Last verified: December 2016
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 0.6 mg/day or 1.2mg/day in subjects with RRMS.

Condition Intervention Phase

Drug: Laquinimod 0.6 mg
Drug: Matching Placebo
Drug: Laquinimod 1.2 mg
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: 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 Oral Doses of Laquinimod (0.6 mg/d or 1.2 mg/d) in Subjects With Relapsing Remitting Multiple Sclerosis (RRMS)

Primary Outcome Measures:
  • Time to Confirmed Disease Progression (CDP) in Period 1 [ Time Frame: 24 months (Period 1) ]
    CDP is defined as an increase in Kurtzke's Expanded Disability Status Scale (EDSS) of 1 point or more from baseline for subjects with baseline EDSS of ≤5.0, or an increase 0.5 points or more from baseline for subjects with baseline EDSS of 5.5. The EDSS rates a person's disability due to multiple sclerosis severity, ranging from 0 (normal neurological exam) to 10 (death due to MS). The higher score represents more severe disability. The outcome measure is the time recorded from Baseline until the subject meets this definition of CDP.

Secondary Outcome Measures:
  • Percent change in brain volume [ Time Frame: Change from Baseline to 15 Months ]
    This is a measure of brain volume and will be assessed by an MRI. Brain atrophy is defined as the percent change in brain volume from baseline to month 15

  • The time to first confirmed relapse during Period 1 [ Time Frame: 24 months (Period 1) ]

Other Outcome Measures:
  • Number of Participants with Adverse Events [ Time Frame: 24 months (Period 1) ]
  • Number of Participants with Abnormal Vital Signs [ Time Frame: 24 months (Period 1) ]
  • Number of Participants with Abnormal ECG Findings [ Time Frame: 24 months (Period 1) ]
  • Number of Participants with Abnormal Clinical Laboratory Parameters [ Time Frame: 24 months (Period 1) ]

Enrollment: 2199
Study Start Date: February 2013
Estimated Study Completion Date: April 2017
Estimated Primary Completion Date: March 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Laquinimod 0.6 mg
Two capsules, one containing 0.6 mg laquinimod and the other containing matching placebo, to be administered orally once daily during both Periods 1 and 2.
Drug: Laquinimod 0.6 mg
Experimental: Laquinimod 1.2 mg

Two capsules containing 0.6 mg laquinimod to be administered orally once daily during both Periods 1 and 2.

NOTE- As of January 2016, this arm has been discontinued.

Drug: Laquinimod 1.2 mg
Placebo Comparator: Placebo
Two capsules containing placebo (matching to the 0.6 mg) to be administered orally once daily during Period 1.
Drug: Matching Placebo

Detailed Description:

Eligible subjects with confirmed relapsing-remitting multiple sclerosis will be randomized in a 1:1:1 ratio into one of the following treatment arms: Laquinimod capsules 0.6 mg, Laquinimod capsules 1.2 mg and matching placebo. The study will be comprised of two treatment periods:

Period 1: Double-blind Placebo-controlled (DBPC) period: not more than 24 months of once-daily, oral administration of either laquinimod 0.6 mg, 1.2 mg or matching oral placebo.

The Sponsor will declare closing of Period 1 for all subjects when 260 events of confirmed disease progression (CDP) have occurred or when all ongoing enrolled subjects completed 24 months in Period 1 (whichever occurs first).


Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects must have a confirmed and documented MS diagnosis as defined by the Revised McDonald criteria, with relapse onset disease or a relapsing-remitting disease course.
  • Subjects must be ambulatory with Kurtzke EDSS score of 0- 5.5 in both screening and randomization visits.
  • Subjects must be in a stable neurological condition, relapse-free and free of any corticosteroid treatment [intravenous (IV), intramuscular (IM) and/or per os (PO)] or adrenocorticotrophic hormone (ACTH), 60 days prior to randomization.
  • Subjects must have experienced at least one documented relapse in the 12 months prior to randomization.
  • Subjects must be between 18 and 55 years of age at screening, inclusive.
  • Subjects 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 duration of the study and until 30 days after the last dose of study medication. Acceptable methods of birth control include: intrauterine devices, barrier method (condom or diaphragm with spermicide) and hormonal methods of birth control (e.g. oral contraceptive, contraceptive patch, and long-acting injectable contraceptive).
  • Subjects must be able to sign and date a written informed consent prior to entering the study.

  • Subjects with a clinically significant or unstable medical or surgical condition or any other condition that cannot be well-controlled by the allowed medications permitted in the study protocol that would preclude safe and complete study participation, as determined by medical history, physical examinations, ECG, laboratory tests MRI or chest X-ray. Such conditions may include:

    • A major cardiovascular event (e.g. myocardial infarction, acute coronary syndrome, de-compensated congestive heart failure, pulmonary embolism, coronary revascularization) that occurred during the past 6 months prior to randomization.
