The Clinical Trials Charter aims to set a standard of practice for those involved in clinical trials for Parkinson’s.

As researchers, you are responsible for designing and delivering ethical studies that are of relevance to patients; you aim to ensure participants’ safety and to protect their rights and dignity.


As researchers you should strive to:

  • Communicate effectively with all participants and wider stakeholders which will involve:
    • Identifying individuals to be responsible for communication.
    • Producing information about the trial which is accessible and easy to understand.
    • Providing ample opportunity to address participants’ concerns or questions about the study.
    • Involving patient advocates and prospective participants in all aspects of study design and conduct as appropriate.
  • Be transparent and clear in what we hope to achieve from the study, its potential, the risks and benefits.
  • Ensure all appropriate approvals and safeguards are in place prior to the start of the study.

During trial

  • Listen carefully to participants’ concerns and address unforeseen issues rapidly as they arise.
  • Employ and continuously re-evaluate the practices used in this trial, to ensure the optimum care of participants.
  • Communicate effectively and keep trial participants informed, motivated and supported.
  • Use data collected during the trial to re-assess the design and validity of the study and its potential value in future research.

Post trial

  • Create a project debrief for all participants using a range of media and collect feedback from patients on their trial experience (good and bad).
  • Disseminate lessons learnt to the wider Parkinson’s community – best practice should evolve.
  • Communicate the results of the trial to the Parkinson’s and wider communities – if possible publish results as open access.
  • Use information collected from above to improve future trials.
