Observational clinical trials are conducted to gain information from patients with a specific diagnosis or patients receiving specific treatment.
Many clinical trials are for observation purposes only. Before a new treatment is tried with patients, it is carefully studied in the laboratory. This research points out the new methods likely to succeed and, as much as possible, shows how to use them safely and effectively. But this early research cannot predict exactly how a new treatment will work with patients.
Only those patients who wish to participate take part in the clinical trial. You may be interested in or asked to enter a trial. Learn as much as you can about the trial before you make up your mind. You will be given a consent form to review and have all of your questions answered before deciding to participate in a clinical trial.
