A Phase 2b/3, Multi-Center, Randomized, Double-Blind, Placebo-Controlled, 12 Month Clinical Trial to Evaluate the Efficacy and Safety of MN-166 (Ibudilast) Followed by an Open-Label Extension Phase in Subjects With Amyotrophic Lateral Sclerosis
Details
This is a Phase 2b/3 multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy, safety and tolerability of MN-166 followed by an open-label extension phase compared to matching placebo in subjects diagnosed with ALS.
The study will consist of a screening phase (up to 30 days) followed by a double-blind phase (12 months). Following the screening phase, subjects who continue to meet entry criteria will be randomly assigned to one of two treatment groups: MN-166 or matching placebo in a 1:1 ratio. Upon completion of the double-blind phase, subjects will be given the option to continue to the Open-label Extension Phase for a period of six months.
