This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04698252RecruitingPhase 2
Local treatment for ER/PR-positive limited spread breast cancer
This Phase 2 study tests whether treating a small number of metastatic spots with a local approach (like targeted radiation, surgery, or ablation) can help people with ER/PR-positive breast cancer. It aims to help when the cancer has spread only to a few areas and has not significantly worsened after initial whole-body treatment.
São Paulo, São PauloAges 18 years+ - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04841148RecruitingPhase 2
Avelumab or hydroxychloroquine to target hidden breast cancer
This Phase 2 trial tests whether adding different medicines—either avelumab or hydroxychloroquine, with or without palbociclib—can eliminate dormant “leftover” breast cancer cells. It’s meant for people with hormone-receptor–positive breast cancer who have no visible cancer now, but still have detectable dormant cells in the bone marrow.
Washington D.C., District of ColumbiaAges 18 years+ - NCT04886531RecruitingPhase 2
Pre-surgery neratinib plus hormone therapy with trastuzumab
This study tests whether a pre-surgery treatment plan that adds neratinib to hormone therapy and trastuzumab can shrink HER2-positive, ER-positive breast cancer before surgery. It may help patients by improving how much cancer is eliminated at the time of surgery.
Chicago, IllinoisAges 18 years+ - NCT04916990Recruiting
Care program for rural adults with several lung and head cancers
This study looks at how to improve care for adults with certain cancers who live in rural areas and may face access problems. It mainly focuses on people receiving cancer treatment at specific Colorado-area hospitals, and who are uninsured or underinsured.
Aurora, ColoradoAges 18–99 - NCT07137416RecruitingPhase 1
Testing a new combination of cancer drugs for HER2-positive tumors and breast cancer
This trial tests the safety of combining two drugs, CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd), in people with HER2-positive solid tumors or certain types of breast cancer. If you have advanced cancer that hasn't responded to other treatments, this study may be an option.
Boston, MassachusettsAges 18 years+ - NCT06970912RecruitingPhase 2
ctDNA-Guided Reduced Chemo in HR+/HER2- Breast Cancer
This study is testing whether using a ctDNA blood test can help doctors decide if patients with hormone receptor-positive, HER2-negative breast cancer can safely receive less intensive chemotherapy after surgery. The goal is to reduce side effects while still preventing the cancer from coming back.
Beijing, Beijing MunicipalityAges 18–75 - NCT05142800Recruiting
Screening for Lymphedema in Breast Cancer Targeted Therapy
This study is looking at whether targeted therapy for breast cancer changes the risk of arm swelling (lymphedema). It is a screening trial that uses a machine to measure arm size and check for any swelling early on.
Boston, MassachusettsAges 18–80 - NCT07600164RecruitingPhase 4
Real-world study of pyrotinib treatment for advanced HER2-positive breast cancer
This study follows patients with advanced breast cancer that has a protein called HER2 to see how well pyrotinib (a targeted drug) works when used in routine clinical practice. You'd be tracked over time to understand how this treatment affects your cancer and quality of life.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04965766RecruitingPhase 2
Study drug for HER2-negative, advanced breast cancer after prior treatment
This Phase 2 trial tests patritumab deruxtecan (U3-1402) in people with HER2-negative, hormone-receptor positive (HR+) breast cancer that cannot be removed by surgery or has spread. It’s for cancers that have progressed despite endocrine therapy plus a CDK4/6 inhibitor, aiming to shrink tumors and control the disease.
DijonAges 18 years+ - NCT05020574RecruitingPhase 2
Study how the microbiome may affect breast implant infections
This Phase 2 study looks at whether changes in the body’s “microbiome” (the normal germs in and on the body) are linked to infections after breast surgery with implants. It may help doctors better predict and prevent implant infections in people undergoing mastectomy with immediate implant placement.
San Francisco, CaliforniaAges 18 years+ - NCT05020860RecruitingPhase 2
Study how early breast cancer responds on imaging and under a microscope
This Phase 2 study looks at how well early breast cancer shrinks with treatment and how that matches with what doctors find after surgery under the microscope. The goal is to learn better ways to predict and assess treatment success.
Houston, TexasAges 18 years+ - NCT05029999RecruitingPhase 1
Test drugs for HER2-negative advanced breast cancer
This Phase 1 trial tests a combination of immune-targeting drugs (a CD40 medicine and a substance that helps immune cells act) plus chemotherapy in people with HER2-negative advanced breast cancer that has progressed. It aims to find a safer dose and see whether the treatment can shrink tumors or slow the cancer.
Chicago, IllinoisAges 18–99 - NCT05035745RecruitingPhase 1/Phase 2
Selinexor plus talazoparib for advanced triple-negative breast cancer
This trial tests selinexor plus talazoparib in people with advanced, treatment-resistant solid tumors and, separately, advanced triple-negative breast cancer. It aims to see whether this combination can shrink tumors or slow their growth when standard options have not worked.
