Conditions

PDAC - Pancreatic Ductal Adenocarcinoma

Keywords

PDAC, sitagliptin

Brief summary

The purpose of this study is to determine the efficacy of sitagliptin combined with gemcitabine and albumin-bound paclitaxel in subjects with locally advanced and metastatic pancreatic ductal adenocarcinoma.

Detailed description

This is a single-institution, prospective, open, one-armed phase Ⅱ clinical trial of sitagliptin combined with gemcitabine and nab-paclitaxel.

Interventions

DRUGCombination of sitagliptin+ gemcitabine + nab-paclitaxel

Drug1: Sitagliptin will be administered orally once a day at a dose of 100 mg depending on cohort assignment. Drug2: Gemcitabine will be intravenously administered on Days 1 and 8 of every 21-day cycle at a dose of 1000 mg/m2 depending on cohort assignment. Drug3: Nab-Paclitaxel will be intravenously administered on Days 1 and 8 of every 21-day cycle at a dose of 125 mg/m2 depending on cohort assignment.
