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+ - 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.
SingaporeAges 18–99 - NCT05042687Recruiting
Compare a breast imaging scan with MRI in high-risk women
This study compares two ways of imaging the breast—molecular breast imaging (a scan that uses a small radioactive tracer) and standard breast MRI—to better find or rule out breast cancer. You may join if you are considered high risk and already have a breast MRI planned, and you can do both tests close together.
Houston, TexasAges 18 years+ - NCT05095207RecruitingPhase 1/Phase 2
Abemaciclib and bicalutamide for HER2-negative metastatic breast cancer
This Phase 1/2 trial tests whether combining abemaciclib with bicalutamide can slow or shrink HER2-negative, androgen receptor–positive (AR-positive) metastatic breast cancer. It mainly looks at safety and side effects, and also whether the combination can help patients with this type of breast cancer.
New York, New YorkAges 18–90 - NCT05115474RecruitingPhase 2
Screening brain MRI study for stage IV breast cancer
This trial checks whether taking screening brain MRI scans in people with stage IV breast cancer helps find brain involvement earlier. It may help guide treatment decisions for those who would otherwise only get brain imaging after symptoms start.
Clearwater, FloridaAges 18 years+ - NCT05222100Recruiting
Study how breast implants affect mammogram screening
This trial looks at whether having breast implants changes what happens during routine breast cancer screening with mammograms. It may help improve how screening is done and understood for people with implants.
GothenburgAges 40–75 - NCT05269381RecruitingPhase 1/Phase 2
Personalized cancer vaccine with pembrolizumab for advanced tumors
This study makes a custom vaccine from your tumor’s genetic information and gives it with pembrolizumab (an immune therapy). It aims to help control advanced solid tumors by teaching your immune system to recognize cancer-specific targets.
Jacksonville, FloridaAges 16 years+ - NCT05386719Recruiting
Cardiometabolic screening for people after early breast cancer
This trial tests a screening program to look for heart- and metabolism-related health risks in people who have completed treatment for early breast cancer. It may help catch problems earlier so you can get timely care.
Baltimore, MarylandAges 18 years+ - NCT05388149RecruitingPhase 2
Neratinib plus Kadcyla to treat leftover HER2 breast cancer
This trial studies whether adding neratinib to Kadcyla (T-DM1) can help eliminate “molecular residual disease,” meaning tiny traces of cancer left after surgery and standard HER2 treatment. It’s for adults with HER2-positive breast cancer who still test positive after a short course of Kadcyla, with no signs of cancer returning or spreading on scans.
Toronto, OntarioAges 18 years+ - NCT05420454RecruitingPhase 4
Neoadjuvant treatment for breast cancer before surgery
This trial tests a treatment given before breast surgery to shrink breast cancer and improve outcomes based on your tumor type. Your eligibility depends on tumor size/stage, hormone and HER2 markers, and overall health checks.
Hangzhou, ZhejiangAges 18 years+ - NCT05420467RecruitingPhase 4
Trial of add-on breast cancer treatment after surgery
This Phase 4 study tests an additional (adjuvant) treatment for breast cancer after surgery and standard follow-up care. It may help lower the chance the cancer comes back, but you must match specific tumor and body-chemistry requirements to join.
Hangzhou, ZhejiangAges 18 years+ - NCT05455619RecruitingPhase 1/Phase 2
Targeted drugs for PI3K-altered, HR+/HER2- breast cancer
This Phase 1/2 trial tests how well a combination of targeted medicines works for advanced or returning HR+/HER2- breast cancer that has a PI3K pathway change (such as PIK3CA, PTEN, or AKT1). It may help by blocking growth signals in the cancer and is especially for people whose cancer has progressed after hormone therapy and a CDK4/6 inhibitor.
Loma Linda, CaliforniaAges 18 years+ - NCT05460975Recruiting
Study of dense breast tissue seen on ultrasound
This study looks at breast cancer risk by analyzing what is seen in dense breast tissue during a screening ultrasound. It may help improve how doctors evaluate risk in people with very dense breasts.
SeoulAges 40–69 - NCT05465031RecruitingPhase 4
Testing heart-protection medicine during breast cancer treatment
This trial tests sacubitril/valsartan to help prevent heart weakness (cardiotoxicity) caused by breast cancer treatments like anthracyclines and/or anti-HER2 drugs. If you qualify, you may be offered this heart-protection medicine while your cancer is treated.
Opole, Opole VoivodeshipAges 18 years+ - NCT05468034Recruiting
Exercise program for metastatic breast cancer using a phone

New Haven, ConnecticutAges 18 years+ - NCT05483491RecruitingPhase 1
TCR cell therapy for select metastatic cancers
This Phase 1 trial tests a personalized immune-cell treatment (TCR-T cells) for certain metastatic cancers. It targets cancers that carry a specific marker and requires patients to have a specific immune-system match, aiming to improve cancer control when standard options were already tried.
New Brunswick, New JerseyAges 18 years+ - NCT05491226RecruitingPhase 2
Pembrolizumab plus radiation and myeloid-targeting for high-risk breast cancer
This trial studies whether adding pembrolizumab (an immune “unlocking” drug) to radiation and another treatment that targets certain immune cells can improve outcomes for women with high-risk, early-stage triple negative breast cancer. You may be considered if your cancer has signs that it may respond less to immunotherapy on its own.
Los Angeles, CaliforniaAges 18 years+ - NCT05504707RecruitingPhase 1
Study drug for early-stage, HER2-negative, low-risk hormone breast cancer
This Phase 1 trial tests a new study drug called DC1 given before standard breast cancer treatments. It focuses on people with HER2-negative breast cancer that is “hormone negative” or “hormone low,” aiming to see if the treatment is safe and whether it may work before surgery or other local therapy.
