Which measure helps ensure fair post-trial access to benefits for participants in international trials?

• A. Providing post-trial access to benefits for participants and communities
• B. Withholding results from participants
• C. Limiting benefits to new participants
• D. Selling data for profit

Answer: (A)

Post-trial access to benefits is about fairness in research ethics. When participants in international trials, often in resource-limited settings, take on risk and contribute to the knowledge gained, there is a moral obligation to ensure they and their communities can continue to receive benefits if the intervention proves helpful. Providing ongoing access after the study ends helps prevent exploitation, supports health equity, and respects participants’ contributions, aligning with international ethical guidelines.

This approach is the best because it directly implements justice and beneficence in a practical, measurable way—ensuring real, ongoing health benefits rather than leaving participants without access. The other options miss this core obligation: withholding results deprives participants of information and potential care; limiting benefits to new participants perpetuates inequity by denying ongoing benefits to those who helped generate the knowledge; selling data for profit places financial interests above participant welfare and privacy.
