Recruiting studies
- NCT06728527Recruiting

Elacestrant for advanced ER+ HER2- breast cancer with ESR1 mutation
This trial tests elacestrant, a new hormone therapy drug, in women whose advanced or spread breast cancer has stopped responding to first-line hormone treatment. The drug is designed to work against a specific genetic change (ESR1 mutation) that can develop in these cancers.
Freiburg im BreisgauAges 18 years+ - NCT06276868RecruitingPhase 2
Darsilide plus hormone therapy and double antibody for breast cancer
This trial tests if adding a new drug (darsilide) to standard hormone therapy and two antibodies (trastuzumab and pertuzumab) before surgery can improve outcomes for women with HR-positive, HER2-positive breast cancer that hasn't spread.
Henan, HenanAges 18–70 - NCT06723899Recruiting
Work rehabilitation for women with breast cancer
This study tests a six-week online program to help women with breast cancer return to work after completing their cancer treatments (except hormone therapy). The program focuses on rebuilding work skills and confidence.
GalwayAges 18–70 - NCT06738459Recruiting
Matching lymph node tests in breast cancer
This study looks back at past MRI scans and lymph node biopsies or surgeries in people with breast cancer to better understand how cancer spreads to the lymph nodes. If you had these tests as part of your care, your data might help improve future treatment decisions.
VillachAges 18 years+ - NCT05673304Recruiting
Boost treatment before surgery for luminal B breast cancer
This trial tests a “boost” treatment given before surgery along with standard chemotherapy for luminal B–type breast cancer. It may help improve outcomes by strengthening treatment before the tumor is removed.
BolognaAges 18 years+ - NCT07555210Recruiting
Bone Density Changes During Cancer Immunotherapy
This study tracks how a type of cancer treatment called anti-PD-1 immunotherapy affects bone strength over time. Researchers want to understand whether this treatment causes bone density loss and help develop ways to protect bones during cancer care.
Nashville, TennesseeAges 18 years+ - NCT07557225Recruiting
New PET Scan for Detecting Multiple Cancer Types
This study tests a new type of PET scan (a specialized imaging test) that may better detect certain cancers by looking for a specific marker found on many tumor types. The scan uses a new tracer called 18F-T2 to help doctors see cancer more clearly.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06730815Recruiting
Body image and exercise in women with breast cancer
This study looks at how physical activity affects body image in women with breast cancer. You may join if you have been diagnosed with breast cancer and do not have other health issues that prevent exercise.
Pécs, BaranyaAges 18–80 - NCT07545122RecruitingPhase 1
Testing CT-202 for Triple Negative Breast, Colorectal, and Bladder Cancers
This early-stage trial tests a new antibody drug called CT-202 in patients whose cancer has come back after standard treatments. The drug is designed to target cancer cells that have a specific protein called Nectin-4, and may help the immune system fight the cancer.
Wahroonga, New South WalesAges 18 years+ - NCT07544056RecruitingPhase 2/Phase 3
BEBT-209 Plus Chemotherapy for Triple-Negative Breast Cancer
This study tests a new drug called BEBT-209 combined with chemotherapy (carboplatin and gemcitabine) in women with advanced triple-negative breast cancer that has spread or cannot be surgically removed. The goal is to see if this combination can slow or stop cancer growth better than standard treatments.
Guangzhou, GuangdongAges 18–75 - NCT07543536RecruitingPhase 3
Megestrol Acetate for Fatigue in HER2+ Breast Cancer
This study tests whether a medication called megestrol acetate can help reduce severe tiredness and fatigue in people with advanced breast cancer who are receiving a targeted therapy called T-DXd (trastuzumab deruxtecan). Fatigue is a common side effect that can really impact quality of life.
Guangzhou, GuangdongAges 18–75 - NCT07540533RecruitingPhase 2
Toripalimab Plus Chemotherapy for Advanced HER2-Negative Breast Cancer
This trial tests a combination of toripalimab (an immunotherapy drug) with chemotherapy to treat advanced breast cancer that is HER2-negative. The goal is to see if this combination can help slow or stop cancer growth in patients who have already tried other treatments.
Zhengzhou, HenanAges 18 years+ - NCT07541079RecruitingPhase 3
Testing a New Breast Cancer Drug for Women Who Can't Tolerate Current Therapy
This study tests giredestrant, a new hormone-blocking medication, in postmenopausal women with early-stage ER+ breast cancer who have experienced intolerable side effects from their current aromatase inhibitor therapy. The trial will measure how well you tolerate this new drug and how it affects your quality of life.
Fountain Valley, CaliforniaAges 18 years+ - NCT07542496Recruiting
Real-world study of breast cancer treatment with pertuzumab biosimilar
This study observes how a biosimilar version of pertuzumab (a targeted breast cancer drug) works in real-world patients. Researchers will track outcomes in patients receiving this drug either before surgery or as a first treatment for advanced breast cancer.
AlgiersAges 19 years+ - NCT07531836Recruiting
Prehabilitation for older adults having breast cancer surgery
This trial tests a program of exercise and support before breast cancer surgery to help older patients recover better. It aims to improve strength and overall health so you can get back to your daily life sooner after the operation.
Pamplona, NavarreAges 65 years+ - NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.
ShanghaiAges 18 years+ - NCT07524322RecruitingPhase 1
RGT-490 for Advanced Cancers With PIK3CA Mutations
This study tests a new drug called RGT-490 in patients with advanced solid tumors (cancers that have spread or cannot be removed by surgery) that have a specific genetic change called a PIK3CA mutation. The drug is designed to block a protein involved in cancer cell growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06658080Recruiting
Testing drugs on fluid from breast cancer
This trial uses fluid from the chest or belly of breast cancer patients to grow tiny tumor models in the lab. These models help doctors find which drugs might work best for each patient.
Hangzhou, ZhejiangAges 18–70 - NCT07510802RecruitingPhase 1/Phase 2
CAR-NK cells for advanced HER2+ or triple-negative breast cancer
This trial tests a new type of immune cell therapy (CAR-NK cells) that targets specific proteins on breast cancer cells. It's for people with advanced HER2-positive or triple-negative breast cancer who have tried other treatments or can't take them.

Nipple-sparing mastectomy through one armpit incision
This trial tests a less invasive surgery for early-stage breast cancer that removes breast tissue through a single small cut in the armpit while keeping the nipple. It may be an option for women with small to medium breasts who are candidates for immediate breast reconstruction.
Candiolo, TurinAges 18 years+ - NCT07510698Recruiting
Same-day awake mastectomy with immediate breast reconstruction
This study tests whether people can have a mastectomy while awake (using numbing medicine instead of general anesthesia) and go home the same day with immediate breast reconstruction. It may be an option if you're healthy enough and have support at home.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 recruiting 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 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 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.
