L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT04427293RecruitingPhase 1
Testing lenvatinib and pembrolizumab before breast cancer surgery
This early-phase trial tests whether lenvatinib plus pembrolizumab given before surgery can help treat early-stage triple-negative breast cancer. If you qualify, you would receive study medicines before your planned operation to remove the tumor and nearby lymph nodes.
Chicago, IllinoisAges 18 years+ - NCT04852887RecruitingPhase 3
Testing shorter breast radiation after low-risk hormone breast cancer
This Phase 3 trial studies whether “less intense” radiation can work as well as standard radiation for certain early-stage hormone receptor–positive, HER2-negative breast cancers that have a low Oncotype DX score. It may help reduce treatment burden while keeping cancer control strong.
Birmingham, AlabamaAges 50–70 - NCT06642441Recruiting
Vitamin D for reducing chemotherapy side effects in breast cancer
This trial tests whether taking vitamin D supplements can reduce side effects from chemotherapy in people with breast cancer. It is for patients with low vitamin D levels who are about to start their first chemotherapy treatment.
Xining, QinghaiAges 18–80 - NCT06421285Recruiting
Exercise before breast cancer surgery to prevent lymphedema
This trial tests whether doing exercise before surgery can help prevent arm swelling (lymphedema) in women being treated for breast cancer. If you are newly diagnosed, facing chemotherapy first, and can exercise safely, this study might be a good fit.
Seoul, Seoul Special CityAges 20–80 - NCT07238088Recruiting
Mammogram checkup and guidance for Puerto Rico
This trial helps women aged 40-74 in certain areas of Puerto Rico who are overdue for a mammogram. It offers counseling and resources to get screened for breast cancer.
San JuanAges 40–74 - NCT07189871RecruitingPhase 1/Phase 2
177Lu-BetaBart for advanced solid tumors
This trial tests a new radioactive drug, 177Lu-BetaBart, for people with certain advanced solid tumors that have stopped responding to other treatments. The goal is to see if it can shrink tumors or slow their growth.
Dothan, AlabamaAges 18 years+ - NCT07190066Recruiting
MELIORA: Health data collection for women
This study collects information about health and lifestyle using a smartphone app. It's for women in several European countries who are either healthy but could benefit from more activity, or are currently being treated for breast cancer, or have finished treatment.
AthensAges 18 years+ - NCT07220967RecruitingPhase 4
Antibiotics to prevent infection after breast expander surgery
This trial tests whether placing antibiotic beads near the surgical site during breast reconstruction can help prevent infections. It is for women having a mastectomy followed by immediate breast reconstruction with a tissue expander.
Basking Ridge, New JerseyAges 18 years+ - NCT06435429RecruitingPhase 3
Zanidatamab vs trastuzumab for HER2+ breast cancer
This study compares a new drug called zanidatamab against trastuzumab (Herceptin), both given with a chemotherapy of your doctor's choice. It is for people with HER2-positive breast cancer that has spread and who have already tried T-DXd treatment.
Phoenix, ArizonaAges 18 years+ - NCT06171360Recruiting
Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.
BrusselsAges 18–100 - NCT06503380Recruiting
Managing blood side effects from breast cancer targeted drugs
This study looks at how well current methods manage low blood cell counts (low platelets, low white blood cells, and low red blood cells) that can happen from targeted therapies for breast cancer. If you have breast cancer and are getting or have gotten a targeted therapy, this trial could help improve care for side effects like these.
Shanghai, Not US/CanadaAges Any age - NCT06642428Recruiting
Vitamin D for breast cancer treatment before surgery
This trial tests whether taking vitamin D pills during chemotherapy or targeted therapy (before breast cancer surgery) can improve how well the treatment works and reduce side effects. It is for women with low vitamin D levels.
Xining, QinghaiAges 18–80 - NCT07367269Recruiting
Mandala coloring for anxiety in breast cancer chemo patients

Partial breast radiation vs whole breast radiation after lumpectomy
This trial studies whether treating only part of the breast with radiation works as well as treating the whole breast in people with early breast cancer after lumpectomy. It may help reduce radiation exposure to healthy tissue, while still controlling the cancer.

Beijing, Beijing MunicipalityAges 18 years+ - NCT04874038RecruitingPhase 3
Lidocaine infusions to prevent long-lasting pain after breast surgery
This Phase 3 study tests whether receiving lidocaine through an IV during breast surgery can lower the chance of ongoing pain afterward. If it works, it may help some people avoid chronic, surgery-related pain in the chest wall, shoulder, or arm.
Calgary, AlbertaAges 18–100 - NCT07256119Recruiting
Can a supplement help ease radiation skin burns?
This study tests whether taking an antioxidant called alpha lipoic acid can reduce skin irritation caused by radiation therapy in women with early-stage breast cancer. If you qualify, you would receive the supplement during your radiation treatment to see if it helps protect your skin.
ZagazigAges 18–75 - NCT05116449Recruiting
Supportive care program for women having breast cancer surgery

- Yes. Clin2 currently lists 252 recruiting breast cancer prevention 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 prevention 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 prevention 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.
