[Critical value of bilirubin in the selection of healthy volunteers in for phase I].

10% of young male healthy volunteers have a total bilirubin value over 20 mumol/l; thus such a value appears not relevant as screening cut off point in clinical pharmacology. This study was intended to confirm if a 27 mumol/l cut off point previously defined by the authors does not support a risk. This study dealt with 487 subjects who had together measurements of total bilirubin value and lab.

Adverse events in phase one studies: a study in 430 healthy volunteers.

All the clinical, laboratory and electrocardiographic adverse events detected during 24 Phase I studies in the same unit over a 5 y period are reported here. 430 healthy male volunteers were involved, corresponding to 5488 days of follow-up. The overall incidence of adverse events was 13.
