A clinical trial is a scientific study that determines if medications or treatments works for people, and how it works.

Clinical trials are also often called clinical studies or clinical research.

Clinical research helps answer specific questions about investigational drugs. An investigational drug is a medicine that is being investigated before it hits the market. Some of the questions the clinical research tries to answer are:

  • Is the drug effective?
  • Is it more effective than another treatment that is already established?
  • Is it safe, and what are the potential side effects?

The development of a new medicine takes on average 10 years. This might seem like a very long time, but it’s important to take the time needed to make sure that every new medicine or treatment is tested properly and deemed safe to use.
