Patients with pancreatic adenocarcinoma (PDAC) have a 5-year survival rate of 8%, the lowest of any cancer in the United States. Traditional chemotherapeutic regimens, such as gemcitabine- and fluorouracil-based regimens, often only prolong survival by months. Effective precision targeted therapy is therefore urgently needed to substantially improve survival. In an effort to expedite approval and delivery of targeted therapy to patients, we utilized a platform to develop a novel combination of FDA approved drugs that would target pancreaticoduodenal homeobox1 (PDX1) and baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) utilizing super-promoters of the target genes to interrogate an FDA approved drug library. We identified and selected metformin, simvastatin and digoxin (C3) as a novel combination of FDA approved drugs, which were shown to effectively target PDX1 and BIRC5 in human PDAC tumors in mice with no toxicity.

胰腺腺癌 (PDAC) 患者的 5 年生存率为 8%，是美国所有癌症中最低的。传统的化疗方案，例如基于吉西他滨和氟尿嘧啶的方案，通常只能将生存期延长数月。因此，迫切需要有效的精准靶向治疗来显着提高生存率。为了加快批准和向患者提供靶向治疗，我们利用一个平台开发了一种新的 FDA 批准药物组合，该药物将靶向胰十二指肠同源框1（PDX1）和杆状病毒凋亡重复抑制剂 5（BIRC5），利用超级目标基因的启动子询问 FDA 批准的药物库。我们确定并选择了二甲双胍、辛伐他汀和地高辛 (C3) 作为 FDA 批准药物的新组合，
