• Status: Completed
• Trial end date: 2018-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This study is designed to answer whether patients with progressive IgA nephropathy, who receive Acthar (ACTH) gel injection at a dose of 80 units subcutaneously twice weekly for 6 months is effective in inducing improvement in proteinuria and renal function.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Mayo Clinic
• Collaborator: Mallinckrodt
• Treatments: Adrenocorticotropic Hormone

Criteria

Inclusion:

• Proteinuria > 1000 mg/24h despite documented ACEi/ARB therapy and adequate blood pressure control for > 3 months.

• Quantified 24h creatinine clearance > 30 ml/min/1.73m2.

• Blood pressure < 130/80 mmHg at > 75% of the readings.

• Henoch Schoenlein Purpura (HSP): Patients with biopsy proven IgA nephropathy and clinical features consistent with Henoch Schonlein Purpura will be considered eligible for the study.

• Patient must be able to receive injections to be enrolled in the study.

• Patient must have a kidney biopsy slide on file - that can be sent to Mayo Clinic.

Exclusion:

• Patients receiving therapy with oral prednisone or glucocorticoid equivalent in the past 3 months.

• Patients who had received immunosuppressive therapy including cyclophosphamide, mycophenolate mofetil (MMF), cyclosporine, tacrolimus or azathioprine in the last 6 months.

• Current or recent (within 30 days) exposure to any investigational drug.

• History of psychiatric disorder that would interfere with normal participation in this protocol.

• Significant cardiac or pulmonary disease (including obstructive pulmonary disease).

• Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or 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 complication.

• Inability to comply with study and follow-up procedures.
