There was a piece on Radio 4's 'Thinking Allowed' yesterday in an interview with Professor Adam Hedgecoe about 'normalisation' of practice. He describes how it had become normal to dose subjects in clinical trials of new medicines at fairly short intervals. After the extremely serious adverse events experienced by the volunteers that participated in the trial there was a lot of hoopla by 'experts' stating that short dosing intervals were wrong and inappropriate. The fact is, that everybody did it this way. It goes without saying that the more cautious approach that we take today is better.
It was good to hear an interview that didn't seek to sensationalise the story.
