Participants who meet inclusion criteria will start placebo treatment by taking olive oil
for 2 months. This period will include screening activities including 3 monthly MRIs. Those
with 2 enhancing lesions on three placebo run-in period MRIs will continue in the study and

and 6 months after treatment.

Inclusion Criteria:

brain MRI in the past 12 months

4. at least two gadolinium enhancing lesions on three brain MRIs obtained during the
placebo run-in period

5. women of childbearing potential may participate provided that they are using adequate
birth control methods for the duration of the study. Women of childbearing potential
