A Study to Evaluate the Safety and Efficacy of CCX168 in Subjects With ANCA-Associated Renal Vasculitis
The aim of this trial is to optimize the treatment to induce remission for patients with non-life-threatening anti-neutrophil cytoplasmic antibody renal vasculitis (AARV) with mild-to-moderate renal involvement. The intent is to reduce the toxicity of induction therapy by reducing the overall exposure to or eliminating entirely the use of systemic corticosteroids during the induction period with an inhibitor of the complement C5a receptor plus cyclophosphamide.

The primary objective of this study is to evaluate the safety and tolerability of CCX168 in subjects with AARV on background of cyclophosphamide treatment.
The secondary objectives of this study include assessment of the feasibility of reducing or eliminating the use of corticosteroids in the treatment of subjects with ANCA-associated renal vasculitis without the need for rescue corticosteroid measures and the effect of CCX168 on several disease parameters.
