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 g...

50 participants with Parkinson's disease will be recruited to complete actigraphy studies to assess sleep disturbances. For this, participants will wear an Actigraph for seven days. Thirty of these participants with sleep disturbance will go on to receive a tailored lig...

In this study, researchers will learn more about a study drug called BIIB122 in participants with early-stage Parkinson's disease (PD). The study will focus on participants with a specific genetic variant in their LRRK2 gene. The main question researchers are tr...

This study aims to evaluate the impact of the frequency of assessments on the variability over time, reliability, and compliance for the Parkinson's disease (PD) diary in patients with PD in whom medications do not provide adequate control of symptoms.

In this study, researchers will learn more about a study drug called BIIB122 in participants with early-stage Parkinson's disease (PD). In this study: - Participants will take 225 milligrams (mg) of BIIB122 or a placebo as tablets by mouth. A placebo looks like ...

This open-label study is designed to assess the long-term safety and tolerability of dipraglurant in PD patients for up to 52 weeks (at doses of 150-300 mg per day) for patients that have completed an Addex sponsored double-blind clinical trial of dipraglurant.

This study is designed to evaluate the safety and efficacy of dipraglurant in PD patients with dyskinesia (randomized 1:1 to receive active or placebo) for 12 weeks (1 week at 150 mg per day and 11 weeks at 300 mg per day). The primary efficacy assessment will be ba...

This is a double-blinded, controlled, randomized clinical trial (RCT) to establish the safety and efficacy of a non-invasive neuromodulation device for treating symptoms associated with Parkinson's disease.

Single site observational study focused on elucidating the genes and biochemical pathways involved in causing Parkinson disease.

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 ...

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...

This is a multi-center, randomized, double blind, active controlled clinical Study. Following a screening period, eligible subjects will be enrolled to an open-label oral IR LD/CD adjustment period; then an open-label ND0612 conversion period; then after optimizatio...

This study will assess the safety and tolerability of daily oral administration of nilotinib (150-300mg once daily) in Parkinson's Disease.
