Registration and Reporting of Clinical Trial Results

What is is a publicly available registry and results database of federally and privately supported clinical trials conducted in the United States and around the world. The purpose of is to disclose to the public key information about clinical trials that are currently available, or were previously conducted. captures summary protocol information before and during the trial, as well as summary results and adverse event information of a completed trial. Federal laws, regulations and editors of prominent medical journals require registration of a clinical trial, as described below.

Do you need to comply with this requirement?

An LSUHSC-NO investigator who conducts a clinical trial must comply with these requirements if:

  • She or he is the Principal Investigator (PI), AND


  • The study is investigator-initiated (the clinical trial is not an industry trial in which the protocol is developed, owned, and sponsored by a company. Industry sponsors are responsible for registering their trials.)

What kind of studies need to be posted on and when?

See the table below for a summary of registration requirements:

The information posted on must be updated throughout the course of the trial, verified at least every 12 months, and the results must be provided when the study ends.

Important note: Even if your investigator-initiated clinical trial does not meet the NIH or FDA clinical trials registration requirements, you are strongly advised to read and consider registering your trial to comply with the following additional requirements:

What else should you consider?

Multi-site clinical trials:
The lead PI for the entire study is the individual responsible for complying with the requirements. If the LSUNO investigator is the PI solely for the LSUNO site and is not the primary awardee or lead study PI, then the LSUNO PI is not responsible for posting to

IND, IDE, HDE trials:
The holder of any IND, IDE, or HDE from the FDA must ensure compliance.

NIH-funded trials:
The primary awardee must ensure compliance.
