Active clinical trials for "Dyskinesias"

This is a multicenter, randomized, double blind, pramipexole-controlled parallel group study of pardoprunox as adjunctive treatment to levodopa.

The primary objective of this study is to determine whether intramuscular injections of botulinum toxin type A (Botox®) in selected cervical muscles at antidystonic dosages can reduce levodopa-induced peak-dose dyskinesias (LID) in the cervical region in adult patients with idiopathic Parkinson's disease. It is hypothesized that the intramuscular injection of antidystonic doses of botulinum toxin into cervical muscles will decrease the duration and severity of LID in the cervical region in patients with Parkinson's disease (PD).

Tennis is a sport where high performance, strokes and wide ranges of motion around the court must be created and high-strength movements are repeated repeatedly. Speed and control are important in terms of sportive performance during the serve throw in tennis. While these actions are taking place, a dynamic load that exceeds the physiological limits of the joint is placed on the shoulder. Disruption in the kinetic chain can cause injury to the shoulder. In this regard, the incidence of tennis injuries is approximately 21.5 injuries per 1000 training hours. The glenohumeral joint creates a wide range of motion for the shoulder and is also biomechanically related to the scapula. Scapular dyskinesia, the pathological position of the scapula, has been associated with common pathologies such as rotator cuff tears, labral tears, and shoulder impingement. Although there are studies with different opinions about the causality of scapular dyskinesia, the current literature has reported that scapular dyskinesia is indirectly associated with shoulder pain in overhead athletes. Achieving maximum shoulder performance in sports that require overhead activities such as tennis largely depends on the delicate balance between the scapula and the clavicle, humerus and rib cage joints. Tennis, which is an increasingly widespread sport in our country, exposes the shoulder joints to high stresses. If changes are not detected and necessary precautions are not taken, the shoulder structure may be at risk of injury. In the current literature review, no study was found that evaluated the relationship between scapular dyskinesia, shoulder mobility and serving speed in tennis players. The aim of our study is to evaluate the effects of scapular dyskinesia, glenohumeral joint mobility and posterior capsule tension on serving speed in tennis players. It is thought that the results to be obtained from our study will guide the creation of appropriate exercise programs in athlete training by determining the effects on sportive performance by determining the changes seen or to be seen in the shoulder complexes of tennis athletes.

This Phase 3b, rollover study will provide participants who completed a Phase 3 valbenazine (NBI-98854) study open-label access to valbenazine (fixed doses administered once daily) for the treatment of adults with TD until valbenazine is anticipated to be available commercially or they complete 72 weeks of treatment. This study will allow enrollment of up to 150 medically stable male and female participants with TD who previously participated in and completed the NBI-98854-1304 (Kinect 3) or NBI-98854-1402 (Kinect 4) Phase 3 study.

Parkinson's disease (PD) is one of the most common neurodegenerative diseases, with a higher prevalence in the elderly. Levodopa induced dyskinesias (LID) are a major motor complications that impair quality of life for patients with PD. The mechanisms of these dyskinesias remain unclear, but several hypotheses have been put forward: non continuous, pulsatile stimulation of dopaminergic receptors, or alterations of other neurotransmitters within the motor striatum such as glutamate and serotonin. Few strategies are now available to treat severe LID: Medications: reduction of dopaminergic treatment, addition of amantadine, Functional neurosurgery. The purpose of this study is to investigate the efficacy of buspirone in PD patients suffering from dyskinesias. The role of serotonin in the occurrence of LID was recently demonstrated in transplant PD patients and a test double-blind, single dose was achieved. Following administration of 10 mg oral buspirone, a 5HT1A agonist, LID were clearly improved. A antidyskinetic effect of buspirone had already been reported in 1991 and 1994, but identification of buspirone as a serotonin receptor agonist has been reported more recently. This trial is aimed at (1) validate the serotoninergic hypothesis of hyperkinetic levodopa induced dyskinesias (LID) in Pakinson's disease patients, (2) evaluate, in a phase 3 trial, the motor efficacy of buspirone to improve LID vs placebo, (3) look at a possible dose/effect relationship and (4) check the hypothesis of a better therapeutic ratio using the association of buspirone and amantadine instead than a single drug.

Purpose: Tardive dyskinesia (TD) is a involuntary movement disorder that can occur following long term treatment with antipsychotic medications and for which few treatment options exist. This study will test the efficacy of pyridoxine (also known as vitamin B6) for TD. This will be an 8 week double-blind, placebo-controlled, randomized trial measuring the effect of pyridoxine 400 mg/day on the severity of involuntary muscle movements in people who meet Schooler-Kane criteria for TD. Participants: Approximately 50 subjects will be recruited from the UNC Schizophrenia Treatment and Evaluation Program (STEP) and other local psychiatric clinics. Procedures (methods): Symptoms of TD will be assessed using the Abnormal Involuntary Movement Scale (AIMS). Pharmacological Intervention: All participants who meet entry criteria will be randomized to one of two treatment groups: pyridoxine or placebo.

CP (cerebral palsy) refers to a group of neurological disorders that appear in infancy or early childhood and permanently affect body movement and muscle coordination. CP is caused by damage to or abnormalities inside the developing brain that disrupt the brain's ability to control movement and maintain posture and balance. The signs of CP usually appear in the early months of life, although specific diagnosis may be delayed until the age of 2 years or older. TEV-50717 (deutetrabenazine, also known as SD-809) has already provided evidence for safe and effective use in 2 other hyperkinetic movement disorders, namely chorea in Huntington's disease (HD) and tardive dyskinesia (TD). Currently, there is no approved treatment available for Dyskinesia in cerebral palsy (DCP). The available treatment options address some of the manifestations of DCP. The study population will include pediatric and adolescent participants (6 through 18 years of age) with DCP with predominant choreiform movement disorder, who have had nonprogressive CP symptoms since infancy (≤2 years of age). Diagnosis of DCP is based on the Surveillance of Cerebral Palsy in Europe criteria. This is a Phase 3 study that will evaluate the efficacy and safety of TEV-50717 administered as oral tablets at a starting dose of 6 mg once daily in participants (age 6 through 18 years, inclusive) with DCP with predominant choreiform movement disorder. The study will be conducted in multiple centers and will use 2 parallel treatment groups (ie, TEV-50717 and placebo) in which participants will be randomized in a 2:1 ratio. "Predominant" in this instance indicates that the choreiform movement disorder is the main cause of impairment or distress.

This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance. In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.

The proposed study is to evaluate the safety and initial effectiveness of the ExAblate Transcranial MRI-guided focused ultrasound (MRgFUS) treatment of patients with dyskinesia of Parkinson's Disease (PD) Safety: To evaluate the incidence and severity of adverse events (AE/AEs) associated with ExAblate Transcranial MRgFUS treatment of dyskinesia of PD Effectiveness: To determine the level of effectiveness of the ExAblate Transcranial MRgFUS treatment of dyskinesia of PD.Efficacy will be determined utilizing the UPDRS-IV for dyskinesia in PD from examinations at baseline and every 3-Months post-ExAblate treatment. This study is designed as a prospective, single-site, single arm, nonrandomized study. Assessments will be made before and three months after MRgFUS for clinical symptom relief, quality of life (QoL) improvements, and safety of MRgFUS in the treatment of LID. Relative Safety will be evaluated using a common description of Significant Clinical Complications for patients treated in this study. This study will be performed on the 3T MR scanners.

To evaluate the efficacy, safety, and tolerability of AVP-923 capsules containing 45 mg dextromethorphan and 10 mg quinidine (AVP-923-45) compared to placebo for the treatment of levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD).
