USDMPlay — Learn CDISC USDM Through Interactive Examples

USDMPlay is a free, independent educational platform for learning CDISC USDM (Unified Study Definitions Model). Upload USDM JSON, explore it as tables and UML diagrams, and try hands-on use cases for Digital Data Flow (DDF).

The Unified Study Definitions Model is CDISC's standard for describing a clinical trial's design — objectives, population, arms, epochs, visits, schedule of activities, and estimands — as structured, machine-readable data instead of a static protocol PDF.
