Clinical trials are not true repeatable, scientific experiments. They're really just controlled studies which are the best that can be done in the absence of the possibility of a controlled experiment. In psychology, this however is just the tip of an iceberg of problems with such research being unscientific.

You don't actually have to re-run it with the exact same specimens or subjects; they can be sampled from some larger population that you're studying (e.g., patients with depression). Nevertheless, you can often do something like a cross-over design that lets you repeatedly test the same patients in different conditions.
