Recruiting studies
- NCT06135714RecruitingPhase 3
Targeting limited breast cancer spread with focused therapy
This trial tests whether treating just the few spots where breast cancer has spread (called oligometastases) with radiation or surgery can help control the disease. It is for people whose cancer has spread to 3 or fewer places, each small in size, and who are healthy enough for local treatments.
Bunkyō-Ku, TokyoAges 18 years+ - NCT06120283RecruitingPhase 1
Study of BGB-43395 alone or with other drugs for advanced solid tumors
This study tests a new drug called BGB-43395 alone or with other treatments for advanced solid tumors, especially breast cancer. The goal is to find the best dose and see how well it works. It may be an option if your cancer has not responded to other treatments.
Denver, ColoradoAges 18 years+ - NCT06106477Recruiting
Intermittent fasting for women with early breast cancer

Participation may involve following a fasting or exercise plan for a period of time.
Phoenix, ArizonaAges 18 years+ - NCT06092892RecruitingPhase 2
Upfront targeted lymph node removal for early breast cancer
This trial is for women age 45 and older with early ER-positive breast cancer that has spread to the lymph nodes under the arm. It tests a surgery approach where the main tumor and only a few key lymph nodes (rather than many) are removed.
Los Angeles, CaliforniaAges 45 years+ - NCT06085742RecruitingPhase 2
CMC chemotherapy for early stage breast cancer
This trial tests a chemotherapy combination (CMC) for people with early-stage, hormone receptor-positive, HER2-negative breast cancer who have a high risk of recurrence. It aims to understand if this oral regimen is effective and tolerable.
Chicago, IllinoisAges 18 years+ - NCT06099769RecruitingPhase 2
Testing enzalutamide with or without mifepristone for AR-positive breast cancer
This trial tests if adding the drug mifepristone to the standard antiandrogen enzalutamide works better than enzalutamide alone or chemotherapy for people with a specific type of breast cancer that has androgen receptors. It aims to find a new targeted treatment option for triple-negative or ER-low breast cancer.
Birmingham, AlabamaAges 18 years+ - NCT05929768RecruitingPhase 3
Shorter chemo plus immunotherapy without anthracyclines for early TNBC
This Phase 3 trial tests whether a shorter course of chemotherapy plus immunotherapy can work as well as standard treatment for early-stage triple-negative breast cancer. It avoids anthracycline drugs and may help reduce exposure to those medicines if the shorter plan is effective and safe.
Birmingham, AlabamaAges 18 years+ - NCT06058377RecruitingPhase 3
Adding immunotherapy to chemo for stage II-III breast cancer
This trial tests whether adding the immunotherapy drug durvalumab to standard chemotherapy works better than chemo alone for people with hormone receptor positive, HER2 negative breast cancer that is stage II or III and has a high-risk genetic score (MammaPrint High Risk 2).
Birmingham, AlabamaAges 18 years+ - NCT03694756Recruiting
Testing special MRI to see tiny breast cancer structures
This study is testing whether a special MRI scan can help show tiny features inside breast tumors (TMEM). It’s mainly a “feasibility” study, meaning the team is checking if the scan can be done safely and clearly in different types of operable breast cancer.
The Bronx, New YorkAges 18 years+ - NCT06064812RecruitingPhase 1/Phase 2
Testing a new drug for advanced ER-positive breast cancer
This trial tests an experimental oral drug (FWD1802) for women with a specific type of advanced breast cancer (ER-positive, HER2-negative) that has stopped responding to hormone therapy. It looks at whether the drug can slow or stop cancer growth, especially if you have an ESR1 mutation.
Hefei, AnhuiAges 18 years+ - NCT06072612RecruitingPhase 3
Bria-IMT plus CPI vs standard care for advanced breast cancer
This trial tests a new combination of two immunotherapy drugs (Bria-IMT and a checkpoint inhibitor) against your doctor's choice of standard treatments. It is for people with advanced breast cancer that has spread and who have already tried several prior therapies.
Phoenix, ArizonaAges 18 years+ - NCT04553770RecruitingPhase 2
Trastuzumab deruxtecan with or without anastrozole for early breast cancer
This Phase 2 study tests whether trastuzumab deruxtecan alone or combined with anastrozole can control early-stage breast cancer that is HER2-low and hormone-receptor positive. It aims to improve outcomes after initial surgical treatment by targeting cancer cells that may have low levels of HER2.
Fullerton, CaliforniaAges 18 years+ - NCT06062498RecruitingPhase 2
Elacestrant alone or with a CDK4/6 inhibitor for advanced breast cancer
This trial compares a new hormone therapy (elacestrant) to the same therapy combined with a CDK4/6 inhibitor (palbociclib, abemaciclib, or ribociclib) for people with a specific type of advanced breast cancer (ER-positive, HER2-negative) that has a mutation in the ESR1 gene. It aims to see if the combination works better than the single drug.
Chicago, IllinoisAges 18 years+ - NCT06042569RecruitingPhase 2
Lower-dose chemo for older women with HER2-negative breast cancer
This trial tests whether a lower dose of two chemotherapy drugs (docetaxel and cyclophosphamide) works well for women 65 and older with early-stage HER2-negative breast cancer. The goal is to maintain effectiveness while reducing side effects in this group.
Duarte, CaliforniaAges 65 years+ - NCT05910398RecruitingPhase 3
Extending anti-HER2 treatment after breast cancer surgery
This Phase 3 trial tests whether continuing or pausing the anti-HER2 medicine pyrotinib after surgery can lower the chance that invasive HER2-positive breast cancer comes back. It may help people who have recently finished trastuzumab or T-DM1 and are well enough to take tablets.
ShanghaiAges 18 years+ - NCT06026657RecruitingPhase 1/Phase 2
NK cells with or without naxitamab for GD2-positive breast cancer
This trial tests a new treatment using immune cells called NK cells combined with chemotherapy (gemcitabine) and possibly naxitamab for people with a certain type of advanced breast cancer that has spread. It aims to see if this approach can help when standard treatments have stopped working.
Columbus, OhioAges 18 years+ - NCT06016387RecruitingPhase 2
Drug combo with radiation for HER2+ breast cancer spread to spinal lining
This trial tests a combination of three targeted drugs (tucatinib, trastuzumab, and capecitabine) along with radiation to the brain or spine for people whose HER2-positive breast cancer has spread to the lining of the brain or spinal cord. The goal is to see if this treatment is safe and effective.
Ottawa, OntarioAges 18 years+ - NCT05982093RecruitingPhase 2
Elacestrant with or without triptorelin for premenopausal breast cancer
This trial tests a new hormone-blocking pill (elacestrant) with or without a shot that temporarily stops ovaries (triptorelin) for premenopausal women with early-stage, hormone-sensitive breast cancer. It aims to find a gentler treatment option before surgery.
Badalona, BarcelonaAges 35 years+ - NCT05989347RecruitingPhase 1
