  Purpose

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.

Primary Outcome Measures:
  • Safety of CCX168 in subjects with AARV [ Time Frame: 169 days ] [ Designated as safety issue: Yes ]
    Safety assessments include adverse events, physical examination abnormalities, vital signs and clinical laboratory tests (including blood chemistry, hematology and urinalysis).


Secondary Outcome Measures:
  • Systemic corticosteroid use [ Time Frame: 169 days ] [ Designated as safety issue: No ]
    Systemic corticosteroid use based on total oral corticosteroid dose and duration of oral corticosteroid use

Detailed Description:

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.

  Eligibility

Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Key Inclusion Criteria:

  • Clinical diagnosis of Wegener's granulomatosis, microscopic polyangiitis or renal limited vasculitis
  • Male and postmenopausal or surgically sterile female subjects aged 18-80 years with new or relapsed AARV where treatment with cyclophosphamide 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
  • Proven to have renal vasculitis based on renal biopsy or hematuria and proteinuria compatible with nephritis
  • Estimated glomerular filtration rate ≥ 25mL/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 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
