，双方有资格获得总计高达3.2亿美元的里程碑付款，并附有分层结构的特许权使用费安排。
该文件进一步明确了付款的触发条件与具体条款。里程碑款项将基于合作项目的研发进展、监管审批以及商业化成果等多个阶段分期支付。分层特许权使用费则意味着，随着产品销售额达到不同阈值，费率将相应调整，这为双方提供了更具弹性的收益分享机制。
此项财务安排凸显了双方对合作项目前景的信心，也反映了生物医药领域常见的风险共担与收益共享模式。协议的细节虽未完全公开，但高达3.2亿美元的总潜在收益，无疑为项目的后续发展注入了强劲的财务动力。
