The International Shift in Clinical Trials

Why Global Data Is More Critical Than Ever

Over the past two decades, clinical research has shifted dramatically. What was once a primarily U.S.-centric model is now a truly international ecosystem. This global expansion brings opportunity and complexity, reshaping how clinical teams plan studies, select sites, and identify investigators.

Today’s trials routinely span multiple countries, each with unique regulatory requirements, patient populations, site capabilities, and investigator networks. In this white paper, H1 analyzes 25 years of clinical trial data to reveal how and where trials are going global—from the rise of Europe as a unified research powerhouse to China’s rapid growth across all phases, and the increasing participation of diverse markets worldwide. It also explores what this means for modern feasibility and site selection strategies.
