Connect the right participants to the right studies at the right time.

According to industry research, most clinical trial research studies fail to reach their enrollment targets. With trial activity increasing but performance dropping, finding the right participants is a major challenge – and one that puts the success of studies at risk for sponsors, CROs, and sites if they cannot master it.

WCG’s end-to-end participant enrollment and retention solutions provide the necessary resources for screening, enrolling, and retaining participants to meet your program goals. Designed to engage the right participants for your studies and your sites, our bespoke services help you identify and refer candidates to clinical sites. Once enrolled, we provide the necessary resources to ensure participants stay engaged, supported and retained for the duration of the study.
