Disclosed herein are methods and compositions for enhancing an immune response to a solid tumor in a subject. In some embodiments, a method comprises: (a) administering to the subject a hypoxia-activated bioreductive agent (HABA); (b) inducing hypoxia by (i) administering a hypoxia-inducing agent to the subject or (ii) embolizing one or more blood vessels supplying the solid tumor; and (c) administering an immune checkpoint inhibitor prior to, simultaneously with, or subsequent to step (b) in an amount effective to enhance an immune response to the solid tumor, as compared to an immune response in the absence of the immune checkpoint inhibitor. Kits for use in the disclosed methods are also provided.
本文公开了用于增强受试者对实体瘤的免疫应答的方法和组合物。在一些实施方案中,方法包括(a) 向受试者施用缺氧激活的
生物还原剂(HABA);(b) 通过(i)向受试者施用缺氧诱导剂或(ii)栓塞供应实体瘤的一个或多个血管来诱导缺氧;以及(c)在步骤(b)之前、同时或之后施用免疫检查点
抑制剂,施用量有效于增强对实体瘤的免疫应答,与不施用免疫检查点
抑制剂时的免疫应答相比。还提供了用于所公开方法的试剂盒。
