- NCT07391774RecruitingPhase 3
Hormone therapy with or without chemo for early breast cancer
This trial tests whether skipping chemotherapy and using only hormone therapy with a drug called ribociclib works as well as chemotherapy followed by hormone therapy with ribociclib for certain early breast cancers that have a low risk of coming back.
Palo Alto, CaliforniaAges 18 years+ - NCT06638307RecruitingPhase 1
Study of new drug MEN2312 for advanced breast cancer with specific genetic changes
This trial tests a new drug, MEN2312, for people with advanced breast cancer that has specific genetic changes in PIK3CA, AKT1, or PTEN. It's for those who have already tried certain hormone therapies and a CDK4/6 inhibitor combination, and the cancer has continued to grow.
Palo Alto, CaliforniaAges 18 years+ - NCT04888975Recruiting
Device study for one-arm swelling after lymph surgery
This study tests a medical device (Dayspring Technology) to reduce swelling in the arm caused by breast cancer treatment and lymph surgery. You may be eligible if you have one-sided arm swelling after lymphatic surgery and meet safety checks for the device.

Palo Alto, CaliforniaAges 18–100 - NCT07647328RecruitingPhase 3
Camizestrant and ribociclib for advanced hormone-receptor-positive breast cancer
This trial tests a combination of two drugs (camizestrant and ribociclib) for advanced breast cancer that is hormone-receptor-positive and HER2-negative. The study aims to see if this combination helps patients whose cancer cannot be surgically removed or treated with radiation alone.
Palo Alto, CaliforniaAges 18–130 - NCT07405801RecruitingPhase 2
Inavolisib plus ribociclib plus fulvestrant for advanced breast cancer
This trial tests a combination of three drugs (inavolisib, ribociclib, and fulvestrant) compared to a placebo plus two of the drugs (ribociclib and fulvestrant) for people with advanced hormone receptor-positive breast cancer who have not had prior treatment for advanced disease. The goal is to see if adding inavolisib improves outcomes.
Palo Alto, CaliforniaAges 18 years+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Palo Alto, CaliforniaAges Any age - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Stanford, CaliforniaAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 3
Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Stanford, CaliforniaAges 18 years+ - NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
Stanford, CaliforniaAges 18 years+ - NCT07046923RecruitingPhase 1
A study of LY4175408 for advanced cancer
This trial tests a new targeted drug (LY4175408) for people with certain advanced solid tumors (lung, endometrial, or triple negative breast cancer) who have already tried standard treatments. The goal is to see if the drug is safe and effective.
Stanford, CaliforniaAges 18 years+ - NCT07114601RecruitingPhase 1
Study of LY4257496 for people with GRPR-positive solid tumors
This trial tests a new drug, LY4257496, in people with certain types of cancer that have a protein called GRPR on their cells. The study aims to see if the drug can help shrink tumors or slow the cancer's growth.
Stanford, CaliforniaAges 18 years+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Stanford, CaliforniaAges Any age - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Stanford, CaliforniaAges 18–75 - NCT07701941RecruitingPhase 1/Phase 2
Combination treatment for advanced breast cancer
This trial tests two targeted drugs together for people with advanced breast cancer that is hormone receptor positive and has low levels of a protein called HER2. The goal is to see if this combination helps shrink tumors or slow the cancer's growth.
Stanford, CaliforniaAges 18 years+ - NCT04768426RecruitingPhase 2
Watching DNA in blood while taking capecitabine after breast cancer
This trial checks how a blood test that looks for cancer DNA (ctDNA) changes during and after you take capecitabine after early triple-negative breast cancer. It aims to see whether these blood test results can help monitor the chance of the cancer coming back.
Stanford, CaliforniaAges 18 years+ - NCT01035112Recruiting
MRI check for suspicious breast changes
This study uses a breast MRI scan to look at suspicious areas in the breast. It may help doctors better tell which breast changes need closer follow-up like a biopsy.
Stanford, CaliforniaAges 21 years+ - NCT03424005RecruitingPhase 1/Phase 2
Testing new drug combinations for advanced breast cancer
This study tests how well and how safely different combinations of cancer drugs work for people with metastatic or inoperable locally advanced breast cancer. It may help by finding a better treatment option and collecting information to guide future care.
Stanford, CaliforniaAges 18 years+ - NCT05978141Recruiting
T-cell lymphoma registry study
This study creates a registry for people with certain T-cell or NK-cell lymphomas. It collects health information and tumor samples to learn more about these diseases and improve future treatments.
Stanford, CaliforniaAges Any age - NCT01034033Recruiting
Blood and tumor genetic study for BRCA and related risks
This study collects blood (and possibly tumor tissue) to learn how certain inherited gene changes relate to breast and ovarian cancer risk. It may help researchers understand which people are most likely to develop these cancers and how tumors differ in high-risk patients.
Stanford, CaliforniaAges 18 years+ - NCT05059444Recruiting
Blood test to catch cancer early after treatment
This study looks for signs of cancer left in the body after treatment using a simple blood test (called a liquid biopsy). It aims to see if the test can catch cancer that might come back earlier than regular scans.
Redwood City, CaliforniaAges 18 years+ - NCT06995898Recruiting
Blood test study for early cancer detection
This study is testing a new blood test that may help find cancer early. You will give blood samples over a year, and researchers will check them for signs of cancer.
Pleasanton, CaliforniaAges 45–75 - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.

What taking part in a 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.
