A clinical research study helps researchers and doctors find new or better ways to understand, detect, control, and treat human diseases. For example, a clinical research study might be conducted to identify what causes people to get a disease or test whether a new treatment, surgical procedure, or lifestyle change can cure or prevent a disease.
Clinical trials provide many benefits to you.
The benefits depend on the particular study in which you participate. The largest benefit, by far, is that you are helping others with similar conditions by contributing to health research. Other benefits may include:
All clinical research studies have guidelines, called inclusion/exclusion criteria, that determine who can participate. These guidelines are based on factors such as age, type of disease, medical history, current medical condition, and exposure history. These criteria are used to identify appropriate participants and keep them safe, as well as ensure researchers will be able to answer the questions being asked.
Some clinical research studies are purely observational. Although the volunteers may be required to donate a blood specimen or undergo a diagnostic procedure, no treatment will be given to change the course of their disease. In this type of study, data will be collected from the volunteers through clinical testing or questionnaires. The data will be analyzed to determine what caused the disease or why some people are more likely to develop it than others. Blood is often collected to test for a genetic predisposition for the condition. Examples of some of the types of data that maybe collected for an observational clinical research study include family, medical, occupational and geographical history, ethnicity, toxicant exposure, diet, and lifestyle.
A clinical trial is a clinical research study that involves studying a drug, new medical procedure, or device. For example, a clinical trial may test the effectiveness of a new drug for treating diabetes or asthma. Many new drugs are found to be effective in animal tests done in a research lab. However, drugs, procedures, and devices must be proven to be safe and effective for people, before they can be routinely used in people. That is where volunteers in clinical trials come in.
There is risk in all clinical research. The informed consent process allows you to learn the facts about a clinical research study, before you decide to participate. The facts include why the research is being done, what the researchers want to accomplish, what will be done during the study and for how long, what risks are involved, what benefits can be expected, and what other treatments are available. A written consent form will explain your rights as a research participant, and describe how your privacy will be protected during the study.
