The use of placebo controls in experiments is not required to make a valid experiment. If you tell the research subjects that there are, say, 4 treatment regimens which the doctors have roughly equal expectation to work, and they're randomly assigned to them, then there's a lot less interference of the sort described above, and the doctors can tell the truth, and the experiment still yields useful information.
