Regarding double-blind tests with placebo...

Is it really necessary to incorporate a placebo in the testing? After all, it's been used in past trials (e.g. donepezil) so they should already know what to expect. Seems to me that the transitory property should apply here... If A>B and B>C, then A>C. In other words, if donepezil is better than placebo, then the double-blind test should be, both, vs. and with donepezil and not placebo. Also, not fair to the patients to get only a placebo.
