RSS Feeds

RSS allows you to receive information and updates from a Web site. This page explains how to set up RSS feeds that will notify you of new study information on ClinicalTrials.gov. Subscribing to an RSS feed saves you time because you will not have to check each study record in your search results for updates.

RSS feeds can provide updates to the results of a specific search, on all recently added study records, or on all recently modified studies. The RSS feed will automatically list additions and updates to your search results in either your Internet browser or a feed reader (see How to Subscribe to a Feed).

RSS Feed for a Specific Search

Creating an RSS feed for a specific search allows you to easily access and browse study records meeting your search criteria that have been first posted or last update posted in the last 14 days. To create the feed from the Search Results page, follow the instructions provided in the example below.

How to Subscribe to a Feed

To read the RSS feed updates, you need a reader, also called an aggregator. Readers can be Web based (for example, Google Reader), part of your browser (for example, Microsoft Internet Explorer, Mozilla Firefox), part of your e-mail client (for example, Microsoft Outlook), or installed on your computer. Web-based and e-mail client readers let you read RSS feeds from any computer. Feed subscriptions in your browser or reader software installed on your computer will be available only on the computer used to subscribe to the feeds.

Subscribe to a Feed Using Your Internet Browser

The steps below describe how to subscribe to an RSS feed using MS Internet Explorer or Mozilla Firefox. The process may be slightly different for other browsers. Refer to your browser's help files for more information.

In your browser, create or open the RSS feed that you want to subscribe to. (See the instructions for creating an RSS Feed for a Specific Search.) To create an RSS feed for all studies on ClinicalTrials.gov, do not enter any words in the search boxes, click on Search or Search all studies (depending on which page you are on).

Alternative to RSS Feeds

Instead of subscribing to an RSS feed, you can use your browser to bookmark a Search Results page or label it as a "favorite." For example, a bookmarked Search Results page for studies on anticonvulsants recruiting in Chicago would appear as "Search of: Recruiting Studies | Anticonvulsants | United States, Illinois | Chicago - List Results - ClinicalTrials.gov" in your list of bookmarks or favorites. Each time you visit the page, you will see all the current results for your search, including records that have been recently added or updated and records that have not changed.
