Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00805753 ↗	Dose-Finding Pilot Study of ACTH in Patients With Idiopathic Membranous Nephropathy	Completed	Mallinckrodt	Phase 1	2009-01-01	This pilot study is aimed at demonstrating the effectiveness of ACTH (H.P. Acthar Gel) on the lipid profile and proteinuria in participants with MN. ACTH or adrenocorticotrophin is a hormone produced by the pituitary gland (a gland at the base of your brain) that is involved in stimulating your adrenal glands to secrete a number of steroid products (e.g. cortisol, aldosterone, corticosterone, and others) that are important in keeping you alive. The drug used in this study has been approved by the Food and Drug Administration (FDA) for routine clinical use in the treatment of patients with proteinuria and patients with idiopathic nephrotic syndrome such as idiopathic MN. However, the most adequate dose to use has not been adequately assessed. This is the reason for conducting this research study.

NCT00854750 ↗	Modeling and Treating the Pathophysiology of Demyelination in Multiple Sclerosis	Terminated	Mallinckrodt	Phase 4	2009-05-01	The investigators principal hypothesis is that INO and optic neuritis are objective, quantitative, and reproducible models for corroborating the hypothesis that changes in core body temperature are associated with the reversible and stereotypic decay in axonal conduction and that ACTHAR can serve to prevent such changes. The application of ocular motor and optic nerve measures appears to constitute a useful paradigm to detect and monitor responses to therapeutic strategies that stabilize nerve cell membranes in response to temperature induced decay in axonal conduction mechanisms, with implications on activities of daily life that are dependent upon vision (reading, driving, walking, work performance).

NCT01021540 ↗	Prospective Study Evaluating the Effect of Repository Corticotropin in the Treatment of Various Nephrotic Syndromes	Completed	Arizona Kidney Disease and Hypertension Center	Phase 4	2009-12-01	To determine if H.P. Acthar Gel (repository corticotrophin) has the same anti-proteinuric effects seen with the synthetic ACTH analogue in Europe.
NCT01028287 ↗	Adrenocorticotropic Hormone (ACTH) Treatment of Nephrotic Range Proteinuria in Diabetic Nephropathy (NRDN)	Completed	Mallinckrodt	Phase 4	2009-05-01	This is a prospective open labeled trial examining the efficacy of ACTHar Gel (porcine ACTH) on the level of proteinuria in patients with diabetic nephropathy and nephrotic range proteinuria.
