In brief
Phase 1 cancer trials are usually early studies. They often focus on safety, side effects, dose, and whether a treatment has enough signal to study further.
What this kind of result can tell you
A small phase 1 result can show that researchers found a dose to study, saw expected or unexpected side effects, or saw early signs of activity in some participants. It can be important without proving a treatment should become standard care.
What this does not mean
- It does not prove the treatment is better than standard care.
- It does not prove long-term benefit.
- It does not mean the treatment is available outside a trial.
- It does not mean the result applies to people who would not meet the trial's eligibility criteria.
Questions patients can ask
- Was the main purpose safety, dose-finding, response, or comparison with standard treatment?
- How many people were treated at the dose being discussed?
- What serious side effects occurred, and how were they managed?
- Were responses confirmed on later scans?
- Is there a phase 2 or phase 3 trial, and what are the eligibility rules?
