Detailed Description
A Multicenter, Comparative Safety and Efficacy Study of Acthar gel alone or in combination with oral Tacrolimus to reduce urinary proteinuria in patients with idiopathic DNAJB9 Positive Fibrillary glomerulopathy. This study will be a multi-center, prospective, randomized, open-labeled intervention trial of 34 patients randomized to 52 weeks of ACTHar gel alone or Acthar gel plus oral Tacrolimus.

Outcome Measures
Primary Outcome Measures
- The change in UP/CR ratio with treatment of Acthar gel 80 units subcutaneous 2 times a week alone [12 months]
The change in protein/creatinine ratio in patients with biopsy proven Fibrillary after 12 months of treatment with treated with Acthar gel (80 units subcutaneous 2 times a week) alone
- The change in UP/CR ratio with treatment of Acthar gel 80 units subcutaneous 2 times a week in combination with oral Tacrolimus [12 months]
The change in protein/creatinine ratio in patients with biopsy proven Fibrillary after 12 months of treatment with treated with Acthar gel 80 units 2 times a week subcutaneous week in combination with oral Tacrolimus 1.0 mg orally two times a day.
Secondary Outcome Measures
- The relative change in protein/creatinine ratio at 24 months [24 months]
The relative change in protein/creatinine at 24 months (12 months after stopping both Acthar and Tacrolimus) in the Acthar gel group and the Acthar gel plus Tacrolimus group.
- Percentage of patients complete or partial response [12 months]
The percentage of patients in the Acthar gel alone versus Acthar gel + Tacrolimus group that achieves complete, partial or clinical responses after 12 months of therapy
- The change in Estimated Glomerular Filtration Rate [24 months]
The change in Estimated Glomerular Filtration Rate between the Acthar gel and Acthar Gel plus Tacrolimus groups after 24 months of treatment with Acthar gel alone or in combination with oral Tacrolimus. In addition, we will also compare the relative change in eGFR between those patients receiving Acthar gel alone with those randomized to combination therapy.
- To compare the change in urinary biomarkers of Urinary VEGF 121, 165 189, and206, Urinary MCP-1, Urinary Synaptopodin, Urinary TGF-beta, Urinary Podocalyxin, and Urinary Nephrin [12 months]
To compare the change in urinary biomarkers at baseline and after 12 months of treatment with Acthar gel alone or in combination with Tacrolimus. The patients urinary biomarker levels after 12 months of therapy will be compared between the Acthar gel alone group and Acthar gel plus Tacrolimus group. Urinary VEGF 121, 165 189, and206 Urinary MCP-1 Urinary Synaptopodin Urinary TGF-beta Urinary Podocalyxin Urinary Nephrin
Other Outcome Measures
- To determine if patients with concurrent Type II diabetes mellitus resulted in hyperglycemia, increased proteinuria, loss of renal function or led to immunosuppressive therapies [24 months]
To determine whether Acthar gel therapy resulted in hyperglycemia in patients with concurrent Diabetes and whether that led to early termination from the study. We will also determine whether the presence of diabetes led to increased proteinuria over time, led to more rapid decline in renal function and altered the response to immunosuppressive therapy.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male/Female age > 18
