Aims:  The efficacy of erlotinib (Tarceva, Roche Products, Dee Why, Australia) has been demonstrated in patients with advanced non-small-cell lung cancer (NSCLC). Tarceva lung cancer survival treatment (TRUST) is an open-label, single-arm, phase IV global trial which investigated erlotinib in advanced NSCLC patients who had failed prior therapy or were unsuitable for chemo/radiotherapy. The aim of this analysis was to report the safety and efficacy of erlotinib in the Australian patient subpopulation.

Methods:  Patients with stage IIIB/IV NSCLC progressing after standard systemic chemotherapy or unsuitable to receive chemo/radiotherapy were eligible for the study. The patients were treated with erlotinib at 150 mg/day orally, until disease progression or unacceptable toxicity.

Results:  In Australia, 460 patients were recruited. Erlotinib was given as first-line (16%), second-line (49%) or third-line (35%) treatment. In the intent-to-treat population (N = 460), the median progression-free survival was 2.7 months (95% CI 2.3–3.4), 1-year survival was 35% (95% CI 30–39%) and median overall survival was 6.9 months (95% CI 5.7–8.0). Tumor response rates were available for 363 patients, with a disease control rate of 58%. Of the 460 patients included in the safety analysis, 24% had one or more erlotinib-related adverse event (AE). Rash was reported in 77% of patients, most commonly grade 1/2 (63%). Treatment-related serious AE were reported in 7% of patients; most commonly diarrhea (2%). Dose modifications were required in 18% of patients.

Conclusions:  Outcomes for Australian patients confirmed the efficacy and tolerability of erlotinib for the treatment of advanced NSCLC in routine clinical practice.
