Recruiting studies
- NCT03536897Recruiting
Radiation registry after lumpectomy for certain early breast cancers
This study collects information about people with early-stage, hormone-receptor–positive breast cancer who have a lumpectomy and radiation. It may help doctors understand outcomes after this standard treatment and improve care for future patients.
Columbus, OhioAges 65 years+ - NCT03606967RecruitingPhase 2
Individualized vaccine added to standard treatment for metastatic triple-negative breast cancer
This Phase 2 trial tests whether adding a personalized cancer vaccine to durvalumab (an immunotherapy), tremelimumab (another immunotherapy), and chemotherapy can improve outcomes for people with metastatic triple-negative breast cancer. It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 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 - NCT03671044RecruitingPhase 3
Testing a nano-form of docetaxel for triple-negative breast cancer
This Phase 3 study tests whether a special form of docetaxel (a chemotherapy drug) works better and is safe for people with triple-negative breast cancer that has spread or grown locally. You may be eligible if your cancer is triple-negative and you have measurable disease that can be tracked on scans, along with adequate organ and heart function.
Columbus, GeorgiaAges 18–65 - NCT03694756Recruiting
Testing special MRI to see tiny breast cancer structures
This study is testing whether a special MRI scan can help show tiny features inside breast tumors (TMEM). It’s mainly a “feasibility” study, meaning the team is checking if the scan can be done safely and clearly in different types of operable breast cancer.
The Bronx, New YorkAges 18 years+ - NCT03711110Recruiting
Heart-protection plan for older people with certain cancers
This trial looks at strategies to help prevent heart and blood-vessel problems in people over 65 who have certain cancers. It may help by monitoring and treating heart risks early to lower the chance of future cardiovascular events.
Santiago de Compostela, A CoruñaAges 65 years+ - NCT03730922Recruiting
Delayed vs immediate breast reconstruction after mastectomy and radiation
This study compares two timing options for rebuilding the breast after mastectomy followed by radiation: a reconstruction done later (delayed) versus one done sooner (delayed-immediate). The goal is to see which approach works better and is safer for recovery after treatment.
AabenraaAges 18 years+ - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
Houston, TexasAges 18 years+ - NCT03740893RecruitingPhase 2
Test drug to block DNA damage in triple-negative breast cancer
This Phase 2 trial studies a treatment given around the time of breast surgery to help shrink or control residual (remaining) triple-negative breast cancer. It also checks biomarkers (lab signals) to understand who benefits, with some people receiving anti–PD-L1 immunotherapy and some not.
Bournemouth, DorsetAges 18 years+ - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT03788213Recruiting
Shorter vs longer radiation after breast cancer surgery
This trial compares giving breast radiation over one week versus three weeks after surgery. It aims to see whether the shorter schedule works just as well and is safe for people with certain types of early breast cancer.
Kolkata, West BengalAges 18 years+ - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.
San Carlos, CaliforniaAges 18 years+ - NCT03827317Recruiting
Scan to see HER2 in breast cancer with a new tracer
This study tests a new PET scan tracer to show where HER2-positive breast cancer cells may be in the body. It may help doctors better “map” HER2 activity, including in people with HER2-positive or HER2-negative cancer.
LondonAges 18 years+ - NCT03856372Recruiting
Shorter radiation schedule after mastectomy for high-risk breast cancer
This trial compares a shorter radiation plan to a standard longer plan after mastectomy for people considered high risk. It may help reduce treatment time while still trying to prevent breast-cancer recurrence.
Suzhou, JiangsuAges 18–75 - NCT03870620Recruiting
Register for metastatic breast cancer patients in Austria
This trial is a non-treatment registry that collects information about people with metastatic breast cancer in Austria. It may help researchers better understand the disease and outcomes over time by tracking real-world patient details.
Salzburg, State of SalzburgAges 18 years+ - NCT03897270Recruiting
Breast cancer or healthy women for new breast imaging
This study tests a new way to look at the breast using photoacoustic imaging, alongside a breast MRI. It may help researchers see breast masses more clearly, even though it’s mainly for measuring how well the imaging works.
Buffalo, New YorkAges 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+ - NCT03946202RecruitingPhase 2
Radiation plus an in-tumor drug for breast cancer
This Phase 2 trial tests adding a drug inside the tumor (an “in-tumor” injection) to make radiation work better for locally advanced or recurrent breast cancer. It’s meant to help control the tumor area for better long-term local symptom control.
Trivandrum, KeralaAges 18 years+ - NCT03971045RecruitingPhase 2
Pembrolizumab plus low-dose oral chemo for chest wall breast cancer
This Phase 2 trial tests pembrolizumab (an immune therapy) plus low-dose oral cyclophosphamide in people with chest wall breast cancer that has spread locally and may have distant metastases. It aims to see if this combination can shrink tumors and control cancer longer, especially in tumors with certain immune markers.
MilanAges 18 years+ - NCT03995082Recruiting
Survey study for newly diagnosed breast cancer patients
This study asks newly diagnosed breast cancer patients to fill out a survey about their experiences and symptoms. It may help the care team improve how they measure patient needs and experiences.
Denver, ColoradoAges Any age - NCT07702708Recruiting
AI predicts chemotherapy response in HR+/HER2- breast cancer
This trial uses AI to analyze your pre-treatment MRI and predict how well your tumor will respond to chemotherapy before surgery. It is for people with HR+/HER2- breast cancer who need chemo before their operation.
Fuzhou, FujianAges 18 years+ - NCT07703033Recruiting
