A clinical study involves research using human volunteers (also called participants) that is intended to add to medical knowledge. There are two main types of clinical studies: clinical trials (also called interventional studies) and observational studies. ClinicalTrials.gov includes both interventional and observational studies.
Guides developed the National Institutes of Health (NIH) to help people learn more about clinical trials, why they matter, and how to participate.
The site provides information about clinical trials running in the UK. It is designed to enable you and your clinician to locate and contact trials of interest to you
