Objectives: Overview of three dose-response studies demonstrating the efficacy of lumiracoxib, a novel COX-2 selective inhibitor, for chronic pain associated with osteoarthritis (OA), or rheumatoid arthritis (RA) and acute pain following dental extraction. Methods: OA and RA: 4-week, randomized, placebo- and active-controlled studies of similar design. Patients (OA, n = 583; RA, n = 571) received lumiracoxib 50 mg, 100 mg or 200 mg twice daily (bid), lumiracoxib 400 mg once daily (od), diclofenac 75 mg bid or placebo. Dental: 12-h, single-center, randomized, placebo- and active-controlled study. Patients (n = 202) received single oral doses of lumiracoxib 100 mg or 400 mg, ibuprofen 400 mg or placebo. Main outcome measures: OA: pain intensity (PI) in the target joint (visual analogue scale [VAS]) and WOMAC score at Week 4; RA: overall PI (VAS) and ACR20 response at Week 4; Dental: difference (PID, categorical and VAS) score over 12h post dose, time to onset of analgesia. Results: Throughout the OA study, all lumiracoxib doses provided superior reductions in PI versus placebo and at Week 4, all lumiracoxib doses provided efficacy similar to each other and to diclofenac. In the RA study, lumiracoxib 100 mg bid, 200 mg bid and 400 mg od were significantly better than placebo in PI at Weeks 1 and 2 (all p < 0.05) but demonstrated borderline significance at Week 4 (lumiracoxib 400 mg od, p = 0.06). In pain following dental surgery, PID scores for both lumiracoxib doses were superior to placebo from 1.5h onwards and always comparable, or superior, to ibuprofen. Lumiracoxib 400 mg had the fastest onset of analgesia, measured as median time to confirmed first perceptible pain relief using the two-stopwatch method (37.4 min, superiority versus placebo, p < 0.001). Lumiracoxib was well tolerated in all studies. Conclusions: These studies provide initial evidence that lumiracoxib is an effective, well-tolerated agent for the treatment of chronic and acute pain.
