- NCT06636981RecruitingPhase 2
Combination therapy for advanced triple negative breast cancer
This trial tests a new combination of a vitamin A derivative (all-trans retinoic acid), an immunotherapy drug (toripalimab), and chemotherapy for people with advanced triple negative breast cancer that cannot be removed by surgery or has spread. The goal is to see if this combination helps shrink or control the cancer better than current treatments.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06998108RecruitingPhase 3
A new drug with fulvestrant for HR+/HER2- advanced breast cancer
This trial tests a new investigational drug called BEBT-209 combined with fulvestrant (a hormone therapy) versus placebo with fulvestrant for people with a type of breast cancer that is hormone receptor-positive and HER2-negative. It is for those whose cancer has worsened after previous hormone therapy and has spread locally or to other parts of the body.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer

Nanchang, JiangxiAges 18–75 - NCT06878625RecruitingPhase 2
Trop-2 drug combo for advanced triple-negative breast cancer
This trial tests a new drug combination (Trop-2 antibody-drug conjugate plus other therapies) for advanced triple-negative breast cancer that has spread or come back. It may offer a new option for people who have had only 1–2 prior chemotherapies and have not used immunotherapy or anti-angiogenic drugs before.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT06791161Enrolling by invitation
Adjuvant therapy study for BRCA1/2 positive breast cancer
This study tests if additional treatment after surgery helps prevent breast cancer from returning. It is for people with hormone receptor-positive, HER2-negative breast cancer who have a BRCA1 or BRCA2 gene mutation and a high risk of recurrence.
Beijing, Beijing MunicipalityAges 18–75 - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT06417801Recruiting
Study of ESR1 gene changes in blood in advanced breast cancer
This study looks for changes in the ESR1 gene in the blood of people with advanced HR+/HER2- breast cancer. It compares these blood test results with tumor tissue results to learn more about the cancer.
Salvador, Estado de BahiaAges 18–100 - NCT07173751RecruitingPhase 3
Pumitamig for advanced triple-negative breast cancer
This study tests a new drug called pumitamig for people with a type of breast cancer that is triple-negative or has very low hormone receptors and has come back or spread. It aims to see if pumitamig works better than standard treatment and how safe it is for people who cannot get PD(L)-1 immunotherapy with chemo.
Springdale, ArkansasAges 18 years+ - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
This trial tests a cancer antibody-drug combination plus pembrolizumab (immunotherapy) versus standard treatment. It’s for people with triple-negative breast cancer that still has invasive disease in the breast or lymph nodes after surgery and chemotherapy before surgery.
Birmingham, AlabamaAges 18 years+ - NCT06671262RecruitingPhase 2
Immunotherapy plus radiation before breast cancer surgery
This trial tests combining two treatments—an immunotherapy drug (Toripalimab) and radiation—before surgery for a certain type of breast cancer (HR+, HER2-negative) that has spread to lymph nodes. The goal is to see if this combination helps shrink the tumor more than standard therapy alone.
Hangzhou, ZhejiangAges 18–85 - NCT06234137Recruiting
Chemo plus targeted therapy for advanced HER2+ breast cancer
This trial tests a combination of chemotherapy (docetaxel and carboplatin) plus two targeted drugs (Inetetamab and Pyrotinib) for people with locally advanced HER2-positive breast cancer that has not spread to other parts of the body. The goal is to see if this powerful combo can shrink the tumor before surgery or other treatments.
Wenzhou, ZhejiangAges 18–75 - NCT06618287RecruitingPhase 1/Phase 2
Testing BMS-986507 for advanced lung and breast cancers
This study tests a new drug called BMS-986507, given in different combinations, for people with advanced solid tumors (lung cancer or breast cancer that has spread). It looks at safety, how the drug works in the body, and if it helps shrink tumors.
Birmingham, AlabamaAges 18 years+ - NCT05981014RecruitingPhase 1/Phase 2
Immune cells from lymph nodes for HER2-negative breast cancer
This trial tests whether taking immune cells from your lymph nodes and giving them back to you can help shrink breast cancer that has not responded fully to initial chemotherapy. It is for women with HER2-negative breast cancer who have had stable disease after two cycles of a standard chemotherapy combination.
Guangzhou, GuangdongAges 18–70 - NCT05981001RecruitingPhase 1/Phase 2
Experimental cell therapy for advanced HER2-negative breast cancer
This study tests a new treatment for advanced HER2-negative breast cancer. Doctors will take immune cells from lymph nodes near your tumor, grow them in a lab, and then give them back to you along with chemotherapy and immunotherapy. This approach aims to help your body fight the cancer more effectively.
Guangzhou, GuangdongAges 18–70 - NCT06121557RecruitingPhase 1
Immune cells from lymph nodes for advanced HER2-negative breast cancer
This trial tests a treatment using your own immune cells taken from lymph nodes near the tumor. The cells are grown in a lab and given back to you to fight cancer, along with another drug chosen by your doctor.
Guangzhou, GuangdongAges 18–70 - NCT06121570RecruitingPhase 1
Study of immune cells from lymph nodes for HER2-negative breast cancer
This trial tests whether using a patient's own immune cells from lymph nodes near the tumor, given as a treatment before surgery, can help shrink HER2-negative breast cancer. It is for people whose cancer has not responded fully to two cycles of initial chemotherapy.
Guangzhou, GuangdongAges 18–70 - NCT07088263RecruitingPhase 3
Adaptive Chemotherapy for Advanced Breast Cancer
This trial tests a new approach to chemotherapy that adapts over time for people with advanced breast cancer that has not responded to first-line treatment. It is designed to personalize treatment based on how the cancer responds, potentially improving outcomes with fewer side effects.
Guangzhou, GuangdongAges 18–75 - NCT05472792RecruitingPhase 2
Testing breast radiation after lumpectomy with or without hormone pills
This Phase 2 trial compares different “after-surgery” treatment plans for certain older women with hormone-sensitive early breast cancer. It looks at whether a standard hormone-pills approach or a faster, smaller-area radiation approach (given after lumpectomy) works best to prevent cancer coming back.
Chapel Hill, North CarolinaAges 65 years+ - NCT07748598Recruiting
Brain scan monitoring for HER2-positive breast cancer
This study is testing regular MRI brain scans to find any brain metastases early in people with HER2-positive breast cancer that has spread. It aims to see if early detection can help guide treatment and improve outcomes.
LiverpoolAges 16 years+ - NCT07084558Recruiting
Testing treatment guided by tumor DNA for hormone positive breast cancer
This trial tests whether using a blood test (circulating tumor DNA) can help guide chemo and hormone therapy for early-stage, hormone receptor positive and HER2 negative breast cancer. The goal is to tailor treatment to your tumor's response, potentially reducing unnecessary side effects.
Vienna, AustriaAges 18–100 - NCT05899387Recruiting
Study fluid after breast surgery
This study looks at a problem called seroma, which is fluid buildup, after certain breast surgeries. It compares different situations where implants or tissue expanders are used, to better understand what to expect and how to manage it.
Augsburg, BavariaAges 18 years+ - 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.

Study of Sac-TMT in Early High-Risk Breast Cancer
This study tests a new drug called Sacituzumab Tirumotecan (Sac-TMT) for people with early-stage, high-risk breast cancer that hasn't spread. The drug is given before surgery to see if it can shrink tumors and improve outcomes.
