Shanghai, Shanghai MunicipalityAges 18–70 - NCT05076682RecruitingPhase 2
Study for hard-to-treat triple-negative breast cancer that keeps growing
This Phase 2 trial tests a treatment plan for triple-negative breast cancer that has come back or kept progressing after prior immunotherapy (sometimes along with targeted therapy or chemotherapy). It may help by trying to make the cancer more controllable when it has become resistant to earlier treatment.
ShanghaiAges 18–70 - NCT05306041RecruitingPhase 2
Pre-surgery hormone therapy with or without PI3K inhibitor
This trial tests whether giving hormone-blocking treatment before surgery works better when combined with an added targeted drug for certain breast cancers. It may help shrink the tumor and improve outcomes for people whose tumors have specific hormone and genetic features.
Essen, North Rhine-WestphaliaAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Birmingham, AlabamaAges 50–70 - NCT07011654RecruitingPhase 1/Phase 2
Study of two drugs for metastatic triple-negative breast cancer
This trial tests a combination of two drugs, naxitamab and sacituzumab govitecan, for people with metastatic triple-negative breast cancer that has already been treated with at least one chemotherapy. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Houston, TexasAges 18 years+ - NCT06127979Recruiting
Hormone therapy before surgery for breast cancer
This study looks at how a hormone-blocking medicine (endocrine therapy) given before surgery affects a marker called Ki67 in your breast cancer cells. The goal is to see if the medicine can slow the growth of the cancer, which may help doctors choose the best treatment for you.
New York, New YorkAges 18 years+ - NCT06923527RecruitingPhase 2
Testing ctDNA to start elacestrant in early breast cancer
This trial tests whether the drug elacestrant can help prevent recurrence in people with a type of breast cancer (ER+/HER2-) who have finished hormone therapy and have signs of cancer DNA in their blood (ctDNA positive) but no visible spread on scans.
New Haven, ConnecticutAges 18 years+ - NCT03643861Recruiting
Radiation after lumpectomy for certain early breast cancers
This trial tests a short, highly targeted radiation plan given in five sessions after lumpectomy for early-stage breast cancer. It may help treat the remaining breast area while aiming to limit exposure to healthy tissue.
Birmingham, AlabamaAges 18–99 - NCT07540572RecruitingPhase 1
Testing IDE574 safety and effectiveness in advanced solid tumors
This early-stage trial tests a new drug called IDE574 to see if it is safe and effective in treating advanced cancers that have spread or stopped responding to standard treatments. The trial focuses mainly on hormone-receptor positive breast cancer, but also includes lung, prostate, and colorectal cancers.
Plantation, FloridaAges 18–99 - NCT04469296Recruiting
Diet changes before surgery for hormone-receptor breast cancer
This trial tests whether changing your diet before your breast surgery can help people with early, hormone-receptor (ER/PR+) breast cancer. It focuses on patients who have not started treatment yet and want to keep surgery as the main treatment.
Montpellier, HeraultAges 18–80 - NCT05212454RecruitingPhase 3
Capecitabine added after surgery for high-risk ER-positive breast cancer
This Phase 3 study tests whether adding capecitabine (a chemotherapy pill) after breast cancer surgery can lower the chance the cancer comes back. It targets people with hormone-receptor–positive and HER2-negative breast cancer who are considered “high risk.”
Hanzhou, ZhejiangAges 18–70 - NCT05891093RecruitingPhase 3
Fluzoparib plus hormone therapy after surgery for breast cancer
This Phase 3 trial tests whether fluzoparib added to standard hormone (endocrine) therapy after early breast cancer surgery can improve outcomes and safety. It may help patients whose tumors are ER-positive, HER2-negative, and a specific SNF3 subtype.
Beijing, Beijing MunicipalityAges 18–70 - NCT06387628RecruitingPhase 2
LM-108 with immunotherapy for advanced triple-negative breast cancer
This trial tests a new drug called LM-108 combined with a PD-1 inhibitor (a type of immunotherapy) for people with triple-negative breast cancer that has come back or spread. It aims to see if this combination can help shrink tumors or slow the disease.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06548919Recruiting
Treatment patterns for ESR1-mutated advanced breast cancer
This study looks at how Chinese patients with a specific gene change (ESR1 mutation) in ER-positive, HER2-negative advanced breast cancer are currently being treated. It will help doctors understand what treatments work best for people whose cancer has stopped responding to hormone therapy.
Suzhou, JiangsuAges 18 years+ - NCT04872166RecruitingPhase 1
BTX-A51 for advanced solid tumors and breast cancer patients
This Phase 1 study tests BTX-A51, an experimental treatment, in people with advanced cancers that can’t be cured with standard options. It mainly focuses on safety, side effects, and whether the drug can start helping certain tumors.
Lake Mary, FloridaAges 18 years+ - NCT07237256RecruitingPhase 3
Testing less chemo for HR+ HER2- breast cancer with ribociclib
This trial tests whether some people with hormone receptor-positive, HER2-negative early breast cancer can safely receive less chemotherapy when also taking the targeted drug ribociclib after surgery. You may qualify if you have a specific stage of breast cancer and are planning to take hormone therapy for at least 5 years.
AmiensAges 18 years+ - NCT06976944RecruitingPhase 2
