  • 摘要:Background Selective clinical trial publication and outcome reporting has the potential to bias the medical literature. The 2007 Food and Drug Administration (FDA) Amendment Act (FDAAA) mandated clinical trial registration and outcome reporting on ClinicalTrials.gov, a publicly accessible trial registry. Methods Using publicly available data from ClinicalTrials.gov, FDA documents, and PubMed, we determined registration, publication, and reporting of findings for all efficacy trials supporting FDA approval of new drugs for cardiovascular disease and diabetes between 2005 and 2014, before and after the FDAAA. For published trials, we compared the published interpretation of the findings (positive, equivocal, or negative) with the FDA reviewer’s interpretation. Results Between 2005 and 2014, the FDA approved 30 drugs for 32 indications of cardiovascular disease ( n = 17) and diabetes ( n = 15) on the basis of 183 trials (median per indication 5.7 (IQR, 3–8)). Compared with pre FDAAA, post-FDAAA studies were more likely to be registered (78 of 78 (100%) vs 73 of 105 (70%); p p = 0.03), and to present findings concordant with the FDA reviewer’s interpretation (74 of 76 (97%) vs 78 of 93 (84%); p = 0.004). Pre FDAAA, the FDA reviewer interpreted 80 (76%) trials as positive and 91 (98%) were published as positive. Post FDAAA, the FDA reviewer interpreted 71 (91%) trials as positive and 71 (93%) were published as positive. Conclusions FDAAA was associated with increased registration, publication, and FDA-concordant outcome reporting for trials supporting FDA approval of new drugs for cardiovascular disease and diabetes.
