Specialists in Japanese & ethnic bridging studies

Bridging studies are comparative clinical studies carried out to determine the safety and efficacy of a new medicine in different ethnic populations, for example, Japanese and Caucasian populations. It is important to understand these geographic variations in order to accelerate the drug development process and bring medicines to the market faster.


We are Europe's longest established provider of Japanese and Ethnic Bridging Studies. We are based in two acute NHS Teaching Hospitals in the greater London area, St. George’s University Hospital and Croydon University Hospital (formerly Mayday University Hospital).
