Study Participants

Clinical Study involves research using human volunteers that is intended to add to medical knowledge. In a clinical trial, participants receive interventions may be medical products, such as drugs or devices; procedures; or changes to participants’ behavior, for example, diet.

Clinical trials may compare a new medical approach to a standard one that is already available or to a placebo that contains no active ingredients or to no intervention. Some clinical trials compare interventions that are already available to each other.

Every clinical study is led by a principal investigator, who is often a medical doctor. Clinical studies also have a research team that may include doctors, nurses, social workers, and other healthcare professionals.

Clinical trials that are well-designed and well-executed are the best approach for eligible participants to:

• Play an active role in their own health care.
• Gain access to new research treatments before they are widely available.
• Obtain expert medical care at leading health care facilities during the trial.
• Receive study-related visits, medical evaluations, and study drug at no cost.
• Help others by contributing to medical research.
