Nab-paclitaxel Plus S-1(AS) Versus Nab-paclitaxel Plus Gemcitabine(AG) in Patients With Advanced Pancreatic Cancer

Brief summary public domain (ClinicalTrials.gov)

This is a randomized phase II trial comparing the first-line treatment with nab-paclitaxel plus S-1(AS) and nab-paclitaxel plus gemcitabine(AG) in advanced pancreatic ductal adenocarcinoma (PDA) with primary tumor nonexcision in Chinese patients.

Detailed description public domain (ClinicalTrials.gov)

Advanced pancreatic ductal adenocarcinoma (PDAC) is an aggressive and chemo-resistant disease with extremely low 5-year survival rate. Gemcitabine has been the cornerstone of metastatic PDAC treatment for more than a decade , although survival benefit was very poor. Nab-paclitaxel added to gemcitabine has showed improving survival and overall response rate vs gemcitabine alone in metastatic PDAC first-line treatment in the MPACT phaseIII study, which represents one of the standards of care in advanced PDAC therapy. S-1 is an oral 5-fluorouracil (5-FU) prodrug, and shown to be non-inferior to gemcitabine on OS for unresectable pancreatic cancer. Meanwhile, adjuvant chemotherapy with S-1 monotherapy was found to significant prolong survival of pancreatic cancer patients when compared with gemcitabine. This study is to explore the efficacy and safety of nab-paclitaxel plus S-1(AS) and nab-paclitaxel plus gemcitabine(AG) as first-line treatment in advanced pancreatic ductal adenocarcinoma (PDA) with primary tumor nonexcision in Chinese patients.
