This practicum report explores some of the reasons why sponsors in clinical research trials occasionally need to enlist the aid of investigative add-on sites, and highlights some of the unique opportunities that are presented to prospective add-on sites. Advanced Care Research Centers (ACRC) Trial’s current involvement in a contraceptive study, as an investigative add-on site, provides this report with a case study, where observations and the analysis of enrollment data can appraise their success as an add-on site. Past trials are also assessed in order to supplement other themes raised in this discussion.application/pdfenBehavior and Behavior MechanismsHealth Services Researchinvestigative add-on sitesecondary siteenrollment periodInternship Practicum Report
