•Female or male adult (>=18 years) subjects at screening visit with a diagnosis
•of idiopathic (primary) MN confirmed by renal biopsy within 36 months prior to
•screening. A renal biopsy may be taken at any time during the run-in period to
•confirm the diagnosis of MN and facilitate subject eligibility, if the most
•recent biopsy was performed greater than 36 months prior to the screening visit.
•Anti-PLA2R antibody titer of >= 60 RU/mL at screening visit (based on the
•EuroImmun ELISA test)
•Urine protein >= 3.5 g/24h at run-in and baseline visits
•<=50% reduction in both anti-PLA2R level and 24h urine protein between first
•measurement at screening or run-in visit and baseline
•Estimated GFR (using the CKD-EPI formula) >= 30 mL/min per 1.73 m2 at
•screening visit
•Receiving stable dose at the maximum recommended dose according to local
•guidelines or maximum tolerated dose of ACEi and/or ARB and/or statins and/or
•diuretics for at least 8 weeks prior to Day 1
•Vaccination against Neisseria meningitidis, Streptococcus pneumoniae and
•Haemophilus influenzae (in accordance with local guidelines) at least 28 days
•prior to Day 1 and no longer than 5 years prior to Day 1

•Secondary causes of MN, e.g. systemic autoimmune diseases, solid or
•haematological malignancies, infections or chronic intake of drugs (e.g. gold
•salts, NSAIDs, penicillamines)
•Diagnostic renal biopsy showing evidence of crescent formation in glomeruli,
•suggestive of an alternative or additional diagnosis to primary idiopathic MN
•Previous treatment with B-cell depleting or B-cell modifying agents such as,
•but not limited to rituximab, belimumab, daratumomab or bortezomib
•Previous treatment with immunosuppressive agents such as cyclophosphamide,
•chlorambucil, mycophenolate mofetil (or equivalent), cyclosporine, tacrolimus
•or azathioprine within 90 days prior to Day 1. Low dose systemic corticosteroid
•therapy is permitted, though the subject should have been on stable dose
•equivalent to <=10 mg prednisolone for at least 90 days prior to Day 1
•Previous treatment with gemfibrozil or strong CYP2C8 inhibitors such as
•clopidogrel within 7 days prior to Day 1
•Presence or suspicion (based on judgment of the investigator) of active
•infection within 30 days prior to Day 1, or history of severe recurrent
•bacterial infections
