Résumé : Tenidap is a novel anti-rheumatic drug that combines cytokine modulation with cyclo-oxygenase inhibition. This 24-week, multicentre, double-blind, randomized study compared the clinical efficacy, biochemical effects and safety of tenidap 120 mg/day (once daily) with diclofenac 150 mg/day (50 mg t.i.d.) in the treatment of 384 patients with active rheumatoid arthritis. After 24 weeks, improvement with tenidap was significantly greater than with diclofenac for all five primary efficacy parameters, two of the four secondary efficacy parameters and 11 of the 13 Arthritis Impact Measurement Scales assessments. The superior efficacy of tenidap was apparent after 4 weeks of treatment with further improvements observed by 24 weeks. The probability of discontinuation due to lack of efficacy was significantly greater in the diclofenac group. Tenidap but not diclofenac was associated with significant, rapid and sustained reductions in C-reactive protein and serum amyloid A levels and with a significant reduction in plasma interleukin-6. The nature and frequency of side-effects were similar in the two groups as was the discontinuation rate for treatment-related safety reasons. Tenidap was associated with an equal incidence of elevated transaminases, but a higher incidence of mild ( ≥ 500 mg/24 h < 1500 mg/24 h) non-progressive, proteinuria of proximal tubular origin compared with diclofenac. © 1995 British Society for Rheumatology.
