Ethically designing research to inform multidimensional, rapidly evolving policy decisions: Lessons learned from the...

Area of Science:

• Medical Ethics
• Clinical Trials
• Public Health Policy

Background:

• Rapidly evolving policy contexts present ethical dilemmas for research sponsors and investigators.
• Challenges include diverging standards of care, pressure to use unproven interventions, and diminished relevance of ongoing studies due to new findings or policies.

Purpose of the Study:

• To review ethical challenges in research conducted within rapidly changing policy environments.
• To analyze the ethical permissibility of continuing the multinational "PROMISE" (Promoting Maternal Infant Survival Everywhere) trial despite evolving guidelines.

Main Methods:

• Case study analysis of the PROMISE trial, a randomized, controlled perinatal HIV prevention study.
• Engagement of an independent international ethics panel to assess the study's standard of care and relevance.
• Review of ethical considerations regarding social value and stakeholder perspectives in policy-driven research.

Main Results:

• The ethics panel deemed continuation of the PROMISE trial ethically permissible.
• Justification included effective interventions across all arms and insufficient evidence of superiority between interventions.
• The panel recognized the ongoing utility of PROMISE data for diverse stakeholders.

Conclusions:

• Trials addressing evolving policy issues require mechanisms to reassess social value.
• Research value can differ among stakeholders with legitimate, varied interpretations of evidence.
• Four reasons for ethically justifiable deviations from standard of care post-policy change are presented, with suggestions for improved trial oversight.
