LUNG CANCER : Making the case for EGFR TKI sequencing in EGFR mutation-positive NSCLC: a GioTag study US patient analysis
Abstract
Aim: To assess time-to-treatment failure (TTF) in US patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC) who received sequential afatinib–osimertinib treatment in the global, observational GioTag study. Patients & methods: Patients had EGFR T790M mutation-positive disease after first-line afatinib and subsequently received osimertinib. The primary outcome was TTF. Results: In 129 patients at US centers, median TTF was 28.4 months (90% CI: 27.0–34.1). Median overall survival was 47.6 months (90% CI: 35.5–51.5). Conclusion: Sequential afatinib–osimertinib in this US-treated population was associated with long median TTF and represents an effective, evidence-based treatment option for US patients with EGFR mutation-positive NSCLC not presenting with active brain metastases or de novo T790M
