The pt has received first-line combination therapy of an oxaliplatin containing regimen (re-challenge after drug holiday with same regimen is allowed) for metastatic disease and a)experienced radiographic disease progression during first-line therapy, or b)experienced radiographic disease progression within 6 months after the last dose of first-line therapy, or c) discontinued part or all of first-line therapy due to toxicity and experienced radiographic disease progression within 6 months after the last dose of first line therapy. - 5. Fresh (new) tumor biopsy (24 hour formalin fixed and shipped wet in 70% Ethanol) must be shipped to the central laboratory prior to randomization.A minimum of 11 evaluable slides must be available for analysis.Only KRAS and EGFR data generated from the fresh (new) tumor biopsy will be considered for the inclusion and stratification of the pt respectively. - 6.
