Birmingham, AlabamaAges 18 years+ - NCT04360941RecruitingPhase 1
Test drug combo for metastatic breast cancer with AR-positive type
This Phase 1 trial tests palbociclib (a pill) plus avelumab (an IV antibody) for people with metastatic or hard-to-remove locally advanced breast cancer that is AR-positive but otherwise triple-negative. The goal is to see if the treatment is safe and potentially effective for this specific cancer subtype.
Manchester, Greater ManchesterAges 18 years+ - NCT07541079RecruitingPhase 3
Testing a New Breast Cancer Drug for Women Who Can't Tolerate Current Therapy
This study tests giredestrant, a new hormone-blocking medication, in postmenopausal women with early-stage ER+ breast cancer who have experienced intolerable side effects from their current aromatase inhibitor therapy. The trial will measure how well you tolerate this new drug and how it affects your quality of life.
Fountain Valley, CaliforniaAges 18 years+ - NCT05592938Recruiting
Partial breast re-irradiation for cancer recurrence
This trial tests a shorter course of radiation to only the part of the breast where cancer has come back. It's for women who had radiation years ago and now have a small new or recurrent tumor that can be removed by surgery.
New York, New YorkAges 18–99 - NCT07661927RecruitingPhase 2
Skipping hormone therapy for low-risk breast cancer
This trial tests whether women with very low-risk, early-stage breast cancer can safely skip hormone therapy after surgery. It is designed for women who are 60 or older and whose cancer shows no spread to lymph nodes and has favorable biology.
AngersAges 60 years+ - NCT06640881RecruitingPhase 2
Repeat breast-conserving surgery with partial reirradiation
This trial tests a new approach for women whose breast cancer has returned in the same breast after earlier surgery and radiation. Instead of removing the whole breast, doctors will remove only the tumor again and give a small, focused dose of radiation before surgery, aiming to preserve the breast.
AmsterdamAges 50 years+ - NCT07102381RecruitingPhase 2
Zanidatamab plus chemo before surgery for HER2+ breast cancer
This trial tests a new drug called zanidatamab combined with chemotherapy to shrink HER2-positive breast cancer before surgery. It may help improve treatment outcomes for people with stage 2 or 3 breast cancer that has not spread.
Long Beach, CaliforniaAges 18 years+ - NCT05996107RecruitingPhase 1
Ribociclib with radiation for high-risk HR+ breast cancer
This trial tests whether adding the targeted therapy ribociclib (Kisqali) to radiation after surgery reduces the risk of breast cancer returning in patients with high-risk, hormone-positive breast cancer.
Ann Arbor, MichiganAges 18 years+ - NCT03017573Recruiting
Cancer biobank study linking tumor, immune system, and environment
This study collects tumor and related samples from people with certain newly diagnosed cancers. Researchers use these samples to better understand how cancer cells, the surrounding tissue, and the immune system interact, which may guide better future treatments.
BordeauxAges 18 years+ - NCT03150576RecruitingPhase 2/Phase 3
Before-surgery treatment for triple-negative or BRCA breast cancer
This trial tests an “at-the-source” medicine given before surgery to shrink triple-negative and/or BRCA-related breast cancer. It may help doctors see whether it improves tumor response and reduces cancer spread at surgery time.
Cambridge, CambridgeshireAges 16–70 - 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+ - NCT03591276RecruitingPhase 1/Phase 2
Doxorubicin plus pembrolizumab for hormone-resistant breast cancer
This Phase 1b/2 trial tests a combination of pegylated liposomal doxorubicin and pembrolizumab for breast cancer that no longer responds to hormone treatment. It aims to see how well the combination works and how safely it can be given to patients with advanced disease.
JerusalemAges 18 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+ - 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+ - NCT03729115Recruiting
Breast cancer risk tracking for women at very high risk
This study checks how well a “multi-step” monitoring plan (mostly imaging and follow-up) can track breast cancer risk early in women who are at high risk. You may qualify if you have certain gene changes or strong risk from family history, breast density, or past radiation.
Chicago, IllinoisAges 25 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+ - 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+ - 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+ - 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.
