comparative and efficacy study of acthar gel alone or in combination with tacrolimus in fibrillary glomerulopathy

Conditions: Renal Disease

Summary: treatment with combination acthar gel and tacrolimus therapy or acthar gel therapy alone in lowering urinary protein to creatinine (up/cr) ratios

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.
