The average cost of clinical trials has risen to nearly 60% of total development costs. Patient recruitment delays and a low retention rate are key factors in this increase of costs, leading to a delay in product launch and a subsequent reduction in product exclusivity. Patient recruitment, if not adequately planned and managed, can extend the development timeline by a number of years. Retention of patients throughout the life of a clinical trial is essential to obtaining the best data sets for analysis and subsequent filings. In order to optimize both recruitment and retention there needs to be a plan and performance management approach based on evidence, data and a set of tools you know will work. This conference is intended to cover the latest differentiators in recruitment and retention; the newest opportunities in online social networks, EMRs and Big Data to support decision making; evidence-based identification and selection of investigators; recruitment of special populations; and lessons learned from various therapeutic areas. "Evidence-Based, Data-Driven Patient Recruitment and Retention" will provide a comprehensive real-world perspective on this challenging arena, with key takeaways you can implement right away to ensure the best results.
