Parkinson's Disease Clinical Trials in Portland, OR

The primary purpose of this study is to demonstrate the superiority of UCB0022 as an adjunctive treatment to stable dose of standard-of-care (SoC) (including at least levodopa therapy) over placebo with regard to motor fluctuations time spent in the OFF state (OFF time) in study participants with advanced Parkinson's Disease (PD).

The goal of this intervention is to explore the effectiveness of a Turning Intervention (TURN-IT) to improve quality of turning in participants with Parkinson's Disease (PD). An unique exercise program has been developed - TURN-IT - in which participants practice exercises that focus on physiological constraints that impair turning ability, such as axial rigidity, narrow base of support, bradykinesia, and inflexible set-shifting. The 60 participants with PD and a history of falls in the previous 12 months, will be randomized into a 6-week, 3x/week, one-on-one TURN-IT group or No-Intervention Control group. This pilot intervention study will determine the number of subjects needed for a future clinical trial and will determine the sensitivity to change with rehabilitation our daily-life turning quality measures (such as, mean and variability of number of steps to turn, turn amplitude, turn velocity). The investigators predict that the TURN-IT program will improve turning in daily life enough to justify a larger clinical trial. Read Less

This is a multicenter, 12-week, placebo-controlled clinical trial of CVN424 150 milligrams (mg) tablets in early, untreated Parkinson's Disease (PD). Participants will be randomized in a 1:1 ratio to CVN424 150 mg or placebo at the Baseline Visit. The purpose of this study is to measure effect on motor features with CVN424 tablets compared to placebo in early, untreated PD and to evaluate the potential of CVN424 to improve motor and non-motor functions in participants with early PD who are not taking dopaminergic or anti-PD therapies.

ORION Trial is a trial to evaluate the efficacy and safety of AMX0035 in participants with Progressive Supranuclear Palsy (PSP), consisting of a randomized double blind placebo controlled phase, followed by an optional open-label extension phase. Read Less

This study is a Phase 3 multi-site, randomized, evaluator-masked, study of endurance treadmill exercise on changes in the Movement Disorder Society-Unified Parkinson Disease Rating Scale (MDS-UPDRS) Part III score at 12 months among persons with early stage Parkinson disease. 370 participants will be randomly assigned to 2 groups: 1)60-65% HRmax or 2)80-85% HRmax 4 times per week. The primary objective is to test whether the progression of the signs of Parkinson's disease is attenuated at 12 months in among persons who have not initiated medication for Parkinson Disease (PD) when they perform high-intensity endurance treadmill exercise.

The purpose of this randomized, double-blind, placebo-controlled study is to assess the efficacy of BIA 28-6156 over placebo in delaying clinical meaningful motor progression over 78 weeks in subjects with Parkinson's disease who have a pathogenic variant in the glucocerebrosidase 1 (GBA1) gene (GBA-PD).

The Parkinson's Genetic Research Study (PaGeR), headed by Dr. Cyrus Zabetian, is searching for genes that increase the risk of developing Parkinson's disease (PD) and related disorders. The study is a joint effort by neurologists and researchers across the United States and is sponsored by the National Institutes of Health. The coordinating center for PaGeR is located at the University of Washington and the VA Puget Sound Health Care System in Seattle. Read Less

The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on motor function in people with Parkinson's disease (PD). vCR will be administered with a device called the Vibrotactile (VT) Touch device. vCR can be used in conjunction with medication and is expected to delay the need to increase dopamine medication. It also provides a more flexible alternative to deep brain stimulation (DBS) in that the vCR therapy can be easily stopped or modified to better suit the patients' needs. Read Less

This study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies. Read Less

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. Read Less

The Parkinson Progression Marker Initiative (PPMI) is a longitudinal, observational, multi-center natural history study to assess progression of clinical features, digital outcomes, and imaging, biologic and genetic markers of Parkinson's disease (PD) progression in study participants with manifest PD, prodromal PD, and healthy controls. The overall goal of PPMI is to identify markers of disease progression for use in clinical trials of therapies to reduce progression of PD disability. Read Less
