Overview
Brief Summary
The primary purpose of this study is to evaluate the efficacy of the study drug known as LY2875358, administered alone or in combination with a second drug named Erlotinib, in participants affected by a defined type of lung cancer (MET biomarker diagnostic positive Non-Small-Cell Lung Cancer) that experienced a disease progression during the most recent treatment with Erlotinib.

Outcomes
Primary Outcomes
Percentage of Participants Achieving Complete Response (CR) or Partial Response (PR) (Overall Response Rate [ORR])
Time Frame: Baseline to Objective Disease Progression or Start of New Anticancer Therapy (Up to 15 Months)
ORR is confirmed best overall tumor response of CR or PR. According to RECIST v1.1, CR was defined as the disappearance of all target and non-target lesions; 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. Percentage of participants was calculated as: (total number of participants with CR or PR from start of the treatment until disease progression or recurrence)/total number of participants treated) \* 100.
Secondary Outcomes
- Progression Free Survival (PFS)(Baseline to Objective Disease Progression or Death (Up to 24 Months))
- Time to Progressive Disease(Baseline to Objective Disease Progression (Up to 24 Months))
- Change in Tumor Size (CTS)(Baseline to Measurement with Smallest Tumor Size (Up to 24 Months))
- Secondary: Percentage of Participants Who Achieved Best Overall Disease Response of CR, PR or Stable Disease (SD) [Disease Control Rate (DCR)](Baseline to Objective Disease Progression or Participant Stops Study (Up to 24 Months))
- Duration of Response (DoR)(Date of CR or PR to Date of Objective Disease Progression or Death Due to Any Cause (Up to 24 Months))
- Overall Survival (OS)(Baseline to Death Due to Any Cause (Up to 24 Months))
- Change From Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires C30 (QLQ-C30)(Baseline, Objective Disease Progression or Participants Stops Study (Up to 24 Months))
- Change From Baseline in EORTC Quality of Life Questionnaires Lung Cancer 13 (QLQ-LC13)(Baseline, Objective Disease Progression or Participants Stops Study (Up to 24 Months))
- Change From Baseline in EuroQol 5-Dimensional Scale (EQ-5D)(Baseline, Objective Disease Progression or Participants Stops Study (Up to 24 Months))
- Pharmacokinetics (PK): Area Under the Concentration (AUC) of Emibetuzumab(Cycle1 Day 1 (C1 D1): Pre-dose and End of infusion; C1 D8: Pre-dose; C1 D15, C2 D1, C2 D15, C3 D1, C3 D15, C4 D1, C4 D15: Pre-dose and End of Infusion)
- Number of Participants With Anti-Emibetuzumab Antibody (ADA) Response(Baseline through 30-Day Follow-Up (Up to 24 Months))
