You use as a control your existing treatment. How can we tell if the new one is better? Use exactly the same tests. Please note I am not talking about finding out if something works. We know it works. (We do need studies of healthy people, to see what is normal and what is not.) How much better, not better than placebo, but better than the best thing we have today, is it?
