A Clinical Trial is the scientific term for a test or study of a drug or a medical device (defined as any treatment not ingested by the body) which is carried out with people as subjects. Clinical trials are conducted to see if the treatment is safe and effective for people to use: To see how it compares to existing treatments, or to measure its effectiveness if no current treatment exists.
By taking part in a clinical trial, you will try a new treatment that may or may not be better than those that already exist. But your participation also may lead to eventual improvements in the health of many other patients. To better understand how the treatments may work on different races and genders, it is important that both males and females of diverse ethnic groups, including African Americans, Hispanics/Latinos, American Indians, Asians, Pacific Islanders, and Caucasians, take part in the studies.
Doctors and other health professionals run the tests according to strict rules set by the Food and Drug Administration (FDA) to make sure that people who agree to be in the studies are treated as safely as possible. Many studies require that neither the patient nor the doctor know whether the patient is receiving the study treatment or the standard treatment or a placebo (an inactive substance that looks like the drug being tested). By using this “blind” test method, no outside influence can affect the patient’s reaction to the treatment.
To help you decide if you want to participate in a study, FDA requires that you be given complete information about the study before you agree to take part. This is known as informed consent. FDA requires that people be told:
Before you can be in the study, you must sign the informed consent form, showing that you have been given this information and it must be written so you can understand it. If you don't, be sure to ask the doctor or other medical person to explain it. Make sure you understand all of it before you agree to be in the study.
