Clinical trials require different types of people. Each type chooses to participate for different reasons.
- Healthy Volunteers
Healthy volunteers play an important role in research because they help define “normal” ranges. While they may receive no direct benefit, healthy volunteers may choose to participate in clinical research because they want to help others and contribute to advancing science.
- Patient Volunteers
People with a health condition or disease may take part in a research study to gain access to a new therapy; take a more active role in their health; or contribute to better understanding, diagnosing, or treating that disease or condition. While some patient volunteers may receive a direct benefit from participating, the overall goal of the clinical trial may be to understand the risks and benefits of a treatment and to scientifically prove whether it is effective.
