Is data obtained from clinical studies in Colombia sufficiently shared?

According to ClinicalTrials.gov there are 712 studies registered for Colombia as a location for patient recruitment (Data search: December 5 2013). Most of these trials were designed to evaluate the safety and effectiveness of approved drugs in off-label conditions in postmarketing studies (phase IV) and to test investigational new drugs (clinical trials, phases one to three). The majority of ClinicalTrials.gov studies are multicentric phase III clinical trials, with patients are recruited in Colombian cities as well as other locations around the world. Approximately four out of ten studies registered in this clinical trial platform are not published after three years or more of the study completion date (Table 1).
