About Clinical Trials
Clinical trials are research studies
that involve people. These studies test new ways to prevent, detect, diagnose, or
treat diseases. People who take part in cancer clinical trials have an opportunity
to contribute to scientists’ knowledge about cancer and to help in the development
of improved cancer treatments. They also receive state-of-the-art care from cancer
Possible benefits of taking part in a clinical trial
The benefits of participating in a clinical trial include the following:
- Trial participants have access to promising new interventions that are generally
not available outside of a clinical trial.
- The intervention being studied may be more effective than standard therapy. If it
is more effective, trial participants may be the first to benefit from it.
- Trial participants receive regular and careful medical attention from a research
team that includes doctors, nurses, and other health professionals.
- The results of the trial may help other people who need cancer treatment in the
- Trial participants are helping scientists learn more about cancer (e.g., how it
grows, how it acts, and what influences its growth and spread).
Potential harms associated with taking part in a clinical trial
The potential harms of participating in a clinical trial include the following:
- The new intervention being studied may not be better than standard therapy, or it
may have harmful side effects that doctors do not expect or that are worse than
those associated with standard therapy.
- Trial participants may be required to make more visits to the doctor than they would
if they were not in a clinical trial and/or may need to travel farther for those
- Health insurance may not cover all patient care costs in a trial.
