Radiation, chemo, and immunotherapy for HR+ breast cancer
This trial tests if giving radiation first, then chemo with an immunotherapy drug called Toripalimab, can help treat a certain type of breast cancer that has not spread to other organs. It is for people with hormone receptor positive, HER2 negative breast cancer that is growing fast.
Hangzhou, ZhejiangAges 18–75 - NCT05536128RecruitingPhase 2
Fulvestrant plus DNA damage drugs after CDK4/6 treatment failure
This Phase 2 trial studies whether combining fulvestrant with medicines that block DNA repair can help treat HR+/HER2- metastatic or inoperable breast cancer that has progressed after endocrine therapy plus a CDK4/6 inhibitor. It also aims to check the safety of this combination and see if it can control the cancer for longer.
SeoulAges 19 years+ - NCT06700369Recruiting
Lowering chemo with targeted therapy for HER2+ breast cancer
This study looks at whether using targeted therapy can reduce the amount of chemotherapy needed before surgery for HER2-positive breast cancer. It aims to find a safer, equally effective treatment plan.
Beijing, Beijing MunicipalityAges Any age - NCT06642142Recruiting
When numbness starts after a spine block for breast surgery
This study is testing how quickly numbness starts after a specific type of pain block (erector spinae plane block) given before breast surgery. It may help people who are having breast surgery and are healthy enough to receive this block.
Latina, ItalyAges 18 years+ - NCT06007027Recruiting
Vaginal laser therapy for breast cancer survivors with menopause symptoms
This trial tests whether a vaginal laser treatment can help breast cancer survivors who have menopause-like symptoms such as vaginal dryness or pain during sex. It is designed for women currently on hormone-blocking therapy.
RandersAges 18–100 - NCT06481956Enrolling by invitationPhase 2
T-DM1 plus a CDK4/6 inhibitor (ribociclib) for HER2-positive breast cancer
This clinical trial tests a combination of two targeted therapies for people with HER2-positive breast cancer that has spread or come back. The goal is to see if adding ribociclib to T-DM1 is safe and effective after other treatments have been used.
Hangzhou, ZhejiangAges 18–75 - NCT06301438Recruiting
Dalpiciclib for HR+/HER2- advanced breast cancer
This trial tests a drug called Dalpiciclib for people with a certain type of advanced breast cancer (HR-positive, HER2-negative). It aims to see if it can help stop the cancer from growing.
ShanghaiAges 18 years+ - NCT07096869RecruitingPhase 1
Breast cancer trial comparing two forms of paclitaxel
This study checks if a generic version of paclitaxel protein-bound particles works the same as the brand-name drug in people with breast cancer. It's for patients whose cancer has spread or returned, and who might benefit from this medicine alone.
Changchun, JilinAges 18–75 - NCT07180693Recruiting
Breast cancer that returns after CDK4/6 inhibitor treatment
This study looks at patients whose breast cancer returns after starting a CDK4/6 inhibitor (like abemaciclib or ribociclib) along with hormone therapy. The goal is to understand why the cancer comes back and find better ways to treat it.
Bergamo, ItalyAges 18 years+ - NCT06469606Recruiting
Mammogram texture study for women having mastectomy
This study looks at mammogram images of women who are scheduled to have one or both breasts removed (mastectomy). Researchers want to learn about patterns in breast tissue to improve future breast cancer screening.
TampereAges 18 years+ - NCT06552091Recruiting
Digital self-hypnosis for hot flashes from hormone therapy
This trial tests a guided digital self-hypnosis program to help reduce hot flashes caused by hormone therapy for breast cancer. It aims to see if it can make hot flashes less frequent and bothersome.
Vandœuvre-lès-NancyAges 18 years+ - NCT07426822RecruitingPhase 2
Preventing Rash and Diarrhea with Capivasertib for Breast Cancer
This trial tests whether giving a combination of the drugs capivasertib and fulvestrant, along with medicines to prevent rash and diarrhea, can help treat hormone receptor-positive breast cancer that has a PIK3CA, AKT1, or PTEN change. It's for people whose cancer has spread or is locally advanced and can't be removed with surgery.

Testing a new drug for advanced cancers with gene changes
This study tests a new oral drug, DSB2455, for people with advanced breast, prostate, ovarian, or pancreatic cancers that have certain gene changes. It aims to see if the drug is safe and whether it helps shrink or control the cancer.
New Haven, ConnecticutAges 18 years+ - NCT07579650Recruiting
Nerve Block for Pain Relief After Breast Surgery
This trial tests a special numbing technique (called a serratus posterior superior intercostal plane block) to help reduce pain after mastectomy surgery. The goal is to see if this nerve block reduces the need for pain medications after your procedure.

Track metabolic health habits during breast cancer treatment
This study follows how “metabolic health” patterns (like eating timing and daily activity) change over time during breast cancer care. It may help researchers learn which habit patterns are linked to better outcomes and comfort during chemotherapy.
Edmonton, AlbertaAges 18 years+ - NCT07705438Recruiting
PET scan to predict if immunotherapy works in TNBC
This trial tests a new type of PET scan (Granzyme B-PET) to see if it can predict how well immunotherapy will work for people with triple-negative breast cancer that has spread. If it works, doctors might be able to tell sooner whether treatment is helping.
ShanghaiAges 18 years+ - NCT02992574Recruiting
Radiation after mastectomy for certain node-negative breast cancers
This trial studies whether giving radiotherapy after a mastectomy helps prevent breast cancer coming back in women whose lymph nodes are not involved (or only very tiny spread). It may help reduce recurrence risk, especially for patients with higher-risk features despite node-negative early cancer.
Chandigarh, ChandigarhAges 18–80 - NCT03053193Recruiting
Testing gene activity to guide breast cancer treatment
This study links breast tumor test results from MammaPrint and optional BluePrint (and full genetic data) with real-world clinical information to understand which new gene activity patterns matter. It may help future patients by improving how doctors use these tests to guide care.
Birmingham, AlabamaAges 18 years+ - NCT03417622RecruitingPhase 3
Wide vs narrow breast surgery margins after lumpectomy
This study compares two ways of cutting the edge (margin) of tissue during lumpectomy after breast cancer treatment. It may help reduce the chance of the cancer coming back locally by testing whether a wider margin is better than a narrow one.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,477 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.
