The decline in trials in 2009 in Argentina, and many other South American nations, coincides with a widespread downturn in the pharmaceutical and contract research sectors. Total trials initiated in South America fell from 938 in 2008 to 849 in 2009.
Brazil and Peru were the only South American countries where clinical trial initiation continued to increase in 2009. With 443 trials initiated in 2009, up from 408 a year previously, Brazil is the dominant presence in the South American trials market.
Despite clinical trial initiation falling year-on-year from 108 to 91 in 2009, Chile still had the most studies per 1m in population.
Between 2004 and 2005 there is a large leap in the number of clinical trials initiated. This change is underpinned by a number of factors related to submission of information to ClinicalTrials.gov which are discussed here .
Data was collated from ClinicalTrials.gov by Outsourcing-Pharma. The datasets used in these visualisations 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 South American countries from 2000 to 2009.
