Parkinson's Disease Clinical Trials in Spokane, WA

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. Read Less

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. Read Less

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 used for the programming of patients with Boston Scientific's Vercise DBS Systems is also evaluated. Read Less

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. Read Less

The purpose of this study is to investigate the safety of Lu AF28996, how well it is tolerated and what the body does to the drug in participants with Parkinson's disease. Read Less

In this study, researchers will learn more about BIIB122 in participants with early-stage Parkinson's disease (PD). The study will include adults aged 30 to 80 who were diagnosed with PD within 2 years of starting the study. The main objective of the study is to learn about the effect BIIB122 has on slowing down the worsening of PD symptoms. The main question researchers want to answer is: - How long does it take for PD symptoms to worsen during BIIB122 treatment? Researchers will answer this and other questions by measuring the symptoms of PD over time using a variety of scoring tools. These include the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the modified Schwab and England Activities of Daily Living Scale (mSE-ADL). The MDS-UPDRS is used to measure symptoms of PD. It has 4 parts: Part I, II, III, and IV. Each part measures different aspects of motor and non-motor symptoms. The mSE-ADL measures a participant's ability to perform daily activities or personal chores. Researchers will also learn more about the safety of BIIB122. They will check participants for adverse events. Adverse events are unwanted health problems that may or may not be caused by the study drug. The study will be done as follows: * Participants will be randomly assigned to take either BIIBB122 or placebo. A placebo looks like the study drug but contains no real medicine. * Neither the researchers nor the participants will know if the participants are receiving BIIB122 or placebo. * Participants will take BIIB122 or placebo tablets by mouth once a day. * The treatment period for each participant will last between 48 and 144 weeks. * There will be a safety follow-up period for 2 weeks after the last dose of BIIB122. * In total, participants will have up to 29 study visits. * Participants will stay in the study for at least 1 year, up to about 3 years.
