About

Treatment with combination ACTHar gel and Tacrolimus therapy or ACTHar gel therapy alone in lowering urinary protein to creatinine (UP/Cr) ratios

Full 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.
