Recruiting studies
- NCT06860529RecruitingPhase 2
Immunotherapy plus chemo for early-stage HR+/HER2- breast cancer
This trial tests adding the immunotherapy drug serplulimab to standard chemotherapy for people with early-stage HR-positive, HER2-negative breast cancer. It aims to see if this combination can improve outcomes before surgery.
Zhengzhou, HenanAges 18 years+ - NCT06858449Recruiting
Exercise and protein during chemo for breast cancer
This study tests whether adding resistance training (like lifting weights) along with a protein shake after workouts can help women with breast cancer maintain muscle and bone health while they receive chemotherapy before surgery.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
Boca Raton, FloridaAges 40 years+ - NCT06860815RecruitingPhase 2
Cemiplimab with liver radiation for breast cancer that spread to the liver
This trial tests a combination of a drug called cemiplimab (an immunotherapy that helps your immune system fight cancer) and a type of targeted radiation (Y-90 SIR-Spheres) given directly to liver tumors. It is for people with breast cancer that has spread to the liver and who have already had at least one type of chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT05233891Recruiting
Swedish-language study of scales used in breast reconstruction
This study checks whether certain rating tools (called “scales”) are working well for people having breast reconstructive surgery at Sahlgrenska University Hospital. It may help future patients because it improves how outcomes and symptoms are measured in the clinic.
GothenburgAges 18–100 - NCT06855654Recruiting
Building resilience in women with breast cancer
This study tests a counseling program designed to help women with metastatic breast cancer build resilience and cope better. If you've been diagnosed within the last 6 months and get your cancer care at UNC, you may be eligible.
Birmingham, AlabamaAges 18 years+ - NCT05396612Recruiting
Studying the immune response in non-cancer-spread breast surgery
This study looks at how your immune system changes while you receive standard breast cancer treatment around the time of surgery. The goal is to learn why some people respond better than others, which could help future treatment choices.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05722795Recruiting
Imatinib to change triple-negative breast cancer to ER-positive
This trial studies whether imatinib (a pill medicine) can “convert” triple-negative breast cancer into an ER-positive type, which may change how the cancer behaves. If the conversion happens, it could open the door to more treatment options in the future.
GothenburgAges 18 years+ - NCT06843083Enrolling by invitation
Which advanced breast scan is better for you?
This study compares two advanced breast imaging methods—contrast-enhanced mammography (CEM) and breast MRI—to see which is better at finding cancer, especially in women with dense breasts or unclear mammogram results. If you are being referred for one of these exams, you may be able to join and help doctors learn which test works best.
NaplesAges 18 years+ - NCT06843096Enrolling by invitation
Special mammogram for finding breast cancer when origin is unknown
This trial uses a special mammogram with contrast dye to look for breast cancer in people who have cancer that started somewhere unknown (called Cancer of Unknown Primary). It may help find if the breast is the source, which could guide treatment.
RomeAges 18 years+ - NCT06833502RecruitingPhase 2
Screening for breast cancer spread after chemo and surgery
This trial aims to find out if doing special scans to check for breast cancer spread to organs (not just lymph nodes) is helpful in certain patients. The study looks at people with breast cancer that had already spread to lymph nodes and did not completely go away with chemotherapy and surgery.
Tampa, FloridaAges 18 years+ - NCT06828588RecruitingEarly Phase 1
A new imaging test for people on HER2 cancer therapy
This study tests a new imaging drug called [68Ga]Ga-ABY-025 to see how well it shows HER2-positive tumors in people who are about to start or have just started HER2-targeted cancer therapy. It may help doctors see if the treatment is working.
Nashville, TennesseeAges 18 years+ - NCT06834204Enrolling by invitation
Better care coordination for cancer survivors
This study tests a program to improve communication between your cancer team and your regular doctor. If you have heart or diabetes risks and you're being treated for breast, prostate, bladder, or endometrial cancer, this trial may help coordinate your care.
New Brunswick, New JerseyAges 18 years+ - NCT06817954Recruiting
Breast reconstruction after mastectomy for breast cancer
This trial tests how safe and effective it is to remove the breast (mastectomy) and rebuild it right away during the same surgery. It is for women with early-stage breast cancer who want reconstruction instead of breast-sparing surgery.
Nanjing, JiangsuAges 18–75 - NCT06807502Recruiting
Blood test for breast cancer follow-up
This trial uses a simple blood test (ScreenCell device) to look for circulating tumor cells (CTCs) in women. It aims to see if CTCs help monitor breast cancer during follow-up, including for those with metastatic or newly diagnosed breast cancer, as well as healthy volunteers.
Neuilly-sur-SeineAges 18 years+ - NCT06807749Recruiting
Adjuvant treatment for premenopausal breast cancer
This trial looks back at premenopausal women with early-stage, hormone-positive, HER2-negative breast cancer who had surgery and an Oncotype DX test, to see how different treatments affected their outcomes. If you fit this group, your past medical records could help researchers learn more about the best treatments.
Roma, Antonella PalazzoAges Up to 60 years - NCT06806930RecruitingPhase 2
Predicting response to hormone therapy before breast cancer surgery
This trial tests whether we can predict how well hormone therapy works before surgery for early-stage breast cancer. It may help women with estrogen receptor-positive, HER2-negative or HER2-low breast cancer avoid or tailor treatments.
Washington D.C., District of ColumbiaAges 21 years+ - NCT06797635RecruitingPhase 2
Study of Patritumab Deruxtecan and Pembrolizumab for High-Risk Early Breast Cancer
This trial tests a combination of targeted therapies (patritumab deruxtecan plus pembrolizumab) along with other anticancer drugs for people with a high-risk type of early-stage breast cancer that is either triple-negative or has very low hormone receptors and is HER2-negative. The goal is to see if this approach can help prevent the cancer from coming back.
Santa Monica, CaliforniaAges 18 years+ - NCT06799065RecruitingPhase 1/Phase 2
Oral drug for advanced solid tumors including ovarian cancer
This trial tests a new daily pill that targets a protein helping cancer cells divide. It may stop tumors from growing in people with advanced or metastatic cancer that has returned or stopped responding to standard treatments, including some types of ovarian, lung, and other solid tumors.
Aurora, ColoradoAges 18 years+ - NCT06802757RecruitingPhase 2
Study of posaconazole with immunotherapy and chemo for triple-negative breast cancer
This trial tests if adding posaconazole (an antifungal drug) to standard immunotherapy and chemotherapy before breast cancer surgery works better than just the standard treatment. It is for people with newly diagnosed, early-stage triple-negative breast cancer.
Jinan, ShandongAges 18–70 - NCT06802172Recruiting
Timing meals during cancer treatment for Alaska Native patients
This study tests whether scheduling meals at specific times of day can improve how patients feel during cancer treatment. It is for Alaska Native or American Indian people with certain cancers (rectal, HER2+ or triple negative breast, or other solid tumors) who are receiving neoadjuvant (before surgery) or adjuvant (after surgery) therapy.
Anchorage, AlaskaAges 21 years+ - NCT06793306Enrolling by invitation
Breast cancer study comparing younger and older patients
This trial looks at differences between younger and older breast cancer patients to better understand the disease. If you had breast cancer between the ages of 18 and 75 and were treated in a Chinese hospital from 2000 to 2024, you might be able to help.
BeijingAges 18–75 - NCT06790693RecruitingPhase 3
Inavolisib plus hormone therapy for advanced breast cancer
This trial tests a new targeted therapy, inavolisib, combined with standard hormone therapy and a CDK4/6 inhibitor for people with a specific genetic mutation (PIK3CA) in their hormone receptor-positive, HER2-negative advanced breast cancer that has not been treated before. It compares this combination to a placebo plus the same standard treatments.
Goodyear, ArizonaAges 18 years+ - NCT06787339RecruitingPhase 2
Capecitabine for low-risk triple negative breast cancer
