Clinical trials for breast cancer

Breast cancer trials are usually organized around the tumor's subtype: hormone-receptor status and HER2. Trials differ a great deal between early-stage and metastatic disease, so the stage matters when you read eligibility.

Data from ClinicalTrials.gov, retrieved 2026-07-13. These are trials worth asking your care team about, not a determination that anyone qualifies. Eligibility is decided by the trial's own doctors.

Refine for your situation

Add whatever you know: an age, a city, a mutation from a pathology report. We'll narrow the list to trials that fit. Describe it in your own words.

Whatever you have: the diagnosis, a mutation if you know it, age, where you live.

Common questions

Is this breast cancer trial finder really free?
Yes. You describe the situation, we search ClinicalTrials.gov and show what matches. No account, no payment, no email required. Nothing you type is saved.
Does showing up here mean the patient qualifies?
No. These are trials worth asking your care team about. Every trial has detailed eligibility criteria that the trial's own doctors evaluate, and many depend on test results and treatment history that only your medical team knows in full.
How current is this list?
The trials come directly from ClinicalTrials.gov and are refreshed daily. Each result links to the full, live study record, and the finder above always runs a fresh search when you use it.
What should I do with a trial that looks promising?
Bring it to your oncologist or care team, and mention the NCT number (the ID that starts with NCT). They can tell you whether it is a genuine fit and refer you to the trial site.

Found trials worth discussing? Keep them next to the records.

The next step is a conversation with the care team, and that goes better when the scans, labs, and trial details live in one place everyone in the family can see. That's what KeptWell is: the binder, but it understands what's inside.
