Efficacy and Safety of Neramexane Mesylate in Congenital Idiopathic Nystagmus and Acquired Nystagmus: a Randomized, Double-blind, Placebo-controlled, Single Center, Proof of Concept Study Using a Two-period Cross-over Design

The purpose of this study is to investigate the safety and efficacy of neramexane mesylate in the treatment of congenital idiopathic nystagmus (CIN) in comparison to placebo. In addition, a subgroup of multiple sclerosis (MS) patients suffering from acquired nystagmus will be included; this subgroup will be analyzed in an exploratory manner only.
