The Call for Ethical Clinical Trials in Developing Countries has been formulated out of concern about the shift in many clinical drug trials away from the richer nations and towards developing countries, and the associated ethical violations. It represents a call to action for policy makers, regulators and pharmaceutical companies to protect vulnerable trial subjects and it has been signed by leading figures in the field of medicine and ethics, and other concerned parties. The call was drafted by a worldwide coalition of health and human rights organizations and experts led by the Wemos Foundation.
