Active clinical trials for "Restless Legs Syndrome"

Tyrosine is a non essential amino acid that is the precursor of the neurotransmitter, dopamine. Tyrosine is converted into Levodihydrophenylalanine (L-Dopa) and L-Dopa is subsequently and avidly converted into dopamine. It is well known that dopamine deficiency leads to the manifestations of restless legs syndrome (RLS). Studies have shown dopamine agonists and L-dopa to be effective in controlling symptoms. No studies to date have been done to determine the role of tyrosine in RLS. This open-label pilot study aims to determine the efficacy and tolerability of tyrosine in RLS, as current agents have limitations in treating RLS in addition to adding another possible agent to the investigators arsenal of treating RLS that maybe more cost efficient. In this pilot study, the dose of tyrosine will be escalated from 750 mg once daily by mouth (PO) up to 3000 mg once daily PO, as tolerated, in increments of 750 mg every week in patients who meet the inclusion criteria for RLS. Patients' symptoms will be monitored on a weekly basis for six weeks.

The purpose of this study is to assess the efficacy and safety of GSK1838262 extended release tablets in the treatment of patients with Restless Legs Syndrome and associated sleep disturbance.

The purpose of this study is to determine if bupropion will improve the symptoms of restless legs syndrome (RLS).

The purpose of this study is to evaluate the efficacy and safety of cabergoline compared with placebo on periodic leg movements (PLMS) arousl index and sleep efficiency in patients with RLS. Also, additional objective and subjective sleep parameters and quality of life will be assessed.

This study in RLS patients is designed to assess the affect food has on the absorption, distribution, metabolism and excretion of ropinirole (by dosing some patients in the fasted state and other patients following a high-fat breakfast), and to assess the difference in absorption, distribution, metabolism and excretion of ropinirole if patients are given two 3mg ropinirole tablets versus one 6mg tablet.

To define the effective dose and tolerability of levetiracetam in individuals with Restless Legs Syndrome (RLS). It is hypothesized that levetiracetam will be well tolerated, safe and effective in treating the symptoms of RLS.

To demonstrate the superiority of ASP8825 over placebo and the dose response in patients with restless legs syndrome

A 14-Week clinical research study to compare the effectiveness and safety of ropinirole and placebo (an inactive sugar pill) in the treatment of patients with Restless Legs Syndrome (RLS) in the United States.

The primary objective of this trial is to assess the maintenance of efficacy of gabapentin enacarbil (GEn, XP13512) taken once daily in the long-term treatment of patients suffering from Restless Legs Syndrome (RLS).

The primary objective is to assess sustained efficacy in patients who have responded to a 6 month treatment with open-label pramipexole. Secondary objectives are the measurement of severity of the RLS, assessment of early withdrawal phenomena after termination of trial medication, augmentation under treatment, sleepiness, quality of life and subjective wellbeing, the physician's clinical assessment of symptom severity and improvement. Another secondary objective is safety and tolerability of treatment.
