Spokane, WashingtonAges 18 years+ - NCT06112613Recruiting
Mobile health to help with breast cancer pill-taking
This study uses text messages to help people with metastatic breast cancer remember to take their daily pills and asks about any missed doses. It aims to improve how well patients stick to their CDK4/6 inhibitor medication.

Seattle, WashingtonAges 18 years+ - NCT06757634RecruitingPhase 3
A study of gedatolisib for first-line advanced breast cancer
This trial tests a new targeted therapy called gedatolisib for people with HR-positive, HER2-negative advanced breast cancer who have not yet received treatment for metastatic disease. It aims to see if adding this drug to standard hormone therapy can help control the cancer longer.
Seattle, WashingtonAges 18 years+ - NCT06966453RecruitingPhase 1/Phase 2
Study of disitamab vedotin for HER2-positive advanced breast cancer
This study tests a new drug called disitamab vedotin for people with advanced breast cancer that has a certain amount of HER2 protein. Depending on your HER2 and hormone receptor status, you may be eligible for one of three groups, each with different prior treatment requirements.
Seattle, WashingtonAges 18 years+ - NCT07007559RecruitingPhase 2
Evorpacept with trastuzumab and chemo for HER2+ breast cancer
This trial tests a new drug called evorpacept combined with trastuzumab (Herceptin) and a chemotherapy drug of your choice. It is for people with HER2-positive breast cancer that has spread and who have already tried the drug Enhertu.
Seattle, WashingtonAges 18 years+ - NCT07211178Recruiting
Tracking cancer DNA in blood to detect early return of breast cancer
This study tracks tiny traces of cancer DNA in the blood over time to see if it can find early signs of breast cancer coming back. It looks at different types of breast cancer and at different points in a patient's treatment journey.
Spokane Valley, WashingtonAges 18–99 - NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Seattle, WashingtonAges 18 years+ - NCT05645536Enrolling by invitationPhase 3
Safety follow-up for hormone-positive, HER2-negative breast cancer
This trial studies the safety of continuing endocrine therapy with ovarian suppression (for women) after you finish the earlier OVELIA study. It may help doctors confirm that the treatment remains safe for longer-term use.
Seattle, WashingtonAges 18–51 - NCT06380751RecruitingPhase 3
New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
Tacoma, WashingtonAges 18 years+ - NCT05827081RecruitingPhase 3
Ribociclib plus endocrine therapy for early breast cancer
This trial studies whether adding ribociclib to standard hormone (endocrine) therapy lowers the risk of breast cancer coming back in early-stage, hormone-receptor–positive cancer. It mainly looks at safety and how well the treatment controls cancer after surgery and (sometimes) prior hormone treatment.
Kennewick, WashingtonAges 18–100 - NCT07078604RecruitingPhase 2
Vaccine with chemotherapy for advanced triple-negative breast cancer
This trial tests a cancer vaccine called STEMVAC combined with chemotherapy in people with a type of breast cancer that has spread and does not have certain markers. The goal is to see if adding the vaccine helps the chemotherapy work better.
Seattle, WashingtonAges 18 years+ - NCT06324357RecruitingPhase 1/Phase 2
Zongertinib for HER2-positive cancers that have spread
This trial tests a new pill called zongertinib, alone or with other drugs, for people with HER2-positive cancers (like breast, stomach, or colorectal cancer) that have spread and are no longer responding to standard treatments. The goal is to find the best dose and see if it can help shrink tumors or slow the disease.
Seattle, WashingtonAges 18 years+ - NCT07062965RecruitingPhase 3
PF-07248144 with fulvestrant for HR+ HER2- advanced breast cancer
This trial tests a new study medicine (PF-07248144) combined with fulvestrant in people with a certain type of advanced breast cancer (HR-positive, HER2-negative) that has worsened after previous treatments. It may be an option if you've already tried a CDK4/6 inhibitor and endocrine therapy.
Seattle, WashingtonAges 18 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
Seattle, WashingtonAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Vancouver, WashingtonAges 50–70 - NCT06172478RecruitingPhase 2
HER3-DXd for advanced solid tumors after prior treatment
This trial tests a new targeted drug called HER3-DXd for people with several types of advanced solid tumors that have stopped responding to standard treatments. The drug is an antibody-drug conjugate, designed to deliver chemotherapy directly to cancer cells that have a protein called HER3 on their surface.
Seattle, WashingtonAges 18 years+ - NCT05696626RecruitingPhase 3
Test a new pill plus abemaciclib versus standard therapy
This Phase 3 study compares lasofoxifene plus abemaciclib versus fulvestrant plus abemaciclib for ER-positive, HER2-negative breast cancer that has an ESR1 mutation. It looks for better tumor control in people whose cancer has progressed on hormone therapy (an aromatase inhibitor) and who meet specific safety and testing requirements.
Seattle, WashingtonAges 18 years+ - NCT07214532Recruiting
Guiding CDK4/6 inhibitor use by a blood test in breast cancer
This trial is for women and men with early-stage, hormone-positive, HER2-negative breast cancer. It uses a blood test (Signatera) to detect tiny amounts of cancer DNA and only starts a CDK4/6 inhibitor (ribociclib or abemaciclib) if the test shows cancer DNA is present.

What taking part in a her2 + breast cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
