An exploratory study of treatment sensitivity and prognostic factors in a efficacy and safety study of mFOLFOX6 + bevacizumab versus mFOLFOX6 + panitumumab therapy in patients with chemotherapy-naive unresectable advanced or recurrent colorectal cancer

Intervention name : mFOLFOX6 + panitumumab
INN of the intervention : Fluorouracil, calcium levofolinate, oxaliplatin, panitumumab
Dosage And administration of the intervention : Group P; OXA: 85 mg/m2/day 1, l-LV: 200 mg/m2/day 1, 5-FU iv: 400 mg/m2/day 1, 5-FU civ: 2400 mg/m2/day 1-3, panitumumab: 6 mg/kg; mFOLFOX6 + panitumumab combination therapy, once every two weeks
Control intervention name : mFOLFOX6 + bevacizumab
INN of the control intervention : Fluorouracil, calcium levofolinate, oxaliplatin, bevacizumab
Dosage And administration of the control intervention : Group B; OXA: 85 mg/m2/day 1, l-LV: 200 mg/m2/day 1, 5-FU iv: 400 mg/m2/day 1, 5-FU civ: 2400 mg/m2/day 1-3, bevacizumab: 5 mg/kg; mFOLFOX6 + bevacizumab combination therapy, once every two weeks
Primary outcome(s): exploratory
Overall survival (OS)
Timeframe: Up to approximately 63 months
OS obtained in the main study will be stratified by the presence or absence of mutation of tumor-associated genes in tumor tissues at the baseline of the main study evaluate the relationship between OS and gene mutations. OS will be measured as the time from the date of randomization to the date of death due to any causes.
Study Design: Exploratory analysis
