Active clinical trials for "Parkinson Disease"

Patients with Parkinson's disease are missing the chemical neurotransmitter dopamine. This occurs as a result of destructive changes in an area of the brain responsible for making dopamine, the basal ganglia. Muscle tremors, rigidity of movement, shuffling footsteps, droopy posture, and a mask-like expression on the face characterize Parkinson's disease. This study is designed to determine the effects of a new drug, N-9023. The drug acts like dopamine and can be given through a skin patch (transdermal) for treatment of parkinsonian symptoms. The goals of this study are to find out whether N-9023 is useful in treating the signs and symptoms of Parkinson's disease and to determine the best dose of N-9023 that is safe and effective.

The purpose of this study is to confirm that the dose levels and dosing frequency utilising the new Stalevo strengths would result into more stable levodopa plasma levels. Therefore, it is anticipated that when lower dose of Stalevo is administered after the first higher dose of Stalevo, this would result in equally high levodopa maximum concentration values (Cmax) after each dose throughout the day compared to Cmax after the first dose.

The study hypothesis is that continuous ND0611 increases the bioavailability of levodopa and therefore the levodopa area-under-the-concentration-curve values, half-life, and trough concentrations The study will help determining the safety and tolerability of ND0611 and determine the pharmacokinetic profile of levodopa following multiple oral dosing of levodopa/carbidopa (LD/CD) and continuous delivery of ND0611

The purpose of this study is to evaluate the safety and efficacy of 40 mg pimavanserin compared to placebo in patients with Parkinson's disease psychosis (PDP).

Patients with Parkinson's disease who completed the prior double-blind study 6002-009 are eligible to enter into this long-term study. The purpose of this study is to evaluate the safety and efficacy of KW-6002 administered long-term in patients with advanced Parkinson's disease treated with levodopa.

The purpose of this clinical trial is to investigate the effects of the non-ergot dopamine agonist piribedil on vigilance and cognitive performances in patients with Parkinson's disease in comparison with other oral non-ergot dopamine agonists. It should be tested whether piribedil is superior to continued pramipexole or ropinirole treatment regarding improvement of reduced vigilance and cognitive performance in patients with Parkinson's disease.

Dysphagia in Parkinson's disease(PD) is common and its presence is related to motor and sensory abnormalities, and incoordination between swallowing and breathing. Despite harming as respiratory infections and increased risk of death, treatment of this condition remains uncertain. This study aims to evaluate the effect of oral motor exercises on the swallowing dynamics and quality of life of dysphagic Parkinson's disease patients. This study is an open trial, self-paired and blinded to the examiner. The participants will perform oropharyngeal exercises for five weeks and will be evaluated before and after intervention by swallowing videofluoroscopy and questionnaires about quality of life in dysphagia (SWAL-QOL).

This is an open-label study to investigate the effects of the rivastigmine patch on attention and behavior in Parkinson's disease when associated with memory and/or thinking problems. Rivastigmine (also sold under the name Exelon) is an FDA approved medication used for the treatment of mild to moderate Alzheimer's Disease (AD) and memory or thinking problems due to Parkinson's disease. Recently a rivastigmine patch was developed, which has shown similar effectiveness with fewer side effects and increased caregiver preference when compared to capsules. This is an open-label 12 week study where 15 subjects diagnosed with Parkinson's Disease who have mild to moderate memory and/or thinking complaints will be treated with the rivastigmine patch at UCSF. This study also analyzes the mechanism by which the rivastigmine patch works in people with Parkinson's disease and memory and/or thinking problems.

This phase IIb study is designed to determine the safe and efficacious dose or dose range of AFQ056 for the treatment of patients with moderate to severe Parkinson's disease with L-Dopa induced dyskinesias.

Motivated by reported improvements in aerobic fitness and executive functions after a 6-month aerobic walking intervention in normal sedentary elderly, we conducted a Phase I/II study to investigate effects of aerobic exercise on motor function, cognition, and quality of life in mild-moderate patients with Parkinson's disease (PD). To identify the best method to deliver fitness training, we also aimed to compare safety, tolerability, and fitness benefits between different training methods (continuous/moderate intensity vs. interval/alternating between low and vigorous intensity) and exercise settings (individual vs. group). Interval training reportedly facilitates higher fitness gains than continuous training. Group training may promote success through social interaction, whereas individual training offers greater flexibility.
