INfusion VErsus STimulation in Parkinson's Disease

Parkinson's Disease

Both Continuous intrajejunal Levodopa Infusion (CLI) and Deep Brain Stimulation (DBS) are accepted therapies for the treatment of advanced Parkinson's disease (PD). To date, no comparative studies have been executed. The INVEST study is an open label randomised controlled trial with cost-effectiveness as primary outcome. The main clinical outcome is quality of life; secondary outcomes are motor symptoms and neurological impairments, among others.

Cont. of a Study to Evaluate Implanting Peripheral Nerve Grafts Into Subjects With Parkinson's Disease...

Parkinson's Disease

This pilot study is designed to follow up on a previous, preliminary study and test the long-term safety and feasibility of the implantation of autologous peripheral nerve grafts into the substantia nigra, basal forebrain, putamen, and/or STN of participants with PD undergoing deep brain stimulation (DBS) surgery. Peripheral nerve tissue contains Schwann cells which produce growth factors that have been demonstrated to support the survival and function of neurons. Participants will serve as their own donor for the tissue, which will be implanted at the time they undergo DBS surgery.

Aerobic Exercise in Parkinson's Disease

Parkinson's Disease

Parkinson's disease (PD) is an incurable brain illness that afflicts more than one million Americans, including many aging Veterans. PD places an unbearable burden on the individual due to progressive impairment of movement and mental function. As a result, patients lose critical abilities such as driving and can become isolated. Although drugs and surgery help movement problems, their benefits are temporary and may cause side effects. Drugs provide limited and temporary benefit for cognition and do not prevent dementia. Animal and preliminary human studies on aerobic exercise show promising results in helping a broad spectrum of symptoms. However, due to limited and inconsistent research results, the long term effects of aerobic exercise on brain health and clinical features in PD is unknown. The investigators will conduct a clinical trial to test the long term effects of aerobic exercise on the brain tissue, movement, mental functions, and driving in PD. If effective, aerobic exercise can be implemented immediately as a low cost, easily accessible treatment in PD.

Benefits of Mild Body Exercises in Parkinson's Disease

Parkinson Disease

The purpose of this study is to learn the effects of two mild body exercises on quality of life, non-motor symptoms, anxiety, depression, fatigue, sleep quality, cognition, and executive function on people with Parkinson's Disease (PD).

A Study to Evaluate the Efficacy of Prasinezumab (RO7046015/PRX002) in Participants With Early Parkinson's...

Parkinson's Disease

This multicenter, randomized, double-blind, placebo-controlled, Phase 2 study will evaluate the efficacy of intravenous prasinezumab (RO7046015/PRX002) versus placebo over 52 weeks in participants with early Parkinson's Disease (PD) who are untreated or treated with monoamine oxidase B (MAO-B) inhibitors since baseline. The study will consist of three parts: a 52-week, double-blind, placebo-controlled treatment period (Part 1) after which eligible participants will continue into an all-participants-on-treatment blinded dose extension for an additional 52 weeks (Part 2). Participants who complete Part 2 (including the 12-week treatment-free follow up visit assessing long term safety and efficacy of RO7046015) will be offered participation in Part 3 open-label extension (all-participants-on-RO7046015-treatment) for an additional 260 weeks.

Stimulation of the Rostral Zona Incerta for Parkinson's Disease

Parkinson Disease

Patients with Parkinson's Disease who undergo Deep Brain Stimulation surgery receive symptom relief due to electrical stimulation of the brain. The target for the stimulation, in many cases, is the subthalamic nucleus (STN). The brain area just above the STN is called the rostral Zona Incerta (rZI). The rZI may be a potential target for deep brain stimulation, in combination with the STN.

Adaptive Deep Brain Stimulation to Improve Motor and Gait Functions in Parkinson's Disease

Parkinson Disease

This is a single-center phase I clinical study aiming to improve gait functions in patients with Parkinson's disease (PD) by using adaptive neurostimulation to the pallidum. The investigators will use a bidirectional deep brain stimulation device with sensing and stimulation capabilities to 1) decode the physiological signatures of gait and gait adaptation by recording neural activities from the motor cortical areas and the globus pallidus during natural walking and a gait adaptation task, and 2) develop an adaptive deep brain stimulation (DBS) paradigm to selectively stimulate the pallidum during different phases of the gait cycle and measure improvements in gait parameters. This is the first exploration of network dynamics of gait in PD using chronically implanted cortical and subcortical electrodes. In addition to providing insights into a fundamental process, the proposed therapy will deliver personalized neurostimulation based on individual physiological biomarkers to enhance locomotor skills in patients with PD. Ten patients with idiopathic Parkinson's disease undergoing evaluation for DBS implantation will be enrolled in this single treatment arm study.

Exenatide Once Weekly Over 2 Years as a Potential Disease Modifying Treatment for Parkinson's Disease...

Parkinson's Disease

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).
