In certain embodiments a platform technology for the facilitating immune therapy in the treatment of cancer is provided. In certain embodiments nanocarriers are provided that facilitate delivery of an IDO inhibitor in conjunction with an inducer of cell death (ICD-inducer). In certain embodiments the IDO inhibitor is conjugated to a component of a lipid bilayer forming a nanovesicle. In still another embodiment, methods and compositions are provided where an ICD-inducing agent (e.g., doxorubicin, oxaliplatin, mitoxantrone etc.) and an IDO pathway inhibitor (e.g., an IDO inhibitor-prodrug) are integrated into a nanocarrier (e.g. a lipid-bilayer (LB)-coated nanoparticle), that allows systemic delivery to orthotopic pancreatic cancer site.
在某些实施例中,提供了一种用于促进免疫疗法治疗癌症的平台技术。在某些实施例中,提供了一种纳米载体,可促进与细胞死亡诱导剂(ICD诱导剂)一起传递IDO抑制剂。在某些实施例中,IDO抑制剂与脂质双层的组分结合形成纳米囊泡。在另一实施例中,提供了一种方法和组合物,其中ICD诱导剂(例如多柔比星、奥沙利铂、米托蒽醌等)和IDO途径抑制剂(例如IDO抑制剂前药)被整合到一个纳米载体(例如脂质双层(LB)包被的纳米粒子)中,从而实现对原位胰腺癌部位的全身传递。
