yes, I know what it is preclinical. I remember in psychology courses. But I think it mentions that you have passed the preclinical stage when human candidates mentioned. That is the question. Animals have yielded results, replicated in other laboratories (for scientific discourse is replication). The scientific method which, incidentally, positivism, or science was much discussed since the seventies (constructivism, postmodernism) by the impossibility of separating the researcher's object of the subject, but I want to discuss what is science or not. The question suggests you're looking for humans is that candidates and would back the preclinical stage. But it's a big if, I hope more info ... and I guess the days as it moves further information would emerge ...
