Active clinical trials for "Restless Legs Syndrome"

The purpose of this study was to evaluate the efficacy and safety of different doses of pramipexole (Sifrol) on subjective and objective symptoms of idiopathic Restless Legs Syndrome (RLS) and also to determine the optimal dose of pramipexole in patients with RLS by polysomnography and evaluation of clinical improvement.

A 12-week clinical research study to evaluate the tolerability, efficacy and safety of ropinirole compared to placebo(an inactive sugar pill) in the treatment of patients with RLS in the United States.

Subjects who meet the diagnosis of idiopathic restless legs syndrome (RLS) based on the 4 cardinal clinical features according to the International Restless Legs Syndrome Study Group (IRLSSG) are allowed to enroll in this trial. The primary objective of this trial is to demonstrate that rotigotine (SPM 936) is efficacious in subjects with idiopathic restless legs syndrome. Additional objectives are to investigate the safety and tolerability of rotigotine. Subjects will be randomized to receive either placebo, 1.125, 2.25, 4.5, or 6.75mg/day rotigotine in a 1:1:1:1:1 (active:placebo) fashion. Approximately 600 subjects will be enrolled in this trial, participating at approximately 60 sites. The maximum duration of the trial is approximately 8 months (consisting of a 4-week Titration Period, a 6-month Maintenance Period, a 7-day Taper Period, and a 30-day Safety Follow-Up Period).

A 12 week clinical trial was conducted in the United States in order to compare pramipexole (Mirapex®) versus placebo for the ability to reduce the symptoms of restless legs syndrome in adult subjects.

The objective of this study was to assess the single dose bioequivalence of Roxane's Ropinirole Tablets, 0.25 mg to ReQuip Tablets, 0.25 mg (GlaxoSmithKline) under fasting conditions using a single-dose, randomized, 2-treatment, 2-period, 2-sequence cross-over design.

Non-randomized open label Phase II clinical trial in which subjects meeting criteria for RLS were assigned to 1 of 3 treatment cohorts. The first cohort received one 500 mg IV iron sucrose infusion in 500 mL normal sterile saline (NSS) administered over four hours. The second cohort received two 500 mg IV iron sucrose infusions in 500mL of NSS administered over four to six hours on two separate dates, separated by two to seven days. The third cohort received two 500 mg IV iron sucrose infusions in at least 500 mL of NSS over six hours within 30 hours of the start of the first infusion. Cohorts were enrolled and treated subsequently.

The objective of this study was to assess the single dose bioequivalence of Roxane's Ropinirole tablets,0.25 mg, to ReQuip Tablets, 0.25 mg (GlaxoSmithKline) under fed conditions using a single dose, randomized, 2-treatment, 2-period, 2-sequence cross-over design.

Several studies report association between restless legs syndrome (RLS), HTA and cardiovascular diseases . The mechanisms involved in this relationship remained unknown, but several evidences favor the role of periodic limb movements in sleep (PLMS), patterns frequently associated with RLS. Sympathetic overactivity is associated with PLMS with increased pulse rate and blood pressure coincident with PLMS. PLMS-related repetitive nocturnal blood pressure fluctuations could contribute to the risk of high blood pressure, heart disease, and stroke in patients with RLS, especially in the elderly. Several studies already reported that dopaminergic agonists reduce the severity of RLS and the PLMS index. Do dopaminergic agonists reduce the risk of cardiovascular diseases and associated autonomic dysfunctions in patients with RLS ? Nocturnal BP (blood pressure) decline has major clinical implications, and the loss of normal reduction in BP during sleep is associated with high risk of cardiovascular morbidity and mortality. The main aim of this study was to evaluate the impact of rotigotine patch treatment on validated cardiovascular risk factors ambulatory BP during night, day and night-to-day ratio, and endothelial function in patients with idiopathic RLS compared to placebo.

Objective: Obstructive sleep apnoea syndrome (OSAS) is a common form of sleep-disordered breathing (SDB) causing sleep fragmentation, daytime sleepiness, cognitive function impairment, and poor health status in addition to increased risk of cardiovascular complications. OSAS is equally common among the middle-aged male Caucasian and Hong Kong (HK) Chinese populations with a prevalence of at least 4%. However, the prevalence of OSAS in the elderly population in Asia including HK is unknown. Study Design: A sleep questionnaire will be conducted for 1000 subjects aged at least 60 yrs in the elderly community centers focusing on symptoms of OSAS, subjective sleepiness, restless leg syndrome, and sleep-related habits and routines, in addition to past medical history and medications. Home sleep study (EMBLETTA) capable of recording sleep (a single EEG channel), respiratory events, snoring, respiratory efforts and oximetry will be performed on 300 subjects randomly. Those who have negative or technical inadequate EMBLETTA study with a high pre-test probability of moderate to severe OSA will be invited to undergo hospital-based polysomnography for confirmation of their sleep apnoea status. Subjects with AHI>15/hr regardless of symptoms or those with AHI 5-15/hr plus comorbid conditions or excessive daytime sleepiness will be offered continuous positive airway pressure (CPAP) titration followed by CPAP treatment, with serial assessment of subjective sleepiness, quality of life, and cognitive function. Outcome measures: the prevalence rates of SDB (AHI>10, >15 and >30/hr), OSAS, and other sleep disturbances, such as restless leg syndrome (RLS). In addition, we will examine the factors which are predictive of the presence of SDB in this population, and assess the CPAP acceptance, compliance, and treatment outcome of those with OSAS.

The primary objective of the study is to determine whether Butrans Transdermal System (BTDS) reduces RLS symptom severity in patients with moderate to severe idiopathic RLS who are naïve to opiate treatment. The secondary objective of the study is to investigate the effects of BTDS on mood, sleep, and quality of life. The study will consist of nine visits. Depending on the need for medication titration, there may also be two scheduled telephone contacts. Visit 1: This is a screening visit to determine study eligibility. Eligible subjects who choose to participate must undergo medication washout as described in the detailed protocol between visits 1 and 2. Treatment period #1 (Visits 2 - 5; day 0 - 28): Baseline measures will be recorded and subjects randomized to treatment order at visit 2 (day 0). Study medication as well as rescue medication (l-dopa, a non-blinded active treatment to be used within a limited dose range as described in the detailed protocol) will be dispensed. Subjects will begin treatment period #1 immediately after this. The study medication will be titrated within the allowed range according to subject's reported symptoms during visit 3 (day 7), visit 4 (day 14), telephone contact (day 21). Visit 5 will occur on day 28 and will include assessment of outcome measures for the first treatment period. Visit 5 will also mark the beginning of the second treatment period. Treatment period #2 (Visits 6 - 8; day 28 - 56): Procedures will be similar to those described above during treatment period #1. Visit 8 will mark the end of the second treatment period during which outcome measures will be ascertained. Follow up visit (Visit 9; day 70): This will be a safety follow-up visit approximately two weeks after visit 8 for review of adverse events.
