Recruiting studies
- NCT06078384RecruitingPhase 2
Pembrolizumab and chemo for early-stage triple-negative breast cancer
This trial studies whether adding pembrolizumab (an immunotherapy) to standard chemotherapy after surgery can improve outcomes for people with early-stage triple-negative breast cancer. The treatment you receive depends on the level of immune cells (TILs) found in your tumor.
AmiensAges 18 years+ - NCT06134375RecruitingPhase 1/Phase 2
TM plus capecitabine for triple-negative breast cancer
This trial tests a drug called tetrathiomolybdate (TM) combined with capecitabine for people with triple-negative breast cancer who still have cancer cells after standard chemotherapy and surgery. The goal is to see if this combination can help prevent the cancer from coming back.
Indianapolis, IndianaAges 18–80 - NCT06139107RecruitingPhase 1
Radiation and abemaciclib plus letrozole before breast cancer surgery
This trial combines a short course of radiation before surgery with two oral medications (abemaciclib and letrozole) to treat early-stage, hormone-sensitive breast cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Belleville, New JerseyAges 60 years+ - NCT06165900RecruitingPhase 2
Radiation plus immunotherapy and chemo before surgery for triple-negative breast cancer
This trial tests combining stereotactic radiation therapy with immunotherapy (adebrelimab) and chemotherapy (nab-paclitaxel and carboplatin) before surgery for early or locally advanced triple-negative breast cancer. The goal is to see if this combination improves treatment response.
Shenyang, LiaoningAges 18–75 - NCT06214598Recruiting
Anti-inflammatory diet for breast cancer patients on hormone therapy
This study tests whether a special anti-inflammatory diet can help reduce side effects in breast cancer survivors who are taking aromatase inhibitors after menopause. You would be randomly assigned to either follow the diet for 6 months or continue your usual diet, and your health will be monitored.
BelgradeAges 45–70 - NCT06222957Recruiting
How HER2 affects brown fat in breast cancer patients
This study looks at how a protein called HER2 affects brown fat activity in women with breast cancer. Brown fat helps burn calories and may influence treatment outcomes. You will be assigned to one of two groups based on your cancer's HER2 status, and the study will measure how your brown fat responds to cold.
CopenhagenAges 18 years+ - NCT06230185Recruiting
Blood test to monitor treatment response in triple-negative breast cancer
This trial is testing whether a blood test can track how well chemotherapy is working in people with early-stage triple-negative breast cancer. You would provide blood samples before and during treatment, and the results may help your doctor understand your response better.
Tucson, ArizonaAges 18 years+ - NCT06533384RecruitingPhase 3
PARP inhibitor or chemo plus immunotherapy after surgery for high-risk TNBC
This trial tests whether adding a PARP inhibitor or capecitabine (chemo) to a PD-1 inhibitor (immunotherapy) after surgery helps prevent triple-negative breast cancer from coming back. It's for people with high-risk disease who have completed initial treatment.
Guangzhou, GuangdongAges 18–70 - NCT06627712RecruitingPhase 3
SBRT with immunotherapy and chemo for early-stage triple-negative breast cancer
This trial tests whether combining targeted radiation (SBRT) with immunotherapy (PD-1 inhibitor) and chemotherapy can improve outcomes for people with early-stage triple-negative breast cancer that has not spread far. It aims to find a more effective treatment option.
Sichuan, ChengduAges 18–65 - NCT06643585RecruitingPhase 3
Comparing T-DXd to standard therapy for molecular relapse in early breast cancer
This trial compares a new drug called Trastuzumab-Deruxtecan (T-DXd) to standard treatment for people with early breast cancer whose cancer has come back at a molecular level (detected by a blood test) but hasn't spread to other parts of the body. The goal is to see if T-DXd can prevent the cancer from returning.
UlmAges 18–75 - NCT06666439Recruiting
Tracking lobular breast cancer with a blood test
This study is testing a new blood test that looks for cancer DNA to track how lobular breast cancer responds to treatment. It is for people whose cancer has spread and who have not yet started treatment for the spread.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06703567Recruiting
Helping patients understand gene test results for breast cancer
This study tests a tool to help people newly diagnosed with early-stage breast cancer better understand their gene test results. It is for patients who haven't yet decided about chemotherapy and want to learn more about their options.
MilanAges 18 years+ - NCT06709651Recruiting
Gut bacteria treatment for triple-negative breast cancer
This trial tests whether a treatment that targets your gut bacteria (microbiome) can help fight triple-negative breast cancer before surgery. It is for people with newly diagnosed, untreated triple-negative breast cancer that has not spread far.
Cork, MunsterAges 18 years+ - NCT06735131RecruitingPhase 2
Radiation and immunotherapy for advanced triple-negative breast cancer
This study tests a combination of radiation therapy and immunotherapy for people with advanced triple-negative breast cancer who haven't had chemotherapy for their advanced disease. It aims to see if adding radiation to standard chemotherapy can help shrink tumors and improve outcomes.
Guangzhou, GuangdongAges Any age - NCT06786026RecruitingPhase 2
Drug combo plus chemotherapy for first-line advanced triple-negative breast cancer
This trial tests whether adding an experimental immunotherapy drug (QL1706) with or without bevacizumab to standard chemotherapy can help people with advanced triple-negative breast cancer that hasn't been treated yet. It aims to improve outcomes for patients who have already had earlier treatment but whose cancer has come back or spread.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06813456Recruiting
Improving HER2 detection in breast cancer with new testing method
This trial studies a more precise way to measure HER2 levels in breast cancer tissue. It may help identify patients whose cancer is HER2-low or HER2-zero, so they can get more targeted treatment.
Bologna, BolognaAges 18 years+ - NCT06963905RecruitingPhase 1/Phase 2
Testing a combination drug for triple-negative breast cancer
This trial is testing a combination of three drugs—sacituzumab govitecan, nivolumab, and relatlimab—for people with metastatic triple-negative breast cancer that has progressed after at least one prior therapy. You may qualify if you have this specific type of breast cancer and have received certain prior treatments.
New Haven, ConnecticutAges 18 years+ - NCT07074106RecruitingPhase 2
Lower chemo with tumor-fighting cells for stage I-II breast cancer
This trial tests whether giving less chemotherapy is safe when patients have high levels of tumor-infiltrating lymphocytes (TILs) — a sign that the body's immune system is already fighting the cancer. It is for women with early-stage, triple-negative breast cancer.
BrasíliaAges 18 years+ - NCT07283692RecruitingPhase 2
New drug combo for triple-negative breast cancer before surgery
This trial tests a new drug, serplulimab, combined with standard chemotherapy (paclitaxel and carboplatin) given before surgery for triple-negative breast cancer. The goal is to see if this combination can shrink tumors more effectively.
ShanghaiAges 18–70 - NCT07290153Recruiting

Shanghai, Please SelectAges 18–70 - NCT07332975Recruiting
Blood test for tumor DNA in early triple-negative breast cancer
This study is for people with early-stage triple-negative breast cancer (TNBC) that has not been treated yet. Researchers want to see if tracking tumor DNA in your blood can help guide treatment decisions. You would receive standard chemotherapy and surgery, plus give blood samples.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT07351487RecruitingPhase 2
Chemo plus immunotherapy and anti-angiogenic drug for TNBC before surgery
This trial tests whether adding sintilimab (an immunotherapy) and bevacizumab (a drug that blocks blood supply to tumors) to standard chemotherapy before surgery can improve outcomes for women with stage II or III triple-negative breast cancer. It may help your immune system fight the cancer more effectively.
