Prospective registration of clinical trials

What is this about?

Trial registration is the publication of information about the design, conduct, and administration of clinical trials and should be registered before enrollment of the first participant. The information should be published on a publicly-accessible website at no charge, managed by a nonprofit organization, freely available to anybody and searchable electronically. Registration aims to 1) improve the transparency of these trials and to 2) protect stakeholder interests – including the interests of the subjects, the investigators, peer scientists and society in general.

Why is this important?

Those responsible for conducting clinical trials sometimes fail in their ethical obligations towards subjects, sponsors, the scientific community and the general public by not publishing study outcomes in a timely manner. Some do not make results available at all[i]. Problems surrounding the reporting of research outcomes could lead to an erosion of trust in clinical trials. Subjects feel their contribution is not respected, harms are not adequately managed, and taxpayers feel their money is misspent. A failure to report all of the outcomes of research also slows the pace of scientific development. The regulatory policies demanding clinical trials’ registration in advance of the purposed beginning of the study aim to address and mitigate these problems.

The registration of all interventional trials is considered to be a scientific and ethical responsibility. The Declaration of Helsinki states that "Every clinical trial must be registered in a publicly accessible database before recruitment of the first subject". The trials registration offers the following advantages: 1) ensure global access to scientific data;2) prevent unnecessary duplications, informing about similar or identical trials and therefore saving public resources;3) offer to patients the possibility of being recruited in an experimental study;4) facilitate the identification of publication bias and selective reporting;5) allow investigators to increase the quality of research design;6) support international scientific cooperation by enabling researchers and health care practitioners to identify trials in which they may have an interest;and 7) reduce the tendency to under-report negative findings.(1)
