The ethics of clinical trials.
In summary, the discussion by Professors Helmchen and Müller-Oerlinghausen of the morality of clinical trials has emphasized a point that is frequently overlooked. It is an essential to consider those situations in which it might be unethical not to conduct a trial as it is to be concerned about the ways in which trials might restrict the rights of the individuals taking part in them. They and I have dealt mainly with the first of these two issues because it has been relatively neglected. The second is, of course, equally important and has rightly received much attention. Both matters deserve further public discussion.
