Recruiting studies
- NCT06678269RecruitingPhase 1

Basking Ridge, New JerseyAges 18 years+ - NCT06679036RecruitingPhase 1/Phase 2
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.
Harbin, HeilongjiangAges 18–75 - NCT06681064Recruiting

This study looks at how breast cancer changes while you are receiving chemotherapy or targeted therapy before surgery. The goal is to better understand which treatments work best for different types of breast cancer.
LondonAges 18 years+ - NCT06690840RecruitingPhase 2
Atezolizumab plus chemo for advanced triple-negative breast cancer
This trial tests atezolizumab (an immunotherapy) plus chemotherapy to activate immune cells in people with triple-negative breast cancer that has spread or cannot be removed. It is for those who have had immunotherapy before during early treatment but not for advanced disease.

Monitoring test for CDK4/6 drugs in metastatic breast cancer
This study follows people with hormone receptor–positive, HER2-negative metastatic breast cancer who are taking CDK4/6 inhibitor treatment (with or without an added blood test called DiviTum®). The goal is to see how well the standard treatment is working and whether DiviTum® (a serum TK1 activity test) can help guide monitoring.
St Louis, MissouriAges 18 years+ - NCT06713161Recruiting
New dye to spot breast cancer during surgery
This study tests a special dye that helps surgeons see breast cancer tissue and nearby lymph nodes more clearly during surgery. The goal is to make sure all cancer is removed while sparing healthy tissue.
Kunming, YunnanAges 18–75 - NCT06715826RecruitingPhase 1/Phase 2
Imaging breast cancer with a targeted radioactive tracer
This study is testing a new imaging method that uses a radioactive tracer to find breast cancer cells. It may help doctors see the cancer more clearly.
Shanghai, Shanghai MunicipalityAges 18–75 - 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 - NCT06725940Recruiting
PET scan to check treatment response in breast cancer
This trial uses a special PET scan to see how well your breast cancer is responding to neoadjuvant therapy (treatment given before surgery). The goal is to help doctors personalize your care by checking if the cancer is shrinking.
ShanghaiAges 18–65 - NCT06726889Recruiting
Improving oral medication adherence in metastatic breast cancer
This study tests a program to help people with metastatic breast cancer take their oral medications as prescribed. It uses a smartphone app to track and support medication adherence, which may improve treatment outcomes.
MilanAges 18 years+ - NCT06727227Recruiting
Study of Enhertu for HER2-low breast cancer
This study looks at how well the drug Enhertu works for patients with HER2-low breast cancer that has spread. If you are already planning to start Enhertu, researchers will collect data from your regular care to learn more about its effectiveness.
Panagyurishte, PazardzhikAges 18 years+ - NCT06732323RecruitingPhase 3
Study of ESG401 for triple-negative breast cancer that has spread
This trial tests a new drug, ESG401, for people with triple-negative breast cancer that has come back or spread and cannot be removed by surgery. It compares ESG401 to standard chemotherapy options to see which works better.
BeijingAges 18 years+ - NCT06732336RecruitingPhase 1/Phase 2
PET scan for HER2-low breast cancer
This trial uses a special PET scan to see if your breast cancer has low levels of a protein called HER2. This could help doctors choose the right treatment for you.
Sherbrooke, QuebecAges 18 years+ - 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+ - NCT06738966RecruitingPhase 1
BL0175 for advanced HR-positive breast or gynecologic cancer
This trial tests a new drug called BL0175 for women with certain types of advanced breast, ovarian, or endometrial cancer that have stopped responding to hormone therapy. The goal is to see if the drug can help shrink tumors or slow down the cancer.
Changchun, JilinAges 18 years+ - NCT06739655Recruiting
Radiation before surgery with breast reconstruction
This trial tests whether giving radiation therapy before surgery (instead of after) is safe and effective for women with breast cancer who also want immediate breast reconstruction. It could help avoid the need for a second surgery and improve recovery.
Edegem, AntwerpenAges 18 years+ - NCT06746688RecruitingPhase 1
Safety study of ES2B-C001 for HER2-positive metastatic breast cancer
This trial tests a new drug called ES2B-C001, with or without an adjuvant, to see if it is safe for people with HER2-positive breast cancer that has spread and has not responded to previous treatments.
GrazAges 18 years+ - NCT06756932RecruitingPhase 1
Bcl-2 inhibitor combo for advanced HR+ breast cancer
This trial tests a new Bcl-2 inhibitor (BGB-21447) combined with other therapies for advanced HR+/HER2- breast cancer that has already been treated with hormone therapy and a CDK4/6 inhibitor. It aims to see if these combinations are safe and effective.

Blood test for gene changes in advanced breast cancer
This trial uses a simple blood test to look for two specific gene changes (ESR-1 and gBRCA) in people with hormone receptor-positive, HER2-negative breast cancer that has spread. It aims to detect these mutations earlier and help guide future treatment decisions.
Milan, ItalyAges 18 years+ - NCT06765590Recruiting
Paclitaxel (albumin-bound) bioequivalence study in breast cancer
This study tests whether a new version of paclitaxel (albumin-bound) works the same as the approved version in people with breast cancer. It's for patients whose cancer has spread or returned after other treatments, or those for whom this drug is recommended by treatment guidelines.
