Shanghai, Shanghai MunicipalityAges 18–75 - NCT06044623RecruitingPhase 3
Tailoring cancer pill dosing for older adults with breast cancer
This trial is testing whether adjusting the dose of a targeted therapy (CDK 4/6 inhibitor) based on a geriatric assessment can be as effective and safer for people aged 70 and older with advanced hormone receptor-positive, HER2-negative breast cancer. It aims to find the best dose to balance benefits and side effects.
HelsinkiAges 70 years+ - NCT06055881Recruiting
Using radiation to delay changing treatment for breast cancer
This trial tests whether giving radiation to a few growing spots (1-3) can let you stay on your current drug longer, instead of switching to a new one right away. It's for people with metastatic breast cancer whose disease has been stable for months but now shows limited progression.
Scottsdale, ArizonaAges 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+ - NCT06079983RecruitingPhase 3
JSKN003 vs. doctor's choice for HER2-low breast cancer
This trial compares a new experimental drug, JSKN003, to standard treatments chosen by your doctor for advanced breast cancer that tests as HER2-low (IHC 1+ or 2+ but not amplified). It's for people whose cancer has spread or can't be removed and who have already had one or two lines of chemotherapy.
Guangzhou, GuangdongAges 18 years+ - NCT06081959RecruitingPhase 3
Study of SKB264 for advanced HR+/HER2- breast cancer
This trial tests a new drug called SKB264 for people with a common type of breast cancer (HR+/HER2-) that has spread or come back and has not responded to at least one round of chemotherapy. It aims to see if this treatment can help shrink tumors or slow the disease.
Beijing, Beijing MunicipalityAges 18–75 - 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+ - NCT06104085Recruiting
Imaging test for Trop2 in triple-negative breast cancer
This trial tests a new imaging agent (99mTc-MY6349) to see if it can detect Trop2, a protein found on some breast cancer cells. It may help doctors better see and understand triple-negative breast cancer that has spread.
Beijing, Beijing MunicipalityAges 18–80 - NCT06105684RecruitingPhase 2
Low-dose capecitabine for advanced breast cancer
This trial tests a lower dose of the chemotherapy drug capecitabine in people with advanced breast cancer that is HER2 negative. It aims to see if this gentler dose works well, especially for older or frailer patients who may have more difficulty with standard treatment.
Birmingham, AlabamaAges 60 years+ - NCT06110793RecruitingPhase 1/Phase 2
Study of lenvatinib, pembrolizumab, and fulvestrant for advanced breast cancer
This trial tests a combination of three drugs (lenvatinib, pembrolizumab, and fulvestrant) for people with a certain type of advanced breast cancer that has stopped responding to previous hormone therapy. The goal is to see if this new combination can help shrink or control the cancer.
Basking Ridge, New JerseyAges 18 years+ - NCT06121700RecruitingPhase 2
Chemoimmunotherapy and radiation before surgery for limited spread stomach cancer
This trial tests combining chemotherapy, immunotherapy, and radiation before surgery for stomach or gastroesophageal junction cancer that has spread to a limited number of sites. The goal is to see if this approach can improve outcomes by shrinking tumors before they are removed.
ShanghaiAges 18–75 - NCT06126406RecruitingPhase 1
CEA-targeting CAR-T cell therapy for advanced solid tumors
This trial tests a new immune cell therapy (CAR-T) designed to attack cancer cells that make a protein called CEA. It may be an option for people with advanced colorectal, esophageal, gastric, or pancreatic cancer who have already tried at least two standard treatments.
Wuhu, AnhuiAges 18 years+ - NCT06127797Recruiting
MRI surveillance study for breast cancer survivors with dense breasts
This study is testing whether adding an MRI to your regular mammogram can help find any new breast cancers earlier. It is for women who have had breast cancer before and still have dense breast tissue, making mammograms harder to read.
Houston, TexasAges 18 years+ - NCT06129747RecruitingPhase 2
Repeat Lumpectomy and Daily Partial Breast Radiation for Cancer Return
This trial studies a second breast-conserving surgery followed by daily radiation to just the tumor area for people whose breast cancer has returned in the same breast. It aims to see if this approach is safe and effective, potentially avoiding a mastectomy.
Cleveland, OhioAges 19 years+ - 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.
Tokyo, TokyoAges 18–80 - NCT06143553RecruitingPhase 3
Paclitaxel micelles for metastatic breast cancer
This trial tests a new form of paclitaxel (a chemotherapy drug) for metastatic breast cancer that is HER2-negative. It may be an option if your cancer has returned or not improved after 2 to 4 previous treatments.

Common questions
- Are there clinical trials for metastatic breast cancer?
- Yes. Clin2 currently lists 1,332 recruiting metastatic breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a metastatic breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a metastatic breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
