Vacuum dressing to prevent wound problems after breast cancer surgery
This study tests a special vacuum dressing (negative pressure therapy) to prevent wound problems after complex breast cancer surgery. It's for women who have risk factors for poor healing and are having a mastectomy with immediate reconstruction or a certain breast-conserving surgery.
Dijon, Côte d'OrAges 18 years+ - NCT06263543RecruitingPhase 2
Sequencing antibody-drug conjugates in ER+, HER2-low breast cancer
This trial tests different sequences of antibody-drug conjugates (a type of targeted chemotherapy) for people with ER-positive, HER2-low or ultra-low metastatic breast cancer that has stopped responding to hormone therapy and has progressed on Enhertu. You must have had 1–4 prior chemotherapies for metastatic disease.
Miami, FloridaAges 18 years+ - NCT05259410Recruiting
Time-restricted eating during breast cancer chemotherapy
This trial studies whether time-restricted eating (eating only within certain hours) during breast cancer chemotherapy is safe and helpful. Researchers want to see if it improves chemotherapy outcomes and side effects for people with stage I–III breast cancer.
Chicago, IllinoisAges 25–99 - NCT06144164RecruitingPhase 3
Preventing Lymphedema After Breast Cancer Surgery
This trial tests a comprehensive prevention program to reduce lymphedema—a swelling in the arm—after breast cancer surgery that removes lymph nodes. If you qualify, you'll learn special exercises and care steps to lower your risk.
Basking Ridge, New JerseyAges 18–75 - NCT06113016RecruitingPhase 2
Preventing frailty with fisetin and exercise in breast cancer survivors
This study tests whether adding a supplement called fisetin to an exercise program can help prevent frailty in women who have finished chemotherapy for early-stage breast cancer. If you are postmenopausal, have completed chemo within the last year, and can walk a certain distance, you may qualify.
Alhambra, CaliforniaAges Any age - NCT06121453Recruiting
Adherence support for metastatic breast cancer patients
This study tests a program to help people with metastatic breast cancer take their endocrine therapy, CDK4/6 inhibitors, and heart-related medications as prescribed. If you sometimes miss doses of these medicines, you may be able to join.
New York, New YorkAges 18–99 - NCT06127797Recruiting
MRI surveillance study for breast cancer survivors with dense breasts
This study is testing whether adding an MRI to your regular mammogram can help find any new breast cancers earlier. It is for women who have had breast cancer before and still have dense breast tissue, making mammograms harder to read.
Houston, TexasAges 18 years+ - NCT06085742RecruitingPhase 2
CMC chemotherapy for early stage breast cancer
This trial tests a chemotherapy combination (CMC) for people with early-stage, hormone receptor-positive, HER2-negative breast cancer who have a high risk of recurrence. It aims to understand if this oral regimen is effective and tolerable.
Chicago, IllinoisAges 18 years+ - NCT05941520RecruitingPhase 2
Acolbifene vs low-dose tamoxifen to prevent breast cancer
This Phase 2 trial compares acolbifene and low-dose tamoxifen to see which better lowers breast cancer risk in premenopausal women at high risk. You would be followed with health visits, blood tests, and a breast tissue sampling procedure.
Duarte, CaliforniaAges 35 years+ - NCT05837455RecruitingPhase 2
Biomarker-guided treatment for early breast cancer before surgery
This trial looks at whether using tumor test results (biomarkers) can help guide the best hormone treatment and chemotherapy before surgery. It focuses on people with stage II or III, ER-positive, HER2-negative breast cancer, with the goal of improving how well the tumor responds before it is removed.
St Louis, MissouriAges 18 years+ - NCT05660083RecruitingPhase 2
Study of alpelisib plus iNOS inhibitor with nab-paclitaxel
This Phase 2 trial tests whether a combination of medicines can shrink and control HER2-negative metaplastic breast cancer that cannot be removed with surgery (locally advanced) or has spread (metastatic). It may help people whose cancer has specific lab/pathology features, and it also checks safety and how well the treatment works in the body.
Bethesda, MarylandAges 18 years+ - NCT05608252RecruitingPhase 1/Phase 2
Drug combination for advanced ER-positive, HER2-negative breast cancer
This Phase 1/2 study tests how well a new treatment combination (VS-6766, abemaciclib, and fulvestrant) works for metastatic or hard-to-remove breast cancer that is hormone-driven (ER/PR positive) and HER2 negative. It is mainly designed to find the safest dose and then see whether it can control the cancer after it has progressed on certain prior medicines.
Boston, MassachusettsAges 18 years+ - NCT05378204Recruiting
Testing DNA repair marker for PARP inhibitor resistance
This study looks at specific DNA “damage repair” proteins as a marker to understand why some BRCA-mutated breast cancers may resist PARP inhibitor treatment. Your biopsy (or existing biopsy) helps researchers study whether these lab markers relate to how well PARP inhibitors work.
BordeauxAges 18 years+ - NCT05313191Recruiting
Proton therapy for tumors after prior radiation
This study looks at whether a type of proton beam treatment can be given safely and effectively to tumors that have already been treated with radiation before. It may help people whose tumors came back or persisted after earlier radiation, using a specific proton method called pencil beam scanning.
New York, New YorkAges 18 years+ - NCT04891068RecruitingPhase 2
Pre-surgery low-dose azacitidine for high-risk early breast cancer
This trial studies whether giving a low dose of azacitidine before surgery can shrink or control high-risk early breast cancer. It’s meant for adults whose cancer has not yet spread to distant organs.
Chicago, IllinoisAges 18 years+ - NCT04521764RecruitingPhase 1
Vaccine for Metastatic Breast Cancer
This trial tests a vaccine (MV-s-NAP) that is injected directly into a tumor to stimulate your immune system against breast cancer. It is for people with metastatic breast cancer that has spread despite prior treatments.
Rochester, MinnesotaAges 18 years+ - NCT04517838Recruiting
Testing immune responses to anti-HER2 breast cancer treatments
This study looks at how your immune system reacts to anti-HER2 treatments in people with HER2-positive breast cancer. It may help doctors understand who responds best by studying immune signals in blood (and sometimes tissue) during or after treatment.
Jacksonville, FloridaAges 18 years+ - NCT04529044RecruitingPhase 2
177Lu-DOTATATE for advanced breast cancer with targeted receptors
This Phase 2 trial tests whether 177Lu-DOTATATE can slow or shrink stage IV or recurrent breast cancer. It targets tumor “receptors” found on scans, using a radioactive medicine that delivers radiation directly to cancer cells.
Portland, OregonAges 18–100 - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT03941756Recruiting
Lymph bypass before underarm node surgery to prevent swelling
This study looks at whether adding a lymph “bypass” procedure before underarm lymph node surgery can lower the chance of arm or chest swelling (lymphedema) after cancer treatment. It compares people having lymph node surgery for breast cancer with plans for radiation, and a melanoma comparison group.
Houston, TexasAges 18 years+ - NCT03936478RecruitingPhase 2
MRI-guided partial breast radiation in three short treatments
This study tests a faster, targeted type of radiation for early breast cancer, using real-time MRI to help plan and guide treatment. It may help deliver the same cancer-fighting effect while limiting radiation to the rest of the breast.
Madison, WisconsinAges 40 years+ - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
