项目摘要

Abstract Pancreatic cancer (PC) has an annual worldwide incidence of more than 495,000 cases and an annual mortality rate of almost 460,000 cases. Most patients are diagnosed late and cannot undergo resection and therefore rely on pharmacotherapy to extend their lives. Current therapies offer only limited benefit due in large part to the dense stroma tissue that surrounds and protects the tumor. Duo Oncology is developing an ultra-small nanoparticle containing, gemcitabine and an immunomodulatory chemokine receptor type 2 antagonist to kill cancer cells and invigorate anti-tumor immunity. These small nanoparticles, less than 30nm in diameter, show enhanced extravasation and tissue penetration, particularly in the PC tumors enriched with dense stroma. Further, research proposed herein will prepare DUO-307 for future IND-enabling studies with formulation optimization, toxicology, and therapeutic efficacy using a cutting edge ex vivo tumor explant model and a clinically-relevant mouse model of PC with dense stroma.

抽象的胰腺癌（PC）的年度发病率超过495,000例，一个年死亡率近460,000例。大多数患者被诊断出来，不能进行切除，因此依靠药物疗法来延长其寿命。当前的疗法仅提供有限的益处，这在很大程度上是由于周围的致密基质组织并保护肿瘤。二人肿瘤学正在开发一个含有的超小纳米颗粒，该纳米颗粒含有吉西他滨和免疫调节性趋化因子受体2型拮抗剂可杀死癌症细胞并激发抗肿瘤免疫力。这些小纳米颗粒，小于30nm 直径显示出增强的渗出和组织穿透，尤其是在PC肿瘤中充满致密基质。此外，本文提出的研究将为未来准备二重奏-307 使用A配方优化，毒理学和治疗疗效的辅助研究最前沿的Ex Vivo肿瘤外植体模型和与PC的临床相关小鼠模型致密基质。
