The purpose of this study is to find out if rasagiline improves RLS symptoms. We also want to make sure rasagiline is safe to give people with RLS.

Restless Legs Syndrome
Drug: rasagiline
Drug: placebo (sugar pill)

Phase 3

Further study details as provided by University of Virginia:

Primary Outcome Measures:
  • Change in International Restless Legs Syndrome Study Group Rating Scale (IRLS) score from Baseline to Week 12 [ Time Frame: Screening, Baseline, Week 6, Week 12 ]
    The IRLS is a 10-question scale that contains questions about both the frequency and severity of RLS symptoms, as well as secondary aspects such as sleep quality and daytime tiredness.

Secondary Outcome Measures:
  • Tolerability (ability to complete study on assigned dosage) [ Time Frame: 12 weeks ]
  • Adverse events [ Time Frame: 12 weeks ]
  • Change in Beck Depression Inventory from Baseline to Week 12 [ Time Frame: Baseline, Week 6, Week 12 ]
  • Change in Clinical Global Impression - Change from Baseline to Weeks 12 [ Time Frame: Baseline, Week 6, Week 12 ]
  • Change in Medical Outcome Study Sleep Scale from Baseline to Week 12 [ Time Frame: Baseline, Week 6, Week 12 ]
  • Change in Johns Hopkins Restless Legs Syndrome Quality of Life Questionnaire from Baseline to Week 12 [ Time Frame: Baseline, week 6, Week 12 ]
  • Change in Epworth Sleepiness Scale from Baseline to Week 12 [ Time Frame: Baseline, Week 6, Week 12 ]

Enrollment: 52
Study Start Date: September 2010
Study Completion Date: August 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: rasagiline Drug: rasagiline
1mg (2 tablets of 0.5mg) at bedtime taken by mouth for 12 weeks
Other Name: Azilect
Placebo Comparator: placebo (sugar pill) Drug: placebo (sugar pill)
1mg (2 tablets of 0.5mg) taken at bedtime by mouth for 12 weeks

Detailed Description:

The primary objective is to determine if rasagiline, at a dosage of 1mg/day, is non-futile for the treatment of RLS, as measured by the International RLS Study Group Rating Scale (IRLS). The primary outcome variable will be the change in IRLS from baseline to Week 12.

The secondary objectives are to determine if rasagiline, at a dosage of 1mg/day, is safe and well-tolerated in participants with RLS. Also, to determine if rasagiline improves measures of global clinical change, sleep quality, excessive sleepiness, quality of life, or depressive symptoms.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Men and women at least 18 years of age, capable of providing informed consent
  • Diagnosed with idiopathic RLS, defined as meeting the International RLS Study Group diagnostic criteria without evidence for secondary causes of RLS
  • Moderate or severe symptoms, defined as a score of 15 or greater on the International RLS Study Group Rating Scale (IRLS)
  • Not currently receiving treatment for RLS. A 30-day washout period will be required for participants on dopamine agonists or other therapies. Stable doses of iron supplementation will be allowed
  • On a stable dose of the following antidepressants, for at least 30 days prior to baseline visit:

    • Amitriptyline, up to 50mg/day
    • Trazodone, up to 100mg/day
    • Citalopram, up to 20mg/day
    • Escitalopram, up to 10mg/day
    • Paroxetine, up to 30mg/day
    • Sertraline, up to 100mg/day
  • Female subjects must not be of childbearing potential or must agree to use of contraception for duration of study

Exclusion Criteria:

  • Signs consistent with a secondary cause of RLS:
  • History of initial unresponsiveness to dopaminergic RLS treatment despite adequate dose of initial therapy
  • Use of another MAO inhibitor within 30 days of baseline visit
  • Allergy or adverse reaction to rasagiline
  • Prior adverse reaction to tyramine-containing foods
  • Use of meperidine or other opiates within 30 days of the baseline visit
  • Use of benzodiazepines within 30 days of the baseline visit
  • Use of antidepressants, including TCAs, SSRIs, and SNRIs, except for those permitted as listed above
  • Use of other drugs or supplements contraindicated with rasagiline, including St. John's wort, mirtazapine, cyclobenzaprine, dextromethorphan, cold products that contain ephedrine, pseudoephedrine
  • Scheduled to undergo elective surgery during the course of the study
  • Active medical or psychiatric illness that requires changes to treatment during the course of the study or jeopardize the subject's ability to remain in the study
