A Non Investigational Medicinal Product (NIMP) is a medicinal product which is not classed as an IMP in a trial, but may be taken by subjects during the trial. Examples include concomitant or rescue/escape medication used for preventive, diagnostic or therapeutic reasons and/or medication given to ensure that adequate medical care is provided for the subject during a trial.
