CHESTERFIELD, United Kingdom, Nov. 21, 2016
CHESTERFIELD, United Kingdom, Nov. 21, 2016 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today confirmed that it will initiate a company-sponsored, Phase 2 proof-of-concept clinical trial to assess the efficacy of H.P. Acthar® Gel (repository corticotropin injection) in patients with Amyotropic Lateral Sclerosis (ALS, also known as Lou Gehrig's disease). The study is expected to begin in the first half of 2017.
Mallinckrodt also announced the U.S. Food and Drug Administration (FDA) has granted the company's request for a Fast Track designation for its Acthar Investigational New Drug (IND) application in patients with ALS. The company is working closely with the FDA as it establishes the Phase 2 study design.
"We recently completed our pilot study of Acthar in ALS patients, and are pleased to report that the primary objectives of the study were met. The trial explored the safety and tolerability of four potential Acthar dosing regimens in ALS patients," said Steven Romano, M.D., Executive Vice President and Chief Scientific Officer at Mallinckrodt. "Although the pilot study was not designed to generate controlled evidence regarding efficacy, we conducted a number of exploratory analyses, including a comparison of the course of disease observed in a small set of patients continuing on Acthar for 36 weeks versus a historical, placebo-treated population. Differences observed suggested further study was appropriate. The study data have also allowed us to select a dose regimen to study the drug further in a rigorous controlled trial. This next proof-of-concept study will evaluate the effects of Acthar on established measures of disease symptoms and progression, enabling us to assess the potential value Acthar may bring to patients with this devastating disease."
The FDA's Fast Track designation is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need. The purpose is to get important new drugs to the patient earlier. The Fast Track program addresses a broad range of serious conditions.
Mallinckrodt's investment into this clinical trial illustrates a tenet of its Acquire to Invest strategy, applying substantial resources on building a robust, organic pipeline.
About the Pilot Study
The 8-week, randomized, open-label evaluation examined the acute safety and tolerability of four different dosing regimens for Acthar in patients with ALS. The study included an optional 28-week, open-label extension phase to gather additional longer-term safety and tolerability data.

About Amyotrophic Lateral Sclerosis
ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their demise and when the motor neurons die, the ability of the brain to initiate voluntary movement and muscle control muscle movement is lost. With voluntary muscle action progressively affected, people may lose the ability to speak, eat, move and breathe.
There is increasing evidence that neuro-inflammation accompanies the death of motor neurons in ALS. Several places in the inflammatory events that appear to accompany ALS might be amenable to drug action that could help in the disease. Research in the field is continuing to find new approaches to implement an anti-inflammatory strategy in treating ALS1.
About H.P. Acthar Gel (repository corticotropin injection)
H.P. Acthar Gel (repository corticotropin injection), is an injectable drug approved by the FDA for the treatment of 19 indications. Of these today the majority of Acthar use is in these indications:
