Brief Summary

Pancreatic adenocarcinoma (PAC) incidence increases regularly in Western countries and it is expected to become the second leading cause of cancer-related mortality in 2020. The prognosis of this disease remains very poor with an overall 5-year survival rate less than 5%.

The FOLFIRINOX regimen (5-fluorouracil [5-FU], folinic acid, irinotecan, and oxaliplatin) and the combination of nab-paclitaxel with gemcitabine demonstrated to be more effective than gemcitabine alone, and are both validated as standard first-line treatment options for metastatic PAC. However, the use of FOLFIRINOX is limited to patients with ECOG performance status (PS) 0-1 and aged less than 75 years. Nab-paclitaxel is currently not reimbursed in France.

Detailed Description

This trial is an open label, multicenter, randomized phase III trial comparing gemcitabine vs FOLFOX in patients with metastatic pancreatic adenocarcinoma and non-fit for FOLFIRINOX. Adults fulfilling inclusion criteria and non-inclusion criteria will be randomized between a FOLFOX arm and a gemcitabine arm. The primary endpoint is the overall survival (OS) at 24 months. The secondary objectives are : objective response rate and disease control rate (RECIST v1.1, in case of evaluable lesion), duration of response, duration of disease control, progression free survival (PFS), the evolution of biomarkers Ca 19-9 and CEA under treatment, the toxicities according to International Common Terminology Criteria for Adverse Events (CTCAE) version 4.0, the safety of both arms, the quality of life, the dose intensity (DI) of each protocol, the Quality-Adjusted Survival, and the rate and type of second-line / third-line regimens chemotherapy. With an expected median survival time in the control group of 5 months, an accrual period of 3 years and a minimum follow-up period of 2 years, a total of 199 patients per group are required to detect a hazard ratio of 0.75 based on a 5% two-sided type I error rate and a power of 80%, leading to a total number of 400 patients to include.
