The ability of tumor cells to evade apoptosis is currently a major problem in anti-tumor therapy. IAPs are an important class of apoptosis-regulating proteins. APG-1387, a potent bivalent SMAC mimetic, small molecule of IAP inhibitor, which could inhibit pancreatic cancer proliferation as monotherapy and in combination with chemotherapy through apoptosis pathway.~It's an open label, multiple centers phase Ib/II Study. Safety and tolerability of APG1387 combined with nab-paclitaxel and gemcitabine will be evaluated in phase Ib in previously-treated, advanced pancreatic adenocarcinoma patients. Efficacy and tolerability will be evaluated in phase II study in first line standard treatment failed metastatic pancreatic adenocarcinoma patients.
This study is a two stage study consisting of a dose escalation phase Ib and a phase II study which include subjects with previously-treated, advanced pancreatic adenocarcinoma. Dose Limiting Toxicities (DLTs) and maximum tolerated dose (MTD) of APG1387 in combination with nab-paclitaxel and gemcitabine will be evaluated in the dose escalation phase Ib. Safety and efficacy of APG1387 plus gemcitabine and nab-paclitaxel will be evaluated in phase II.
