Brief summary
Treatment with combination ACTHar gel and Tacrolimus therapy or ACTHar gel therapy alone in lowering urinary protein to creatinine (UP/Cr) ratios
Detailed description
This is a multicenter, Phase 4, prospective, open labeled study to compare the safety, tolerability, and efficacy of a 12month course of ACTHar Gel and Tacrolimus therapy or ACTHar gel therapy alone in lowering urinary protein to creatinine (UP/Cr) ratios. The addition of tacrolimus patients exhiba partial to ACTH resulted in a further reduction in Fibrillary. Spe #1-will randomize with biopsy proven DNA-JB9 positive Fibrillary glomerulopathy to receive course of ACTHar gel alone at 80 units per week or in combination with oral Tacrolimus at 1 mg BID Hypothesis Treatment with ACTHar Gel with oral Tacrolimus will result in a higher eGFR after 24 months of follow up than patients randomized to ACTHar gel therapy alone. Hy3: Combination therapy of ACTHar Gel and Tacrolimus in patients with DNA-JB9 positive Fibrillary will lead to significant markers of podocyte injury compared ACTHar Gel alone.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| change in UP/Cr ratio in patients with biopsy proven Fibrillary after treated with ACTHar gel alone OR in combination with oral Tacrolimus | 12 months | The change in UP/Cr ratio in patients with biopsy proven Fibrillary after 12 months of treatment with ACTHar gel (80 units SQ 2X/week) alone OR in combination with oral Tacrolimus (1.0 mg PO BID). The change in UP/Cr for each group will also be compared to baseline UP/Cr ratios prior to randomization |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| relative change in UP/Cr | 24 months | The relative change in UP/Cr at 24 months (12 months after stopping both ACTH and Tacrolimus) in the ACTHar gel group and the ACTHar gel + Tacrolimus group. |
| T that achieves complete, partial or clinical responses | 12 months | The percentage of patients in the ACTHar gel alone ACTHar gel + Tacrolimus group that achieves complete, partial or clinical responses after 12 months of therapy |
