Trials in developing countries.

Good clinical trials can be carried out in the developing countries but ethical issues concerning the trials are frequently brought up for international debate. The concern has its own merit but can be amended if investigators (local and international) pay serious attention to these criticisms and work out the way that will most benefit the trial participants. Although scientific progress is important, it must come after the rights, the safety and the benefit of the patients. Frequently, the ethical standard is delicately balanced, depending on who looks at it and from what angles they look. Critics, investigators, volunteers, sponsors and regulatory agencies have their own mandates, expectations and limitations, and thus they need to keep an open line of communication in order to benefit all parties involved.
