In non-therapeutic trials, what are the stated requirements and justification?

• A. Requirements: informed consent and accepted risks and benefits; Justification: potential good to the subjects and future patients
• B. Requirements: no consent; Justification: risk-free
• C. Requirements: secrecy about results; Justification: privacy
• D. Requirements: compensation; Justification: sponsor profit

Answer: (A)

Non-therapeutic trials are about gaining knowledge without offering direct medical benefit to the participants. The basic requirements are that people give informed consent after being told the purpose, procedures, potential risks, and the fact that there may be no personal therapeutic benefit. In addition, the study must have a favorable risk-benefit balance, meaning the risks are minimized and reasonable in light of the valuable knowledge expected to be gained. The justification for this kind of research rests on its social value: generating generalizable knowledge that can improve future care for patients. While participants might receive some ancillary or non-therapeutic benefits (like health monitoring), there is no expectation of personal treatment benefit, which is why consent and a solid risk-benefit assessment are essential.
