There is a terribly sad story in the UK about clinical trials that have gone (badly) wrong leaving six people critically ill in hospital.

Radio 5 carried an interview with a person who has taken part in previous trials. He was so full of praise for Parexel that I thought he was a stooge.

That was, until, he uttered the unfortunate words

‘So, 1,000 GBP for one trial and 750 GBP for the second. For a student, that is a lot of money and can actually be life-changing’
