To Evaluate the Efficacy of CVN424 in Parkinson's Disease Participants With Motor Complications
Recruiting
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 or 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.

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.

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.

Evaluation of Neurocognitive Changes in Parkinson's Disease After Low Frequency Burst Stimulation
Recruiting
This study aims to determine whether direct brain stimulation of specific regions and ranges improves cognition in people with Parkinsons Disease (PD) who already have a deep brain stimulator implanted. Research activities consist of 32 subjects undergoing stimulation changes to their device and being administered neurocognitive tests to evaluate the changes. An fMRI scan will also be done at baseline and at weeks 15 and 27.
All subjects will undergo the stimulation changes in a randomized doub... Read More

Combined STN and NBM Deep Brain Stimulation for Mild Cognitive Impairment in Parkinson's Disease
Recruiting
The goal of this clinical trial is to evaluate the safety and tolerability of a novel deep brain stimulation (DBS) of the Subthalamic Nucleus (STN) and Nucleus Basalis of Meynert (NBM) to treat cognitive and cognitive-motor symptoms in individuals with Parkinson's disease. The main question it aims to answer is:
Is a combined deep brain stimulation approach targeting the STN and NBM with four DBS leads safe and tolerable for cognitive and cognitive-motor symptoms in individuals with Parkinson's... Read More
