What was measured

Blood samples were tested to determine if a participant reacted to ramucirumab by producing anti-ramucirumab antibodies. Samples were identified as treatment emergent anti-drug antibody (TE ADA) if the post-treatment sample had an increase of at least 4 fold in titer from pre-treatment values. If the pre-treatment value was not detected or was not present, a 1:20 post-treatment titer was required to indicate treatment emergence. The percentage of participants with TE ADA was calculated as: (the number of participants with TE ADA / total number of participants with at least 1 post-treatment immunogenicity sample analyzed)\*100.

Analysis population: All participants who received study treatment and who had immunogenicity samples analyzed at the specified time points.

Groups in this outcome

Ramucirumab + FOLFIRI

On Day 1 of each 14-day cycle, participants received ramucirumab followed by other study treatment in the following sequence: Irinotecan, Folinic Acid and 5-Fluorouracil. Treatment continued until disease progression, unacceptable toxicity, or other withdrawal criteria were met. Ramucirumab: 8 mg/kg administered intravenously. Irinotecan: 180 mg/m\^2 administered intravenously. Folinic Acid: 400 mg/m\^2 administered intravenously. 5-Fluorouracil: 400 mg/m\^2 bolus immediately followed by 2400 mg/m\^2 continuous infusion.

Placebo + FOLFIRI

On Day 1 of each 14-day cycle, participants received placebo followed by other study treatment in the following sequence: Irinotecan, Folinic Acid and 5-Fluorouracil. Treatment continued until disease progression, unacceptable toxicity, or other withdrawal criteria were met. Placebo: Administered intravenously. Irinotecan: 180 mg/m\^2 administered intravenously. Folinic Acid: 400 mg/m\^2 administered intravenously. 5-Fluorouracil: 400 mg/m\^2 bolus immediately followed by 2400 mg/m\^2 continuous infusion.
