Study Endpoints

Primary Endpoints

Compare overall survival in subjects with previously-treated metastatic, epidermal growth factor receptor (EGFR)-positive colorectal cancer treated with oxaliplatin, 5-FU, and LV (FOLFOX4) and cetuximab with FOLFOX4 alone.
Every six weeks
Number of Participants Who Had Treatment-Emergent Adverse Events (TEAEs); Data Analysis Cut-Off: September 27, 2013
Part 2: Baseline to end of combination therapy (up to 18 weeks)

September 27, 2013 is the date when data was last collected for the primary endpoint. Prior to this date, the manufacturing process for the BI-manufactured cetuximab was changed necessitating the need to switch participants to US commercial cetuximab. All other components of their treatment regimen remained unchanged and participants stayed in their original reporting group. Therefore, the number of participants in the BI-manufactured cetuximab treatment arm who had TEAEs includes TEAEs while participants received BI-manufactured and US-commercial cetuximab. Using September 27 cut-off, the analysis of TEAEs is confounded by the switch from BI-manufactured to US commercial cetuximab. TEAEs were defined as serious and other non-serious AEs that occurred or worsened after study treatment (regardless of causality). TEAE information for Safety Lead-In group available in Reported Adverse Events module which is summary of serious and other non-serious AEs regardless of causality.

Number of Participants Who Had TEAEs; Data Analysis Cut-Off: January 23, 2013
Part 2: Baseline to end of combination therapy or date first participant switched to US commercial cetuximab (up to 18 weeks)

January 23, 2013 is the date when the first participant in the BI-manufactured cetuximab treatment arm switched to US commercial cetuximab due to changes in the manufacturing process for the BI-manufactured cetuximab necessitating the need to switch participants to US commercial cetuximab. Each participant who switched treatments received at least 2 cycles of BI-manufactured cetuximab before switching. All other components of their treatment regimen remained unchanged. The number of participants who had TEAEs during combination therapy is reported. Using January 23 cut-off, data is un-confounded by lack of BI-manufactured cetuximab. TEAEs were defined as serious and other non-serious adverse events (AEs) that occurred or worsened after study treatment (regardless of causality). TEAE information for Safety Lead-in group available in Reported Adverse Event module which is summary of serious and other non-serious AEs regardless of causality.
