Find recruiting clinical trials

What the tool shows

ClinicalTrials.gov is a searchable registry and results database of publicly and privately funded clinical trials conducted in the United States and around the world, showing each trial's purpose, who may participate, its locations and contact numbers.

The tool shows studies whose status in the registry is "recruiting" or "not yet recruiting", and the data come at the moment of search from the ClinicalTrials.gov application programming interface (version 2).

Before you consider taking part

Before taking part in any study, talk to a healthcare provider and learn about its potential risks and benefits; this information is used alongside professional advice, not in place of it.

Informed consent is the process of giving you the key information about the study before you decide; most trials in the United States — not all — are approved and monitored by institutional review boards (IRBs).

Know the trial's phase and what question it is trying to answer; see Clinical trial phases.

How to use it

Type the name of the condition in English (such as type 2 diabetes or asthma), or choose a name from the suggested list taken from the encyclopedia's pages, then choose a country if you wish and press "Search".

When you press the button, your browser sends only the search term and the chosen country directly to ClinicalTrials.gov, and the request does not pass through the Medi.kharousi server or get stored there; and as with any request over the internet, technical information such as your device's IP address reaches the service. Do not type any personal data in the search box.

Limits of the tool

A study being listed in ClinicalTrials.gov does not mean the US federal government has evaluated it.

The tool does not nominate you for any study and does not assess its suitability for you; the conditions for participation and the locations are in each study's registry entry, and the decision to take part is made with your doctor.

There are other trial registries recognised by the WHO that can be searched through the ICTRP platform at trialsearch.who.int.

Titles and data are shown in English as they are in the registry, and the registry's own search engine chooses the results and their order.
