Study Endpoints
Primary Endpoints
Change in the sum of T1 Gd-enhancing lesions as reflected by MRI
46 weeks

Change in the sum of T1 Gd-enhancing lesions measured at pre-treatment (weeks -10 \[screening\], -6 and 0 \[baseline\]) to the sum of T1 Gd-enhancing lesions measured in the last study trimester (weeks 28, 32 and 36 \[termination\]).

To evaluate the add-on treatment effect of oral minocycline in subjects treated with daily injection of GA as reflected by number of MRI T1 Gd-enhancing lesions in T1-weighted images.
