Abstract
BackgroundIncreased expression of cyclooxygenase-2 (COX-2) is common in non-small cell lung cancer (NSCLC) and has been associated with poor prognosis. Experimental and clinical phase II trials have indicated that the addition of the COX-2 inhibitor celecoxib to palliative chemotherapy might increase survival time in patients with advanced NSCLC. MethodsWe performed a double-blind, placebo-controlled multicentre phase III trial at 13 centres in Sweden. Three hundred and nineteen patients with advanced NSCLC stage IIIB–IV and performance status 0–2 were randomised to receive celecoxib 400mg b.i.d. or placebo in addition to palliative chemotherapy. The primary objective was to compare overall survival. Other end-points were quality of life, progression-free survival, toxicity, cardiovascular events and biological markers.The trial is registered with ClinicalTrials.gov, No. NCT00300729. FindingsThree hundred and sixteen patients were included in the analysis, 158 in each treatment group. Median survival time was 8.5months. There was no survival difference between the treatment arms. Small but not statistically significant differences in global quality of life and pain were seen favouring the celecoxib group. No increased incidence of cardiovascular events was observed in the celecoxib group. InterpretationThis study failed to demonstrate a survival benefit of the addition of celecoxib to palliative chemotherapy.
