A Phase IIa Study of NT-KO-003 for Multiple Sclerosis

A Phase IIa Multicenter Double Blind Study to Evaluate the Efficacy and Safety of Low Doses of Oral NT-KO-003 for the Treatment of Multiple Sclerosis

The aim of the study is to assess the efficacy and safety of NT-KO-003 in the treatment of relapsing remitting multiple sclerosis, comparing two doses versus placebo.

This is a Phase IIa study, double blind, placebo Controlled, Multicenter Study that will involve up to 99 patients with relapsing remitting multiple sclerosis.

After signing the informed consent form, subjects will be randomized to three treatments arms: placebo, NT-KO-003 low dose or NT-KO-003 high dose. Treatment will continue daily during 6 months. A MRI and a clinical evaluation will be performed monthly. Safety will be assessed during the 6 months treatment and until 15 days after the finalization of the treatment.

Patients will be allowed to continue in the same arm of the study, in a blinded way, until the study finalizes as optional extension treatment. Patient will sign the Extension Informed Consent and a MRI will be performed for those patients still in treatment after 12 months of the inclusion in the core study (visit 0).
