- Abstract
- Introduction: Erlotinib is an epidermal growth factor receptor tyrosine kinase inhibitor that significantly increases survival for patients with previously treated advanced non-small cell lung cancer. Epidermal growth factor receptor tyrosine kinase inhibitors have been reported to be particularly effective in Asian patients and may have a distinct safety profile in this population compared with non-Asian patients. We report safety and efficacy data from a subpopulation of East/South-East (E/SE) Asian patients enrolled in a global, open-label, phase IV trial of erlotinib (Tarceva Lung Cancer Survival Treatment study). Methods: Patients who had previously failed on chemotherapy or radiotherapy, or were unsuitable for these treatments, were treated with oral erlotinib (150 mg/d) until disease progression or unacceptable toxicity. Results: Best response data were available for 1118 E/SE Asian and 4276 non-E/SE Asian patients. The overall response rates were 27% versus 10%, respectively (p < 0.0001). The disease control rates were 78% versus 66%, respectively (p < 0.0001). Survival data were available for 1242 E/SE Asian and 5338 non-E/SE Asian patients. The median progression-free survival times were 5.78 months versus 2.92 months, respectively (hazard ratio = 0.66, p < 0.0001). The median overall survival times were 14.7 months versus 6.8 months, respectively (hazard ratio = 0.57, p < 0.0001). One-year survival rates were 58.3% and 32.7%, respectively. Safety data were available for 1242 E/SE Asian patients. Seventeen percent of these patients experienced one or more erlotinib-related adverse event (AE) (other than the most frequently occurring AEs prespecified in the protocol) and 2% experienced an erlotinib-related serious AE. Dose reductions were reported for 171 (14%) patients. Conclusion: Erlotinib is an effective and well-tolerated treatment for Asian patients with advanced non-small cell lung cancer.
