NCT07656129
Parkinson's disease (PD), the most common movement disorder, is characterized by motor symptoms including tremor, rigidity, bradykinesia, and postural instability. These symptoms substantially impair quality of life and increase the risk of falls, disability, and accidental injury, representing a major therapeutic challenge. External trigeminal nerve stimulation (eTNS), a non-invasive neuromodulation technique, has shown promising potential in PD and other movement disorders. A clinical study published in 2017 suggested that trigeminal nerve stimulation may contribute to the alleviation of motor symptoms in patients with PD. In 2023, the U.S. Food and Drug Administration cleared the Portable Neuromodulation Stimulator (PoNS) as an adjunctive treatment for gait impairment caused by multiple sclerosis; the lingual nerve is a branch of the mandibular division of the trigeminal nerve. In the same year, experimental evidence showed that trigeminal nerve stimulation could activate intracranial dopaminergic neurons and modulate dopamine release in mice. These findings suggest substantial potential for eTNS in modulating motor dysfunction in PD, although high-level clinical evidence remains lacking. This randomized, within-subject study will evaluate the immediate effects of eTNS at different stimulation frequencies on motor dysfunction in patients with PD. Gait parameters will be quantitatively assessed using the IDEEA gait system, together with the MDS-Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS Part III), Tinetti Gait Scale, and Hoehn and Yahr Scale. This within-subject study comprises three 20-min stimulation conditions: 120-Hz eTNS, 40-Hz eTNS, and sham stimulation. Each patient with Parkinson's disease will complete all conditions in a single session in randomized order. Instrumented gait analysis, together with motor and gait rating scales, will be used to quantify immediate post-stimulation changes in gait and motor function relative to baseline.
NCT07604116
The non-randomized, open-label phase I study aims to evaluate the safety, tolerability, biodistribution, radiation dosimetry, and pharmacokinetics of SST001 in healthy volunteers, patients with MSA and patients with PD.
NCT07340073
Deep brain stimulation (DBS) is a surgical implant procedure for the treatment of Parkinson's Disease (PD) utilizing medical devices approved by the FDA. A novel approach to current DBS approaches is called "Coordinated Reset" DBS (CR-DBS) which uses different patterns of stimulation at lower currents and can address the limitations of traditional DBS (T-DBS) that uses continuous high amplitude and high frequency stimulation. This study will evaluate the safety and short-term efficacy of CR-DBS in PD. The results from this study will significantly advance the development of CR-DBS for the treatment of PD. Findings in this study will also provide the rationale for further development of this novel DBS approach for other neurological and psychiatric disorders.

Eligible participants will undergo a series of assessments and examinations, including cognitive and memory scale tests, routine blood tests, ApoE genetic testing, cerebrospinal fluid testing, brain MRI, functional MRI, and FDG-PET/AV45-PET scans when necessary. Additional samples such as saliva, nasal secretions, and stool may also be collected. Most evaluations are provided free of charge to support diagnosis and treatment guidance. Participation is voluntary. All personal information and research data will be kept confidential. Potential benefits include access to expert clinical care and free cognitive assessments for disease evaluation. Possible inconveniences include time commitment and temporary discomfort during examinations; medical support will be provided if needed.
NCT07533591
The investigators propose a gene therapy strategy for Parkinson's disease - a chemogenetic inhibition technique to intervene in the abnormal activity of the subthalamic nucleus in Parkinson's patients. The investigators design and construct a therapeutic injection agent called STP-001, through an efficient adeno-associated virus capsid (AAV), a neuronal promoter (hSyn), and a chemogenetic effector element (hM4Di). Then, the drug was accurately injected into the bilateral subthalamic nuclei through stereotactic surgery. After the surgery, combined with clozapine, the abnormal activity of the subthalamic nucleus was precisely intervened to improve the core motor symptoms of Parkinson's disease.
NCT07310264
This is a first-in-human (FIH) study of orally administered VT-5006 (also known as AX-5006) in healthy adult volunteers (HVs) and adult participants with Parkinson's disease (PD). The goal of this clinical trial is to learn if VT-5006 is safe and tolerable in healthy volunteers and in participants with PD. It has three Parts (A, B, and C). Part A: Healthy volunteers aged 18-54 will attend a screening visit, take a single dose of VT-5006 or matching placebo after an overnight fast, stay in the clinic for three nights, and complete a follow-up visit. One group of participants in Part A will be asked to return to the clinic after approximately two weeks, take a single dose of VT-5006 or matching placebo after consuming a high-fat meal and stay in the clinic for another three nights. Part B: Healthy volunteers aged 18-54 will attend a screening visit, take one dose of VT-5006 or matching placebo each day for seven days after fasting overnight, stay in the clinic for 10 nights, and complete a follow up visit. Part C: Participants with PD aged 40-80 will attend a screening visit, take one dose of VT-5006 (high dose), VT-5006 (low dose), or matching placebo each day for 28 days, complete two overnight stays in the clinic, attend three clinic visits, one phone call and a follow up visit.
NCT07485621
The goal of this observational study is to assess whether deep brain stimulation (DBS) contact selection in Parkinson's disease could be informed by subcortical local field potential (LFP) recordings. The main question it aims to answer is: Aligns stimulation contact selection based on subcortical LFP recordings with clinically optimized contact selection? Participants will undergo LFP recordings that are part of standard clinical care during their routine hospital visits.
NCT07322887
The main goal of the study is to investigate how well the new drug SUL-238 works in Parkinson's Disease (PD). This is done by means of an MRS scan. An MRS scan is similar to a regular MRI scan. It will also learn about the safety of new drug SUL-238. The main questions it aims to answer are: * Does new drug SUL-238 improve the mitochondrial function in patients with Parkinson's Disease (PD)? * What medical problems do participants have when taking new drug SUL-238? Researchers will compare new drug SUL-238 to a placebo (a look-alike substance that contains no drug) to see if SUL-238 works to improve mitochondrial function in patients with PD. Participants will: * Take new drug SUL-238 or a placebo every day for 28 days * Visit the clinic once every 2 weeks for checkups and tests during the treatment period and finally 28 days after the last dose of SUL-238 * Keep a diary of their symptoms and the number of times they use oral new drug SUL-238
NCT07457710
Individuals with Parkinson's Disease (PD) often have motor difficulties that can negatively impact daily activities and their quality of life. Research has shown that to slow the progression of these symptoms, patients should partake in effective physical rehabilitation. However, effective physical rehabilitation has many barriers, including timing, cost, and other personal or system-level challenges. The purpose of this study is to evaluate the haptic remote rehabilitation system for patients with PD using a randomized controlled trial (RCT) in a field environment.
NCT07316296
The goal of this clinical trial is to learn if the medication atomoxetine can reduce freezing of gait in people with Parkinson's disease. The main questions it aims to answer is: Does atomoxetine reduce the frequency or severity of freezing of gait? What role does noradrenaline play in freezing of gait? Researchers will compare atomoxetine to a placebo to see if atomoxetine can improve freezing of gait in people with Parkinson's disease. Participants will: Visit the study site for measurements Take atomoxetine or placebo Perform walking assessments and undergo MRI Complete questionnaires about anxiety, stress, and quality of life
NCT07417280
Low intensity focused ultrasound (LIFUS) has the potential to be used as a means of non-invasive neuro-modulation. To this day, the use of LIFUS is under investigation. Studies in healthy subjects have shown that application of LIFUS to the motor region of the brain can mildly decrease neuron excitability in healthy controls. The purpose of the present study is to evaluate the effects of LIFUS on brain tissue excitability in patients with movement disorders in order to elucidate the therapeutic potential of LIFUS.
NCT07310147
Parkinson's disease (PD) has a substantial impact on daily life and significantly affects functioning, mental health and quality of life. Although considered a disease of the elderly, an early diagnosis is also common. Non-pharmacological interventions have been increasingly recommended for PD, including psychotherapy, with emerging evidence suggesting that Acceptance and Commitment Therapy (ACT) may be suitable to support individuals living with PD. This project aims to expand the current evidence for ACT interventions in this population by developing, implementing, and investigating the preliminary efficacy of a novel online-delivered ACT intervention (Empower your mind to embrace your life) for individuals with a diagnosis of young-onset PD. For this purpose, a feasibility study will be conducted to assess the acceptability and preliminary efficacy of the intervention across two groups (control and ACT intervention). This group-based intervention consists of eight weekly sessions and will be delivered in an online format (via videoconferencing). Outcome measurement will be assessed at pre-intervention, post-intervention, and at 3-month follow-up. When comparing changes in outcome variables between the control and intervention groups at post-treatment, improvements are expected only in the intervention group. These improvements are also expected to be maintained over time (at 3-month follow-up). Lastly, changes in psychological (in)flexibility processes are expected to predict changes in outcome variables in the intervention group. This study will provide important insights to research and clinical practice by providing data on the feasibility and preliminary efficacy of this novel ACT-based intervention for the context of young-onset PD.
NCT06107426
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. The purpose of this study is to evaluate how effective ABBV-951 is in treating adult participants with advanced PD in real world setting. ABBV-951 (foslevodopa/foscarbidopa) is an approved drug for the treatment of Parkinson's Disease. The main ROSSINI study will have approximately 450 adult participants with PD (300 participants new to ABBV-951, up to 150 participants transitioning from open-label extension study) will be enrolled across approximately 60 sites. Decision to treat with ABBV-951 (or continue the treatment in Cohort B) will be made by the doctor prior to any decision to approach the participant to participate in this study. There will be a sub-study that will enroll 40 naïve participants who initiated Foslevodopa/Foscarbidopa treatment for the first time (Cohort A of the ROSSINI parent study only) from 6 to 15 centers in the United States, Germany and Spain. All participants will receive subcutaneous infusion of ABBV-951 for approximately 3 years. Participants will attend regular clinic visits during the course of the study. The effect of the treatment will be checked by medical assessments, and completing questionnaires.
NCT07230366
This study aims to verify the safety and preliminary clinical benefits of long-term gait training using AI-powered smart electric vehicles for patients with neurodegenerative diseases such as Parkinson's disease and dementia.
NCT07213999
The purpose of this research is to test a new recorder that can measure brain activity when stimulation is turned on during deep brain stimulation (DBS) surgery. To continue to improve DBS therapy, the investigators need to better understand the changes in the brain of people with Parkinson's disease (PD). They also need to know how this is affected by DBS. Current recorders measure activity immediately after, but not during, stimulation. Standard-of-care DBS already includes the electrical recording of brain activity during movement of arms and legs. These recordings occur during the microelectrode recording part of the surgery and are used by the medical team to determine where to place the DBS electrode.
NCT03374917
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of 4 weeks of continuous infusion with ABBV-951 in adult subjects with Parkinson's Disease (PD).
NCT06118294
In previous clinical studies, PS128 has been reported to ameliorate motor deficits in Parkinson's disease (PD). PS23 has been reported to delay some age-related disorders. On the basis of previous animal and clinical studies which hope that this study can support the theory of the gut-brain axis, and have the opportunity to realize the relationship between peripheral inflammation and neurodegeneration.
NCT03781167
The purpose of this study was to assess the safety and tolerability of ABBV-951 (Foslevodopa/Foscarbidopa) in participants with Parkinson's disease (PD). This was a single-arm study with preplanned analyses conducted by dose subgroup (Low Dose or High Dose) based on the modal total daily dose (most frequent dose) over the treatment period.
NCT02381444
The aim of this study is to assess the effect of LCIG (levodopa-carbidopa intestinal gel) on HRQL (Health-Related Quality of Life) of participants and compare the Health-Related Quality of Life between participants continuing to levodopa-carbidopa intestinal gel treatments versus participants continuing on oral therapy for Parkinson's Disease.
NCT01883973
Most leading academic centers including Baylor College of Medicine (BCM) perform deep brain stimulation surgery in the awake patient using microelectrode recording to guide final electrode placement. Microelectrode recording is a means of analyzing the electrical activity of the brain, and assessing whether we have found the target for the deep brain stimulator electrode. However, no evidence exists that microelectrode recording improves patient outcomes. The use of microelectrode recording does extend the duration of surgery and there is evidence to suggest that microelectrode recording may increase the risk of bleeding in the brain during surgery.
