             patients on a maximum recommended or maximum tolerated dose of an angiotensin
             converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)

          -  UPCR ≥ 100 mg/mmol (equivalent to ≥ 1 g/24h total urinary protein excretion)

          -  Prior to entry, all patients must have been on supportive care including a maximally
             tolerated dose of ACEi or ARB for at least 30 days.

        Inclusion Criteria for Cohort B:

          -  No histological/laboratory/clinical signs of allorejection

          -  If applicable, induction treatment after allotransplantation needs to be completed >30
             days before inclusion.

          -  Transplantation of a kidney allograft >90 days before inclusion

          -  Patients need to be on a stable dose of immunosuppressive regimen prior to inclusion.
             Any approved treatments are allowed for this purpose.

        Exclusion Criteria for Cohort A and B:

          -  Use of other investigational drugs at the time of enrollment, or within 5 half-lives
