In a setting with a standard of care for a serious illness, is it ethical to conduct a trial designed to demonstrate superiority over placebo?

• A. True
• B. False
• C. Not applicable
• D. Not sure

Answer: (A)

In trials for serious illness, you can ethically test a new treatment against placebo when both groups continue to receive the established standard of care. Withholding proven therapy would be unethical, but adding the experimental treatment on top of what’s already proven to help, and comparing it to standard care plus placebo, allows researchers to determine if the new option provides additional benefit. This setup respects patient safety, maintains access to proven treatments, and rests on equipoise—the genuine uncertainty about which approach is better. If those conditions are met, a trial designed to demonstrate superiority over placebo is ethically acceptable.
