What Is a Clinical Trial?

Clinical trials are research studies in which people agree to undergo new therapies (under careful supervision) to help identify the best treatments with the fewest side effects. Such trials often help change and shape the landscape of medical care.

There are several types of clinical trials, including treatment trials, prevention (risk reduction) trials, diagnostic trials and quality-of-life trials (which explore ways to improve quality of life for individuals with a chronic illness).

In bariatric surgery, clinical trials are usually treatment-oriented. For example, many surgeons are now looking at whether bariatric surgery can reverse diabetes. Other trials are comparing the outcomes of the various types of available bariatric surgeries.

People who participate in clinical trials can play a more active role in their own health care, gain access to new treatments before they are widely available and help others by contributing to medical research. They typically will get excellent care from the doctors during the course of the study. This care also may be free.

All clinical trials have guidelines about who can participate (inclusion criteria), as well as guidelines that prevent someone from participating (exclusion criteria).

Are Clinical Trials Safe?

Clinical trials have risks. They can include unpleasant, serious or even life-threatening side effects that may be different from the side effects of currently available treatments. What's more, the treatment may or may not be effective, and the design may require more time than traditional care.

Safeguards are in place to protect participants. Every clinical trial in the United States for a new therapy or type of device must be approved by the federal Food and Drug Administration (FDA). In addition, an institutional review board (IRB) approval is also required. These safeguards help make sure the risks of the clinical trial are as low as possible and are worth any potential benefits. If you do decide a clinical trial is the route you'd like to take, informed consent (the process of learning the key facts about a clinical trial before deciding whether to participate) is required.

According to the Office for Human Research Protections, here are some questions to ask if you are considering joining a clinical trial:

  • Why is the research being done?
  • Is the trial FDA-approved?
  • Is the trial IRB-approved?
  • What will be done to me as part of the research?
  • How will I benefit from the research?
  • Could the research hurt me?
  • What will the researcher do with my information?
  • Will the research cost me anything?
  • Who pays if there is a complication?
  • How long will the study last?
  • What happens if I decide to leave the study early?
  • Who should I call if I have a question about the research?
