Clinical Trials Legislation - Preparing for the Revision of the European Directive Scheduled for 2011

The recommended changes could be made within the scope of a European Regulation, avoiding the need to transpose it at a later date into each country's regulations, which is a source of possible lack of harmonisation. More specifically, for trials with institutional sponsors and/or investigator driven trials such as “drug therapy strategy trials”, modulating restrictions according to the “risk added by the research” would enable the trial's organisation to be simplified regarding monitoring, adverse reactions reporting and study drugs labelling.
