A Multinational, Multicenter, Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Study Followed by an Active Treatment Period, to Evaluate the Efficacy, Safety and Tolerability of Two Doses of Oral Administration of Laquinimod (0.6 mg/Day or 1.2 mg/Day) in Patients With Relapsing Remitting Multiple Sclerosis (RRMS)

This is a multinational, multicenter, randomized, double-blind, parallel-group,
placebo-controlled study followed by active treatment, to evaluate the efficacy, safety and
tolerability of two doses of oral administration of laquinimod in participants with RRMS. The
study has 2 periods: Period 1, the double-blind, placebo-controlled period (up to 24 months)
and Period 2, the active treatment period (24 months).

defined by the Revised McDonald criteria, with relapse onset disease or a
relapsing-remitting disease course.

- Participants must be ambulatory with Kurtzke's expanded disability status scale (EDSS)
score of 0 to 5.5 in both screening and randomization visits.

- Participants must be in a stable neurological condition, relapse-free and free of any
corticosteroid treatment [intravenous (IV), intramuscular (IM) and/or per os
(PO)/oral] or adrenocorticotrophic hormone, 60 days prior to randomization.

- Participants must have experienced at least one documented relapse in the 12 months
prior to randomization.

- Participants must have disease duration of not more than 15 years.

- Women of child-bearing potential (for example, women who are not postmenopausal or
surgically sterilized) must practice an acceptable method of birth control for 30 days
before taking the study drug and two acceptable methods of birth control during the
