Filter by:This is a study of the efficacy and safety of preladenant in adult participants with moderate to severe Parkinson's Disease (PD). While on this study, participants will continue to take their usual, prescribed, stable regimen of levodopa (L-dopa) or L-dopa plus adjunct PD medications and will be randomized to receive 2 mg preladenant, 5 mg preladenant, or placebo, twice daily, for 12 weeks. After that, participants may choose to receive additional treatment with preladenant. The primary hypothesis is that at least the 5 mg twice daily dose of preladenant is superior to placebo as measured by the change from Baseline to Week 12 in the mean "off" time.
The purpose of this study is to document patient outcomes, including effectiveness, safety, and health economic data, for the Boston Scientific implantable deep brain stimulation (DBS) Vercise™ system for bilateral stimulation of the subthalamic nucleus (STN) in the treatment of moderate to severe idiopathic Parkinson's Disease (PD).
The study intends to collect data on gastrointestinal symptoms (swallowing disorders, heartburn, feeling of fullness, nausea, vomiting, abdominal pain, diarrhea) and on patient satisfaction under everyday practice conditions after changing treatment to Neupro® transdermal patch in patients suffering from idiopathic Parkinson´s Disease with gastrointestinal symptoms while being treated with oral antiparkinson drugs. The objective of the study is to ascertain whether switching therapy to Neupro® transdermal patch can provide any relief in gastrointestinal symptoms.
Parkinson's disease is a major neurodegenerative disorder in which there is a progressive loss of nigrostriatal dopaminergic neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO B, the major DA metabolising enzyme in man. This is a double-blind, placebo-controlled, extension trial, parallel-group, randomised, multi-centre, multi national, Phase III trial, comparing two doses of safinamide (50 and 100 mg p.o. q.a.m.) versus placebo as add-on therapy to a stable dose of a single dopamine agonist in subjects with early idiopathic Parkinson's Disease. The principal objective is to evaluate the time to first intervention, as some previous data suggested that safinamide may delay the need for further dopaminergic supplementation.
The objective of this study is to investigate the effect of safinamide on levodopa blood levels, both after single and multiple dosing of safinamide . A further objective of the study is to assess the safety and tolerability of safinamide when given together with levodopa in the applied regimen. For that purpose, all study participants will undergo intensive blood sampling for investigation of levodopa levels and various tolerability examinations, such as the measurement of vital signs (blood pressure, pulse, body temperature), recording of ECGs and questioning to find out how the study participants are feeling. Furthermore, blood samples will be drawn and urine tests will be performed repeatedly for safety purpose during the course of the study. The results of this clinical trial may be used for the drug registration of safinamide in the future.
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.
The purpose of this study was to evaluate the safety and potential benefits of CERE-120 in the treatment of Parkinson's disease.
Medical treatment of idiopathic Parkinson disease motor symptoms requires dopaminergic drugs, with long term disabling side effects. (fluctuations, dyskinesia, ON/OFF phenomena). Use of nicotine in Parkinson's disease has been suggested by the lowest prevalence of smokers among Parkinsonian patients. However, controlled studies provided conflicting results. One of our patients showed a substantial decrease of his parkinsonian symptoms under transdermal nicotine-therapy. Currently, this patient has been treated since 8 years with an excellent safety, especially on cardiovascular level. Otherwise, the investigators performed an open pilot safety and feasibility study in 6 patients, which demonstrated the possibility of a controlled study. In this study, all patients received daily doses during several months until 105 mg/day and could, in parallel, decrease their L-Dopa and agonists doses, improving their motor scores. The investigators now propose a phase II, controlled, single blind and randomised efficacy study (n=40) in 2 parallel groups. (1 group transdermal nicotine-therapy / 1 control group without additional therapy) The main objective is to verify the correlation between UPDRS (score III) motor score and the administrated nicotine dose. This study will also allow the evaluation of nicotine neuroprotective effect. The incrementation phase by weekly steps of 5 mg until 20 mg, then 10 mg to reach 90 mg/j or the maximal tolerated dose, will last on 11 weeks and will be followed by a 28 weeks phase at this stable dose. After this maximal dose "plateau phase", treatment will be progressively decreased by 15 mg weekly steps, over a de 6-week period followed by a five-week wash out phase. Taking into account results from the pilot study, a long-term high doses treatment, seems to be liable to improve patients who deeply suffer from their disease. This is why the investigators now propose this monocentric institutional project.
The aims of the investigators' study are to characterize the nature of constipation in idiopathic Parkinson's disease (IPD) and to evaluate the usefulness of biofeedback therapy in constipated IPD patients.
Parkinson'disease is a neurodegenerative disorder characterised by bradykinesia, rigidity, rest tremor and postural instability. Dopaminergic therapy such as L-Dopa and dopamine agonists usually leads to a dramatic improvement of symptoms, but disease progression nevertheless remains inevitable. Bilateral Deep brain stimulation in subthalamic nucleus is now considered the gold standard surgical treatment. Parkinson'disease mainly affects the nigrostriatal dopaminergic system which is linked to the limbic system and could be responsible of a specific trouble in the recognition in some facial expression. We hypothesise that patients with Parkinson'disease present a dysfunction of voluntary and automatic treatment of emotional information. The main purpose of this study is to show if patients with Parkinson'disease present a lack of specific facial expression recognition of emotion and determinate more precisely if this alteration involves the cortical way (high frequency way) or the under cortical way (low frequency way). We also examine the role of L-Dopa and the deep brain stimulation on emotion perception
