4 4 Ethical and Scientific Rationale for Increased Clinical Trial Transparency Subjects put themselves at risk Subject’s right to be informed –All available options, including ongoing trials –Previous research, including completed trials Avoid redundant trials Support Evidenced-Based Medicine (EBM) Detect reporting problems –Lack of publication –Unexplained changes to protocol

5 5 Recent Events: Lack of Transparency in Clinical Research

7 7 The investigation was launched following concerns… …although the ENHANCE trial ended in April 2006, the data had not yet been released. …[the sponsors] did not register the clinical trial in a timely manner. …[the sponsors] attempted to change the study endpoints, and thus the study results, prior to the public release of the results.

10 10 Prospective registry Interventional and observational “trials” –Approved by IRB (or equivalent) –Conform to regulations of national health authorities All sponsor types All intervention types Summary of key protocol items –Consistent with ICMJE and WHO Links to publications, other info Does not include unpublished results

13 13 Characteristics of Web-based registration system (PRS) Register through organizational accounts –Key part of validation XML data upload (<20% records) Data are dynamic—”data provider” can modify data at any time –Changes are tracked
