A Study to Assess Biomarkers Impact on Participants Response to Erlotinib Treatment for First-line Non-Small Cell Lung Cancer With Endothelial Growth Factor Receptor (EGFR) Activating Mutations
- Registration Number
- NCT01153984
- Lead Sponsor
- Hoffmann-La Roche
- Brief Summary
This open-label, single-arm, multi-center study will evaluate the progression-free survival in participants with histologically documented, advanced and/or metastatic chemotherapy naive, non-small cell lung cancer (NSCLC) with Epidermal Growth Factor Receptor (EGFR) positive mutations and receiving erlotinib treatment. The anticipated time on study treatment is until disease progression, unacceptable toxicity, withdrawal due to any reason or death.

Group Intervention Description Erlotinib Erlotinib Participants will receive 150 milligrams (mg) erlotinib orally daily until disease progression, unacceptable toxicity, withdrawal due to any reason or death.
- Primary Outcome Measures
Name Time Method Progression-Free Survival (PFS), as Assessed by Investigator Using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) Baseline up to approximately 4 years PFS was the time from inclusion in the study to the date of first documented PD or death from any cause, whichever occurred first. Participants without event were censored at the date of the last tumor assessment where non-progression was documented. If a participant received a second anti-cancer therapy without prior documentation of disease progression, the participant was censored at the date of last tumor assessment before starting new chemotherapy. Analysis was performed using Kaplan-Meier method. PD was defined as at least a 20% increase in the sum of LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions.
- Secondary Outcome Measures
Name Time Method Number of EGFR Positive Participants Classified Based on Type of EGFR Mutations Day 1 Participants with NSCLC have tumor associated with EGFR mutations. These mutations occur within EGFR Exons 18-21, which encodes a portion of the EGFR kinase domain.
Percentage of Participants With Complete Response (CR) And Partial Response (PR) as Assessed by the Investigator Using RECIST v1.1 Baseline up to approximately 4 years CR was defined as the disappearance of all target lesions, and PR was defined as at least a 30% decrease in the sum of the longest diameter compared to baseline.
Number of EGFR Positive Participants Classified Based on Smoking Status Day 1 Participants were asked: "Have you smoked at least 100 cigarettes in your entire life?" and "Do you now smoke cigarettes every day, some days, or not at all?" Responses were grouped into three categories: Current Smoker, Former Smoker, and Non-Smoker. Participants who reported smoking at least 100 cigarettes in their lifetime and who, at the time of survey, smoked either every day or some days were defined as 'Current smoker'. Participants who reported smoking at least 100 cigarettes in their lifetime and who, at the time of the survey, did not smoke at all were defined as 'Former smoker'. Participants who reported never having smoked 100 cigarettes were defined as 'Non-smoker'.
Percentage of Participants by Localization of PD, as Assessed by Investigator Using RECIST v1.1 Baseline up to approximately 4 years PD was assessed using RECIST v1.1. PD was defined as at least a 20% increase in the sum of LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions. Percentage of participants by localization of PD were reported. Localization included: Left lung inferior lobe; Para-aortic; Left lung upper lobe; Right lung inferior lobe; and Infracranial.
Percentage of Similar EGFR Mutations Between Matched Plasma and Tumor Tissue Samples Baseline up to approximately 4 years Time to Disease Progression, as Assessed by Investigator Using RECIST v1.1 Baseline up to approximately 4 years Time to disease progression was defined as the time from baseline evaluation to the first date PD was recorded. Participants without progression were censored at the date of last tumor assessment where non-progression was documented. PD was defined as at least a 20% increase in the sum of LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of 1 or more new lesions.
