Chemo plus immunotherapy for early HR+/HER2- breast cancer
This trial tests adding an immunotherapy drug (serplulimab) to standard chemotherapy for early-stage HR+/HER2- breast cancer. The goal is to see if the combination works better than chemo alone before surgery.
ZhengzhouAges 18 years+ - NCT06217185RecruitingPhase 4
Pyrotinib and trastuzumab with chemo for HER2+ advanced breast cancer
This trial tests a combination of two targeted medicines (pyrotinib and trastuzumab) with chemotherapy to treat HER2-positive advanced breast cancer that has returned or spread after stopping trastuzumab.
Shijiazhuang, HebeiAges 18–70 - NCT05834764RecruitingPhase 2
Pyrotinib for high-risk HER2-positive early breast cancer
This Phase 2 trial tests pyrotinib, a HER2-targeted cancer medicine, in people with high-risk, HER2-positive breast cancer after surgery. It aims to lower the chance the cancer comes back, especially when standard treatment did not fully clear the tumor.
Nanjing, JiangsuAges 18–75 - NCT05398861RecruitingPhase 2
Testing utidelone plus bevacizumab for HER2-negative advanced breast cancer
This trial studies whether utidelone combined with bevacizumab can shrink tumors and slow progression in women with advanced HER2-negative breast cancer that has already been treated at least twice. It may help people who have limited options after earlier chemotherapy and/or hormone (endocrine) treatments.
Zhengzhou, HenanAges 18–70 - NCT05464810RecruitingEarly Phase 1
Letrozole with or without a cholesterol drug for early breast cancer
This early-phase study tests whether adding simvastatin to letrozole can improve outcomes in people with stage I–III breast cancer that grows with hormone signals (hormone receptor positive) and does not have HER2. It looks mainly at whether the approach is safe and useful for this specific breast cancer type.
Atlanta, GeorgiaAges 18 years+ - NCT04254263RecruitingPhase 3
Pyrotinib after breast cancer therapy for HER2-positive early disease
This trial studies whether adding pyrotinib after standard treatment helps prevent breast cancer from coming back in people with HER2-positive early-stage breast cancer. You may be eligible if you finished chemotherapy plus trastuzumab and still had signs of cancer in the tissue removed during surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06470347RecruitingPhase 1/Phase 2
Testing Pyrrolitinib After Trastuzumab for HER2+ Breast Cancer
This study tests if taking pyrrolitinib (a targeted medicine) can further reduce the risk of breast cancer returning in patients with HER2-positive early breast cancer who have already received trastuzumab after surgery.
Zunyi, GuizhouAges 18–75 - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer
This study compares a new drug called zanidatamab against trastuzumab (Herceptin), both given with a chemotherapy of your doctor's choice. It is for people with HER2-positive breast cancer that has spread and who have already tried T-DXd treatment.
Phoenix, ArizonaAges 18 years+ - NCT04281641Recruiting
Testing marker-guided treatment before surgery for HER2-positive breast cancer
This trial studies how well a HER2-focused treatment plan works before surgery (“neoadjuvant” therapy) for operable HER2-positive breast cancer. It also uses tumor tissue tests to find markers that may predict who benefits most.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05901428RecruitingPhase 3
Check if two breast cancer treatments work better after surgery
This trial compares two treatment approaches in people with high-risk hormone-positive, HER2-negative breast cancer that has spread to certain lymph nodes. It looks at which option works best to lower cancer returning and to control the disease after surgery and initial chemotherapy.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06992882RecruitingPhase 3
Comparing two chemo regimens with Herceptin for early breast cancer
This trial tests if taking oral chemotherapy pills with trastuzumab (Herceptin) works as well as IV chemo (paclitaxel) with Herceptin after surgery for HER2-positive, lymph node-negative early breast cancer. It aims to find a more convenient treatment option.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07506876RecruitingPhase 2
Combined hormone and chemo before surgery for HER2+ breast cancer
This trial tests combining hormone therapy with chemotherapy and targeted therapy before surgery for a type of breast cancer that is both hormone-receptor-positive (HR+) and HER2-positive. The goal is to see if this combination works better than standard treatment.
Gresham, OregonAges 18 years+ - NCT07132749Enrolling by invitation
NEPA for nausea prevention during T-DXd in advanced HER2+ or HER2-low breast cancer
This trial tests whether the anti-nausea combination NEPA (netupitant and palonosetron) can prevent nausea and vomiting caused by the targeted therapy T-DXd in people with advanced HER2-positive or HER2-low breast cancer. It may help you if you are about to start T-DXd for the first time and want to manage treatment side effects.

Elizabeth, New JerseyAges 18–90 - NCT07263425RecruitingPhase 2
Study of thiotepa and trastuzumab for breast cancer that spread to the lining of the brain and spinal cord
This trial tests a combination of two drugs given through a special port in the head to treat HER2-positive breast cancer that has spread to the layer covering the brain and spinal cord (leptomeningeal metastasis). It aims to see if this treatment is safe and effective.
Nanjing, JiangsuAges 18–75 - NCT05812807RecruitingPhase 3
Pembrolizumab versus monitoring after triple-negative breast cancer response
This trial checks whether giving pembrolizumab (an immunotherapy) after surgery helps people with triple-negative breast cancer reduce the chance of the cancer coming back, compared with close monitoring only. It’s for patients who had no remaining invasive cancer after neoadjuvant chemotherapy plus pembrolizumab.
Birmingham, AlabamaAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
