Participant gender:

Summary
Type I membranoproliferative glomerulonephritis (MPGN) is a relatively uncommon glomerular disease, constituting 1.8% of renal biopsies performed in Rochester, minnesota, United States of America, at the Mayo Clinic, between 1993 and 2008. The prognosis of idiopathic Type I MPGN is relatively poor. Recently, Irish series, slightly more than 50% of patients developed end stage renal disease after a mean follow up of 14 years . The disease may recur after renal transplantation . High-dose glucocorticoids have been used to treat this disease in children but there is no established treatment in adults.

Criteria
Inclusion Criteria:

1. MPGN either native/renal transplant kidneys with biopsy last 3 years.

2. Age > 18 years.

3. Urinary protein to creatinine ratio > 1.0 in a 24-hour urine collection, despite
angiotensin converting enzyme inhibitor/angiotensin receptor blocker treatment.

4. Patients need to be treated with an ACEI and/or ARB, for at least 3 months prior to
enrollment with the systolic blood pressure < 140 mm Hg for at least 75% of readings.

5. Women must be post-menopausal, surgically sterile or practicing a medically approved
method of contraception.

6. Patients intolerant of ACE inhibitors/ARBs may enter the study without being treated
with these agents.

7. Estimated glomerular filtration rate ≥ 25 ml/min per 1.73m^2 in the presence of ACE
inhibitor/ARB therapy. The GFR will be estimated using the 4 variable Modification of
Diet in Renal Disease (MDRD) equation/National Kidney Foundation - Chronic Kidney
Disease (NKF-CKD) guidelines.

8. Adequate liver function.

9. Negative serum pregnancy test (for women of child bearing age).

Exclusion Criteria:

2. Secondary MPGN.

3. Presence or suspicion of active infection.

4. Pregnancy.

5. Concomitant malignancies, Major psychiatric disorder. Significant cardiac or pulmonary
disease and any other disease, metabolic dysfunction, physical examination finding, or
clinical laboratory suspicion of a disease/condition that contraindicates the use of
an investigational drug or that may affect the interpretation of the results or render
the patient at high risk from treatment complications.

6. Laboratory Exclusion Criteria (Screening):

- Hemoglobin:< 8.5 gm/dL

- Platelets:< 100,000/mm

- Total bilirubin, Aspartate amino transferase, alkaline phosphatase > 2.5 x Upper
Limit of Normal unless related to primary disease

- Positive Hepatitis B or C serology

- Positive human immunodeficiency virus
