Recruiting studies
- NCT07357597RecruitingPhase 4
Preventing mouth sores during breast or lung cancer treatment

Tucson, ArizonaAges 18 years+ - NCT07638852RecruitingPhase 2
Combining radiation and targeted drugs for triple-negative breast cancer brain tumors
This trial is testing whether giving radiation therapy along with a combination of chemotherapy (cisplatin or carboplatin), an immunotherapy drug called adebrelimab, and a drug called bevacizumab can better treat triple-negative breast cancer that has spread to the brain. The goal is to see if this combination can shrink or control the brain tumors and improve outcomes.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07605728RecruitingPhase 2
Probiotics to ease stomach problems from breast cancer treatment
This trial tests whether a special probiotic supplement (good bacteria) can reduce belly discomfort caused by abemaciclib, a hormone therapy drug for early breast cancer. You would take the supplement alongside your cancer treatment to see if it helps with stomach side effects.
TaipeiAges 18 years+ - NCT07586215Recruiting
HER2-PET imaging to predict response to T-DXd in advanced breast cancer
This study is testing whether a special PET scan (HER2-PET) can help predict how well the drug T-DXd (also known as Enhertu) might work for your breast cancer. T-DXd is a targeted therapy that delivers chemotherapy directly to cancer cells with certain markers. The trial will check if the scan can identify which patients are more likely to benefit, which could help personalize treatment.
ShanghaiAges 18 years+ - NCT07378306RecruitingPhase 2
Fasting-mimicking diet with chemo-immunotherapy for triple-negative breast cancer
This trial tests whether adding a special low-calorie diet (called a fasting-mimicking diet) to standard chemotherapy and immunotherapy can help treat triple-negative breast cancer before surgery. It aims to see if this combination makes the treatment work better.
Guangzhou, GuangdongAges 18–70 - NCT07369505RecruitingPhase 1
A study of Sapu003 for advanced tumors sensitive to mTOR
This trial tests a new drug, Sapu003, in people with certain advanced cancers that may respond to mTOR-targeted therapy. It is looking at two groups: postmenopausal women with a type of breast cancer (HR+/HER2-), and adults with kidney, liver, neuroendocrine, or TSC-related tumors. The goal is to see if Sapu003 is safe and effective.
AdelaideAges 18 years+ - NCT07243002Recruiting
Patient outcomes with ribociclib or abemaciclib for early breast cancer
This study looks at how women and men with stage II or III HR+ HER2- breast cancer do when they start treatment with ribociclib or abemaciclib (combined with hormone therapy) after surgery. Researchers want to understand real-world experiences and results.
LondonAges 18 years+ - NCT06607757RecruitingPhase 2
Capivasertib plus fulvestrant for high-risk lobular breast cancer
This trial tests adding capivasertib to fulvestrant for women with a certain type of breast cancer (invasive lobular carcinoma) that is hormone-receptor positive and has a high risk of coming back. The treatment is given before surgery to see if it works better than fulvestrant alone.
AugsburgAges 18 years+ - NCT05536128RecruitingPhase 2
Fulvestrant plus DNA damage drugs after CDK4/6 treatment failure
This Phase 2 trial studies whether combining fulvestrant with medicines that block DNA repair can help treat HR+/HER2- metastatic or inoperable breast cancer that has progressed after endocrine therapy plus a CDK4/6 inhibitor. It also aims to check the safety of this combination and see if it can control the cancer for longer.
SeoulAges 19 years+ - NCT07180693Recruiting
Breast cancer that returns after CDK4/6 inhibitor treatment
This study looks at patients whose breast cancer returns after starting a CDK4/6 inhibitor (like abemaciclib or ribociclib) along with hormone therapy. The goal is to understand why the cancer comes back and find better ways to treat it.
Bergamo, ItalyAges 18 years+ - 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 - NCT06966141Recruiting
Real-World Study of Sacituzumab Govitecan for Breast Cancer
This study looks at how well the drug Sacituzumab Govitecan works in real-life settings for people with certain types of advanced breast cancer that have not responded to prior treatments.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06993844RecruitingPhase 1/Phase 2
Study of ETX-636 for advanced solid tumors with PIK3CA mutation
This trial tests an experimental drug called ETX-636 in people whose cancer has a specific gene change (PIK3CA mutation) and has not responded to at least one prior treatment. The goal is to see if the drug can shrink tumors or stop them from growing.
Newport Beach, CaliforniaAges 18 years+ - NCT06750484RecruitingPhase 2
Testing trastuzumab deruxtecan in HER2-zero breast cancer
This trial tests a new drug called trastuzumab deruxtecan (a targeted antibody-drug combination) for people with advanced breast cancer that never showed any HER2 protein (HER2-zero). The goal is to see if it can shrink tumors and improve outcomes for those who have already had standard treatments.
New Haven, ConnecticutAges 18 years+ - NCT06439771RecruitingPhase 2
Testing YL202 for advanced breast cancer
This trial tests a new drug called YL202 for people with advanced breast cancer. It is for those who have already tried certain targeted treatments (HER2 or TROP2 antibody-drug conjugates) and they stopped working. The goal is to see if YL202 can help shrink tumors or slow cancer growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06377852RecruitingPhase 3
CDK4/6 inhibitor dosing study for older adults with metastatic breast cancer
This study tests two targeted therapy drugs, palbociclib and ribociclib, combined with hormone therapy for people aged 60 or older with hormone receptor-positive, HER2-negative metastatic breast cancer. The goal is to see how well this treatment works and to gather information that may help improve dosing for older adults.
Chandler, ArizonaAges 60 years+ - NCT06169371RecruitingPhase 4
Abemaciclib dose escalation for early breast cancer
This study tests whether women with early-stage HR+/HER2- breast cancer can safely take a higher dose of the drug abemaciclib (Verzenio) after surgery. The goal is to keep the treatment as strong as possible while managing side effects.
Chicago, IllinoisAges 18 years+ - 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+ - NCT05146778Recruiting
Opioid-free anesthesia to reduce long-term post-mastectomy pain
This study tests whether a pain-control approach without opioids (strong pain medicines) can lower persistent pain after mastectomy. It may help people avoid long-term pain and opioid side effects.
SeoulAges 19–80 - NCT05464082RecruitingPhase 2
Collect tumor samples to guide early breast cancer recurrence care
This Phase 2 study tests a “precision” approach using tumor sample testing to help predict, prevent, and treat early metastatic recurrence in triple-negative or hormone-receptor–low, HER2-negative breast cancer. If you qualify, you’ll be asked to provide tumor tissue before (or in place of) standard chemotherapy, so researchers can learn which tumor features matter most.
Salt Lake City, UtahAges 18 years+ - NCT05293470Recruiting
Tracking the real-world effects of Piqray in Korea
This study monitors how well and how safely Piqray works for people in Korea in routine care. You may be invited if your breast cancer matches specific genetic and receptor test results and you are starting Piqray for the first time.
