Minocycline in Clinically Isolated Syndromes (CIS)

Summary

The aim of the trial is to demonstrate that 100 mg of oral minocycline twice daily reduces the conversion of CIS to McDonald Criteria MS (McDMS) by an absolute 25% as compared to placebo, over a 6 month follow-up period (primary outcome). A key secondary outcome is to confirm that this early treatment benefit is maintained at two years.
