A clinical trial involves research participants. All new treatments have to be thoroughly tested. Clinical trials help doctors understand how to treat a particular illness. It aims to explain the facts behind the headlines and give a better understanding of the research that was carried out. You'll often see stories about research findings in mainstream media. Recently, NIH launched a multi-faceted effort to enhance its stewardship over clinical trials with the goal to encourage advances in the design, conduct, and oversight of clinical trials while elevating the entire biomedical research enterprise to a new level of transparency and accountability. Recently, National Institutes of Health (NIH), the largest funding agency of clinical trials in the U.S., changed the “clinical trial” definition.

In a phase 1 clinical trial, the tolerability and safety of the new drug is studied, usually in a small number of healthy volunteers. Clinical trials in the research community are subject to strict ethical and regulatory requirements.

Clinical trials testing potential medical products are commonly classified into four phases. In the early phases, the new intervention is tested in a small number of participants to assess safety and effectiveness. In England and Wales, the National Institute for Health and Care Excellence (NICE) decides whether the NHS should provide treatments.
