Recruiting studies
- NCT06341894RecruitingPhase 2
Dalpiciclib and hormone therapy for early breast cancer
This trial tests a new pill (dalpiciclib) combined with hormone therapy for women with early-stage, hormone receptor positive/HER2-negative breast cancer. The goal is to see if this combination can lower the chance of cancer coming back after surgery.
Nanjing, JiangsuAges 18–75 - NCT06334471Recruiting
Whole genome sequencing for breast cancer
This trial uses whole genome sequencing, a test that reads the complete set of your DNA, to study breast cancer tissue. This may help doctors learn more about the disease and find better treatments.
SeoulAges 19 years+ - NCT05800132Recruiting
AI helps review routine breast mammograms for screening
This study tests whether an artificial intelligence (AI) system can help a second reader interpret routine breast screening mammograms. It may improve how consistently images are assessed, especially when the first reader calls them normal or benign.
AubagneAges 50–74 - NCT06341621RecruitingPhase 3
Skipping chemo for ER+/HER2- breast cancer with 1–3 positive nodes
This trial tests whether skipping chemotherapy is safe for women with a specific type of early-stage breast cancer (ER-positive, HER2-negative) that has spread to 1–3 lymph nodes. Instead of chemo, you would receive a targeted pill called abemaciclib after standard hormone therapy.
ShanghaiAges 18–80 - NCT06149130RecruitingPhase 2
Testing adebrelimab, dalpiciclib, and hormone therapy for advanced breast cancer
This trial tests a combination of a new immunotherapy drug (adebrelimab) with a targeted pill (dalpiciclib) and standard hormone therapy for women with advanced hormone receptor positive, HER2 negative breast cancer. It may help patients who have not yet had certain prior treatments, aiming to slow the cancer's growth.
Wuhan, HubeiAges 18–75 - NCT02897700RecruitingPhase 1
Testing chemotherapy choices for early breast cancer after surgery
This Phase 1 study tests different chemotherapy approaches in people with breast cancer that has been surgically removed but is early stage. It aims to find a chemotherapy plan that’s safe and works well right after surgery.
Ganzhou, JiangxiAges 18 years+ - NCT06404697RecruitingPhase 2
Extra radiation to lymph nodes above collarbone for high-risk breast cancer
This trial tests giving a focused, higher dose of radiation to the lymph nodes above the collarbone after breast cancer treatment. It is for patients whose cancer did not fully disappear from those nodes after pre-surgery chemotherapy, to see if extra radiation can help prevent recurrence.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06313086RecruitingPhase 3
New drug vs. T-DM1 for HER2-positive advanced breast cancer
This trial tests a new antibody-drug conjugate (DP303c) against an existing one, T-DM1, in people with HER2-positive advanced breast cancer who have already been treated with trastuzumab and a taxane. The goal is to see if the new drug works better or has fewer side effects.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07850869Recruiting
Virus injection plus immunotherapy for advanced breast cancer
This study tests a new approach that combines a modified virus (H101) injected directly into the tumor with immunotherapy drugs that help your immune system fight cancer. It is for people with advanced breast cancer who have already tried standard treatments and could not continue chemotherapy.
Guangdong, FoshanAges 18–75 - NCT06389006RecruitingPhase 2
Combination therapy before surgery for HER2-low, hormone-positive breast cancer
This trial tests a combination of two drugs (disitamab vedotin and toripalimab) followed by chemotherapy before surgery for people with a specific type of breast cancer that is hormone receptor-positive and HER2-low. The goal is to see if this treatment can shrink the tumor and improve outcomes.
Shanghai, Fudan University Shanghai Cancer CenterAges 18 years+ - NCT05851053Recruiting
Study of heart function years after breast cancer treatment
This study checks how well your heart works long after breast cancer treatment. If you joined the earlier de BLOC-I study, you may be invited for follow-up to understand long-term heart effects.
GroningenAges Any age - NCT03815890RecruitingPhase 2
Pre-surgery nivolumab for certain types of breast cancer
This trial tests whether giving nivolumab before surgery (neoadjuvant treatment) can improve outcomes for people with certain resectable breast cancers. It focuses on tumor types linked to immune activity (like triple-negative and specific lab markers).
AmsterdamAges 18 years+ - NCT05460975Recruiting
Study of dense breast tissue seen on ultrasound
This study looks at breast cancer risk by analyzing what is seen in dense breast tissue during a screening ultrasound. It may help improve how doctors evaluate risk in people with very dense breasts.
SeoulAges 40–69 - NCT07844395Recruiting
Stress ball for pain and anxiety during breast biopsy
This study tests whether squeezing a small ball (stress ball) during a breast biopsy can help reduce pain, anxiety, and changes in heart rate and blood pressure. If you are having your first breast biopsy, you may be able to participate and help learn if this simple technique improves comfort.
KayseriAges 18 years+ - NCT07844941Recruiting
Personal exercise coach for breast cancer recovery
This trial uses an artificial intelligence app to create a personal exercise plan for you after your main breast cancer treatment. The goal is to help you recover and improve your health.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07837245Enrolling by invitation
Expanding breast cancer screening for women in Ljubljana
This study tests whether expanding the DORA breast cancer screening programme to include women aged 45-49 and 70-74 works well. If you join, you will receive regular mammograms (breast X-rays) to check for cancer early.
LjubljanaAges 45–74 - NCT07835139Recruiting
Shorter radiation schedule after breast implant reconstruction surgery
This trial compares a shorter course of radiation (fewer, larger doses) with the standard longer course for women who have had breast cancer surgery with implant-based reconstruction. It aims to see if the shorter schedule is just as safe and effective for the chest area, while being more convenient.
ShanghaiAges 18 years+ - NCT05216900Recruiting
Breast reconstruction with radiation given before surgery
This study looks at how breast reconstruction works when radiation is planned around the time of surgery, including in some people before surgery depending on lymph node results. It may help improve safety and outcomes for people needing mastectomy and chest/radiation therapy.
Bilthoven, UtrechtAges 18–75 - NCT07829848Recruiting
Skip extra radiation for breast cancer patients who respond well to treatment
This trial tests whether women and men with advanced, non-metastatic breast cancer can safely skip an extra radiation boost to the lymph nodes if their tumors respond well to pre-surgery chemotherapy or targeted therapy. The goal is to reduce side effects while keeping cancer control.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07826338Recruiting
Mobile app support for breast cancer patients starting chemotherapy
This study tests a smartphone app that provides support and information to women with breast cancer who are starting chemotherapy for the first time. The app may help manage symptoms and improve your experience during treatment.
Izmir, İzmirAges 18 years+ - NCT07833566Recruiting
Biopsy-site marker placement in breast cancer surgery
This study looks at the safety and usefulness of placing a marker at the biopsy site in women with invasive breast cancer before surgery. It may help ensure the right area is removed during surgery.
Oklahoma City, OklahomaAges 18 years+ - NCT05341492RecruitingEarly Phase 1
CAR-T therapy for EGFR/B7H3-positive lung and triple-negative breast cancer
This early-phase trial tests CAR-T cells designed to find and attack tumors that show EGFR or B7H3 markers. It may help people with advanced lung cancer or triple-negative breast cancer after standard treatments.
Guangzhou, GuangdongAges 18–75 - NCT06472583RecruitingPhase 2
Immunotherapy and radiation before breast cancer surgery
This trial tests giving immunotherapy combined with a precise, high-dose radiation boost before surgery for HER2-negative breast cancer. The goal is to see if this approach can improve outcomes, especially for cancers that are more advanced or have spread to a few other spots in the body.
GliwiceAges 18 years+ - NCT07823660Recruiting
Heart-healthy exercise during breast cancer chemotherapy
This study tests a supervised exercise program for people with breast cancer who are about to start or are already in chemotherapy. The goal is to see if this type of rehabilitation helps keep your heart strong and improves your overall well-being during treatment.
