Clinical trials are scientific studies which require the participation of volunteer patients.
Before any new medicine or medical device is placed on the market, it must be tested through clinical trials. Results are then reviewed to determine if the drug, practice or medical device should be made available to the public. Clinical trials are a vital part of scientific research that play an important role in the research and evaluation of new medicines and treatments. They bring medical research one step closer to effective treatments and cures. Potential benefits vary according to each trial, and no guarantee can be given of any benefit, but there are some common advantages to being part of a clinical trial.
