Active clinical trials for "Parkinson Disease"

The investigators will modify and evaluate the feasibility of a mindfulness intervention among people living with Parkinson disease (PD) and freezing of gait (FOG). FOG is a severe motor disturbance that prevents people from stepping normally and is associated with anxiety, frustration, sedentary behaviors, poorer quality of life, and falls. Mindfulness-Based Stress Reduction (MBSR) is an evidence-based practice that creates a culture to reduce stress and anxiety by increasing conscious awareness and self-compassion. In this study, the investigators will develop a mindfulness-based walking intervention to address both mental health and mobility challenges that constitute FOG. This R34 feasibility study includes three aims to permit the development of a mind and body approach for FOG among people living with PD.

NR-SAFE is a double-blinded randomized safety study aiming to determine the safety and tolerability of nicotinamide riboside (NR) at a daily dose of 3000mg, in individuals with Parkinson's disease (PD). The investigators recently reported the results of the NADPARK study (ClinicalTrials.gov: NCT03816020), a phase I randomized, double-blinded trial, assessing the tolerability, cerebral bioavailability and molecular effects of NR therapy, 1000mg daily, in PD. The NADPARK study showed that NR 1000mg daily was well tolerated and led to a significant, but variable, increase in cerebral NAD levels (measured by 31phosphorous magnetic resonance spectroscopy, 31P-MRS) and related metabolites in the cerebrospinal fluid (CSF). NR recipients showing increased brain NAD levels exhibited altered cerebral metabolism, measured by 18fluoro-deoxyglucose positron emission tomography (FDG-PET), and this was associated with mild clinical improvement. The results of the NADPARK trial nominate NR as a potential neuroprotective therapy for PD, warranting further investigation in larger trials. It is plausible that any beneficial effects of NR in PD may be dose-dependent and more pronounced at higher doses. NR doses of up to 2000mg daily have been tested in healthy humans with no signs of toxicity. However, the safety and tolerability of even higher doses is untested. To enable clinical studies assessing higher doses, the investigators will assess the safety and tolerability of an oral dose of 3000 mg NR daily. NR-SAFE will recruit 20 participants with PD and randomize them 1:1 to either NR 3000mg daily or placebo for a total duration of 4 weeks.

The purpose of the study is to assess the safety, tolerability, and pharmacokinetics of single, ascending doses of ABBV-951 administered as a subcutaneous bolus infusion followed by a continuous subcutaneous infusion in subjects with Parkinson's disease.

Objective: To verify the effectiveness of chin-down posture maneuver in swallowing therapy for Parkinson's disease (PD).

This study assesses the safety, tolerability, pharmacokinetics and efficacy of SAGE-217 in 29 participants with moderate to severe Parkinson's Disease.

The purpose of this study was to investigate the effect on the "wearing-off" phenomenon of 3 different doses of nebicapone (NEB 50 mg, 100 mg and 150 mg), compared with entacapone and placebo when dministered concomitantly with existing treatment with levodopa plus a dopa decarboxylase inhibitor (DDCI: carbidopa or benserazide).

Evaluation of the effectiveness of aquatic therapy for the treatment of freezing of gait in Parkinson's disease patients undergoing a multidisciplinary and intensive rehabilitation treatment.

This is a phase IIa, first in human, randomized, double-blind, multicenter study to evaluate the safety, tolerability and efficacy of DA-9805 at 45mg, 90mg versus placebo in subjects diagnosed with early Parkinson's disease.

This study will explore the effects of 3 different neurostimulation methods on swallowing function in patients with dysphagia secondary to Parkinson's Disease

Prospective trial of low frequency deep brain stimulation of the ventral subthalamic nucleus to improve cognitive performance in patients with advanced Parkinson's disease. All study participants have undergone DBS implantation surgery as part of their routine care for motor manifestations of Parkinson's disease. In this study, a temporary low frequency period of stimulation will be applied to determine its effects on cognition.
