BACKGROUND: Cyclooxygenase-2 selective inhibitors were developed in order to reduce the incidence of life-threatening gastrointestinal ulcer complications compared with non-selective non-steroidal anti-inflammatory drugs. Previous outcomes studies have, variously, lacked power to investigate this endpoint, focused on broader outcomes, or been too small to quantify the influence of aspirin. AIM: To evaluate lumiracoxib, a novel cyclooxygenase-2 selective inhibitor, vs. non-selective non-steroidal anti-inflammatory drugs in an outcomes study of considerably increased size. This paper describes the study's methodology. METHODS AND PATIENTS: The Therapeutic Arthritis Research and Gastrointestinal Event Trial was a randomized, double-blind, 52-week study of lumiracoxib 400 mg once daily (two to four times the recommended dose for osteoarthritis) versus naproxen 500 mg twice daily or ibuprofen 800 mg three-times daily in patients with osteoarthritis. Randomization was stratified for low-dose aspirin use and age (< or = 64, 65-74, > or= 75 years). The study was powered to investigate upper gastrointestinal ulcer complications (primary endpoint) in patients not taking aspirin and in the overall study population; other endpoints included cardiovascular, renal and hepatic measures. CONCLUSIONS: Therapeutic Arthritis Research and Gastrointestinal Event Trial was designed to provide definitive answers concerning the gastrointestinal safety of lumiracoxib, addressing the controversial issues arising from outcomes studies with other cyclooxygenase-2 selective inhibitors.
