Clinical Trials
Find resources to help explain what it means to participate in a clinical trial — an important first step for people considering volunteering.
An idea for a clinical trial often starts in a lab. After researchers test new treatments or procedures in a lab, the most promising treatments are moved into clinical trials. As possible new treatments move through a series of steps called phases, more information is gained about the treatment, its risks, and how effective it is.

Clinical research, including clinical trials, have led to or improved every vaccine and treatment available today.

Joining a research study or clinical trial is completely voluntary, and you may leave a study at any time for any reason.

Clinical trials and clinical research studies conducted today have safeguards in place to protect the safety and rights of everyone who volunteers.
