What Are Clinical Trials?
Clinical trials are research studies that involve people. They
are the final step in a long process that begins with research
in a lab and animal testing. Many treatments used today are
the result of past clinical trials.
In cancer research, clinical trials are designed to answer
questions about new ways to:
- Treat cancer
- Find and diagnose cancer
- Prevent cancer
- Manage symptoms of cancer or its treatment
This booklet will focus on cancer treatment studies. These
studies are designed to answer questions about new
treatments or new ways of using an old treatment and how
well they work. These trials test many types of treatments,
such as new:
- Drugs or vaccines
- Ways to do surgery or give radiation therapy
- Combinations of treatments
Many treatments used today are the results
of past clinical trials.
