Clinical Trial Summary

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.

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.

Eligibility

Inclusion Criteria:

• Male/Female age > 18

• Estimated Glomerular Filtration Rate > 25 mls/min calculate by the Chronic Kidney Disease-EPI formula
• Protein/creatinine ratio > 2000 mg/gm 5) Note: If protein/creatinine less than 2000 mg/gm, a formal 24- hour urine collection for total protein can be performed. The total 24-hour protein will need to >/= 2000mg.
• Blood pressure targeted to < 140/90 at the time of randomization
• Patients with Monoclonal Gammopathy without history of myeloma will be eligible.
• Patients with monoclonal staining for fibrillary fibers will be excluded
• Patients with Type II non-insulin dependent diabetes will be eligible provided the renal biopsy does not show nodular Kimmelstiel Wilson lesions

Exclusion Criteria:

• Patients with MGUS and history of myeloma will not be eligible
• Patients with active viral production of either hepatitis B or C as evidence by historical polymerase chain reaction test positive for active viral shedding
• HIV seropositivity
• Renal biopsy data with > 50% Interstitial Fibrosis
• Patient with active or a known history lymphoma
• Patients with insulin dependent diabetes mellitus will be excluded Note: patients with Type II diabetes mellitus that are well controlled without the need for insulin will be eligible for the study.
• Patients with Type II non-insulin dependent diabetes will be eligible provided the renal biopsy does not show nodular Kimmelstiel Wilson lesions.
• Patients receiving steroids, mycophenolate mofetil, cyclophosphamide, Azathioprine or other immunosuppressive agent with 4 weeks of study randomization Note: Washout of these medications will be allowed at the screening visit

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	To determine if patients with concurrent Type II diabetes mellitus resulted in hyperglycemia, increased proteinuria, loss of renal function or led to immunosuppressive therapies	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.	24 months
Primary	The change in UP/CR ratio with treatment of Acthar gel 80 units subcutaneous 2 times a week alone	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	12 months
Primary	The change in UP/CR ratio with treatment of Acthar gel 80 units subcutaneous 2 times a week in combination with oral Tacrolimus	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.	12 months
Secondary	The relative change in protein/creatinine ratio at 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.	24 months
Secondary	Percentage of patients complete or partial response	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	12 months
Secondary	The change in Estimated Glomerular Filtration Rate	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.	24 months
Secondary	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	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	12 months
