Study Endpoints

Primary Endpoints

To establish whether there is efficacy superiority of Natalizumab (Tyruko®) over placebo at 12 weeks in facilitating remyelination of previously demyelinated CNS lesions, as measured by MRI lesion magnetization transfer ratio (MTR).
12 weeks

Mean magnetisation transfer ratio (MTR) change in FLAIR-hyper-intense lesions at 12 weeks compared to baseline

Secondary Endpoints

To establish whether there is a difference between participants receiving Natalizumab (Tyruko®) or placebo at 24 weeks in P100 latency measured using visually evoked potentials (VEP).
0 and 24 weeks
To establish whether there is a difference between participants receiving Natalizumab (Tyruko®) or placebo at 24 weeks in number and occurrence of adverse events.
24 weeks
To establish whether there is a difference between participants receiving Natalizumab (Tyruko®) or placebo at 24 weeks in facilitating remyelination of previously demyelinated CNS lesions using Magnetisation transfer ratio (MTR).
