A new ethical framework to determine acceptable risks in fetal therapy trials

Area of Science:

• Medical Ethics
• Fetal Medicine
• Clinical Research

Background:

• Fetal therapy trials present complex ethical dilemmas, balancing risks and benefits for both fetuses and pregnant individuals.
• Current regulatory guidance is insufficient, and many ethical frameworks are overly restrictive, hindering the advancement of novel fetal therapies.
• There is a need for a refined ethical approach to navigate the complexities of fetal therapy research.

Purpose of the Study:

• To develop a novel ethical framework for evaluating the risk-benefit profiles of fetal therapy trials.
• To address the limitations of existing ethical guidelines and facilitate the responsible development of fetal therapies.
• To ensure robust ethical oversight in clinical research involving pregnant individuals and fetuses.

Main Methods:

• A comprehensive review of existing regulatory and ethical guidance pertaining to fetal therapy trials was conducted.
• Conceptual analysis was employed to design a new ethical framework.
• The framework is grounded in established ethical principles for clinical research.

Main Results:

• A new framework for assessing risks and benefits in fetal therapy trials is proposed.
• The framework posits that potential benefits (to fetus, pregnant person, and society) must exceed risks.
• It also requires that the risk-benefit profiles for the fetus and the pregnant person individually be deemed appropriate.

Conclusions:

• The proposed framework aims to enable crucial research while safeguarding fetuses and pregnant individuals from undue harm.
• This ethical approach seeks to balance scientific advancement with the protection of vulnerable populations.
• It provides a pathway for conducting important fetal therapy studies responsibly.
