“The ICMJE requires that clinical trial results be published in the same clinical trial depository where the trial is registered. These results are in the form of a short (?500 words) abstract or table (6,7). Full disclosure of the existing results publication in a clinical trial registry should be explicitly stated when the manuscript is submitted for publication. The Food and Drug Administration (FDA) has indicated it will enforce trial results reporting related to ClinicalTrials.gov (8). The FDA is authorized to seek civil monetary penalties from responsible parties, including additional civil monetary penalties. In the United States, the sponsor of an applicable clinical trial is considered the responsible party, unless or until the sponsor designates a qualified principal investigator as the responsible party. The FDA issued its first Notice of Noncompliance in April 2021 for failure to report results in ClinicalTrials.gov based on a lack of reporting the safety and effectiveness results for the drug dalantercept in combination with axitinib in patients with advanced renal cell carcinoma (8).
Finally, as of July 1, 2018, manuscripts submitted to ICMJE journals that report the results of clinical trials must contain a data sharing statement. Clinical trials that begin enrolling participants on or after January 1, 2019, must include a data sharing plan in the trial registration. (for further information, see www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html). Since most clinical trials take 2 or more years for results to be reported, the Radiology editorial board had expected such mandatory data sharing plans to be reported in the current year. However, because of the COVID-19 pandemic, many clinical trials were halted. Thus, journal publication requirements to include data sharing statements are more likely to impact authors beginning in 2023. Data sharing statements required for Radiological Society of North America (RSNA) journals may be found at https://pubs.rsna.org/page/policies#clinical.
In conclusion, prospective clinical trial registration is a mechanism allowing us to ensure transparency in clinical research conduct, honest and complete reporting of the clinical trial results, and minimization of selective result publications. Since its inception in 2004, this requirement has evolved into a policy that is practiced by major medical journals worldwide, is mandatory for publication of trial results, and, in some circumstances, is enforced by the FDA. Further, ICMJE journals, including RSNA journals, are expecting manuscripts that report trial results to include statements on data sharing. As each clinical trial design is unique, we encourage authors to refer to the full description of the current ICMJE policy at icmje.org for additional information pertaining to their specific circumstances.”
