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
Official title: A Phase III Double-blind, Randomized, Placebo-controlled Trial of Minocycline in Clinically Isolated Syndromes (CIS) and Early Single Relapse Multiple Sclerosis (MS)
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention
Primary outcome: 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.
Secondary outcome: To confirm that this early treatment benefit is maintained at two years.
- Minocycline 100 mg bid orally compared to identical placebo
- Clinically Isolated Syndrome (CIS): Patients with a first clinical demyelinating event
suggestive of multiple sclerosis (At baseline participants may meet 2010 McDonald
diagnostic criteria for MS, but not 2005 criteria)
- Men and women, aged 18-60y, first event within the previous 180 days; brain magnetic
resonance imaging (MRI) with at least two brain T2 lesions which are at least 3 mm in
diameter, and at least one of which is ovoid or periventricular or infratentorial.
- Up to 24 months of study drug (Up to 12 months of study drug for patients recruited
after December 31, 2012)
- Patients will be discontinued from the study when they convert to McDMS based on the
2005 McDonald definition.
- 12 Canadian MS Clinics
- A total of 154 patients will be randomized. Because 30% of screened patients with CIS
who are clinically eligible are not expected to meet the MRI criteria for inclusion, up
to 280 patients will be screened.
Minimum age: 18 Years.
Maximum age: 60 Years.
- Age between 18 and 60 years.
- First focal clinical episode suggestive of demyelinating disease within the previous
180 days (measured from onset of the first symptom to treatment start), based on the
appearance of a neurological abnormality, present for at least 24 hours.
- Objective clinical evidence must be present or documented. Patients will be included
irrespective of whether the first clinical demyelinating episode was monosymptomatic
(i. e. clinical evidence of a single lesion) or polysymptomatic (i. e. clinical
evidence of more than one lesion).
- At least two lesions on the T2-weighted brain MRI* scan at least one of which is
ovoid or periventricular or infratentorial. MRI eligibility will be determined
centrally by the UBC MS/MRI Research Group.*One lesion on spinal MRI may substitute
for one brain lesion as per the 2005 McDonald Criteria.
- Sexually active women of child-bearing potential must agree to use adequate
- Written informed consent
- Any disease other than MS that could better explain the patient's signs and symptoms.
- Any previous clinical event reasonably attributable to acute demyelination,
regardless of whether medical attention was obtained.
- Complete transverse myelitis or bilateral optic neuritis. A waiver can be obtained
for bilateral optic neuritis but must be obtained prior to randomization. Waivers
must be approved by 3 neurologists including a member of the Clinical Eligibility /
Endpoint Committee, a member of the DSMC, and by an experienced MS
