Using an active comparator asks: does the new treatment offer more benefit (or a better safety profile) than the standard therapy patients would normally receive? This approach is chosen when an effective treatment already exists. It protects participants from being deprived of proven care by ensuring they aren’t randomized to a placebo when a beneficial therapy is available. It also yields clinically meaningful information for clinicians and patients about how the new option stacks up against current practice. Placebo controls aren’t inherently unethical, but they are appropriate only when no proven effective therapy exists or when withholding treatment does not put participants at risk.
