Filter by:This study is a clinical trial in patients with Parkinson's disease (PD), of a drug called exenatide, which is already licensed for the treatment of patients with type 2 diabetes. There have been several groups that have confirmed that exenatide has beneficial effects of nerve cells when tested in the laboratory, which raises the possibility that exenatide may slow down or stop the degeneration of PD. In an open label trial in patients with PD who self administered the drug for a period of 48 weeks, the investigators have previously shown that the drug is well tolerated and shows encouraging effects on the movement and non-movement aspects of the disease. A double blind placebo controlled trial involving 60 participants was then conducted which indicated that exenatide may be a "neuroprotective" drug, i.e. one that stops the nerve cells dying in PD. The next step is therefore to confirm this "neuroprotective" effect and to see whether this effect can be reproduced in a multi-centre setting including a larger number of participants. An important objective is to explore whether any positive effects remain static or increase when the treatment is continued over a 96 week period. In order to explore this, a randomised, double blind, parallel group, placebo controlled, Phase 3 trial of Exenatide is being undertaken (Exenatide-PD3).
In this longitudinal study, the investigators will follow Parkinson's disease (PD) patients with and without glucocerebrosidase (GBA) mutations. The investigators hypothesize that the rate of increase in brain network activity over time (network progression rate) is faster in patients with GBA gene mutations.
There are experimental evidences of the important role of high intensity physical exercise in Parkinson's disease (PD) treatment, that induces similar effects to pharmacotherapy. So far, the mechanisms of the impact of these changes on the brain subcortical and cortical regions functioning, motor activities and cognitive functions are still not clear. The aim of this longitudinal (prospective) human experiment is to examine the effects of two cycles of 12-weeks high-intensity interval training (HIIT) on: (i) the level of dopamine (DA) in putamen in striatum, (ii) neurophysiological function of subcortical and cortical motor structures and skeletal muscle activity, (iii) psychomotor behaviors critically associated with dopamine dependent neural structures functioning and (iv) neurotrophic factors' secretion level in blood. The investigators will recruit 40 PD individuals, who will be divided into two groups: one of them will perform two 12-weeks cycles of HIIT (PD-TR), and the other will not be trained (PD-NTR) with HIIT. The investigators will also recruit 20 age-matched healthy controls (H-CO) as additional control group who will not perform the HIIT. The PD-TR group will perform the two 12-weeks cycles of the HIIT, that induces beneficial, neuroplastic changes and alleviates the PD symptoms, what was found in earlier studies. All PD subjects (PD-TR and PD-NTR) will be examined during their medication "OFF-phase" (it means after dopaminergic drugs withdrawal) before (Pre) and after (Post) training cycles (first training cycle - HIIT 1; second training cycle - HIIT 2), and namely: Pre HIIT 1, 1 week-, 1.5 month- and 3 months-Post HIIT 1; and then similarly 1 week-, 1.5 month- and 3 months-Post HIIT 2. The subject from H-CO will be tested only once. To examine the assumed HIIT-induced changes in brain functioning the investigators will apply: (i) the positron emission tomography (PET), (ii) the functional magnetic resonance imaging (fMRI), (iii) electroencephalography (EEG) and (iv) an analysis of neurotrophic factors secretion level in blood. The investigators will also assess motor and non-motor symptoms of PD and psychomotor behaviors based on neuropsychological tests of cognitive functions and manual dexterity. The results of this project will help to answer the fundamental questions about HIIT induced mechanisms of neuroplasticity in PD patients, what is important from scientific and treatment-strategy point of view.
PARKINSUN is a new communication aid tool, expected to favor global patient centered care for PD patients during consultation with GPs and neurologists. Two groups of patients will be randomized to use or not PARKINSUN when they consult their physicians every 3 months during 7 months.
The objective of this Phase 1b investigation is to evaluate the safety and potential clinical effect of AAV2-GDNF delivered to the putamen in subjects with either a recent or a long-standing diagnosis of PD.
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of oral doses of FB-101 in healthy subjects.
This is a pilot study to explore the effects of pimavanserin and low-dose quetiapine in subjects with Parkinson's disease with neuropsychiatric symptoms.
The Recreation Therapy Wellness Recovery Program conducts group classes which provide repetitive training of foundational skills designed specifically for those with Parkinson's Disease. The course will encourage bigger and faster movements (adapted from the Parkinson Wellness Recovery, PWR!Moves ® program) and education on optimal function.
This study will be conducted in subjects with established Parkinson's disease in 2 parts. Part A will examine the tolerability, safety, and pharmacokinetics of AZ-009 dose escalation ; and Part B will assess the tolerability, safety, pharmacokinetics, and pharmacodynamics of AZ-009 compared with placebo in a crossover design
This study will evaluate the safety and tolerability of ABBV-0805 in adult participants with Parkinson's Disease and results from it will help guide the design of future clinical studies. ABBV-0805 is administered every 28 days by intravenous (IV) infusion.
