7. Research ethics committees (RECs) have a responsibility to safeguard the rights, safety, dignity and wellbeing of people participating in research. They review applications for research and give opinions about the proposed participant involvement and whether the research is ethical. Guidance on whether research requires ethical review under either the law or the policy of the UK health departments can be found on the National Research Ethics Service website.
8. The Declaration of Helsinki states that ‘The benefits, risks, burdens and effectiveness of a new intervention must be tested against those of the best current proven intervention, except in the following circumstance. The use of placebo, or no treatment, is acceptable in studies where no current proven intervention exists or where for compelling and scientifically sound methodological reasons the use of placebo is necessary to determine the efficacy or safety of an intervention and the patients who receive the placebo or no treatment will not be subject to any risk of serious or irreversible harm. Extreme care must be taken to avoid abuse of this option.’(World Medical Association Declaration of Helsinki, 2008)
9. Restricting research participants to subgroups of the population that may be defined, for example, by age, gender, ethnicity or sexual orientation, for legitimate methodological reasons does not constitute discrimination.
