A placebo is an inactive substance, which may be given to some of the study participants in a clinical trial as a control, so that researches can verify that any results can be attributed to the drug being tested assist in comparing the effects of the active study treatment.

When a drug company wants to license a new drug, the United States Food and Drug Administration (FDA), the European Medicines Agency, and other regulatory authorities require that the drug be tested on a large number of patients to make sure the drug is both safe and effective. The company must then select a number of medical research centers or clinics around the country that can recruit appropriate participants for the study.

Clinical trials are important to ensure individuals receive safe and effective treatments for their health conditions, from heart disease to headaches. They provide the means to develop new treatments that are as effective, more effective, or safer than treatments already on the market; they enable researchers to discover new therapeutic uses for currently available medications, and they make it possible to develop innovative treatments for conditions that currently have no treatment.

There’s no cost for joining a clinical trial. Study medication, as well as study-related tests and procedures are usually provided at no charge to study participants. In some cases, you may be compensated for your time and travel expenses related to study participation.

In the interest of safety, the participant must fully inform the study physician about past and current medical conditions, illnesses, and medications, follow the prescribed treatment plan and attend scheduled visits. Study personnel will explain other study-specific responsibilities.

Informed consent is the process by which a potential study participant agrees to participate in a trial after being provided with information about the study and treatment. It includes an explanation of what’s involved in the trial, the duration of the study, the frequency and length of the required visits, as well as the known risks and benefits associated with the study treatment.

Participation in a clinical trial is completely voluntary. All questions about the study should be answered to the participant’s satisfaction before an informed consent form (ICF) is signed. Participants have the right to refuse participation or to withdraw their consent at any time during the study without penalty.

The wishes and best interest of the participant are considered at all times. Throughout the trial, participants will be provided with any new information that may affect their decision to continue their involvement in the study. In addition, the study physician may withdraw a participant at any time, without consent, if it becomes evident that it’s not in their best interest to continue.

People participate in clinical trials for various reasons, including health, financial and societal reasons. Volunteers who participate in clinical trials help to further advance medical science, which can help others in the future.

Clinical trials provide volunteers with free health and medical information. In addition, financial compensation for time and travel expenses may be provided to study participants.

Clinical trials are performed around the world in various settings, including doctors’ offices, hospitals, research centers and teaching institutions. Since most trials require periodic visits to the study physician, volunteers should take the location of the facility into consideration when deciding whether to participate in a clinical trial.

Most clinical trials are sponsored by pharmaceutical companies, federal health agencies, medical foundations, medical centers, and universities; however, physicians may sponsor some clinical trials, particularly when the trial evaluates a currently available treatment for a condition other than for what it was previously approved.
