There is a reason (many actually) because clincal trials are subject to countless checks and hurdles before they are carried out: you cannot play with people's lives to prove your theories, regardless of how good your intentions are and how much you are convinced these theories are correct.
If the theory is based on flawed data (that is to say, there is no real ground on which to expect positive results), giving false hope is just sadistic.
