Recruiting studies
- NCT05535413RecruitingPhase 1/Phase 2
UTD1 plus capecitabine for HER2-negative breast cancer brain mets
This trial tests whether adding a study drug called UTD1 to capecitabine can shrink or control breast cancer that has spread to the brain. It’s for people with HER2-negative metastatic breast cancer who have brain metastases and meet specific safety and lab requirements.

This trial compares a shorter, more concentrated radiation schedule versus a standard shorter schedule after breast-conserving surgery. It looks at whether the treatment works well and is safe, especially for women whose lymph nodes also need radiation.
São Paulo, São PauloAges 18 years+ - NCT05885009Recruiting
Liquid biopsy test to guide treatment in metastatic prostate cancer
This study looks at using a simple blood test (liquid biopsy) to read tumor DNA and understand how it could affect treatment decisions. It is for adults with metastatic prostate cancer who are about to start, are receiving, or recently finished treatment.
BarcelonaAges 18 years+ - NCT04923542RecruitingPhase 1/Phase 2
Targeted drug plus focused brain radiation for breast cancer
This study tests whether abemaciclib (a targeted pill) given with focused radiation to brain tumors can control hormone receptor–positive, HER2-negative breast cancer in the brain. It’s designed to see if the combination helps shrink or slow the growth of brain metastases while keeping side effects manageable.
Tampa, FloridaAges 18 years+ - NCT05322460Recruiting

Cirtuvivint and Olaparib for BRCA-related ovarian cancer
This trial tests a combination of two targeted drugs, cirtuvivint and olaparib, for a specific type of ovarian cancer that no longer responds to platinum chemotherapy. It may be an option if you have a BRCA mutation or HRD-positive tumor and have already tried a PARP inhibitor.
Aurora, ColoradoAges 18 years+ - NCT06028022RecruitingPhase 2

This trial tests whether a reishi mushroom extract can help reduce fatigue and joint or muscle pain in people with breast cancer who are taking aromatase inhibitors. If you have these symptoms, you may be able to join.
Albert Lea, MinnesotaAges 18 years+ - NCT07553572Recruiting
Smartphone app to track cancer symptoms during treatment
This study tests a smartphone application designed to help you monitor and manage side effects and symptoms while you're receiving chemotherapy or other systemic treatment for breast cancer, colorectal cancer, or lymphoma. The app may help your doctors catch problems early and support you throughout your treatment.
Boston, MassachusettsAges 18 years+ - NCT06915857RecruitingPhase 3
Betamethasone cream vs moisturizer for radiation rash in large-breasted women
This trial tests whether a betamethasone steroid cream works better than regular moisturizer to prevent skin reactions from radiation therapy. It is for women with large breasts who are getting radiation lying face down after breast-conserving surgery.
Toronto, OntarioAges 18 years+ - NCT06925984Recruiting
Targeted radiation for breast cancer that has spread and is growing a little
This trial tests whether giving focused, high-dose radiation to spots where the cancer is growing can help control the disease while you stay on your current hormone therapy and/or CDK4/6 inhibitor. It is for people with ER+/HER2- breast cancer that has spread to a few places and is slowly starting to progress.
BrusselsAges 18 years+ - NCT03758976Recruiting
Study of scans in advanced breast cancer recurrence
This study looks at people with advanced breast cancer to better understand recurrence by using information from recent scans. It may help researchers improve how advanced disease is assessed and followed over time.
LundAges 18 years+ - NCT07171658Recruiting
Cervical cancer screening for women getting breast cancer letters
This trial tests if inviting women for cervical cancer screening along with their breast cancer screening letters helps more people get tested. You might be eligible if you haven't had a cervical cancer screening in the last three years.
Geneva, Canton of GenevaAges 50–74 - NCT05774678RecruitingPhase 3
Pre-surgery radiation options for invasive breast cancer
This trial compares two schedules of radiation given before mastectomy to see which works better for invasive breast cancer, followed by immediate breast reconstruction. It also studies tiny “biomarker” signals in tissue to learn why one radiation approach may help more.
Houston, TexasAges 18 years+ - NCT04476485Recruiting
Predicting breast cancer recurrence after extended hormone therapy
This trial looks at factors that may predict whether hormone receptor–positive breast cancer will come back after you’ve already completed 5 years of hormone (endocrine) therapy. It may help identify who benefits most from longer treatment and follow-up.
Harbin, HeilongjiangAges 18–70 - NCT05856383Recruiting
HER2-positive metastatic breast cancer drug combination study
This trial tests whether inetetamab combined with pyrotinib and vinorelbine works better and is safe for adults with HER2-positive advanced breast cancer. You may be considered if standard options have not removed the cancer with surgery and your body can handle chemotherapy and HER2-targeting medicines.
Hangzhou, ZhejiangAges 18 years+ - NCT07764796Recruiting

Sentinel node biopsy after chemo for initial node-positive breast cancer
This trial checks whether a less invasive sentinel lymph node biopsy (removing just a few nodes) can safely replace full lymph node removal for people whose breast cancer and underarm lymph nodes responded well to chemotherapy. It is for patients who initially had 1 to 3 involved nodes and now appear cancer-free in the armpit.

Circulating tumor DNA guided extra treatment for early triple-negative breast cancer
This trial tests whether using a blood test to detect leftover cancer DNA after initial treatment can help doctors decide if extra therapy is needed for people with early triple-negative breast cancer. It aims to improve outcomes for those with remaining disease after neoadjuvant therapy.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 recruiting breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
