Clinical Trials

What is a Clinical Trial?

A clinical trial is the scientific term for the step-by-step process that studies or tests in humans a new procedure, drug, vaccine, or device. Each trial seeks to answer specific questions with the goal of finding better ways to prevent, screen for, make diagnoses, or treat a disease.

Why Clinical Trials?

Many of today’s life-saving treatments are based on yesterday’s clinical trials. Advances in hypertension, diabetes, cancer, and heart failure have been powered by clinical trials.

Why Minorities and Clinical Trials?

African Americans and other minorities are underrepresented in important medical research to find treatments for the very diseases that affect them such as diabetes, hypertension, HIV/AIDS, and lung cancer. Optimal health depends on knowing whether a treatment affects women or men differently, or affects a racial/ethnic minority differently.

How do I find clinical trials being conducted at Johns Hopkins Medicine?

All clinical trials at Johns Hopkins are listed at, a registry and results database of publicly and privately supported clinical studies of human participants conducted around the world.
