When and how to include vulnerable subjects in clinical trials
1Department of Bioethics, National Institutes of Health, Bethesda, MD, USA.
Guidance is needed on including vulnerable populations in US clinical trials. A new six-step procedure helps institutional review boards include pregnant women, prisoners, and children while meeting regulations and protecting participant interests.
Area of Science:
- Clinical Trials and Regulatory Science
- Bioethics
- Public Health Research
Background:
- Limited literature exists on when and how to include vulnerable subjects in clinical trials.
- US regulations impose strict requirements for including pregnant women/fetuses, prisoners, and children.
- Excluding these groups from trials can reduce their value, particularly for pragmatic trials, and harm vulnerable populations.
Purpose of the Study:
- To provide guidance on including vulnerable subjects in US-regulated clinical trials.
- To develop a decision procedure for institutional review boards (IRBs).
- To balance regulatory compliance with the ethical inclusion of vulnerable populations.
Main Methods:
- A six-step decision procedure is proposed for IRBs.
- The procedure addresses when and how to include vulnerable subjects.
- Focus on compliance with US regulations and minimizing negative impacts.
Main Results:
- The manuscript outlines a structured approach for IRB decision-making.
- The procedure aims to facilitate the inclusion of vulnerable groups in clinical research.
- It offers a framework for satisfying regulatory requirements ethically.
Conclusions:
- A systematic procedure can help IRBs navigate the inclusion of vulnerable subjects in clinical trials.
- This approach supports the ethical conduct of research involving pregnant women, prisoners, and children.
- Minimizing exclusion enhances trial value and protects vulnerable populations' interests.
