Phase 2 Proof-of-Concept Study Design and Results
The multi-center, randomized, double-blind, placebo-controlled Phase 2 study was designed to evaluate ADS-5102 in MS patients with walking impairment for four weeks. The study enrolled 60 MS patients who had impaired walking speed at baseline. The primary study objective was to evaluate the safety and tolerability of 340 mg ADS-5102 dosed once daily at bedtime. Exploratory efficacy analyses included the change from baseline to week four in the T25FW, the TUG, the 2 Minute Walk Test (2MWT) and the Multiple Sclerosis Walking Scale-12 (MSWS-12). Other outcome measures included assessments of fatigue, cognition and depression. Background MS medications were not changed during the course of the study.
Efficacy results were obtained from a modified intent-to-treat population that included 56 subjects who received at least one dose of ADS-5102 and provided at least one post-baseline walking assessment. An analysis using the mean changes from baseline to week four efficacy measures showed an approximate 17 percent placebo-adjusted improvement in walking speed in the T25FW test (p < 0.05) and an approximate three second placebo-adjusted improvement in TUG (p < 0.10). No effects were noted for fatigue, cognitive dysfunction or depression.
ADS-5102 was generally well tolerated in this study population. One serious adverse event was reported in the study, suspected serotonin syndrome, reported as drug related by an investigator. The most frequent adverse events (AEs) reported in the ADS-5102 treatment group were dry mouth, constipation and insomnia. Five ADS-5102 patients and no placebo patients discontinued treatment due to AEs.

ADS-5102 is a chrono-synchronous amantadine therapy with potential applications across a number of chronic neurologic disorders. Adamas is focusing initial development on the treatment of levodopa-induced dyskinesia (LID) in patients with Parkinson's disease. A New Drug Application (NDA) supporting ADS-5102 for the treatment of LID in patients with Parkinson's disease is under review by the

Adamas is developing new medicines to improve the daily lives of those affected by chronic neurologic disorders, including Parkinson's disease, multiple sclerosis, epilepsy and Alzheimer's disease. Adamas has pioneered a platform to develop medicines, called chrono-synchronous therapies, for chronic neurologic disorders based on an understanding of the time-dependent biologic processes responsible for disease activity and drug response to potentially achieve symptomatic relief without tolerability issues. The company's most advanced product candidate, ADS-5102, is in development for levodopa-induced dyskinesia (LID) in patients with Parkinson's disease and for walking impairment in patients with multiple sclerosis. An NDA supporting ADS-5102 for the treatment of LID in patients with Parkinson's disease is under review by the
