OBJECTIVE: To compare cardiovascular (CV) and other safety and efficacy parameters of etoricoxib 60 and 90 mg, and diclofenac 150 mg. METHODS: This double-blind study randomized OA patients to etoricoxib 90 mg, then to 60 mg once daily vs diclofenac 75 mg twice daily; RA patients were randomized to etoricoxib 90 mg once daily or diclofenac 75 mg twice daily. The primary endpoint was non-inferiority of etoricoxib vs diclofenac for thrombotic CV events (95% CI upper bound of hazard ratio <1.30). Other safety and efficacy parameters were evaluated in cohorts of patients based on etoricoxib dose and disease. RESULTS:A total of 23 504 patients were randomized with mean treatment duration from 19.4 to 20.8 months. The thrombotic CV risk hazard ratio (HR) (etoricoxib to diclofenac) was 0.96 (95% CI 0.81, 1.15), consistent with non-inferiority of etoricoxib to diclofenac. The cumulative gastrointestinal (GI)/liver adverse events (AEs) discontinuation rate was significantly lower for etoricoxib than diclofenac in each patient cohort; HR (95% CI) of 0.46 (0.39, 0.54), 0.52 (0.42, 0.63) and 0.49 (0.39, 0.62) for the 60 mg OA, 90 mg OA and RA cohorts. The maximum average change in systolic blood pressure (BP) with etoricoxib was 3.4-3.6 mmHg (diastolic BP: 1.0-1.5 mmHg), while diclofenac produced a maximum average change of 0.9-1.9 mmHg (diastolic BP: 0.0-0.5 mmHg). Both agents resulted in similar efficacy regardless of etoricoxib dose. CONCLUSION: Long-term etoricoxib use is associated with a risk of thrombotic CV events comparable with that of diclofenac. Compared with diclofenac, etoricoxib demonstrated a greater risk of renovascular AEs, but a more favourable GI/liver tolerability profile.
