Parkinson's Disease Clinical Trials in Orlando, FL

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

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, immunogenicity, biomarkers, and clinical efficacy measures. Patients will continue to be followed for an additional 4 years to continue to monitor safety as well as selected biomarker and efficacy measures. Read Less

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 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

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.

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in patients with a diagnosis of Parkinson's Disease consistent with the UK Parkinson's Disease Society (UKPDS) Brain Bank diagnostic criteria, who are experiencing wearing off symptoms and levodopa-induced dyskinesia.

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 based on the Unified Dyskinesia Rating Scale (UDysRS). Patients who complete the 12-week blinded treatment period may have the option to roll into an open-label safety extension study for an additional 12-month treatment period. Read Less
