The time from date of randomization to date of death due to any cause. For participants who were alive, overall survival was censored at the last contact.

Full (intent-to-treat) analysis set, which included all participants randomized regardless of treatment received.

Time from randomization to date of first documentation of progression or death due to any cause, whichever came first. Participants last known to be alive and progression-free, who had a baseline and at least 1 on-study disease assessment, were censored at last disease assessment verifying lack of progression. Progression was determined by the investigator per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0, as a 20% increase in the sum of the longest diameter of target lesions, or target lesions over nadir, unequivocal progression of non-target disease, or the appearance of new lesions.

Full (intent-to-treat) analysis set, which included all participants randomized regardless of treatment received.

Percentage of participants with objective response (OR) based on assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0. CR are defined as complete disappearance of all lesions (target and/or non target). PR are those with at least 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions.

Due to futility, the study was terminated early; therefore pharmacokinetic data were not analyzed.

ADAs are immunogenicity indicators to figitumumab. Participants reporting positive for ADAs are indicated by an endpoint titer of no less than 6.64.

Analysis population included all participants treated with figi. Data are combined for "figi+erlo" and "erlo then figi" because the objective was to report any participants with positive ADA after exposure to figi regardless of figi administration order, rather comparison of these 2 treatment groups. N=number of participants evaluable.

Due to futility, the study was terminated early; therefore biomarker results were not analyzed.

EQ-5D is a participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state. Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state.

Due to futility, the study was terminated early; therefore EQ-5D data were not analyzed.

EORTC QLQ-C30 includes functional scales (physical, role, cognitive, emotional, and social), global health status, symptom scales (fatigue, pain, nausea/vomiting) and single items (dyspnoea, appetite loss, insomnia, constipation/diarrhea and financial difficulties). Most questions use 4 point scale (1 'Not at all' to 4 'Very much'; 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). Scores averaged, transformed to 0-100 scale; higher score=better level of functioning or greater degree of symptoms.

This outcome measure was added in Protocol Amendment 3 (28 January 2010). However, data were not collected as the majority of the subjects had already been enrolled prior to this amendment and the study was terminated shortly thereafter (02 March 2010).

QLQ-LC13 consists of 13 questions relating to disease symptoms specific to lung cancer and treatment side effects typical of treatment with chemotherapy and radiotherapy. The 13 questions comprise 1 multi-item scale for dyspnea and 10 single-item symptoms and side effects (coughing, hemoptysis, sore mouth, dysphagia, peripheral neuropathy, alopecia, chest pain, arm pain, other pain, and medicine for pain). Recall period: past week; response range: not at all to very much. Scale score range: 0 to 100. Higher symptom score = greater degree of symptoms.
