First Patient Enrolled in Mallinckrodt Phase 4 Trial of H.P. Acthar® Gel (Repository Corticotropin Injection) for Multiple Sclerosis Relapse

STAINES-UPON-THAMES, United Kingdom, May 23, 2017 /PRNewswire/ — Mallinckrodt plc a leading global specialty pharmaceutical company, today confirmed enrollment of the first patient in the company’s Phase 4 pilot study assessing the efficacy of H.P. Acthar® Gel (repository corticotropin injection) for the management of exacerbations of relapsing and remitting multiple sclerosis (RRMS) in patients whose relapse symptoms have not responded to a course of high-dose corticosteroids.

“Some MS patients may have relapse symptoms that don’t resolve with steroid therapy, and in my experience, H.P. Acthar Gel may provide benefit in these cases,” said Aaron Miller, M.D., a program advisor and participating site investigator from the Icahn School of Medicine at Mount Sinai in New York. “This study is an important step to confirming the appropriate patient type for this product as an approved and appropriate treatment for MS exacerbations.”

H.P. Acthar Gel is U.S. Food and Drug Administration (FDA)-approved for treatment of acute exacerbations of multiple sclerosis in adults.

“Mallinckrodt is committed to providing alternative treatment options to patients who need them,” said Steven Romano, M.D., Chief Scientific Officer and Executive Vice President at Mallinckrodt. “Clinical experience and current labeling support the use of Acthar to speed recovery from relapses in MS. We are pleased to enroll the first patient in the OPTIONS trial to better understand the patients who will benefit from Acthar therapy, and to support its role in the management of RRMS.”

About the OPTIONS Trial
The Phase 4 clinical study is titled “A Multicenter, Randomized, Double-Blind, Placebo-Controlled Parallel Group, Pilot Study to Assess the Efficacy and Safety of H.P. Acthar Gel in Subjects With Relapsing-Remitting Multiple Sclerosis”. The study will enroll patients with MS relapses of moderate severity and symptoms that have not adequately improved following a typical course of high dose IV or oral corticosteroid therapy, then randomize them to receive additional treatment with H.P. Acthar Gel or placebo in blinded fashion. 

Improvement in relapse symptoms will be assessed using several standard MS disease activity measures, including the Expanded Disability Status Scale (EDSS), MS Impact Scale (MSIS-29), and Clinical Global Impressions-Improvement Scale (CGI-I). Because this trial targets only a subset of RRMS patients experiencing relapses who have not responded acutely to corticosteroid therapy, the study may take a number of years to recruit.
