Abstract

Mechanistic studies may be defined as ‘an experiment, using an intervention in healthy subjects or patients, to better understand human biology and/or disease’. Such studies provide useful physiological insights into clinical conditions in humans and expand our knowledge of physiology in health and disease. Well-planned mechanistic studies are therefore a vital step in progressing drug discovery in humans. It is important in such studies that the rights and safety of research participants are preserved, while at the same time not allowing lengthy and complex approval procedures to stifle and potentially prohibit this type of research
