The state of California currently has 40 active clinical trials seeking participants for Parkinson's Disease research studies. These trials are conducted in various cities, including Los Angeles, San Francisco, San Diego and Sacramento.
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.

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

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...

Ketamine for Veterans With Parkinson's Disease
Recruiting
Parkinson's disease (PD) is a devastating illness that has a growing impact on Veterans. One of the most disabling symptoms is depression, which is common in PD and linked to poor quality of life and higher risk of suicide. Unfortunately, there is a lack of effective treatments for depression in PD. Ketamine, which has rapid and potent antidepressant effects, is a potential option but has not been tested in Veterans with PD. Studies in rodents show that ketamine may not only improve depression i... Read More

Phase 1/2a Clinical Trial of PR001 (LY3884961) in Patients With Parkinson's Disease With at Least One GBA1 Mutation (PROPEL)
Recruiting
Study J3Z-MC-OJAA is a Phase 1/2a, multicenter, open-label, ascending dose, first in-human study that will evaluate the safety of intracisternal LY3884961 administration in patients with moderate to severe Parkinson's disease with at least 1 pathogenic GBA1 mutation. Two dose level cohorts of LY3884961 are planned (Dose Level 1 and Dose Level 2). The duration of the study is 5 years. During the first year, patients will be evaluated for the effect of LY3884961 on safety, tolerability, immunogeni... Read More

Dual Frequency Stimulation in Parkinson's Disease
Recruiting
Deep brain stimulation (DBS) in the dorsal region of the subthalamic nucleus (STN) is very effective for reducing motor symptoms of Parkinson's disease (PD). Modeling studies suggest that this therapy may result in current spread into the ventral STN, causing altered cognitive processes. As a result, current stimulation parameters often lead to worsening in verbal fluency, executive function, and, particularly, cognitive control. There is evidence suggesting that low frequency oscillatory activi... Read More
