Recruiting studies
- NCT06638294Recruiting
Study for breast cancer spread to brain lining
This study is for people with breast cancer that has spread to the lining of the brain or spinal cord (called leptomeningeal metastasis). Researchers want to understand how to treat this condition and offer care to those who qualify.
Washington D.C., District of ColumbiaAges 4 months+ - NCT06638931RecruitingPhase 2
Nivolumab for rare solid tumors with high PD-L1
This trial is testing a drug called Nivolumab (an immunotherapy) for people with rare solid tumors that have high levels of PD-L1. It might be an option if you have tried other treatments and they stopped working or caused too many side effects.
Fortaleza, CearáAges 18 years+ - NCT06639178Recruiting
Cream to prevent hand-foot syndrome from capecitabine in breast cancer
This trial tests whether a special cream containing N-acetylcysteine and urea can prevent the painful hand-foot syndrome often caused by the chemotherapy drug capecitabine. If you have breast cancer and are about to start capecitabine, this study may help reduce side effects.
Aviano, PordenoneAges 18 years+ - NCT06641544RecruitingPhase 4
Testing different drug combos for HER2-positive breast cancer
This trial tests different combinations of the drug Inetetamab as a first treatment for breast cancer that has spread and is HER2-positive. It aims to find which combo works best and is safe for newly diagnosed metastatic patients.
Shanwei, GuangdongAges 18–70 - NCT06642441Recruiting
Vitamin D for reducing chemotherapy side effects in breast cancer
This trial tests whether taking vitamin D supplements can reduce side effects from chemotherapy in people with breast cancer. It is for patients with low vitamin D levels who are about to start their first chemotherapy treatment.
Xining, QinghaiAges 18–80 - NCT06642428Recruiting
Vitamin D for breast cancer treatment before surgery
This trial tests whether taking vitamin D pills during chemotherapy or targeted therapy (before breast cancer surgery) can improve how well the treatment works and reduce side effects. It is for women with low vitamin D levels.
Xining, QinghaiAges 18–80 - NCT06642545RecruitingPhase 2
New targeted drug combo for HER2-low breast cancer
This trial tests a new combination of targeted drugs (Disitamab Vedotin and RC148) against a standard chemotherapy (Abraxane) with or without an immunotherapy drug (Toripalimab) for advanced breast cancer that is HER2-low and hormone receptor-negative. The goal is to see if the new combination works better at shrinking tumors and slowing cancer growth.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06642948Recruiting
AI system for exercise rehab in breast cancer survivors
This study tests a new AI-based skeleton recognition system to guide rehabilitation exercises for breast cancer survivors. It may help reduce pain and improve mobility for those taking aromatase inhibitors.
ShanghaiAges Any age - NCT06643767Recruiting
Testing a new breast exam device during mammogram
This study tests a new device called Bexa that examines the breast to see if it works well along with a standard mammogram. It may help find breast concerns more easily.
Abilene, TexasAges 30–75 - NCT06648148Recruiting
Molecular markers for radiation response in breast cancer
This trial looks for biomarkers (biological signs) in breast tissue that might predict how well breast cancer responds to radiation therapy. It is for patients with ductal carcinoma in situ (DCIS) who are scheduled to receive radiation after surgery.
LjubljanaAges 18–75 - NCT06649565Recruiting
AI model to predict breast cancer treatment response
This trial uses an artificial intelligence model to predict how well breast cancer responds to neoadjuvant therapy (treatment before surgery). It aims to improve treatment planning by analyzing MRI scans taken before and after therapy.
Beijing, Beijing MunicipalityAges 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 - NCT06660628Recruiting
Radiation therapy with or without breath-hold for left breast cancer
This study compares two types of radiation therapy for left breast cancer: one using a breath-holding technique to protect the heart, and another without it. The goal is to see which is safer and more effective for women who have had surgery.
Beijing, Beijing MunicipalityAges 18–70 - NCT06663228Recruiting
Faster breast biopsy analysis with mass spectrometry and AI
This trial uses a small mass spectrometer and artificial intelligence to quickly analyze breast tissue during a stereotactic biopsy. It aims to speed up detection and improve early diagnosis.
TaipeiAges 20–99 - NCT06665178RecruitingPhase 2
Testing SG after T-DXd in ER+/HER2-low metastatic breast cancer
This trial tests whether a different chemotherapy drug, called sacituzumab govitecan (SG), can help people with ER+/HER2-low metastatic breast cancer who have already been treated with trastuzumab deruxtecan (T-DXd). It also looks at genetic markers in your tumor to predict who might benefit from SG.
Vancouver, British ColumbiaAges 18 years+ - NCT06672120Recruiting
Exercise for triple-negative breast cancer patients
This trial tests whether a structured exercise program can help women with newly diagnosed triple-negative breast cancer who are getting a specific combination of immunotherapy and chemotherapy. The goal is to see if staying active during treatment improves outcomes and well-being.
Munich, BavariaAges 18–65 - NCT06672302Recruiting
Blood test to find high breast cancer risk
This study uses a blood test to help identify women who are at high risk for breast cancer. It is for Korean women aged 40 or older who have a suspicious breast finding and need a biopsy.
SeoulAges 40 years+ - NCT06672497Recruiting
Testing a light sensor for muscle health in breast and gynecological cancer patients
This study uses a safe, non-invasive light sensor (near-infrared spectroscopy) to measure how well your muscles use oxygen. Researchers want to learn if this tool can help monitor muscle health in people with breast or gynecological cancer that has not spread to other parts of the body.
Greenville, South CarolinaAges 20 years+ - NCT06676761Recruiting
Study of a new minimal scar mastectomy
This trial is testing a new surgical technique that leaves a smaller scar during mastectomy for breast cancer. It may be a good option if you want to keep the scar as small as possible.
SingaporeAges Any age - NCT06677879RecruitingPhase 2
Proton vs photon radiation for left-sided breast cancer
This study is comparing two types of radiation therapy—proton therapy and standard photon therapy—for people with left-sided breast cancer who need radiation after surgery. The goal is to find out which method best protects the heart while effectively treating the cancer.
ShanghaiAges 18–80 - NCT06678048RecruitingPhase 2
Arsenous acid for hard-to-treat triple-negative breast cancer
This trial tests a medicine called arsenous acid for people with triple-negative breast cancer that has not responded to at least two prior treatments. If you join, you will get arsenous acid plus one of four chemotherapy drugs to see if the combination can shrink tumors.
Guangzhou, GuangdongAges 18–75 - NCT06678776Recruiting
Study of breast fascia during mastectomy or reduction
This trial studies the natural structure of connective tissue (fascia) in the breast during surgery. It may help doctors better understand how to preserve important structures during mastectomy or breast reduction.

Combination therapy for advanced breast cancer
This trial tests new drug combinations for advanced or metastatic breast cancer. It aims to see if adding HRS-2189, HRS-6209, or HRS-1358 to standard treatments works better. Participants must have tried certain hormone therapies or chemotherapies before.
