The state of Washington currently has 22 active clinical trials seeking participants for Parkinson's Disease research studies. These trials are conducted in various cities, including Seattle, Spokane, Tacoma and Bellevue.
A Phase 2 Study of NEU-411 in Companion Diagnostic-Positive Participants With Early Parkinson's Disease
Recruiting
The goal of this Phase 2 clinical trial is to investigate the efficacy and safety of NEU-411 in men and women aged 50-80 years with early Parkinson's Disease (PD) who have predicted elevations in the activity of the "leucine-rich repeat kinase 2" ("LRRK2" for short) pathway based on their genetic profile. A DNA test will be used to identify the "LRRK2-driven" population with predicted elevation in the LRRK2 pathway. Participants will: • Take NEU-411 or placebo every day for 52 weeks

A Phase 1b Study of the NLRP3 Inhibitor VENT-02 in Patients With Mild to Moderate Parkinson's Disease
Recruiting
This trial is a randomized, double-blind, placebo-controlled Phase 1b study evaluating the safety/tolerability, PK, and pharmacodynamics of VENT 02, administered orally at 1 dose level twice daily (BID) over 28 days in patients with mild to moderate Parkinson's disease. The study includes a screening period, a 28-day double-blind treatment period, and a 7-day follow-up period after last dose. Approximately 30 patients will be randomized into 1 of the 2 treatment arms.

Safety and Pharmacodynamic Effects of BIIB122 in Participants With LRRK2-Associated Parkinson's Disease (LRRK2-PD)
Recruiting
This Phase 2a, multicenter, randomized, 12-week double-blind, placebo-controlled, parallel-group study, followed by an OLE, is designed to evaluate the safety, tolerability, and pharmacodynamic effects of BIIB122 in participants with LRRK2-PD. LRRK2-PD is defined as Parkinson's Disease (PD) in individuals who are heterozygous or homozygous carriers of a pathogenic LRRK2 variant that increases LRRK2 kinase activity.

Registry of Deep Brain Stimulation With the VERCISE™ System: Vercise DBS Registry
Recruiting
The purpose of this registry is to compile characteristics of world-wide outcomes for the use of Boston Scientific's commercially available Vercise DBS System in the treatment of Parkinson's disease. The utilization of Image Guided Programming (IGP), and other commercially available programming features, used as planning tools for the programming of patients with Boston Scientific's Vercise DBS System are also evaluated. Additionally, the utilization of the DBS Illumina 3D feature that may be... Read More

Effects of an Independent Walking Program With Walking Poles in People With Parkinson Disease
Recruiting
* Study Purpose: The purpose of the study is to compare changes in activity levels and walking in people with Parkinson disease after an 8-week independent walking program with or without using walking poles. * Major parts of the Study: Before the walking program: You will wear an activity sensor on your upper leg for one week to track activity levels. Measurements will be taken of you while you are walking. If you are placed in the walking pole group, you will be trained on how to use walking... Read More

PPMI Clinical - Establishing a Deeply Phenotyped PD Cohort
Recruiting
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.

Real-World Study of ABBV-951 Subcutaneous Infusion to Assess Change in Disease Activity in Adult Participants With Parkinson's Disease
Recruiting
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... Read More

This is a randomized, double-blind, placebo-controlled, multicenter study in participants with Parkinson's disease (PD) with motor fluctuations. Participants will be randomized to receive once-daily oral doses of either 75 milligrams (mg) CVN424, 150 mg CVN424, or a matching placebo for 12 weeks. Participants who successfully complete this study and retain eligibility/suitability will be invited to participate in a future open-label extension (OLE) study.
