Clinical trials are medical research studies that can involve patients (people suffering from a certain health condition) or healthy volunteers. They are designed to find out more about a particular condition or to test whether a potential new treatment option could offer greater benefits than the currently available medications or treatments.
Thousands of people around the world take part in clinical research studies every year. The information that is gained in these studies may help others in the future who develop the same condition.
Participation in a clinical research study is completely voluntary and you can change your mind about taking part at any point if you decide that it is not right for you.
