Page "Clinical trial" Paragraph 101

Different countries have different regulatory requirements and enforcement abilities.

An estimated 40 % of all clinical trials now take place in Asia, Eastern Europe, and Central and South America.

" There is no compulsory registration system for clinical trials in these countries and many do not follow European directives in their operations ", says Dr. Jacob Sijtsma of the Netherlands-based WEMOS, an advocacy health organisation tracking clinical trials in developing countries.
