A Phase II Randomized Study of Gemcitabine and Nab-paclitaxel in Combination With S- 1/LV (GASL) or Oxaliplatin (GAP) as First-line Treatment for Metastatic Pancreatic Cancer

• Status: Not yet recruiting
• Trial end date: 2027-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Gemcitabine and nab-paclitaxel are one standard of care for metastatic pancreatic adenocarcinoma (mPDAC) but the progression free survival (PFS) of the regimen is only 5.5 months. Previous phase II study showed gemcitabine and nab-paclitaxel plus cisplatin had a PFS of 10.1 months in mPDAC. However, the nephrotoxicity of cisplatin is always a concern therefore cisplatin was substituted with oxaliplatin in current study. S-1 monotherapy has shown promising anti-tumor activity against PDAC with a manageable safety profile which provided the opportunity of combination with other agents. In this study, we will evaluate the efficacy and safety of gemcitabine, nab-paclitaxel plus S-1/LV (GASL) against gemcitabine, nab-paclitaxel plus oxaliplatin (GAP) in patients with mPDAC.
