Reduction of Acute-Phase Proteins with Tenidap Sodium, a Cytokine-Modulating Anti-Rheumatic Drug

Four independent studies have investigated and compared the effects of tenidap sodium, naproxen and placebo on CRP in patients with active RA. One of these studies also investigated the effects of tenidap and naproxen on serum amyloid A (SAA) concentrations and ESR. The duration of the four studies ranged between 2 weeks and 24 weeks, and depending on the study, tenidap sodium was administered orally in doses of 40-120 mg/day and naproxen in doses of 1000 mg/day. In all four studies serum CRP concentrations in tenidap-treated patients had decreased significantly from baseline at the time of final assessment. The decrease in CRP concentration in tenidap-treated patients was observed as early as 1 week after initiation of therapy and was sustained for up to 6 months, the last assessment timepoint
