There are ethical and legal codes that apply to clinical trials. The trial follows a carefully controlled study plan which details what researchers will do in the study. This plan must first be approved by the Princess Alexandra Hospital Human Research Ethics Committee. The Committee is an independent committee of physicians, a nurse, a lawyer, a pharmacist, a minister of religion, community members and others who ensure that a clinical trial is ethical, that the risks are as low as possible and the potential benefits are worthwhile. The Diamantina Institute also has a Human Ethics Committee at The University of Queensland that may also initially approve and periodically review the research. As a clinical trial progresses, researchers report the results of the trial at scientific meetings, in scientific journals and to various government agencies. Individual participants' names will not be disclosed and will not be mentioned in any of these reports.
