Study design details

• Main study objective:
  To determine in Chinese patients in real-world setting with EGFR mutation-positive non-small cell lung cancer (NSCLC) the time on treatment (TOT) of afatinib as first-line treatment followed by 3rd generation EGFR-TKI in the event that T790M resistance mutation was developed
• Outcomes:
  TOT with afatinib as first-line treatment followed by 3rd generation EGFR-TKI in the event of the T790M resistance mutation is developed in patients with EGFR mutation-positive NSCLC. This will be assessed as the time from the start of afatinib as first-line treatment until the last dose of 3rd generation EGFR-TKI. 1.TOT with afatinib as first-line treatment followed by investigator’s choice treatment in event of the T790M negative status in real-world setting2.OS from the start of afatinib until the date of death 3.PFS as judged by an investigator with afatinib in first-line treatment 4.ORR OR is defined as best overall response of CR and PR according to RECIST 1.1 with afatinib in first-line tre...
• Data analysis plan:
  TOT will be analysed using Kaplan-Meier method, and the median TOT along with two-sided 90% confidence interval (CI) will be calculated. PFS and OS will be analysed similarly. ORR, DCR, and acquired resistance mutation type, and AEs will be summarised descriptively by frequency and proportions.
