What is clinical research?

Clinical research refers to studies in which people participate as patients or volunteers. Different terms are used to describe clinical research, including:

  • clinical studies
  • clinical trials
  • studies
  • research
  • trials
  • protocols.
Clinical research may have a number of goals, such as:
  • developing new treatments or medications
  • identifying causes of illness
  • studying trends
  • evaluating ways in which genetics may be related to an illness.

The idea for a clinical research study—also known as a clinical trial—often originates in the laboratory. After researchers test new therapies or procedures in the laboratory and in animal studies, the most promising experimental treatments are moved into clinical trials, which are conducted in phases. During a trial, more information is gained about an experimental treatment, its risks, and its effectiveness.

Strict rules for clinical studies have been put in place by National Institutes of Health and the FDA. Some studies involve promising new treatments that may directly benefit participants. Others do not directly benefit participants, but may help scientists learn better ways to help people.

Confidentiality is an important part of clinical research and ensures that personal information is seen only by those authorized to have access. It also means that the personal identity and all medical information of clinical trial participants is known only to the individual patient and researchers. Results from a study will usually be presented only in terms of trends or overall findings and will not mention specific participants.

Clinical research is much different from the medical treatment you receive in a Healthcare Provider’s office.

Who should consider clinical trials and why?

Some people participate in clinical trials because none of the standard (approved) treatment options have worked, or they are unable to tolerate certain side effects. Clinical trials provide another option when standard therapy has failed. Others participate in trials because they want to contribute to the advancement of medical knowledge.

All clinical trials have guidelines, called eligibility criteria, about who can participate. The criteria are based on such factors as age, sex, type and stage of disease, previous treatment history, and other medical conditions. This helps to reduce the variation within the study and to ensure that the researchers will be able to answer the questions they plan to study. Therefore, not everyone who applies for a clinical trial will be accepted.

It is important to test drugs and medical products in the people they are meant to help. It is also important to conduct research in a variety of people, because different people may respond differently to treatments.  FDA seeks to ensure that people of different ages, races, ethnic groups, and genders are included in clinical trials. Learn more about FDA’s efforts to increase diversity in clinical trials.

Where are clinical trials conducted?

Clinical trials can be sponsored by organizations (such as a pharmaceutical company), Federal offices and agencies (such as the National Institutes of Health or the U.S. Department of Veterans Affairs), or individuals (such as doctors or health care providers). The sponsor determines the location(s) of the trials, which are usually conducted at universities, medical centers, clinics, hospitals, and other Federally or industry-funded research sites.

Are clinical trials safe?

FDA works to protect participants in clinical trials and to ensure that people have reliable information before deciding whether to join a clinical trial. The Federal government has regulations and guidelines for clinical research to protect participants from unreasonable risks. Although efforts are made to control the risks to participants, some may be unavoidable because we are still learning more about the medical treatments in the study.

The government requires researchers to give prospective participants complete and accurate information about what will happen during the trial. Before joining a particular study, you will be given an informed consent document that describes your rights as a participant, as well as details about the study, including potential risks. Signing it indicates that you understand that the trial is research and that you may leave at any time. The informed consent is part of the process that makes sure you understand the known risks associated with the study.

What should I think about before joining a clinical trial?

Before joining a clinical trial, it is important to learn as much as possible. Discuss your questions and concerns with members of the health care team conducting the trial. Also, discuss the trial with your health care provider to determine whether or not the trial is a good option based on your current treatment. Be sure you understand:

  • what happens during the trial
  • the type of health care you will receive
  • any related costs once you are enrolled in the trial
  • the benefits and risks associated with participating.
What is FDA’s role in approving new drugs and medical treatments?

FDA makes sure medical treatments are safe and effective for people to use. We do not develop new therapies or conduct clinical trials. Rather, we oversee the people who do. FDA staff meet with researchers and perform inspections of clinical trial study sites to protect the rights of patients and to verify the quality and integrity of the data.

Where can I find clinical trials?

One good way to find out if there are any clinical trials that might help you is to ask your doctor. Other sources of information include:

  • FDA Clinical Trials Search. Search a database of Federally and privately supported studies available through clinicaltrials.gov. Learn about each trial’s purpose, who can participate, locations, and who to contact for more information.
  • Clinicaltrials.gov. Conduct more advanced searches
  • National Cancer Institute or call 1–800–4–CANCER (1–800–422–6237). Learn about clinical trials for people with cancer.
  • AIDSinfo. Search a database of HIV/AIDS trials, sponsored by the National Institutes of Health’s National Library of Medicine.
What is a placebo and how is it related to clinical trials?

A placebo is a pill, liquid, or powder that has no treatment value. It is often called a sugar pill. In clinical trials, experimental drugs are often compared with placebos to evaluate the treatment’s effectiveness.

Is there a chance I might get a placebo?

In clinical trials that include placebos, quite often neither patients nor their doctors know who is receiving the placebo and how is being treated with the experimental drug. Many cancer clinical trials, as well as trials for other serious and life-threatening conditions, do not include placebo control groups. In these cases, all participants receive the experimental drug. Ask the trial coordinator whether there is a chance you may get a placebo rather than the experimental drug. Then, talk with your doctor about what is best for you.

How do I find out what Phase a drug is in as part of the clinical trial?

Talk to the clinical trial coordinator to find out which phase the clinical trial is in. Learn more about the different clinical trial phases and whether they are right for you.

What happens to drugs that don’t make it out of clinical trials?

Most drugs that undergo preclinical (animal) research never even make it to human testing and review by the FDA. The drug developers go back to begin the development process using what they learned during with their preclinical research. Learn more about drug development.
