Some pharmaceutical companies and device manufacturers make trial information available through their own website. A number of these pharmaceutical and device industry registers are listed on Clinical Trials Registers, Databases and Portals. You can also go directly to the website of the manufacturer of a product you're interested in to see if information is available, and contact them for further information if required.
In some cases trial information may be published on the web as reports or other documents. See our information on searching the internet for grey literature.
