Los Angeles, CaliforniaAges 18 years+ - NCT05379153RecruitingPhase 3
Laser therapy for vaginal dryness in breast cancer survivors
This trial tests whether laser therapy can help women who have had breast cancer and now experience vaginal dryness. It aims to see if this treatment can reduce dryness and improve comfort.
Ann Arbor, MichiganAges 22 years+ - NCT07706556Recruiting
Remote activity program for breast cancer survivors
This trial tests a new program to help breast cancer survivors become more active. The program is delivered remotely using a smartphone app, and it adjusts based on your progress. It may be a good fit if you finished treatment less than 5 years ago and are not very active yet.
Lebanon, New HampshireAges 18 years+ - NCT06086704RecruitingPhase 2
PET/MRI scan for PR-positive breast cancer before surgery
This trial tests a new PET/MRI scan (using a special tracer called 18F-FFNP) to see how it images progesterone-receptor-positive breast cancer before surgery. You would get the scan and then have your planned surgery.
Madison, WisconsinAges 18 years+ - NCT06460298RecruitingPhase 1/Phase 2
ProAgio and gemcitabine for triple-negative breast cancer that has spread
This trial tests a new drug called ProAgio combined with the chemotherapy gemcitabine for people with triple-negative breast cancer that has spread to other parts of the body. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Atlanta, GeorgiaAges 18 years+ - NCT07690852Recruiting
Environmental exposures and breast cancer risk study
This study looks at how environmental exposures might affect breast cancer risk. It includes women at average risk, high risk, or those diagnosed with breast cancer before age 50, as well as healthcare providers.
Duarte, CaliforniaAges 18 years+ - NCT07545122RecruitingPhase 1
Testing CT-202 for Triple Negative Breast, Colorectal, and Bladder Cancers
This early-stage trial tests a new antibody drug called CT-202 in patients whose cancer has come back after standard treatments. The drug is designed to target cancer cells that have a specific protein called Nectin-4, and may help the immune system fight the cancer.
Wahroonga, New South WalesAges 18 years+ - NCT07179809Recruiting
Lifestyle program for women with metastatic breast cancer
This trial tests a group-based lifestyle program for women with HR+/HER2- metastatic breast cancer. The program helps you improve diet, increase physical activity, and learn mind-body practices in a supportive group setting.

Sac-TMT alone or with pembrolizumab for advanced triple-negative breast cancer
This trial tests a new drug, Sac-TMT, given alone or with an immunotherapy drug (pembrolizumab) for people with advanced triple-negative breast cancer who have not yet received any treatment for advanced disease. The goal is to see if this combination can shrink tumors or slow the cancer's growth.

- How do I know if I qualify for a breast 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 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.
