What Is a Clinical Trial and What Can Patients Expect?

A clinical trial is a research study that helps doctors learn better ways to prevent, diagnose or treat disease. Clinical trials test new medications, medical devices or treatment approaches to make sure they are safe and effective for patients. Many of the treatments used in health care today are available because patients chose to participate in clinical trials.

If you take part in a clinical trial, you will receive care from a dedicated research team that may include physicians, nurses and study coordinators. Before enrolling, you’ll be given detailed information about the study, including its purpose, how long it lasts, what procedures are involved and any potential risks or benefits. This process—called informed consent—gives you the opportunity to ask questions and decide whether participation is right for you.

During the trial, you may have additional visits, tests or follow-ups compared to routine care. These steps help researchers carefully monitor your health and track how the treatment works. Your safety is always a top priority, and clinical trials follow strict guidelines to protect participants.

Participation is always voluntary. You can choose to leave a clinical trial at any time, for any reason, without affecting your regular medical care.

By joining a clinical trial, patients play an important role in advancing medicine. Participation may provide access to new therapies and helps improve care for future patients. If you’re interested in a clinical trial, talk with your health care provider or research team to learn more about your options.
