Recruitment and enrollment in clinical trials remain key sources of cost and frustration for sponsors. Recent data shows that nearly 80% of trials fail to meet enrollment timelines and that approximately one third of all Phase III study terminations are a result of poor enrollment. These persistent challenges can lead study leaders to feel helpless. Traditionally, study teams have had little to no control over study recruitment and, as time has passed, the belief that recruitment must be difficult and chaotic has grown roots. Many feel that lengthy recruitment periods and over-recruiting are unavoidable constants and
that, in terms of enrollment diversity, you simply get what you get.
