In some embodiments, the methods involve the use of a combination of at least two of the following: an inhibitor of indoleamine-2,3-dioxygenase (IDO), an inhibitor of the PD-L1/PD-1 pathway, an inhibitor of CTLA-4, an inhibitor of CD25, or IL-7. The inventors particularly observed a major synergistic effect of combining anti-CTLA-4 with either an IDO inhibitor, with anti-PD-L1 mAb, or with CD-25 depletion. Such combinations have been found to demonstrate a synergistic effect in treating cancer and tumors, for example by reducing tumor size, increasing the percentage of antigen-specific T cells, and increasing T cell function.
在一些实施方案中,这些方法涉及使用以下至少两种药物的组合:吲哚胺-2,3-二氧化酶(IDO)抑制剂、PD-L1/PD-1 通路抑制剂、CTLA-4 抑制剂、CD25 抑制剂或 IL-7。本发明者特别观察到,将抗 CTLA-4 与 IDO 抑制剂、抗 PD-L1 mAb 或 CD-25 清除剂结合使用会产生重大的协同效应。研究发现,这种组合在治疗癌症和肿瘤方面显示出协同效应,例如通过缩小肿瘤大小、增加抗原特异性 T 细胞的比例和提高 T 细胞功能。
