Brief Summary

Membranous Nephropathy (MN) is an immune-mediated kidney disease that affects the glomerulus or the filter that removes toxins from the blood. Damage to the membrane that separates blood from urine results in loss of protein into the urine (proteinuria) and in some cases loss of kidney function.There is no standard specific treatment for MN. ACTH has a pronounced lipid-lowering effect in healthy individuals, in steroid-treated patients with renal disease and in hemodialysis patients Some studies suggest that prolonged synthetic ACTH therapy may represent an effective therapy in patients with idiopathic MN, more extensive randomized studies with longer follow-up are needed before therapeutic recommendations can be made. We propose to do a pilot study to test the hypothesis that biologic ACTH, a slow-release formulation of corticotropin extracted from porcine pituitary glands (H.P. Acthar gel) will be effective in reducing proteinuria and improving lipid profile in patients with idiopathic MN.

  3 months

• Adverse effects

  Throughout three months of this study and for nine months follow-up

Study Arms (2)

ACTH (HP Acthar gel) 40 units

ACTIVE COMPARATOR

Drug: Adrenocorticotrophic hormone ACTH

ACTH (HP Acthar gel) 80 units

ACTIVE COMPARATOR

Drug: Adrenocorticotrophic hormone ACTH

Interventions

Adrenocorticotrophic hormone ACTH DRUG

There will be two arms to the study: one arm receive 40 units and the second arm 80 units of the ACTH gel subcutaneously both given in a dose escalating frequency beginning at once every two weeks escalating to a maximum of twice per week over a total of three months exposed.An ammendment(approved by Health Canada and the UHN IRB allows an additional 1 month of the perscribed therapy of ACTH )if there is an improvement in proteinuria at the end of the 3 month exposure.

Also known as: HP Acthar gel

ACTH (HP Acthar gel) 40 units; ACTH (HP Acthar gel) 80 units

Eligibility Criteria

• Age: 18 Years - 72 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients need to be treated with an ACEI and/or ARB, for at least 3 months prior to ACTH treatment and have adequately controlled blood pressure (BP \<130/75 mm Hg in \>75% of the readings). Patients with documented evidence of \>3 months treatment with maximal Ang II blockade, target BP (BP \<130/75 mm Hg in \>75% of the readings) and who remain with proteinuria \>4.0g/24h may enter the ACTH phase of the study without the need to have the run-in/conservative phase of the study.
• Proteinuria as measured by Uprot/Ucr \> 4.0 on a spot sample aliquot from a 24-hour urine collection. The choice of Uprot/UCr is in accord with recent NKF-CKD guidelines.\[9\]
• Estimated GFR ≥ 40 ml/min/1.73m2 while taking ACEI/ARB therapy. The GFR will be estimated using the 4 variable MDRD equation as published in the NKF-CKD guidelines.\[9\] The same NKF-CKD guidelines also promote the use of estimated GFR (GFRest) values rather than serum creatinine levels or CrCl measurements as the preferred non-invasive method of determining glomerular filtration rates.\[9\]

You may not qualify if:

• Estimated GFR \< 40 ml/min/1.73m2, or serum creatinine \>2.0 mg/dl.
• Renal biopsy showing more than 30% glomerulosclerosis and/or tubular atrophy.
• Patient must be off glucocorticoid, calcineurin inhibitors (cyclosporin A, tacrolimus) or mycophenolic mofetil for \> 1 month, and alkylating agents or rituximab for \>6 months.
• Resistance to the following immunosuppressive routines e.g. steroids alone, calcineurin inhibitors plus or minus steroids, cytotoxic agents plus or minus steroids.
• Patients with active infections or secondary causes of MN (e.g. hepatitis B, SLE, medications, malignancies). Testing for HIV, Hepatitis B and C should have occurred \< 2 years prior to enrollment into the study.
• Type 1 or 2 diabetes mellitus: to exclude proteinuria secondary to diabetic nephropathy. Patients who have recent history of steroid induced diabetes but no evidence on renal biopsy performed within 6 months of entry into the study are eligible for enrollment.
• Pregnancy or nursing - for safety reasons.
• Acute renal vein thrombosis documented prior to entry by renal US or CT scan and requiring anticoagulation therapy.
