International ethical guidelines for biomedical research involving human subjects
While some sections remain similar to the 1993 guidance (such as Guideline 7 on inducements to participate in research) others are substantially changed (for example Guideline 5, which outlines essential information for prospective research subjects). A useful aspect of the CIOMS guidance is the commentary provided for each guideline. For example, while the wording of Guideline 11 is similar to section 29 of the Declaration of Helsinki (with an additional proviso), the accompanying four-page commentary provides a useful reflection on the ethical considerations underlying such a stance.
The Guidance is also available in Spanish.
