Ethical considerations of clinical trials in the developing world.

The developing world is entering new territory with rapid advancements in biomedical research and science. In order to ensure the protection of those most vulnerable, bioethics must experience a similar expansion and progression worldwide. Inequalities in healthcare remain an influential issue to redress on a global scale, and may provide an opportunity to induce a paradigm shift in the worldwide approach to medical research. In particular, clinical trials performed in a nation different to that of the sponsoring institution must appreciate any underlying ethical conflict and ensure that the volunteers involved are treated with the best attainable and sustainable standards.
