Abstract

This chapter considers the ways in which early trials of new drugs differ from trials of established treatments. Greenwood and Todd [243] have defined three phases of early trials: trials to determine safety and early clinical pharmacology (phase I); trials to determine clinical efficacy and further clinical pharmacology (phase II); and trials for the early clinical development of the drug (phase III). A regulatory authority may be involved in these early trials and provide the approval necessary for the general release or marketing of a drug.
