Safety and Efficacy of Rasagiline in Restless Legs Syndrome

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.

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

- History of initial unresponsiveness to dopaminergic RLS treatment despite adequate
dose of initial therapy
