A Study of Ramucirumab (LY3009806) in Combination With Erlotinib in Previously Untreated Participants With EGFR Mutation-Positive Metastatic NSCLC (RELAY)

Part B: Overall Survival (OS)

OS was defined as the time from the date of randomization to the date of death from any cause. For each participant who was not known to have died as of the data-inclusion cutoff date for a particular analysis,OS was censored for that analysis at the date of last contact prior to the data-inclusion cutoff date (contacts considered in the determination of last contact date include adverse event (AE) date, lesion assessment date, visit date, and last known alive date).

Time frame: Randomization to Date of Death from Any Cause (Up To 37 Months)

Part B: Percentage of Participants With Complete Response (CR) or Partial Response (PR) (Objective Response Rate [ORR])

ORR was defined as the percentage of randomized participants achieving a best overall response of partial response (PR) or complete response (CR) assessed via Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CR was defined as the disappearance of all lesions, pathological lymph node reduction in short axis to \<10 mm, and normalization of tumor marker levels of non-target lesions. PR was at least a 30% decrease in the sum of diameter of target lesions, taking as reference the baseline sum diameters. Progressive Disease (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 relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of 1 or more new lesions is also considered progression.

Time frame: Randomization to Progressive Disease (Up To 37 Months)

Part B: Percentage of Participants With CR, PR, or Stable Disease (SD) (Disease Control Rate [DCR])

DCR was defined as the percentage of randomized participants achieving a best overall response of CR,PR, or stable disease(SD) assessed via Response Evaluation Criteria in Solid Tumors(RECIST) version 1.1. CR was defined as the disappearance of all lesions,pathological lymph node reduction in short axis to \<10 mm, and normalization of tumor marker levels of non-target lesions.PR was at least a 30% decrease in the sum of diameter of target lesions, taking as reference the baseline sum diameters.SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Progressive Disease(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 relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.The appearance of 1 or more new lesions is also considered progression.

Time frame: Randomization to Progressive Disease (Up To 37 Months)

Part B: Duration of Response (DoR)

DoR was defined as the date of first documented CR or PR (responder) to the date of progressive disease or the date of death due to any cause, whichever was earlier. If a responder was not known to have died or have progressive disease, then the participant was censored at the date of last evaluable tumor assessment.CR was defined as the disappearance of all lesions, pathological lymph node reduction in short axis to \<10 mm, and normalization of tumor marker levels of non-target lesions. PR was at least a 30% decrease in the sum of diameter of target lesions, taking as reference the baseline sum diameters. Progressive Disease (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 relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of 1 or more new lesions is also considered progression.

Time frame: Date of Complete Response (CR) or Partial Response (PR) to Date of Objective Disease Progression or Death Due to Any Cause (Up To 37 Months)

Part B: Pharmacokinetics (PK): Minimum Concentration (Cmin) of Ramucirumab

Part B: Pharmacokinetics (PK): Minimum Concentration (Cmin) of Ramucirumab

Time frame: Cycle 2 Day 1: Predose; Cycle 4 Day 1: Predose; Cycle 7 Day 1: Predose; Cycle 14 Day 1

Part B: Number of Participants With Anti-Ramucirumab Antibodies

Part B: Number of Participants With Anti-Ramucirumab Antibodies.

Time frame: Cycle 1 Predose through Follow-up (Up To 37 Months)

Part B: Best Change From Baseline on the Lung Cancer Symptom Scale (LCSS)

The LCSS consisted of 9 items: 6 items focused on lung cancer symptoms \[loss of appetite, fatigue, cough, dyspnea (shortness of breath), hemoptysis (blood in sputum), and pain\] and 3 global items (symptom distress, interference with activity level, and global quality of life). Participant responses to each item were measured using visual analogue scales (VAS) with 100-millimeter (mm) lines. A higher score for any item represented a higher level of symptoms/problems. The LCSS total score was defined as the mean of all 9 items. Average symptom burden index (ASBI) was calculated as the mean of the six symptom-specific questions from the LCSS. Potential scores range from 0 (for best outcome) to 100 (for worst outcome).

Time frame: Baseline, End of Study (Up To 37 Months)

Part B: Change From Baseline on the EuroQol 5-Dimension, 5-Level Questionnaire (EQ-5D-5L) Index Score

The EQ-5D-5L is a standardized instrument used to measure self-reported health status of the participants. It consists of 5 health dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). There are 5 response levels (no problems, slight problems, moderate problems, severe problems, and extreme problems/unable to), ranging from 1 to 5 (good to bad). Dimension responses were converted to an index score using UK weights. The index scores were anchored on full health (1.0) to dead (0) with negative values assigned to health states considered worse than death.

Time frame: Baseline, Cycle 10 (each cycle is 2 weeks)
