Outcomes
Primary Outcomes
Number of Differentially Expressed Genes Associated With Clinical Benefit
Time Frame: Baseline until disease progression, unacceptable toxicity or death, evaluated up to 4 years
Affymetrix gene expression profiles were primarily analyzed to identify differentially expressed genes between the participants who derived clinical benefit status and those who did not. Analysis was performed using a multivariate linear model (with clinical benefit status, histology, ethnicity, sex, RNA integrity number (RIN), smoking status and stage as predictors), and a False Discovery Rate criteria of below 0.3 as cut-off. Clinical benefit is defined in the Outcome Measure 5.
Number of KRAS Mutation Participants Who Achieved Clinical Benefit
Time Frame: Baseline until disease progression, unacceptable toxicity or death, evaluated up to 4 years
Affymetrix gene expression profiles were primarily analyzed to identify differentially expressed genes between the participants who derived clinical benefit status and those who did not. Analysis was performed using a multivariate linear model (with clinical benefit status, histology, ethnicity, sex, RNA integrity number (RIN), smoking status and stage as predictors), and a False Discovery Rate criteria of below 0.3 as cut-off. Number of participants with KRAS gene mutation and who achieved clinical benefit status was reported. Clinical benefit is defined in the Outcome Measure 5.
Number of Epidermal Growth Factor Receptor (EGFR) Mutation Participants Who Achieved Clinical Benefit
Time Frame: Baseline until disease progression, unacceptable toxicity or death, evaluated up to 4 years
Affymetrix gene expression profiles were primarily analyzed to identify differentially expressed genes between the participants who derived clinical benefit status and those who did not. Analysis was performed using a multivariate linear model (with clinical benefit status, histology, ethnicity, sex, RNA integrity number (RIN), smoking status and stage as predictors), and a False Discovery Rate criteria of below 0.3 as cut-off. Number of participants with EGFR mutation (L858R/ exon 19 deletion) and who achieved clinical benefit status was reported. Clinical benefit is defined in the Outcome Measure 5.
Secondary Outcomes
- Percentage of Participants With Clinical Benefit (CR, PR, or Stable Disease [SD] for at Least 12 Weeks After Study Entry) Using RECIST(Baseline until disease progression, unacceptable toxicity or death, evaluated up to 4 years)
- Percentage of Participants With Overall Response of Complete Response (CR) or Partial Response (PR) Using Response Evaluation Criteria in Solid Tumors (RECIST)(Baseline until disease progression, unacceptable toxicity or death, evaluated up to 4 years)
