Clinical trials are scientific studies to evaluate new therapies. Drugs, diagnostic procedures, and other therapies are tested in patients to determine if they are safe and effective. Clinical trials move research forward and help improve the quality of treatments available to patients.

Clinical trials are categorized by phase:

early phase or phase I trials evaluate the safety of new therapies;

phase II trials evaluate efficacy;

and phase III trials compare new therapies to existing standard therapies.
