When research may be worth considering, and how to tell if a trial fits.
Trials may be worth asking about at diagnosis, before or after a specific treatment line, when standard options are limited, no longer working, not tolerated, or when a trial is appropriate before a treatment decision. Eligibility depends on cancer type, past treatments, and the study’s rules — not on advertising claims.
When a trial may be worth considering
- Your doctor mentions a trial as an option.
- Standard treatments haven't worked, or haven't fully worked, for you.
- You want access to a newer therapy that isn't yet standard of care.
- You're interested in contributing to research while getting care.
How to tell if a specific trial fits
Eligibility
Most trials have a specific list of who can and can't enroll. We check eligibility for you in plain language.
Location and logistics
How often you'd need to travel, whether visits can be virtual, and what's covered.
What the trial is testing
A new drug, a combination, a device, or a behavioral approach — each has different implications.
Phase
Earlier-phase trials usually focus on safety and dosing; later-phase trials compare against existing treatments.
