Phase II study of docetaxel and gefitinib as second-line therapy in gemcitabine pretreated patients with advanced pancreatic cancer.

ABSTRACT

BACKGROUND: There is no standard second-line therapy for advanced pancreatic cancer (APC). We evaluated the epidermal growth factor receptor (EGFR) inhibitor gefitinib and docetaxel in a phase II study following gemcitabine failure. METHODS: EGFR overexpression was not required. The initial docetaxel dose was 75 mg/m(2) on day 1 every 21 days. Due to febrile neutropenia in 8 of the first 18 patients, the dose was reduced to 60 mg/m(2). Gefitinib, 250 mg/day orally, was given continuously. RESULTS: Forty-one patients received treatment and were evaluable. Febrile neutropenia was seen in 11 patients (27%), with most events occurring at the docetaxel dose of 75 mg/m(2) (8 of 18 patients). Common treatment-related grade 3/4 toxicities were fatigue (7%), nausea (7%), diarrhea (5%) and vomiting (2%). There was 1 partial response and stable disease in 19 patients. Time to progression was 1.8 months and median survival was 4.5 months (95% CI 2.9-5.7). CONCLUSION: The tolerability and feasibility of second-line therapy for APC was demonstrated. The combination of gefitinib and docetaxel showed evidence of limited efficacy.
