Connection ≠ continuity: Rethinking long-term evidence in the age of tokenization

Long-term evidence generation is one of the most pressing challenges in clinical development and one of the least examined. Sponsors invest heavily in trial infrastructure, including tokenization and data linkage, and reasonably assume they have preserved their options for future evidence needs. But the questions that matter most to regulators and payers often emerge after a trial closes, when the trial cohort’s ability to answer them has quietly degraded. This webinar takes an honest look at where current approaches work, where they fall short, and what the implications are for how trials should be designed.

Panelists will examine what tokenization was built to do and where it genuinely delivers value. We’ll look at the specific ways trial cohorts erode over time and why standard tools for evaluating linkage quality often obscure that degradation until it is too late to address. We’ll also discuss what regulators increasingly expect in terms of long-term, high-integrity evidence, and the gap between those expectations and what most current evidence infrastructure can reliably provide.

The conversation will be grounded in real experience: from sponsors who have navigated these challenges firsthand, from a regulatory perspective on what sufficient long-term evidence actually looks like, and from PicnicHealth’s work building infrastructure designed specifically for this problem.
