Brief Summary:
This Phase 2 study is intended to serve as a proof of concept for potential treatment with laquinimod in patients with PPMS. The study is also aimed at evaluating 2 doses of laquinimod in this population.

Condition or disease Intervention/treatment Phase
Primary Progressive Multiple Sclerosis Drug: Placebo Drug: Laquinimod Phase 2

Detailed Description:

Due to serious cardiovascular adverse events, Data Monitoring Committee (DMC) made a recommendation to stop all laquinimod treatment arms above 0.6 mg in the multiple sclerosis (MS) trials; therefore the 1.5 mg treatment arm in the ARPEGGIO study was discontinued as of 01 January 2016.

The DMC did not identify any definite cardiovascular risk in the 0.6 mg treatment arm, but felt that long term monitoring for emergence of any potential signal was necessary. Therefore, the 0.6 mg treatment arm was continued while the sponsor closely monitored cardiovascular events in all laquinimod studies. Prior to 01 January 2016, eligible patients were randomized in a 1:1:1 ratio into 1 of the following treatment arms (a total of 286 patients were randomized 1:1:1 prior to

01 January 2016):

  • Laquinimod 0.6 mg daily
  • Laquinimod 1.5 mg daily
  • Daily placebo

As of 01 January 2016, following the decision to discontinue the laquinimod 1.5 mg dose arm, additional eligible patients (87 patients) who were enrolled were randomized in a 1:1 ratio into one of the following treatment arms:

  • Laquinimod 0.6 mg daily
  • Daily placebo

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 374 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)

Primary Outcome Measures :
  1. Percent Brain Volume Change (PBVC) From Baseline to Week 48 Using a Repeated Measures ANCOVA Model [ Time Frame: Baseline (at least 14 days but not more than 6 weeks prior to Day 1), Weeks 24, 48 and including early termination visits ]
    Brain atrophy (BA) was measured using magnetic resonance imaging (MRI) scans of the brain. BA was analyzed using baseline-adjusted repeated measures analysis of covariance (ANCOVA- SAS® PROC MIXED) in which 1 contrast was constructed in order to compare between laquinimod 0.6 mg and placebo. The statistical model was a repeated measures analysis of covariance with treatment group, week, treatment group by week interaction, normalized brain volume at baseline, natural logarithm of T2 lesion volume at baseline, and country as fixed effects. Only on-treatment observations (include all the assessments done up to one month after the last dose of the study drug) were included. Values are adjusted means. The cancelled laquinimod 1.5 mg treatment arm was not included in the repeated measures ANCOVA model analysis. However PBVC by visit data are offered in outcome #2.

  2. Percent Brain Volume Change (PBVC) From Baseline to Weeks 24 and 48 [ Time Frame: Baseline (at least 14 days but not more than 6 weeks prior to Day 1), Weeks 24, 48 ]
    Brain atrophy (BA) was measured using magnetic resonance imaging (MRI) scans of the brain. Early termination scans of participants who discontinued the study after week 36 are considered scans at week 48.


Secondary Outcome Measures :
  1. Percentage of Participants With 12-Week Confirmed Disability Progression (CDP) As Measured by Expanded Disability Status Scale (EDSS) up to Week 48 [ Time Frame: Baseline (Week 0), Weeks 12, 24, 36, 48 (end if treatment if < 48 weeks) ]
    CDP was defined as increase in EDSS of >=1 point from baseline EDSS, if EDSS at entry is ≤5.0 or increase of >=0.5 point, if EDSS at entry is >=5.5. This increase should be confirmed after at least 12 weeks. Progression cannot be confirmed during a protocol defined relapse. EDSS is a method of quantifying disability in multiple sclerosis and monitoring changes in the level of disability over time. The EDSS scale ranges from 0 to 10 in 0.5 unit increments with 0=no disability and 10=death due to MS. Only an Examining Neurologist administered the EDSS. The Examining Neurologist did not have access to the patient's medical records or source documents, including previous EDSS forms or adverse events. If a patient died due to MS disease progression, the patient was analyzed as having CDP with the time to CDP as the onset date of progression. If a patient died due to MS before having progression, then the time to disability progression was censored using the date of death.

  2. Percentage of Participants With 12-Week Confirmed Disability Progression (CDP) As Measured by Expanded Disability Status Scale (EDSS) or the Timed 25-foot Walk (T25FW) Test up to Week 48 [ Time Frame: Baseline (Week 0), Weeks 12, 24, 36, 48 (end if treatment if < 48 weeks) ]

    CDP was defined as

    increase in EDSS of >=1 point from baseline EDSS, if EDSS at entry is ≤5.0 or increase of >=0.5 point, if EDSS at entry is >=5.5 confirmed after at least 12 weeks, OR increase of >= 20% from baseline in the T25FW test, confirmed after at least 12 weeks.

    EDSS quantifies disability in MS and monitors changes in the level of disability over time. The EDSS scale is 0-10 in 0.5 unit increments with 0=no disability and 10=death due to MS. The T25-FW is a quantitative mobility and leg function performance test based on the average time of two trials in which participants walk 25 feet as quickly as possible. Increasing time scores indicate increasing impairment.

    If a patient died due to MS disease progression, the patient was analyzed as having CDP with the time to CDP as the onset date of progression. If a patient died due to MS before having progression, then the time to disability progression was censored using the date of death.


  3. Change From Baseline for the Timed 25-foot Walk (T25FW) Score at Weeks 12, 24, 36 and 48 [ Time Frame: Baseline (Week 0), Weeks 12, 24, 36, 48 ]
    The T25FW is a quantitative mobility and leg function performance test based on the average time of two trials in which participants walk 25 feet as quickly as possible. In cases when a patient could not complete a T25FW trial due to the physical limitations, a value of 180 seconds was assigned for that trial (this is the maximal possible value for the T25FW test). Increasing time scores indicate increasing impairment. Baseline values are summaries of observed values. Week values are change from baseline values.

  4. Number of New T2 Brain Lesions at Week 48 [ Time Frame: Baseline (Week 0), 48 weeks ]
    Inflammatory disease activity was assessed by magnetic resonance imaging (MRI) measurement of the number of new T2 lesions at week 48 as compared to baseline. Scans of patients who discontinued the study after week 36 are considered scans at week 48, and are included in week 48.

  5. Participants With Treatment-Emergent Adverse Events (TEAEs) [ Time Frame: Day 1 up to Week 130 (longest duration of treatment) ]
    An adverse event (AE) was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an AE which prevents usual activities. Relationship of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
