The main idea is that new interventions should be compared to the best proven existing treatment. This ensures participants receive care that is at least as good as what is already known to work, and it makes the trial results meaningful for real-world practice. Placebo controls aren’t the default when an effective therapy exists; they’re only acceptable if no proven intervention exists or if there are scientifically valid reasons that justify the use of a placebo without exposing participants to unnecessary harm. Using historical controls is prone to bias and unreliable conclusions, and comparing against a standard treatment regardless of its efficacy would fail to protect participants or provide a trustworthy benchmark. So, testing a new intervention against the best current proven intervention is the ethical and practical standard.
