Ethical Considerations for Clinical Research in Persons with a Terminal Illness

Area of Science:

• Bioethics
• Clinical Research Ethics
• Palliative Care Research

Background:

• Clinical research involving persons with a terminal illness (PTI) presents unique ethical challenges.
• Existing ethical guidelines offer limited or conflicting advice for protecting these participants.
• Balancing participant protection with the need for valuable research is crucial, especially in palliative care and geriatrics.

Purpose of the Study:

• To propose an ethical framework for clinical research with persons with a terminal illness (PTI).
• To address challenges in meeting ethical requirements due to limited life expectancy and potential decisional impairment in PTI.
• To provide considerations for Institutional Review Boards (IRBs) evaluating such studies.

Main Methods:

• Grounded in general research ethics requirements.
• Proposes a framework based on the defining characteristic of PTI: limited life expectancy.
• Explores challenges in meeting ethical requirements like social value, risk-benefit ratio, participant selection, and informed consent.

Main Results:

• Limited life expectancy and decisional impairment in PTI can complicate adherence to ethical research standards.
• Identifies specific ethical requirements that are particularly challenging to meet in studies involving PTI.
• Suggests strategies to overcome these challenges and ensure ethical research conduct.

Conclusions:

• The proposed framework aims to protect persons with a terminal illness while facilitating their participation in important clinical research.
• Offers guidance for IRBs to balance ethical considerations and research opportunities for PTI.
• Emphasizes the need for tailored ethical approaches for research involving vulnerable populations with limited life expectancy.
