Registering a study to Clinicaltrials.gov

Health outcome studies must be registered in clinicaltrials.gov
This requirement applies to:

  • All NIH-funded trials such as phase 1 studies or clinical trials of behavioral interventions or non-FDA-regulated products.
  • Clinical trials involving FDA-regulated drug, biologic and device products
  • Any study intended for publication in a journal recognized by the ICMJE

Behavioral interventions are sometimes clinical trials

The Dept of Health and Human Services defines clinical trials as:

“…any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions1 to evaluate the effects on health outcomes2.”

1Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example, drugs, surgical procedures, devices, behavioral treatments, dietary interventions, and process-of-care changes).
2Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events.”


FDA regulated studies are clinical trials

The FDA / NIH and Centers for Medicare/Medicaid (CMS) require study registration for all “applicable clinical trials”.

Applicable Clinical Trials generally include interventional studies (with one or more arms) of FDA-regulated drugs, biological products, or devices that meet one of the following conditions:

  • The trial has one or more sites in the United States
  • The trial is conducted under an FDA investigational new drug application or investigational device exemption
  • The trial involves a drug, biologic, or device that is manufactured in the United States or its territories and is exported for research
