Post-trial access in implanted neural device research: Device maintenance, abandonment, and cost

Area of Science:

• Neuroscience
• Biomedical Engineering
• Clinical Research Ethics

Background:

• Clinical trial participants using experimental neural devices for severe conditions often lose access to therapy and maintenance after trials conclude.
• Post-trial obligations are well-studied for drugs but underexplored for neural devices.

Purpose of the Study:

• To examine stakeholder perspectives on post-trial access to and maintenance of experimental neural devices.
• To understand researcher and patient-participant views on continuing therapy and device upkeep after clinical trials.

Main Methods:

• Surveyed 44 stakeholders: 23 researchers and 21 patient-participants in implantable neural device trials.
• Gathered data on concerns, barriers, and suggestions for post-trial management.

Main Results:

• Researchers expressed concerns about current post-trial management, citing cost as a barrier and proposing system improvements.
• Most patient-participants were unaware of post-trial access but believed they should retain beneficial devices and supported enhanced support for device maintenance.

Conclusions:

• This study is the first in-depth examination of researcher perspectives and one of few on patient-participant perspectives regarding post-trial access to neural devices.
• Findings can inform ethical and policy decisions concerning post-trial access to implantable neurotechnology.
