NIH Definition of Clinical Trials

It is important for UC San Diego investigators to understand NIH’s definition of a Clinical Trial.

The definition includes as clinical trials any studies that involve human participants assigned to an intervention in which the study is designed to evaluate the effect(s) of the intervention on the participant and the effect being evaluated is a health-related biomedical or behavioral outcome.

All NIH-funded clinical trials will be subject to the additional application requirements, registration, oversight and reporting.  While some aspects of the NIH requirements have been in place for some time, the expanded pre-conditions requiring reporting and registration for all studies defined as clinical trials are more recent and are beginning to be communicated through many venues by NIH.   

Two articles from Dr. Michael Lauer, NIH’s Deputy Director of Extramural Research titled “4 Questions for Researchers and Institutions involved in Human Subjects Research” and the more recently published article “’Continuing to Clarify the NIH Definition of Clinical Trials” The first article explains the changes in the definition and provides an opportunity for researchers to post comments through the “Open Mike Blog.” The second one responds to some of the feedback and provides further clarification.
