Recruiting studies
- NCT05676255RecruitingPhase 2
SUPORT study for breast cancer survivors and their partners
This Phase 2 study looks at an online program for breast cancer survivors and their supportive partners who live together. The goal is to see whether the program helps survivors and partners during survivorship and adjustment after treatment.
Tucson, ArizonaAges 18 years+ - NCT04332588RecruitingPhase 1
Testing PET/MRI monitoring for HER2-positive breast cancer before surgery
This early-phase study looks at how well PET/MRI scans can monitor treatment response in people with HER2-positive breast cancer before surgery. You may be asked to undergo specific scans during “neoadjuvant” therapy (treatment given before the main operation).
Birmingham, AlabamaAges 18 years+ - NCT04480203Recruiting
Digital coping tools after new breast cancer diagnosis
This trial tests two online programs designed to help people cope after being diagnosed with breast cancer. It may help you manage stress and emotions during treatment or recovery.
OsloAges 20–69 - NCT06846437RecruitingPhase 3
New drug JSKN003 vs. Kadcyla for HER2-positive advanced breast cancer
This trial compares a new targeted therapy (JSKN003) against Kadcyla (T-DM1) for people with HER2-positive breast cancer that has advanced or spread. Both drugs work by attaching a chemotherapy directly to HER2-positive cancer cells, and the study aims to see if the new drug works better or has fewer side effects.
ShanghaiAges 18 years+ - NCT05861830RecruitingPhase 3
Dalpiciclib plus hormone therapy after CDK4/6 treatment
This trial tests dalpiciclib together with hormone (endocrine) therapy in people with HR-positive, HER2-negative advanced breast cancer whose cancer has already responded poorly to a prior CDK4/6 inhibitor. It aims to see if this combination can better control the cancer after that earlier treatment has failed.
Beijing, Beijing MunicipalityAges 18–80 - NCT06711068Recruiting
Chemotherapy plus targeted therapy for HER2+ early breast cancer
This trial tests whether adding targeted therapy to chemotherapy after surgery can help prevent HER2-positive early breast cancer from coming back. It is for patients whose cancer has not spread to lymph nodes and who have certain tumor sizes and features.
Beijing, Beijing MunicipalityAges Any age - NCT07527741Recruiting
HER2-Positive Breast Cancer Treatment Patterns Study
This study tracks how patients with HER2-positive early-stage breast cancer receive treatment and stick to their treatment plan after their care moves to local hospitals. The trial helps doctors understand whether patients follow through with their recommended therapy when treated closer to home.
Loznica, Bolnička 65Ages 18 years+ - NCT07739511RecruitingPhase 1/Phase 2
Oral paclitaxel for HER2-positive breast cancer before surgery
This trial tests an oral form of paclitaxel combined with standard HER2 therapy given before surgery for HER2-positive breast cancer. It aims to find the best dose and see how well it works.
Guiyang, GuizhouAges 18–70 - NCT03995082Recruiting
Survey study for newly diagnosed breast cancer patients
This study asks newly diagnosed breast cancer patients to fill out a survey about their experiences and symptoms. It may help the care team improve how they measure patient needs and experiences.
Denver, ColoradoAges Any age - 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.
Duarte, 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 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 18 years+ - NCT05263570Recruiting
Real-world treatment planning for stage II–III HR+ HER2+ breast cancer
This trial looks at how well a standard “neoadjuvant” treatment plan works in real-world patients. It is for people newly diagnosed with stage II–III HR+ breast cancer and aims to see whether treatment gives expected outcomes in everyday care.
Shenyang, LiaoningAges 18 years+ - NCT05866432RecruitingPhase 2
Dato-DXd for triple-negative breast cancer brain metastases
This trial studies Dato-DXd (an antibody-drug medicine) in people with triple-negative breast cancer that has spread to the brain. It aims to see how well it controls brain tumors when they are newly found or growing after other treatments.
Vienna, State of ViennaAges 18–100 - NCT05904964RecruitingPhase 3
Targeted drug for hormone-positive, HER2-low metastatic breast cancer
This Phase 3 trial tests disitamab vedotin (a targeted drug) in people with hormone receptor–positive, HER2-low metastatic breast cancer that can’t be cured with surgery or radiation. It aims to see whether the drug can control the cancer better than current standard care.
Guangzhou, GuangdongAges 18–70 - NCT05999149RecruitingPhase 3
Famitinib plus chemo and immunotherapy before breast cancer surgery
This trial tests whether adding a targeted therapy pill (famitinib) to standard chemo plus an immunotherapy (camrelizumab) can shrink triple negative breast cancer before surgery. It may help people with earlier-stage disease who have not had certain prior treatments.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06185569Recruiting
French study on outcomes in HR+/HER2- early breast cancer patients with Oncotype DX
This study looks at how well treatments work for people with early-stage, hormone receptor-positive, HER2-negative breast cancer when the Oncotype DX test helps guide therapy. It aims to understand real-world outcomes in French patients.

Paclitaxel side effects in breast cancer: activity and body composition
This study looks at how physical activity and body composition affect the side effects of paclitaxel, a chemotherapy drug, in women with stage II or III breast cancer. It aims to help doctors understand who might have more or fewer side effects during treatment.
Brussels, JetteAges 18 years+ - NCT06601621Recruiting
Acupuncture and self-massage for quality of life during breast cancer chemo
This trial tests whether combining electroacupuncture with self-acupressure can improve quality of life for people with early-stage breast cancer during chemotherapy. The treatment is non-invasive and aims to reduce side effects.
Xining, QinghaiAges 18–75 - NCT06928701Recruiting
Diet and exercise for early breast cancer before surgery
This trial tests whether a personalized nutrition and exercise program can improve treatment response by changing how your body and immune system react to breast cancer before surgery. It is for women newly diagnosed with early-stage breast cancer who will receive neoadjuvant therapy (treatment before surgery).

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,460 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.
