  • BIIB122 Tablets and if it Can Slow the Worsening of Early-Stage Parkinson's Disease in Participants Between the Ages of 30 and 80

    open to eligible people ages 30-80

    In this study, researchers will learn more about a study drug called BIIB122 in participants with early-stage Parkinson's disease (PD). In this study: - Participants will take 225 milligrams (mg) of BIIB122 or a placebo as tablets by mouth. A placebo looks like the study drug but has no real medicine in it. - Participants will take BIIB122 or placebo 1 time a day for up to a minimum of 48 weeks and a maximum of 144 weeks. - Certain medications for PD will be allowed at enrollment for a subset of participants. - Participants will have to visit at 2-week intervals between baseline and week 12 and at 4-week intervals between week 12 and week 48 and at 12 week intervals between week 48 and week 144. The main question researchers are trying to answer is if taking BIIB122 slows the worsening of symptoms more than placebo in the early stages of PD. To help answer this question, researchers will use a questionnaire called the Movement Disorder Society-Unified Parkinson's Disease Rating Scale, also known as the MDS-UPDRS. Researchers will use the MDS-UPDRS to learn about participant PD symptoms and how they affect their daily life. Researchers will also learn more about the safety of BIIB122.

  • Blood Pressure Effects on Cognition and Brain Blood Flow in PD

    open to eligible people ages 50 years and up

    Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Besides causing symptoms that impair movement, PD also causes non-motor symptoms, such as problems thinking and orthostatic hypotension (OH), i.e., low blood pressure (BP) when standing. About one-third of people with PD have OH, which can cause sudden, temporary symptoms while upright, including lightheadedness, dizziness, and fainting. People with PD and OH can also experience problems thinking that happen only while upright and not while sitting - this can occur without other symptoms, such as feeling dizzy or faint. However, the level of low BP that can affect thinking remains unknown, and no guidelines exist for treating OH when it happens without symptoms. This is significant because OH could be a treatable risk factor for thinking problems in PD, but OH is often not treated if people do not report obvious symptoms. This project's goal is to determine how BP affects brain function in PD. The proposed experiments will measure BP and brain blood flow continuously in real-time using innovative wearable technology. Persons with PD with OH and without OH will undergo repeated cognitive tests while supine (lying down) and while upright. I will study the associations between BP, thinking abilities, and brain blood flow, and will compare groups with and without OH. These findings could be important because if a certain level of BP correlates with thinking abilities, then treating OH in PD may prevent thinking problems, which would improve health-related quality of life and reduce disability and healthcare costs.

  • DBS Recordings to Characterize Movement Facilitation in Parkinson's Disease

    open to eligible people ages 18 years and up

    Several strategies or contexts help patients with Parkinson's disease to move more quickly or normally, however the brain mechanisms underlying these phenomena are poorly understood. The proposed studies use intraoperative recordings during DBS surgery for Parkinson's disease to understand the brain mechanisms supporting improved movements elicited by external cues. The central hypothesis is that distinct networks are involved in movement improvement depending on characteristics of the facilitating stimulus. Participants will perform movement tasks during awake surgery performed exclusively for clinical indications. The identified biomarkers may provide targets for future neuromodulation therapies to improve symptoms that are refractory to current treatments, such as freezing of gait.

  • Dual Frequency Stimulation in Parkinson's Disease

    open to eligible people ages 18 years and up

    Deep brain stimulation (DBS) in the dorsal region of the subthalamic nucleus (STN) is very effective for reducing motor symptoms of Parkinson's disease (PD). Modeling studies suggest that this therapy may result in current spread into the ventral STN, causing altered cognitive processes. As a result, current stimulation parameters often lead to worsening in verbal fluency, executive function, and, particularly, cognitive control. There is evidence suggesting that low frequency oscillatory activity occurs across brain circuits important in integrating information for cognition. Preclinical studies and human recording studies indicate these low frequency theta oscillations drive cognitive control during cognitive tasks. Thus, the purpose of this study is to determine the safety, tolerability, and efficacy of low frequency stimulation (LFS) of the ventral STN alongside standard high frequency stimulation (HFS) of the dorsal STN in patients with PD.

  • LIFUP for Treatment of Motor Deficits in Parkinson's Disease

    open to eligible people ages 18-85

    The study will test the feasibility of using Low Intensity Focused Ultrasound Pulsation (LIFUP) to treat motor symptoms in Parkinson's Disease (PD). LIFUP is a new technique that can increase brain activity in highly specific target areas and is MRI compatible. Thus, in real-time, it is possible to directly observe how LIFUP changes the brain areas important in PD by measuring its effects on brain activity, blood flow, and brain connectivity. If successful, this research will mark the first step towards a novel, non-invasive, non-medication treatment for PD.

  • Non-invasive Brain Mapping of Movement Facilitation in Parkinson's Disease

    open to eligible people ages 18 years and up

    Several strategies or contexts help patients with Parkinson's disease to move more quickly or normally, however the brain mechanisms underlying these phenomena are poorly understood. The proposed studies use complimentary brain mapping techniques to understand the brain mechanisms supporting improved movements elicited by external cues. The central hypothesis is that distinct networks are involved in movement improvement depending on characteristics of the facilitating stimulus. Participants will perform movement tasks during recording of brain activity with EEG and MRI. The identified biomarkers may provide targets for future neuromodulation therapies to improve symptoms that are refractory to current treatments, such as freezing of gait.

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

    Sorry, in progress, not accepting new patients

    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.

  • Blood Pressure on Cognition and Cerebral Hemodynamics in PD

    Sorry, not yet accepting patients

    The goal of clinical trial is to learn about how blood pressure fluctuations affect cognitive performance (thinking abilities) and brain blood flow in persons with Parkinson's disease with and without orthostatic hypotension (low blood pressure when standing). The main questions it aims to answer are: - Is there a certain level of blood pressure that correlates with change in cognitive performance while upright? - Is there a certain level of change in brain blood flow that correlates with change in cognitive performance when upright? - How does cognitive performance differ between persons with Parkinson's disease that have orthostatic hypotension and those without orthostatic hypotension? - How does cognitive performance differ between the supine (laying down) and upright positions? - How do blood pressure and brain blood predict changes in cognitive performance over two years? Participants in this study will undergo the following procedures: - Complete a screening visit with questionnaires, medical history, physical exam, and head-up tilt-table test. - Attend one baseline study visit, during which they will undergo a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. Simultaneously, during the experiments we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS), a non-invasive device that uses light sensors to detect changes in brain blood flow. - Attend one two-year follow-up visit, during which they will repeat a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. During this visit, like before, we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS). Researchers will compare participants with Parkinson's disease with and without orthostatic hypotension in the laying down and upright positions to see if there are changes in thinking abilities between these groups.

  • Osteopathic Manipulative Treatment (OMT) on Gait Biomechanics in Parkinson's Disease

    Sorry, in progress, not accepting new patients

    Parkinson's disease (PD) is a neurological disorder that puts individuals at high risk for injuries and long-term disabilities as a result of a fall or other trauma. Injuries sustained from falls account for many deaths as well as thousands of hospital admissions and nursing home stays every month. Quality of life and even longevity itself is reduced due to the resulting surgeries, immobility, complications and even cognitive impairments that can follow. The proposed study will explore beneficial impact of a treatment modality (OMM/OMT) that may significantly reduce the morbidity of this condition by comparing 6 weeks of OMT versus 6 weeks light touch intervention versus 6 weeks care as usual to improve gait in individuals with PD. Gait will be measured at mid-treatment, post-treatment and 4-week follow-up.

  • Ketamine for Veterans With Parkinson's Disease

    Sorry, not yet accepting patients

    Parkinson's disease (PD) is a devastating illness that has a growing impact on Veterans. One of the most disabling symptoms is depression, which is common in PD and linked to poor quality of life and higher risk of suicide. Unfortunately, there is a lack of effective treatments for depression in PD. Ketamine, which has rapid and potent antidepressant effects, is a potential option but has not been tested in Veterans with PD. Studies in rodents show that ketamine may not only improve depression in PD, it may target two of the underlying drivers of the disease: (1) reduced neuroplasticity, or the brain's ability to adapt and remodel itself; and (2) elevated inflammation. The investigators are conducting a randomized, placebo-controlled study to examine if a dose of intravenous (IV) ketamine improves depression in Veterans with PD. The investigators will also examine ketamine's effects on neuroplasticity and inflammation, which will help us understand how ketamine works in PD and if it can be a useful treatment for Veterans with the disease. This study will lay groundwork for a larger clinical trial across multiple VA sites.

  • Microbiota Intervention to Change the Response of Parkinson's Disease

    Sorry, currently not accepting new patients, but might later

    The clinical phenotype of Parkinson's disease (PD) is quite variable, as is the response to and side effects from medications. While many patients respond to carbidopa/levodopa early on, motor fluctuations and dyskinesias can become a problem as the condition progresses, causing significant impairment in function and quality of life. The gut microbiome is of increasing interest in PD, potentially contributing to pathophysiology and clinical phenotype. Furthermore, gut bacteria are capable of metabolizing levodopa, which may decrease its ability to reach the central nervous system and could explain the variable effect seen clinically. Altering the population of drug-metabolizing bacteria could improve the clinical symptoms of PD and the benefit seen with medications. The investigators hypothesize that the gut microbiome in people with PD correlates with their phenotypic characteristics, which can be improved with targeting the microbiome through dietary or therapeutic interventions. The investigators propose a two-part clinical trial. First, a cross-sectional analysis will correlate the microbiome profile with (a) the clinical phenotype of PD and (b) medication response. Second, a randomized, controlled trial, will evaluate the effect of microbiome manipulation on clinical phenotype and medication response. The investigators plan to reduce the level of bacteria through antibiotic use, resetting the potentially disadvantageous microbiome population. Outcomes will include changes in clinical symptoms, alterations in the the microbiome, and changes in serum markers of inflammation. This thorough characterization will broaden our understanding of the gut-brain axis significantly in PD in clinically relevant ways that have yet to be explored.

  • Pimavanserin vs. Quetiapine for Treatment of Parkinson's Psychosis

    Sorry, not currently recruiting here

    Patients with Parkinson's disease (PD) sometimes experience symptoms affecting their movement, such as slowness, tremor, stiffness, and balance or walking problems. Many patients also have other symptoms not related to movement, called non-motor symptoms, which may affect one's mood or emotions, memory or thinking, or cause one to see or hear things that aren't real (hallucinations) or believe things that aren't true (delusions). Hallucinations or delusions, together called psychosis, occur in up to 60% of PD patients at some point in time. Parkinson's disease psychosis can sometimes be associated with decreased quality of life, increased nursing home placement, increased rate of death, and greater caregiver burden. There are approximately 50,000 Veterans with Parkinson's disease receiving care in the VA, and up to 30,000 (60%) of them will experience psychosis at some point in time. Quetiapine is an antipsychotic drug approved by the Food and Drug Administration (FDA) that is the most commonly used medication to treat PD psychosis, but more studies are needed to determine if it works for this condition and is also well tolerated and safe. Pimavanserin is a newer antipsychotic drug approved by the Food and Drug Administration (FDA) specifically to treat PD psychosis, but more studies are needed to determine if it works and its safety. The purpose of this research is to gather additional information on the safety and effectiveness of both Quetiapine and Pimavanserin. By doing this study, the investigators hope to learn which of these medications is the most effective course of treatment for people with PD psychosis.

  • Adverse Events and Change in Disease Activity Of 24-hour Continuous Subcutaneous Infusion Of ABBV-951 In Adult Participants With Advanced Parkinson's Disease

    Sorry, in progress, not accepting new patients

    Parkinson's disease (PD) is a neurological condition, which affects the brain. PD gets worse over time, but how quickly it progresses varies a lot from person to person. Some symptoms of PD are tremors, stiffness, and slowness of movement. This study will assess how safe and effective ABBV-951 is in adult participants with PD. Adverse events and change in disease activity is evaluated. ABBV-951 is an investigational (unapproved) drug containing Levodopa Phosphate/Carbidopa Phosphate (LDP/CDP) given as an infusion under the skin for the treatment of Parkinson's Disease. Adult participants with advanced PD and who have completed M15-736 or M20-339 study will be enrolled. Approximately 130 participants will be enrolled in the study in approximately 60 sites in the United States and Australia. Participants will receive continuous subcutaneous infusion (CSCI) (under the skin) of ABBV-951 for 96 weeks during the Primary Treatment Period and during the optional Extended Treatment Period. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical and remote telephone assessments, blood tests, checking for side effects, and completing questionnaires.
