ORR is confirmed best overall tumor response of CR or PR. According to RECIST v1.1, PR defined as a >30% decrease in the sum of the longest diameters (LD) of the target lesions, taking as reference the baseline sum of the LD; CR was defined as the disappearance of all target and non-target lesions. Percentage of participants was calculated as: total number of participants with a best tumor response of PR or CR among participants counted in the denominator/total number of participants treated with any amount of study drug, who has a complete radiographic assessment at baseline, and who has at least 1 complete radiographic assessment at postbaseline x 100%.

All participants who received any amount of study treatment and had evaluable baseline and postbaseline data for radiographic assessment.

Overall survival (OS) duration is defined from the date of first dose of study drug to the date of death from any cause. OS was estimated by the Kaplan-Meier method. For participants who were not known to have died as of the data cut-off date, OS was censored at the date of last contact prior to the data cutoff date.

All participants who received any amount of study treatment. Participants censored=34.

PFS is defined as the time from the date of first dose of study drug until objective progressive disease (PD) or death for any cause. According to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), PD was at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. In addition to the 20% relative increase, the sum must have also demonstrated an absolute increase of at least 5 millimeters (mm). The appearance of 1 or more new lesions was also considered progression. For participants not known to have died as of the data cut-off date and who do not have objective PD, PFS will be censored at the date of the last complete radiographic assessment.

All participants who received any quantity of study treatment.

DCR is best overall response of SD, PR or CR. According to RECIST v1.1, PR defined as a ≥30% decrease in the sum of the longest diameters (LD) of the target lesions, taking as reference the baseline sum of the LD; CR was defined as the disappearance of all target and non-target lesions. SD was neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD, taking as reference the smallest sum diameter since treatment started. Percentage of participants who achieved disease control = (those participants counted in the denominator with a best tumor response of SD, PR, or CR)/(the same denominator as for ORR)*100.

All participants who received any quantity of study treatment and had evaluable baseline and postbaseline data for radiographic assessment.

CTS is defined as maximum percent improvement from baseline in the sum of target lesions.

All participants who received any quantity of study treatment and had evaluable baseline and postbaseline data for CTS.

Pre-infusion Minimum Concentration (Cmin) and post-infusion (Cmax) necitumumab serum concentration

All participants who received any amount of study treatment and had evaluable data for Cmax

A participant was considered to have an anti-necitumumab antibody response if anti-drug antibodies (ADA) were detected at any time point. Treatment emergent antibodies were defined as any anti-necitumumab antibody titer equal to or greater than 4-fold the participant's baseline titer.

All participants who received any amount of study treatment and had evaluable baseline and postbaseline data for antibodies.
