Path to Parkinson Disease Prevention: Conclusion and Outlook

Area of Science:

• Neuroscience
• Clinical Trial Design
• Parkinson's Disease Research

Background:

• Significant advancements in understanding Parkinson's disease (PD) pathophysiology and prodromal symptoms.
• This progress enables early therapeutic interventions to potentially halt or slow motor PD progression.
• A conference convened to address critical aspects of designing the first PD prevention studies.

Purpose of the Study:

• To summarize opportunities and challenges in designing PD prevention trials.
• To address pivotal questions regarding trial design: participant selection, interventions, outcome measures, and timing.
• To guide responsible and effective planning for future PD prevention studies.

Main Methods:

• Review of critical trial design questions for Parkinson's disease prevention.
• Discussion organized around 'Who (should be enrolled)?', 'What (to test)?', 'How (to measure prevention)?', and 'When (should we start these trials)?'.
• Synthesis of implications for planning and executing prevention trials.

Main Results:

• Identified key considerations for launching the first Parkinson's disease prevention trials.
• Outlined the major opportunities and challenges inherent in designing such trials.
• Highlighted remaining questions requiring careful consideration before trial implementation.

Conclusions:

• Early intervention in prodromal Parkinson's disease is a promising strategy.
• Careful planning addressing participant selection, interventions, outcome measures, and timing is crucial for successful prevention trials.
• Further deliberation is needed to ensure responsible and sustainable development of PD prevention studies.
