Clinical trials are undertaken to develop better medicines, an improved understanding of medicines' studies and to improve the safety of medicines.
All trial protocols are assessed by the Local Research Ethics Committee (LREC) to ensure that the trial will be safe and will add to the sum of knowledge about medicines.
Only when the LREC is satisfied can patients be recruited for the trial. Each trial is run according to a strict protocol and procedures are in place to ensure that all records are kept up to date. Only Senior Doctors are permitted to introduce a patient to a trial.
