Requirements for Registering with Clinicaltrials.gov

Do I need to register with Clinical Trials.gov?

FDA Required Registration: The Food and Drug Administration (FDA) requires study registration along with results and adverse event reporting for all phase II - IV interventional drug, biologic or device trials ("applicable clinical trials"). “Applicable Clinical Trials” include the following:

  • Trials of drugs or biologics: controlled clinical investigations, other than phase 1 clinical investigations, of drugs or biological products subject to FDA regulation. Registration may be required for drugs and devices even if an IND or IDE is not required.
  • Trials of devices: 1) controlled trials with health outcomes of devices subject to FDA regulation, other than small feasibility studies, and 2) pediatric post-market surveillance required by FDA.

National Institutes of Health Registration:The NIH encourages registration and results reporting for all NIH-supported clinical trials, regardless of whether or not they are subject to FDAAA. Grant awardees MUST register if their study includes:

Examples include: drugs/small molecules/compounds; biologics; devices; procedures (e.g., surgical techniques); delivery systems (e.g., telemedicine, face-to-face interviews); strategies to change health-related behavior (e.g., diet, cognitive therapy, exercise, development of new habits); treatment strategies; prevention strategies; and, diagnostic strategies.

International Committee of Medical Journal Editors' Requirements: Publication of interventional health outcome studies in journals adhering to the International Committee of Medical Journal Editors' (ICMJE) Uniform Requirements for Manuscripts Submitted to Biomedical Journals is contingent on timely study registration. A study requires registration for ICMJE purposes if it involves the prospective assignment of subjects to a health-related intervention that investigates the cause-and-effect relationship between the health-related intervention and any health outcome.
