Brief Summary:
The aim of this trial is to optimize the treatment to induce remission for patients with non-life-threatening anti-neutrophil cytoplasmic antibody vasculitis (AAV). 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 or rituximab.

Condition or disease Intervention/treatment Phase
Vasculitis Drug: Placebo Drug: CCX168 Phase 2

Detailed Description:

The primary safety objective of this study is to evaluate the safety and tolerability of CCX168 in subjects with AAV on background cyclophosphamide or rituximab treatment.

The primary efficacy objective is to evaluate the efficacy of CCX168 based on the Birmingham Vasculitis Activity Score (BVAS) version 3.

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 vasculitis without the need for rescue corticosteroid measures and the effect of CCX168 on several disease parameters.

  • Male and postmenopausal or surgically sterile female subjects aged at least 18 years with new or relapsed AAV where treatment with cyclophosphamide or rituximab would be required
  • Positive indirect immunofluorescence (IIF) test for P-ANCA or C-ANCA, or positive ELISA test for anti-proteinase-3 (PR3) or anti-myeloperoxidase (MPO) at screening
  • Estimated glomerular filtration rate (eGFR) ≥ 20mL/min

Key Exclusion Criteria:

  • Severe disease as determined by rapidly progressive glomerulonephritis, alveolar hemorrhage, hemoptysis, rapid-onset mononeuritis multiplex or central nervous system involvement
  • Any other multi-system autoimmune disease
  • Medical history of coagulopathy or bleeding disorder
  • Received cyclophosphamide within 12 weeks of screening; if on azathioprine, mycophenolate mofetil or methotrexate at the time of screening, these drugs must be withdrawn prior to receiving the cyclophosphamide or rituximab dose on Day 1
  • Received high-dose intravenous corticosteroids within 4 weeks of screening
  • On an oral dose of a corticosteroid of more than 10mg prednisone-equivalent at the time of screening
  • Received rituximab or other B-cell antibody within 52 weeks of screening or 26 weeks provided B cell reconstitution has occurred; received anti-TNF treatment, abatacept, alemtuzumab, IVIg or plasma exchange within 12 weeks of screening
