Active clinical trials for "Parkinson Disease"

To determine the safety and tolerability of repeated dosing with Apomorphine Nasal Powder in subjects with Parkinson's Disease.

Patients with Parkinson's Disease (PD) depend on medication for relief of motor symptoms, and for this reason are often assumed to medicate very carefully. Overall, medication adherence is very good, but a subset of 15 to 20% of cases take less than 80% of the total prescribed dose. However, irregular timing of drug ingestion is almost universal, perhaps contributed by fluctuating symptoms and drug regimen complexity. Pulsatile dopaminergic stimulation in the basal ganglia is implicated in the development and manifestation of motor complications of advancing PD. Irregular medication intake is likely to contribute to peaks and troughs in serum and brain drug levels. In other diseases, patient adherence to prescribed medication improves through simplifying drug regimens, providing additional education, counselling and behavioural approaches and providing reminder packaging. We tested the effect on the timing of medicine ingestion of an educational approach, in which patients were given detailed additional information about the continuous dopaminergic theory.

Parkinson's disease (PD) is a progressive neurodegenerative disease. Symptomatic therapy is primarily aimed at restoring dopamine function in the brain. Oral selegiline in conjunction with L-dopa has been a mainstay of therapy for PD patients experiencing motor fluctuations for many years. The mechanisms accounting for selegiline's beneficial adjunctive action in the treatment of PD are not fully understood. Inhibition of monoamine oxidase (MAO) type B (MAO-B) activity is generally considered to be of primary importance. Oral selegiline has low bio-availability and is typically dosed BID, for a total of 5-10 mg daily. Recently, the FDA approved a new orally disintegration tablet (ODT) formulation of selegiline, called ZelaparTM. This new formulation utilizes Zydis technology to dissolve in the mouth, with absorption through the oral mucosa, thereby largely bypassing the gut and avoiding first pass hepatic metabolism. This allows more active drug to be delivered at a lower dose. Consequently, Zelapar is dosed once-daily, up to 2.5 mg per day. There are no empirical data indicating whether the use of the new approved formulation of selegiline ODT (Zelapar) is superior or preferred by patients compared to traditional oral selegiline. It is believed that clinical efficacy will be preserved or enhanced, by delivering more active drug, with improved patient preference for the ODT formulation due to the once-daily dosing . The effectiveness of orally disintegrating selegiline as an adjunct to carbidopa/levodopa in the treatment of PD was established in a multicenter randomized placebo-controlled trial (n=140; 94 received orally disintegrating selegiline, 46 received placebo) of three months' duration. Patients randomized to orally disintegrating selegiline received a daily dose of 1.25 mg for the first 6 weeks and a daily dose of 2.5 mg for the last 6 weeks. Patients were all treated with levodopa and could additionally have been on dopamine agonists, anticholinergics, amantadine, or any combination of these during the trial. At 12 weeks, orally disintegrating selegiline-treated patients had an average of 2.2 hours per day less "OFF" time compared to baseline. Placebo treated patients had 0.6 hours per day less "OFF" time compared to baseline. These differences were significant (p < 0.001). Adverse events were very similar between drug and placebo.

This is a French national trial, conducted using a double-blind, placebo-controlled, randomised design involving 7 centers and 80 patients of both sexes. The primary objective of the trial is to evaluate the effects of the interruption of a long term treatment (ex. Greater than 6 months) with Amantadine (prescribed as an antidyskinetic) in patients suffering from Parkinson disease being treated with Levodopa and suffering from mid dose dyskinesias. Secondary objectives of the trial are the evaluation of the other effects of withdrawal of Amantadine on the same group of patients: motor fluctuations, vigilance, apathy, fatigue, certain cognitive aspects, the disappearance or development of undesirable side effects and quality of life.

The primary objective of this study is to provide continued access to levodopa-carbidopa intestinal gel (LCIG), to participants who have already participated in an open-label efficacy and safety study with the same treatment (Study S187.3.003 [NCT00360568] or Study S187.3.004 [NCT00335153]).

Parkinson disease is a degenerative neurologic condition characterized by slowness of movement, tremor, and loss of balance control. It results in significant degrees of disability for affected individuals. Exercise and medication management are two treatments frequently used to treat Parkinson disease, and although some individuals benefit from these treatments, by what effect exercise works is presently not known. We will examine muscle structure and movement control responses to strengthening exercises and compare them to the therapeutic response observed as a result of medication intake. This process will allow us to better understand the mechanisms underlying the therapeutic effects of strengthening exercise for persons with Parkinson disease.

This study will evaluate the safety and efficacy of administration of AFQ056 in combination with L-dopa, in reducing the number of L-dopa related dyskinesias in Parkinson's disease patients.

To determine safety, tolerability and preliminary efficacy of intraglandular injections of MYOBLOC for the treatment of sialorrhea in Parkinsons' Disease patients

The REFINE-PD study is a controlled trial embedded within a larger cluster controlled study (the IMPACT study). The study aims to investigate the efficacy of a multifactorial falls prevention program for patients with Parkinson's Disease (PD). This program contains PD-specific elements (e.g., optimizing dopaminergic therapy), plus a generic falls prevention program. The intervention will be tailored to each individual's specific risk profile for falls, as identified during detailed baseline examination.

This is an exploratory study to evaluate if SYN115 has an effect on Parkinson's disease as measured by clinical symptoms and brain images using magnetic resonance imaging (MRI) when a function test is administered.
