parkinson disease Clinical Trials and Research

Also known as: parkinson's, pd, shaking palsy, paralysis agitans, idiopathic parkinsonism, primary parkinsonism · ICD-10: G20

Parkinson's disease is a progressive disorder that affects movement, often causing tremors, stiffness, and balance problems. Clinical trial research aims to develop new treatments for symptoms, slow disease progression, and understand its causes. Find a Trial helps patients search for active studies.

Common questions about parkinson disease clinical trials

Who can participate in Parkinson's disease clinical trials?

Eligibility criteria vary by study, often including age, disease stage, and overall health. Researchers use these criteria to ensure patient safety and gather relevant data. Information on specific requirements is available on ClinicalTrials.gov.

What are the different phases of clinical trials for Parkinson's disease?

Clinical trials progress through phases (1, 2, 3, 4) to test safety, dosage, and effectiveness. Early phases involve fewer participants, while later phases enroll more people to confirm benefits and monitor side effects. This structured approach helps ensure new treatments are thoroughly evaluated.

Do clinical trials for Parkinson's disease cost money to join?

Typically, participants do not pay to join clinical trials, and study-related medical care is often covered. However, other costs like travel or lost wages are usually not reimbursed. Patients should discuss potential costs with the research team.

What are current research directions in Parkinson's disease clinical trials?

Current research focuses on neuroprotective therapies to slow or stop disease progression, gene therapies, and treatments for non-motor symptoms like sleep disturbances and cognitive changes. Studies also explore new ways to deliver existing medications. Data from ClinicalTrials.gov and NIH RePORTER highlight these areas.

What types of interventions are being studied in Parkinson's disease trials?

Interventions include new medications targeting specific brain pathways, deep brain stimulation (DBS) device improvements, and non-pharmacological approaches like exercise and rehabilitation. Researchers are also investigating cell-based therapies. These studies aim to improve motor and non-motor symptoms.

Are there specific biomarkers being studied in Parkinson's disease research?

Yes, researchers are actively seeking biomarkers to aid early diagnosis, track disease progression, and measure treatment effectiveness. Examples include alpha-synuclein levels in cerebrospinal fluid, genetic markers, and advanced imaging techniques. This research is vital for developing targeted therapies, according to NIH RePORTER.

What might prevent someone from joining a Parkinson's disease trial?

Common exclusion criteria can include other neurological conditions, severe medical comorbidities, certain medications, or a history of specific surgeries. These criteria help ensure participant safety and the integrity of study results. Each trial has unique requirements listed on ClinicalTrials.gov.

What are the potential benefits of participating in a Parkinson's disease clinical trial?

Participants may gain access to new treatments before they are widely available and receive close medical monitoring. They also contribute to scientific understanding, potentially helping others with Parkinson's disease in the future. However, there is no guarantee of personal benefit.

How to find a parkinson disease trial that fits you

  1. Describe your parkinson disease situation in detail — stage if applicable, prior treatments, age, and other relevant conditions.
  2. Use the location filter (worldwide, US, US & Canada, Europe) to narrow to trials near you.
  3. Review each trial's eligibility criteria carefully. Save 2–5 candidates with their NCT numbers.
  4. Discuss with your treating clinician before contacting the research site.
