Clinical trials—also called research studies—are carefully designed studies that involve people. They help doctors and scientists learn more about health conditions and explore new ways to detect, treat, and prevent disease. People choose to join clinical trials to contribute to research, support future patients, and sometimes gain access to potential new treatments.

Each study has a different purpose. Some focus on testing new medications, devices, or procedures, while others are observational and simply track health patterns or behaviors over time.

Safety is a top priority in all clinical trials. Every study is reviewed by an independent committee called an Institutional Review Board (IRB). This group—made up of doctors, scientists, and ethicists—ensures that the potential benefits outweigh the risks and that the study follows strict ethical guidelines.Before joining, you’ll be fully informed about the study’s details, including any potential risks, so you can make the decision that’s right for you.

People take part in clinical research for many reasons. Some of the potential benefits include:

• Access to investigational treatments before they’re widely available
• Extra attention and care from experienced medical professionals
• The chance to contribute to progress in care for people with similar conditions

It’s important to ask questions and consider things like:

• How long the study will last
• What your participation will involve
• If there’s a chance you’ll receive a placebo
• The potential benefits and risks
• Any travel or time away from daily routines
• Whether your current treatment will change
• If there are any costs—or if compensation is provided
