Primary Outcome Measures

Name	Time	Method
Number of Participants With One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration	First Dose to Study Completion Plus 30-Day Safety Follow-Up (Up To 22 Months)	Clinically significant events were defined as serious adverse events (SAE). A summary of other nonserious AEs, and all SAE's, regardless of causality, is located in the Reported Adverse Events section.

Secondary Outcome Measures

Name	Time	Method
Pharmacokinetics (PK): Minimum Serum Concentration (Cmin) of Ramucirumab	Day 8, Day 22, Day 29, Day 43, Day 50, Day 64, Day 71, Day 85, Day 92 and Day 106: Pre-Dose	Minimum Serum Concentration (Cmin) of Ramucirumab.
Percentage of Participants With Complete Response (CR) or Partial Response (PR) (Objective Response Rate)	First Dose to Date of Objective Progressive Disease or Death Due to Any Cause (Up To 22 Months)	Objective response rate (ORR) was defined as the percentage of randomized participants achieving a best confirmed overall response of CR or PR using Response Evaluation Criteria in Solid Tumors (RECIST v1). CR was defined as the disappearance of all target and non-target lesions. PR was defined as at least a 30% decrease in the sum of the longest diameters (LD) of target lesions, taking as reference the baseline sum LD and no progression in non-target lesions.
Number of Participants With Treatment Emergent Anti-Ramucirumab Antibodies (TE-ADA)	First dose to study completion plus 30-day safety follow-up (Up To 22 Months)	Number of participants with positive treatment emergent anti-ramucirumab antibodies was summarized by treatment group.
Pharmacokinetics (PK): Maximum Serum Concentration (Cmax) of Ramucirumab	Day 1, Day 8, Day 43, Day 50, Day 85 and Day 92: End of Infusion	Maximum Serum Concentration (Cmax) of Ramucirumab.
