Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Phase II Efficacy and Safety Study of IFX-1 in Add-On to Standard of Care in Granulomatosis With Polyangiitis (GPA) and Microscopic Polyangiitis (MPA)

Brief Summary

      The purpose of this study is to investigate the safety and tolerability of two dose regimens
      of IFX-1 as add-on to standard of care (SOC) in subjects with GPA and MPA compared with

Detailed Description

      Granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) are related
      systemic v anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), a
      potentially life-threatening disease.

      GPA is a necrotizing vasculitis predominantly involving small- to medium-sized vessels (e.g.,
      capillaries, venules, arterioles, arteries, and veins). MPA is a necrotizing vasculitis that
      primarily affects capillaries, venules, or arterioles, most commonly manifesting as
      necrotizing glomerulonephritis and/or pulmonary capillaritis. MPA.

      Primed neutrophils are activated by ANCA and generate C5a that engages C5a receptors on
      neutrophils. Therefore, patients with ANCA-related disease have elevated plasma and urine
      levels of C5a in active disease and not in remission.

      IFX-1 is a monoclonal antibody specifically binding to the soluble human complement split
      product C5a and the resulting nearly complete blockade of C5a-induced biological effects may
      be effective in the treatment of subjects with AAV.

Eligibility Criteria

        Inclusion Criteria:

          1. Male or female, ≥18 years of age.

          2. Diagnosis of GPA or MPA according to the definitions of the Chapel Hill Consensus

          3. Have at least one "major" item, or at least three other items, or at least two renal
             items on the Birmingham Vasculitis Activity Score (BVAS) Version 3.0.

          4. New or relapsed GPA or MPA that require treatment with CYC or RTX plus GCs.

        Exclusion Criteria:

          1. Any other multisystem autoimmune disease

          2. Requires mechanical ventilation because of alveolar hemorrhage at Screening.

          3. Human immunodeficiency virus, hepatitis B, or hepatitis C viral screening test showing
             evidence of active or chronic viral infection at Screening or a documented history of
             the human immunodeficiency virus, hepatitis B, or hepatitis C.

          4. Received CYC or RTX 12 weeks before Screening; if on azathioprine (AZA), methotrexate
             (MTX), mycophenolate mofetil (MMF), or mycophenolate sodium (MPS) at the time of
             Screening, these drugs must be withdrawn prior to receiving CYC or RTX.

          5. Received more than 3 g cumulative high dose intravenous GCs within 4 weeks before

          6. On an oral dose of a GC of more than 10 mg prednisone equivalent at Screening or for
             more than 6 weeks before Screening.

          7. Received a CD20 inhibitor, anti-tumor necrosis factor treatment, abatacept,
             alemtuzumab, any other experimental or biological therapy, intravenous immunoglobulin
             or plasma exchange, antithymocyte globulin, or required dialysis within 12 weeks
             before Screening.

          8. Received a live vaccination within 4 weeks before Screening or planned between
             Screening and Week 24.

          9. Female subjects of childbearing potential unwilling or unable to use a highly
             effective method of contraception (pearl index <1%) such as complete sexual
             abstinence, combined oral contraceptive, vaginal hormone ring, transdermal
             contraceptive patch, contraceptive implant, or depot contraceptive injection in
             combination with a second method of contraception such as condom, cervical cap, or
             diaphragm with spermicide during the study and for at least 4 weeks after last
             administration of IFX-1 (timeframes for SOC have to be considered as described in the
             respective Prescribing Information).
