Recruiting studies
- NCT02338167Recruiting
Study for pregnant women with breast cancer
This study is for adults with breast cancer who are pregnant and are either newly diagnosed (early) or have locally advanced or metastatic disease. It aims to better understand how breast cancer treatment should be managed during pregnancy.
Böblingen, Baden-WurttembergAges 18–99 - NCT02830724RecruitingPhase 1/Phase 2
CAR T therapy using blood immune cells for CD70 cancers
This trial tests a personalized immune-cell treatment (CAR T) built from your own blood lymphocytes. It targets cancers that show a marker called CD70, aiming to slow or stop the cancer when other treatments didn’t work.
Bethesda, MarylandAges 18–72 - NCT02535221RecruitingPhase 3
Hormone treatment vs chemotherapy before breast surgery
This Phase 3 trial compares hormone-based treatment versus chemotherapy given before surgery in people who are premenopausal and have hormone-receptor positive, HER2-negative breast cancer. It looks to see which approach works better to control the cancer before the breast operation.
BeijingAges 35–55 - NCT02819882Recruiting
Registry study for advanced or metastatic breast cancer
This study collects health and treatment information from people with breast cancer that cannot be fully removed by surgery or that has spread to other parts of the body. It may help researchers better understand which treatments are used and how people do over time.
Elche, AlicanteAges 18 years+ - NCT02926690RecruitingPhase 1
MELK inhibitor safety study for advanced breast cancer
This Phase 1 study tests how safe a drug called an MELK inhibitor is in people with advanced breast cancer that has spread or cannot be removed with surgery. If you qualify, the study is focused on side effects and includes a special group for triple-negative breast cancer.
Norwalk, ConnecticutAges 18 years+ - NCT02945579Recruiting
Testing skipping breast surgery or radiation for top responders
This trial studies whether some people with early-stage breast cancer who respond extremely well to hormone/chemo/targeted treatment can safely skip breast surgery and/or radiation. It aims to reduce side effects without increasing cancer risk in carefully selected patients.
Gilbert, ArizonaAges 30 years+ - NCT07676461Recruiting
Microbiome study in advanced cancer patients starting immunotherapy
This study looks at the bacteria in your mouth, gut, and tumors to see if they affect how well first-line immunotherapy works. It is for people with advanced stomach, colorectal, breast, cervical, or head-and-neck cancer.
Bogotá, Bogota D.C.Ages 18 years+ - NCT07527689Recruiting
Faster vs. Standard Radiation After Breast Cancer Surgery
This study compares two radiation schedules for breast cancer patients at high risk of cancer returning in lymph nodes. Both use modern radiation therapy, but one delivers treatment faster (ultra-hypofractionated) while the other uses a more moderate schedule. The goal is to see which approach works better with fewer side effects.
ShanghaiAges 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+ - NCT07401537RecruitingPhase 2
Comparing two schedules of immunotherapy for advanced triple-negative breast cancer
This trial tests whether giving immunotherapy less often (extended dose intervals) works as well as the standard schedule for people with advanced triple-negative breast cancer who have already completed 6 cycles of first-line treatment. It aims to see if a longer break between doses can be just as effective with fewer hospital visits.
Guangzhou, GuangdongAges 18–70 - NCT07405931Recruiting
Managing chemo side effects with phone calls and a smartphone app
This study tests whether checking in by phone or smartphone app can help manage chemotherapy side effects. If you are starting a new chemo for stomach, lung, breast, or colon cancer, this program may support you from home.
BusanAges 19 years+ - NCT07415499Recruiting
Breast density impact on mammography screening
This study looks at how breast density affects the ability of mammograms to find breast cancer. It involves women who had a mammogram through a specific screening program.
Verduno, Italy/CNAges 45–75 - NCT07425002Recruiting
Precision Oncology Study in Breast Cancer (PRISM)
This study looks at tumor tissue from people with breast cancer, including those with brain metastases. It aims to learn more about the genetic changes in the cancer to help guide future treatments.
Dublin, LeinsterAges 18 years+ - NCT07426913Recruiting
Virtual reality heart health for breast cancer survivors
This trial tests if a virtual reality program can help breast cancer survivors taking certain chemotherapies improve their heart health. It's for people currently receiving trastuzumab or anthracycline-based treatment, along with immunotherapy, for their first breast cancer diagnosis.
Richmond, VirginiaAges 18 years+ - NCT07441889RecruitingPhase 1/Phase 2
HER2-targeting immune cells for metastatic breast and prostate cancer
This trial tests a new treatment using specially designed immune cells that target HER2, a protein found on some cancer cells. It is for people with metastatic breast or prostate cancer that has worsened after prior treatments.
Charlottesville, VirginiaAges 18 years+ - NCT07443579Recruiting
Mammogram order study for breast cancer survivors
This trial tests if changing the order of mammogram views makes the exam more comfortable for women who have had breast cancer surgery and radiation. You may be able to join if you are due for your first check-up mammogram after finishing treatment.
Beaumont, DublinAges 18 years+ - NCT07443943RecruitingPhase 2
Potato starch supplement for joint pain from hormone therapy
This trial studies whether a dietary supplement made from resistant potato starch can help reduce joint and muscle pain in people who are about to start aromatase inhibitor therapy for breast cancer or high risk. You take the supplement daily and report how you feel over 24 weeks.
Ann Arbor, MichiganAges Any age - NCT07447414Recruiting
Freezing small hormone-driven breast cancers
This study tests cryoablation (freezing) to treat small, early stage breast cancers that are hormone receptor positive and HER2 negative. It may be an option for postmenopausal women who want to avoid surgery.
Lugo, LugoAges Any age - NCT07447700Recruiting
Massage therapy during radiation for breast cancer
This study tests if focused chair massages after each radiation treatment can help with pain, movement, and quality of life for breast cancer patients. You would receive massages during your radiation treatment period.
Columbus, OhioAges 18 years+ - NCT07455188Recruiting
Switching targeted therapies for advanced HER2-positive breast cancer
This trial tests whether switching between two targeted therapy combinations can help women with HER2-positive advanced breast cancer that has progressed after previous treatments. It aims to find a new effective option for people who have already tried one or two lines of therapy.
Zhejiang, HangzhouAges 18 years+ - NCT07459673RecruitingPhase 2
HER2-positive breast cancer trial using ctDNA to guide treatment
This trial tests a personalized treatment plan for HER2-positive breast cancer that has spread. It uses a blood test to track cancer DNA and adjust therapy, including treatments that may help prevent cancer from reaching the brain. The goal is to achieve long-term remission.
Basking Ridge, New JerseyAges 18 years+ - NCT07467824Recruiting
Exercise and support before and after breast cancer treatment
This trial tests whether a program of supervised exercise and full follow-up before and after breast cancer treatment can improve recovery and quality of life for women with early-stage breast cancer.
Valladolid, ValladolidAges 18–65 - NCT07474090Recruiting
