Summary:

      This is an open-label Phase 2a clinical study designed to evaluate the safety and efficacy of
      AVB-S6-500 in patients with IgA Nephropathy (IgAN). Approximately 24 patients will be
      enrolled. Several dose levels of AVB-S6-500 may be evaluated.
    

Eligibility criteria:

          -  Proteinuria ≥ 1g to 3g/24hr

          -  Stable estimated glomerular filtration rate (eGFR) for at least 3 months prior to
             screening and ≥ 45 mL/min per 1.73 m2 using the Chronic Kidney Disease Epidemiology
             Collaboration formula

          -  Systolic BP lesser than or equal to 150 mmHg and diastolic BP lesser than or equal to

             the study are allowed on study (patients who are not on ACEi/ARB due to inability to
             tolerate these therapies are also allowed)

          -  If a sexually-active patient, must agree to use a reliable method of birth control
             from at least 4 weeks prior to first dose of study drug, during the study and for 1

             of the first dose of study drug

          -  Rapidly progressing nephropathy defined as falling GFR (≥ 15%) over past 3 mos

          -  Clinical or biological evidence of diabetes mellitus, systemic lupus erythematosus,
             IgA vasculitis (Henoch-Schonlein purpura), secondary IgAN, or other renal disease

          -  Hemoglobin < 9.0 g/dL

          -  History or clinical evidence of cirrhosis, or liver disease with serum alanine
             aminotransferase (ALT) or aspartate aminotransferase (AST) > 3x upper limit of normal

          -  Organ transplant recipient (including bone marrow) or a planned transplant during the
             study

          -  Have a diagnosis of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C
             infection, or positive serology at screening

          -  Recent active infection requiring hospitalization or i.v. treatment within 30 days
             prior to the first dose of study drug

          -  Received transfusion, plasmapheresis or plasma exchange, IV immunoglobulin (IVIg)
             within 90 days prior to screening
