Clinical Trial Website Registration Requirements

Information on

Clinical trial registration is required by both the Food and Drug Administration Amendments Act (FDAAA) and International Committee of Medical Journal Editors (ICMJE). Meeting FDAAA requirements satisfies federal regulations. Meeting ICMJE requirements satisfies many journals’ publishing requirements. Registering your study on satisfies FDA and ICMJE requirements for making trial information available to the public. Registering a study is only the first step. There are additional requirements over the life of the study. ICMJE requirements include a broader range of studies that need to be registered. Pay close attention to the key points listed in the table below to determine if your trial needs to be registered. Contact Kevin Smilor ( at the CRA if you:

  1. Need help determining if your trial needs to be registered
  2. Need help determining if you are the person responsible for the registration (are you the IND/IDE holder? Are you the Grant awardee? Did you initiate the study? Are you the PI who is responsible for conducting the trial AND has control over data AND has rights to publish results?)
  3. Have any other questions about registering your study on
