Gastroduodenal safety and tolerability of lumiracoxib compared with Ibuprofen and celecoxib in patients with osteoarthritis.

OBJECTIVE: To compare the incidence of gastroduodenal ulcers in patients with osteoarthritis (OA) treated with therapeutic doses of the novel COX-2 selective inhibitor, lumiracoxib (COX189, Prexige), and the standard nonsteroidal antiinflammatory drug (NSAID) ibuprofen. The COX-2 selective inhibitor celecoxib was included as an active control. METHODS: In this randomized, multicenter, double-blind, parallel-group study, eligible patients were randomized to receive lumiracoxib 200 mg (n = 264) or 400 mg (n = 260) once daily (qd), ibuprofen 800 mg (n = 260) 3 times daily (tid), or celecoxib 200 mg qd (n = 258) for 13 weeks. The incidence of gastroduodenal ulcers and erosions was determined by endoscopy prior to randomization, and after 4 weeks and 13 weeks of treatment (end of study). Frequencies of adverse events were also recorded. RESULTS: The cumulative incidence of gastroduodenal ulcers >/= 3 mm in diameter was significantly lower in the lumiracoxib groups (200 mg: 4.3%; 400 mg: 4.0%) than in the ibuprofen group (15.7%; p < 0.001) and similar to the celecoxib group (3.2%). In the ibuprofen group, a significantly greater number of patients (6.0%) had > 10 gastroduodenal erosions compared with lumiracoxib 200 mg (1.2%; p < 0.01), lumiracoxib 400 mg (1.6%; p < 0.05), and celecoxib (2.4%; p < 0.05). A greater number of patients in the ibuprofen group discontinued treatment due to an adverse event compared with both lumiracoxib groups and the celecoxib group. CONCLUSION: In patients with OA, lumiracoxib 200 mg or 400 mg qd was associated with a significantly lower risk of gastroduodenal ulceration than ibuprofen 800 mg tid, and was similar to celecoxib 200 mg qd.[1]
