Trials answer research questions
Joining a trial does not guarantee that a treatment will work. It also does not guarantee a cure. Ask what is already known and what is still unknown.

Plain-language reminder
What a Clinical Trial Can and Cannot Promise
A clinical trial may give someone access to care or a treatment being studied, but the main purpose of a clinical trial is to answer a research question. Use the clinical trial glossary if a term feels unfamiliar.
Trials can study different things
Some trials compare treatments. Some include a clinical trial control group. Others study side effects, quality of life, screening, prevention, or supportive care.
You can ask before deciding
Ask what other options are available, what participation may involve, and whether you can take the consent form home before making a decision. You can also bring questions to ask your doctor.
