Abstract: OBJECTIVE: /st> C-C chemokine receptor type 5 (CCR5), a chemokine receptor expressed on T cells and macrophages, and its ligands are found in inflamed synovial tissue (ST) of patients with rheumatoid arthritis (RA). The rationale for testing CCR5 blockade in patients with RA was supported by the effects of a CCR5 antagonist in collagen-induced arthritis in rhesus monkeys. The effects of CCR5 blockade in patients with active RA were explored. METHODS: /st> In this phase Ib randomised, placebo-controlled trial, treatment with an oral CCR5 inhibitor (SCH351125) in patients with active RA was evaluated. Clinical efficacy was assessed using European League Against Rheumatism and American College of Rheumatology response criteria. ST biopsies were taken before and after 28 days of treatment, and analysed for CCR5+ cells. In a subset of patients, MRIs of an inflamed joint were obtained before and after treatment. RESULTS: /st> In all, 32 patients were included; 20 received SCH351125 and 12 placebo. Three patients who received SCH351125 did not complete the study due to adverse events; none of these were serious. No improvement was observed in the active treatment group compared to placebo. Results were consistent for clinical evaluation, ST analysis and MRI. CONCLUSION: /st> This proof of concept study does not support the use of CCR5 blockade as a therapeutic strategy in patients with active RA.
