Abstract

Background/Aims: To test the role of chemokine C-C motif ligand 2 (CCL2) in the pathogenesis of lupus nephritis (LN), we evaluated the effects of CCL2 inhibition by bindarit therapy in patients with systemic lupus and active renal disease. Methods: In this proof-of-concept, prospective, randomized, double-blind clinical study, 22 subjects with acute LN were assigned on a 1:1 ratio to 24-week treatment with bindarit (1,200 mg/day) or matching placebo. All subjects were on the same standardized steroid background therapy. Urinary CCL2, urinary albumin excretion (UAE), estimated glomerular filtration rate, time to remission and time to relapse of LN were compared between groups. Results: Urinary CCL2 significantly decreased during bindarit therapy (p = 0.008 vs. baseline) with a reduction that approximated 50% at study end. CCL2 reduction was paralleled by a persistent reduction in UAE that averaged 80% vs. baseline and approximated 90% at study end. Renal function recovery was similar and no difference was found in terms of time to remission and time to relapse of LN between treatment arms. Treatment was safe and well tolerated in all patients. Conclusion: In lupus subjects with active nephritis, bindarit significantly reduced albuminuria and urinary CCL2 levels. This study provides the background for longer trials to test renoprotective effect of CCL2 inhibition in LN.
