Recruiting studies
- NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Birmingham, AlabamaAges 18 years+ - NCT00899301Recruiting
Banking breast cancer and related tissue samples for future studies
This study collects and stores tissue and fluid samples from people with a breast lump or breast cancer so researchers can study cancer biology in the future. It may help future patients by allowing better lab tests and research on why breast cancer starts, grows, and comes back.
Nashville, TennesseeAges 18 years+ - NCT00451022Recruiting
Follow-up study for people who received gene-carrying viral vaccines
This is a follow-up study for adults who previously received certain viral vaccines that carry genes (such as vaccinia or fowlpox) through NCI trials or partner sites. The goal is to store and use your leftover samples for future research that may help doctors understand these treatments better.
Bethesda, MarylandAges 18 years+ - NCT00034216Recruiting
Blood Collection Study for Cancer Patients and Healthy Volunteers
This study collects blood samples from people with cancer and healthy volunteers to help researchers understand cancer better. Your blood will be used for laboratory studies that may improve future cancer treatments.
Bethesda, MarylandAges 18 years+ - NCT07501637Recruiting
Mind-body group support for young breast cancer survivors
This study tests a mind-body group program to help young breast cancer survivors manage stress and emotional distress. It includes a virtual workshop, weekly group sessions, and daily practices to improve well-being.
Birmingham, AlabamaAges 18–50 - NCT02869607Recruiting
Breast cancer database for people with breast cancer
This study collects information from people diagnosed with breast cancer to help researchers understand outcomes and treatment patterns. You may or may not receive a new treatment—often it’s about using existing clinical data.
Marseille, Bouches du RhoneAges 18 years+ - NCT05057598Recruiting
Online study for women with breast cancer experiences
This study asks women with breast cancer to take part in an online, before-and-after research project. It may help researchers understand your experiences and improve support for people living with breast cancer, including those with relapse or spread to other parts of the body.
Milan, MIAges 18–90 - NCT05334459Recruiting
Radiation and medicines after surgery for new metastatic breast cancer
This trial looks at giving radiation and anti-cancer medicines after surgery to treat newly diagnosed (de novo) metastatic breast cancer. It may help patients by improving local control of the breast area while also treating cancer throughout the body.
AnkaraAges 18–80 - NCT05491395Recruiting
Radiation after mastectomy with breast implant reconstruction
This trial studies a radiation schedule given after breast cancer surgery when your breast was rebuilt right away with a prosthesis (implant or similar). It aims to see whether this “hypofractionated” (fewer, larger treatment sessions) radiation approach is appropriate for patients who need additional (adjuvant) radiation to reduce recurrence risk.
Barretos, São PauloAges 18 years+ - NCT04263298RecruitingPhase 3
Fulvestrant or capecitabine after chemo for metastatic breast cancer
This Phase 3 trial compares two medicines—fulvestrant versus capecitabine—as “maintenance” treatment after your first chemo helps control metastatic breast cancer. It aims to see which one helps people live longer with better disease control.
Guangzhou, GuangdongAges 18–75 - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT05627960RecruitingPhase 1
Testing an antibody drug for advanced solid cancers
This Phase 1 study tests AG01, an antibody that targets a cancer protein called GP88, in people with advanced solid tumors. The goal is to find safe doses and learn whether it can help certain cancers.
Baltimore, MarylandAges 18 years+ - NCT05753657RecruitingEarly Phase 1
Testing insulin and blood sugar monitoring with pioglitazone
This early study tests whether adding pioglitazone, along with close blood-sugar (glucose/insulin) monitoring, can help control high insulin and high blood sugar in people starting alpelisib for metastatic breast cancer. It may help reduce blood-sugar side effects from alpelisib.
HaifaAges 18–85 - NCT05762900RecruitingPhase 2
Shorter breast radiation after surgery for low-risk breast cancer
This Phase 2 trial tests a shorter, focused radiation treatment after breast surgery, either alone or with an extra targeted boost. It’s for people with low-risk breast cancer and no spread to distant organs, aiming to keep results while reducing treatment time and side effects.
BeijingAges 35 years+ - NCT06073418Recruiting
Diet, nutrition, and physical activity in early breast cancer
This study looks at the eating habits, nutrition knowledge, and physical activity of women with early-stage breast cancer. It aims to understand how these factors relate to your health and recovery after surgery.
Aviano, PordononeAges 18 years+ - NCT04134780Recruiting
Ultrasound tests to spot early breast cancer treatment response
This study uses special ultrasound imaging (and may use MRI results) to look for early signs of how locally advanced breast cancer responds to chemotherapy, with or without radiation. If the imaging changes early, it could help doctors adjust treatment sooner.
Houston, TexasAges 18 years+ - NCT06169072RecruitingPhase 2
Finding lymph nodes with a tiny dose of magnetic tracer in breast cancer
This trial is testing whether a very small amount of a magnetic tracer called Magtrace can help find lymph nodes that need to be checked for cancer spread during breast cancer surgery.
GothenburgAges 18 years+ - NCT05505357Recruiting
Skip breast surgery after excellent MRI response
This trial tests whether some women with HER2-positive breast cancer can safely avoid breast surgery if their tumor nearly disappears after chemotherapy. It uses MRI and biopsy results to find people most likely to have no remaining cancer (pCR).
SeoulAges 20 years+ - NCT06282796Recruiting
Early heart risk monitoring for breast cancer chemo
This study tests a method to predict and warn about heart damage from a common type of breast cancer chemotherapy. If you have HER2-positive breast cancer and will receive anthracycline drugs, this trial may help monitor your heart health.
Fuzhou, FujianAges 18–80 - NCT06341894RecruitingPhase 2
Dalpiciclib and hormone therapy for early breast cancer
This trial tests a new pill (dalpiciclib) combined with hormone therapy for women with early-stage, hormone receptor positive/HER2-negative breast cancer. The goal is to see if this combination can lower the chance of cancer coming back after surgery.
Nanjing, JiangsuAges 18–75 - NCT06404697RecruitingPhase 2
Extra radiation to lymph nodes above collarbone for high-risk breast cancer
This trial tests giving a focused, higher dose of radiation to the lymph nodes above the collarbone after breast cancer treatment. It is for patients whose cancer did not fully disappear from those nodes after pre-surgery chemotherapy, to see if extra radiation can help prevent recurrence.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07848243RecruitingPhase 2
A new imaging test to find returning cancer
This trial tests a new imaging agent that helps find cancer cells that have come back. It is given as an injection and then a scan is done to see if it helps doctors locate the cancer.
BeijingAges 18 years+ - NCT07817082RecruitingPhase 2
A new drug for her2 ultra-low advanced breast cancer
This study tests a new targeted drug (SHR-A1811) for breast cancer that has very low HER2 levels. The drug is designed to attack cancer cells with this specific marker, and the study aims to see if it can help slow the cancer's growth.
TianjinAges 18–75 - NCT07757230RecruitingPhase 2
Combination therapy for advanced HR-positive, HER2-low breast cancer
This trial tests a new combination of two targeted medicines for people with a certain type of advanced breast cancer that has grown despite hormone therapy. The medicines may help shrink tumors and slow the cancer's growth.
