Recruiting studies
- NCT06162559RecruitingPhase 1
Targeted therapy before surgery for HER2+ breast cancer
This trial tests a combination of three targeted drugs (trastuzumab, pertuzumab, and tucatinib) without chemotherapy before surgery for HER2-positive breast cancer. It aims to see if this approach can shrink tumors effectively while avoiding chemotherapy side effects.
AmsterdamAges 18 years+ - NCT07658170Recruiting
Fat graft with platelet-rich fibrin for breast reconstruction after lumpectomy
This trial tests using a patient's own fat plus a special blood product (platelet-rich fibrin) to rebuild the breast right after a lumpectomy for breast cancer. It may help improve healing and appearance for women with early-stage, hormone-sensitive breast cancer.
Saint PetersburgAges 18–69 - NCT07601178RecruitingPhase 2
Immunotherapy and targeted drugs for advanced triple-negative breast cancer
This trial tests a combination of four drugs—two immunotherapies (QL1706), an anti-angiogenic agent (anlotinib), and chemotherapy (nab-paclitaxel)—as a first-line treatment for advanced triple-negative breast cancer. The goal is to see if this combination slows or stops cancer growth better than standard treatment alone.
Nanjing, JiangsuAges 18–75 - NCT07016399RecruitingPhase 2
Darolutamide before surgery for AR-positive triple-negative breast cancer
This trial tests a drug called darolutamide, alone or with standard chemotherapy, before surgery for a type of breast cancer that is triple-negative but has a high level of the androgen receptor (AR). It is for people with stage II or IIIA breast cancer that can be removed surgically.
Nashville, TennesseeAges 18 years+ - NCT07581834RecruitingPhase 2
Dalpiciclib plus hormone therapy for early hormone-positive breast cancer
This study tests whether adding a new drug called dalpiciclib to standard hormone therapy improves outcomes for women with early-stage breast cancer that is hormone-receptor positive. The goal is to see if this combination is more effective and safe than hormone therapy alone.
Fuzhou, FujianAges 18 years+ - NCT06450873RecruitingPhase 2
Turkey tail mushroom before breast cancer surgery
This trial tests whether taking a turkey tail mushroom supplement before breast cancer surgery can help the immune system fight the cancer. It is for post-menopausal women with a common type of breast cancer (ER-positive, HER2-negative) that is growing at a moderate or faster rate (Ki-67 score of 10% or more).
Scottsdale, ArizonaAges 18 years+ - NCT04893109RecruitingPhase 2

This Phase 2 study tests two different medicines given after breast surgery to reduce the risk of cancer coming back. It is only for people with early-stage HER2-positive breast cancer with limited or no lymph node spread.
San Francisco, CaliforniaAges 18 years+ - NCT05983107RecruitingPhase 2
Chidamide/Everolimus for advanced breast cancer
This trial tests a combination of two drugs, chidamide and everolimus, for people with advanced HR+/HER2- breast cancer. It aims to see if the combination works for tumors with or without a PIK3CA gene mutation. You may be able to join if you've had previous treatment with CDK4/6 inhibitors and up to two prior chemotherapies.
Beijing, Beijing MunicipalityAges 18–75 - NCT06605521Recruiting
Study on removing lymph nodes above the collarbone for breast cancer

Zhengzhou, HenanAges 18–80 - 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 - NCT04481932RecruitingPhase 2
Trastuzumab with chemo for HER2-positive breast cancer
This Phase 2 study tests whether adding trastuzumab (a targeted antibody) given with chemo and extra drugs can better treat certain HER2-positive, locally advanced or inflammatory breast cancers. It may help by improving cancer control in people who have not had prior anti-cancer treatment for their breast cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT05447702RecruitingPhase 2
Testes pre-surgery treatment for triple-negative breast cancer
This trial studies giving camrelizumab plus apatinib and chemotherapy before surgery for triple-negative breast cancer. The goal is to shrink the tumor and improve outcomes by testing a combination of immune and targeted medicines along with chemotherapy.
Chengdu, SichuanAges 18–75 - NCT07810088RecruitingPhase 2
Dalpiciclib with hormone therapy and blood pressure drug for advanced breast cancer
This trial is testing a new combination of medicines — a CDK4/6 inhibitor (dalpiciclib) plus hormone therapy and a blood pressure drug (olmesartan) — as a first treatment for advanced hormone-positive breast cancer. The goal is to see if this combination helps slow or shrink the cancer better than standard care.
Wuhan, HubeiAges 18–75 - NCT07776951Recruiting
Physical activity for breast cancer patients during treatment
This study tests whether a supervised physical activity program can help breast cancer patients reduce inflammation and improve health during neoadjuvant treatment (chemotherapy or immunotherapy given before surgery). The goal is to see if exercise can improve treatment outcomes and overall well-being.
MilanAges 18 years+ - NCT07671885RecruitingPhase 3
Hormone therapy before surgery for premenopausal breast cancer
This trial tests if giving hormone-blocking pills before surgery can help guide which treatments you need after surgery. It is for premenopausal women with early-stage, hormone-sensitive breast cancer.
AkitaAges 18 years+ - NCT07616427RecruitingPhase 2
New drug plus hormone therapy for HER2-positive breast cancer
This study tests a new drug called fovinaciclib combined with hormone therapy and HER2-targeting drugs for early-stage breast cancer that has specific markers (HR-positive and HER2-positive). The goal is to shrink tumors before surgery and improve outcomes.
Nanjing, JiangsuAges 18–75 - NCT07457359RecruitingPhase 2
Toripalimab plus radiation for chemo-resistant triple-negative breast cancer
This trial tests if combining an immunotherapy drug (toripalimab) with targeted radiation (SBRT) can help people with triple-negative breast cancer that did not shrink after initial chemotherapy. It aims to improve outcomes before surgery.
HangzhouAges 18–75 - NCT06793553RecruitingPhase 2
Induction chemo then immunotherapy for PD-L1 positive triple negative breast cancer
This trial tests a two-step approach: first a short course of chemotherapy (paclitaxel and bevacizumab), followed by a combination of immunotherapy (atezolizumab) and a different chemotherapy (nab-paclitaxel). It's for people with advanced triple-negative breast cancer that has spread or cannot be removed, and whose tumors have a specific marker called PD-L1. The goal is to see if this sequence works better than standard treatments.
