title: Modified-release prednisone: in patients with rheumatoid arthritis.
abstract: Prednisone is a well-established treatment option in rheumatoid arthritis. Low-dose glucocorticoid therapy alleviates disease signs and symptoms, is better tolerated than high-dose therapy, and its addition to disease-modifying anti-rheumatic drugs (DMARDs) inhibits radiographic disease progression. A low-dose, modified-release (MR) formulation of prednisone, administered in the evening, was developed to counter the circadian rise in pro-inflammatory cytokine levels that contributes to disease activity. In a 12-week, randomized trial (CAPRA-2) in adult patients with rheumatoid arthritis who were receiving stable DMARD therapy, the addition of MR prednisone reduced disease signs and symptoms by ≥20 % according to the American College of Rheumatology criteria (in 48 % of patients vs. 29 % with placebo; p < 0.002 [primary endpoint]). In another 12-week trial (CAPRA-1), addition of evening MR prednisone to stable DMARD therapy reduced the mean duration of morning stiffness to a greater extent than addition of morning immediate-release (IR) prednisone (22.7 vs. 0.4 %; p = 0.045 [primary endpoint]). The improvement in morning stiffness with MR prednisone was maintained for 9-12 months during the open-label extension of CAPRA-1. These findings were supported by data from observational studies in various adult populations with rheumatoid arthritis. Treatment with evening MR prednisone for up to 12 months was generally well tolerated, with an overall similar tolerability profile compared with evening placebo or morning IR prednisone, and no new safety concerns. MR prednisone was estimated to be cost effective relative to IR prednisone in patients with rheumatoid arthritis in a UK pharmacoeconomic model.
