From 2005 to 2009 61 per cent of US NIH registered trials included at least one study site outside North America. Outsourcing-Pharma presents this, the 2009 downturn in US trials and other data as an interactive visualisation.

Overseas clinical trial sites have become increasingly vital to drug development and this is evident in the visualisations. Using data from ClinicalTrials.gov the visualisations show that in each year from 2005 to 2009 more than 50 per cent of studies used at least one overseas site.

Also displayed by the visualisation is a dip in clinical trial initiation in the US, Canada and Puerto Rico in 2009. This mirrors similar declines seen in South America​ and Central and Eastern Europe (CEE) and Russia​.

Between 2004 and 2005 there is a large leap in the number of clinical trials initiated in all countries. This change is underpinned by a number of factors which are discussed here​.

Data can be viewed here​.

Below is a heat map showing clinical trial initiation per 1m people. Pressing play animates the changes in clinical trial concentration which took place in CEE and Russia​ from 2000 to 2009.
