- NCT05645536Enrolling by invitationPhase 3
Safety follow-up for hormone-positive, HER2-negative breast cancer
This trial studies the safety of continuing endocrine therapy with ovarian suppression (for women) after you finish the earlier OVELIA study. It may help doctors confirm that the treatment remains safe for longer-term use.
Greenbrae, CaliforniaAges 18–51 - 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+ - NCT05601440RecruitingPhase 2
Trial for metastatic breast cancer that resisted CDK4/6 treatment
This Phase 2 study tests treatments guided by blood testing (“liquid biopsy”) in people with hormone receptor–positive, HER2-negative metastatic breast cancer that has progressed after standard CDK4/6 medicine plus hormone therapy. It aims to find a better way to control cancer after the first treatment stops working.
Calgary, AlbertaAges Any age - 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+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Birmingham, AlabamaAges Any age - NCT05582499RecruitingPhase 2
Neoadjuvant treatment study for certain breast cancers

SDX-7320 plus eribulin for metastatic triple-negative breast cancer
This Phase 2 study tests whether adding SDX-7320 to eribulin can work better for people with triple-negative metastatic breast cancer. It focuses on patients who have had prior chemotherapy and who also show signs of metabolic imbalance such as higher body weight or higher HbA1c.
Miami, FloridaAges 18 years+ - NCT05573126RecruitingPhase 1/Phase 2
Study of EP0062 for advanced breast cancer with AR+ and ER+
This Phase 1/2 study tests EP0062, a study medicine given alone or with other treatments, in people with advanced or metastatic breast cancer. It’s designed to see how well it works and what side effects it causes when the cancer has specific hormone-receptor markers (AR+ and ER+) and is HER2-negative.
New Haven, ConnecticutAges 18 years+ - NCT05573893Recruiting
Real-world study of trastuzumab deruxtecan for HER2 breast cancer
This study looks at how people feel (patient-reported outcomes) and their real-world health data while they receive trastuzumab deruxtecan for advanced HER2-positive, HER2-low, or HER2-ultralow breast cancer. It helps researchers understand what outcomes happen outside of tightly controlled clinical trials.
AmbergAges 18–130 - NCT05579366RecruitingPhase 1/Phase 2
Study of rinatabart sesutecan for advanced solid tumors
This trial tests an investigational drug called rinatabart sesutecan (also known as Rina-S) for people with advanced solid tumors, including ovarian, endometrial, lung, breast, and other cancers. The drug is designed to target and kill cancer cells, and the study aims to see if it is safe and effective.
Phoenix, ArizonaAges 18 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 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.
Tampa, FloridaAges 18 years+ - NCT05534438RecruitingPhase 2
Tested targeted radiation plus usual drug treatment in metastatic breast cancer
This Phase 2 study tests whether adding a very focused type of radiation to standard drug treatment can better control metastatic breast cancer. It is for people whose cancer is only progressing in one spot, seen on a PET scan.
Basking Ridge, New JerseyAges 18 years+ - NCT05524584RecruitingPhase 2
Anastrozole, fulvestrant, and abemaciclib for hormone-positive breast cancer
This trial tests whether combining three medicines can better control hormone-receptor–positive, HER2-negative metastatic breast cancer that cannot be cured with surgery or radiation. It may help shrink tumors and slow disease growth compared with standard hormone therapy approaches.
Orange, CaliforniaAges 18 years+ - NCT05512364RecruitingPhase 3
Elacestrant for ER-positive, HER2-negative breast cancer with ctDNA relapse
This trial tests whether elacestrant can help stop or delay breast cancer coming back in people whose blood test shows “ctDNA relapse” after early breast cancer treatment. It’s meant for hormone receptor–positive, HER2-negative breast cancer patients who are already taking hormone (endocrine) therapy and have no visible spread on scans.
AnderlechtAges 18 years+ - NCT04563507RecruitingPhase 2
Immunotherapy plus hormone therapy for metastatic ER-positive breast cancer
This Phase 2 study tests a combination of immune-based treatments along with hormone (endocrine) therapy to slow or shrink advanced, hormone-receptor positive, HER2-negative breast cancer. You may be a candidate if your cancer has progressed after standard hormone-blocking medicines and you can start treatment with CDK4/6 medicine plus an aromatase inhibitor.
New York, New YorkAges 18–90 - NCT05461768RecruitingPhase 1
BL-M07D1 for HER2-positive or HER2-low breast cancer
This Phase 1 study tests BL-M07D1, a new investigational medicine, in people with HER2-positive or HER2-low breast cancer (and other solid tumors) that can’t be operated on or has spread. It aims to find a safe dose and learn how well the treatment may work based on HER2 levels in tumor tissue.
Fuzhou, FujianAges 18–75 - NCT05467891RecruitingPhase 2
Ribociclib plus hormone therapy for recurrent breast cancer
This trial tests whether adding ribociclib (a targeted pill) to hormone therapy can control breast cancer that has come back in the breast area or nearby lymph nodes/chest wall. It targets hormone-receptor–positive and HER2-negative tumors to help slow disease after local treatment.
Birmingham, AlabamaAges 18 years+ - NCT05464810RecruitingEarly Phase 1
Letrozole with or without a cholesterol drug for early breast cancer
This early-phase study tests whether adding simvastatin to letrozole can improve outcomes in people with stage I–III breast cancer that grows with hormone signals (hormone receptor positive) and does not have HER2. It looks mainly at whether the approach is safe and useful for this specific breast cancer type.
Atlanta, GeorgiaAges 18 years+ - NCT05422794RecruitingPhase 1
Adding a new drug plus pembrolizumab to standard chemo for TNBC
This trial studies whether adding a new anti-cancer drug (ZEN-3694) and the immunotherapy drug pembrolizumab to standard chemotherapy (nab-paclitaxel) can work better for advanced triple-negative breast cancer. It’s testing safety first (Phase 1) and, for some patients, how well the treatment controls the cancer.
Boston, MassachusettsAges 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+ - NCT05377047RecruitingPhase 3
High-precision radiation for limited breast cancer spread
This trial tests a high-precision radiation therapy (called stereotactic ablative radiotherapy) to treat breast cancer that has spread to a limited number of spots in the body. It aims to control the cancer and improve outcomes, and you can join while on your first-line systemic treatment if the cancer is stable.
