Erlotinib in routine clinical practice for first-line maintenance therapy in patients with advanced non-small cell lung cancer (NSCLC)

Abstract

Purpose

The controlled phase III trial SATURN demonstrated that maintenance therapy with erlotinib after the first-line platinum-based chemotherapy prolonged progression-free survival (PFS) and overall survival (OS) of non-small cell lung cancer (NSCLC) patients with advanced, non-progressive disease. We conducted the non-interventional study SATURN NIS to investigate the effectiveness and tolerability of erlotinib maintenance in daily clinical practice.

Methods

This single-arm NIS screened 290 patients with locally advanced or metastatic NSCLC (stage IIIB or IV) and stable disease after standard platinum-based first-line chemotherapy in 95 institutions across Germany. Erlotinib was dosed and administered corresponding to the terms of the marketing authorization at the time of recruitment. The main effectiveness endpoint was subjects' OS at 1 year. Subgroup analyses of survival estimates of OS and PFS were performed.

Results

272 patients were eligible for analysis (median age 66 years, 37.1% females, 99.6% Caucasian, median ECOG performance status 1, 61.8% adenocarcinoma, 96.3% of patients with stable disease). Maintenance therapy with erlotinib resulted in median OS comparable to that of the SATURN phase III trial 10.4 months [95% CI: (8.8; 12.5) vs. 11.9 months]. The 1-year survival rate was 45.6% [95% CI: (37.5%; 53.6%)]. No new safety signals were observed. As expected, patients with epidermal growth factor receptor (EGFR) mutations derived a greater benefit concerning OS and PFS than EGFR–wild-type patients. Moreover, a significant association of OS and PFS and the smoking status was observed.

Conclusions

The results of this non-interventional study support the current clinical practice of erlotinib switch maintenance in EGFR-mutation-positive patients.
