Official Title
A Phase III Second Line Trial of Patients With Gemcitabine Resistant Advanced Pancreatic Cancer (CONKO-003)
Brief Summary

The purpose of this study is to compare best supportive care plus oxaliplatin/ folinic acid/ 5-FU versus best supportive alone in patients with gemcitabine refractory pancreatic cancer.

Detailed Description

Gemcitabine (G) given until progressive disease (PD) is still standard therapy in patients with advanced pancreatic cancer. No standard secondline regimen is available after PD. Best supportive care (BSC) is the main option for these patients. Our phase II study (Pelzer et al, ASCO 2002) showed activity of the OFF (Oxaliplatin/Folinic Acid/5-FU) regimen. To confirm these data we started this multicenter phase III study to examine OFF vs. BSC alone.

165 patients were needed for this study. Following CT/ MRT confirmed PD patients were randomized. Stratification included duration of firstline therapy, Karnofsky Performance Status (KPS) and tumor stage. OFF (outpatient regimen): 5-FU 2g/m² (24h)/FA 200 mg/m² (30min) on d1, d8, d15, d22, additional Oxaliplatin 85mg/m² (2h) on day 8 and 22. Rest on day 23 and 42.

Drug: OFF in experimental arm
OFF was given according to a six week cycle. FA (500 mg/m2 , 0.5h, i.v.) and 5-FU (2,600 mg/m2, 24-hour, i.v.) were administered on days 1, 8, 15, and 22. Oxaliplatin (85 mg/m2 , 2-4 h, i.v.) was administered directly before FA/ 5-FU on days 8 and 22.
