PET scan to predict if immunotherapy works in TNBC
This trial tests a new type of PET scan (Granzyme B-PET) to see if it can predict how well immunotherapy will work for people with triple-negative breast cancer that has spread. If it works, doctors might be able to tell sooner whether treatment is helping.
ShanghaiAges 18 years+ - NCT07638774Recruiting
Compression Gloves and Socks to Prevent Nerve Damage from UTD1 Cancer Drug
This study tests whether wearing special compression and cooling gloves and socks can help prevent nerve damage (numbness and tingling in hands and feet) that sometimes occurs in women receiving a breast cancer medication called UTD1. You would wear these gloves and socks during and after your chemotherapy treatment.
ShanghaiAges 18–75 - NCT07586215Recruiting
HER2-PET imaging to predict response to T-DXd in advanced breast cancer
This study is testing whether a special PET scan (HER2-PET) can help predict how well the drug T-DXd (also known as Enhertu) might work for your breast cancer. T-DXd is a targeted therapy that delivers chemotherapy directly to cancer cells with certain markers. The trial will check if the scan can identify which patients are more likely to benefit, which could help personalize treatment.
ShanghaiAges 18 years+ - NCT07369505RecruitingPhase 1
A study of Sapu003 for advanced tumors sensitive to mTOR
This trial tests a new drug, Sapu003, in people with certain advanced cancers that may respond to mTOR-targeted therapy. It is looking at two groups: postmenopausal women with a type of breast cancer (HR+/HER2-), and adults with kidney, liver, neuroendocrine, or TSC-related tumors. The goal is to see if Sapu003 is safe and effective.

Testing trastuzumab deruxtecan in HER2-zero breast cancer
This trial tests a new drug called trastuzumab deruxtecan (a targeted antibody-drug combination) for people with advanced breast cancer that never showed any HER2 protein (HER2-zero). The goal is to see if it can shrink tumors and improve outcomes for those who have already had standard treatments.
New Haven, ConnecticutAges 18 years+ - NCT06709651Recruiting
Gut bacteria treatment for triple-negative breast cancer
This trial tests whether a treatment that targets your gut bacteria (microbiome) can help fight triple-negative breast cancer before surgery. It is for people with newly diagnosed, untreated triple-negative breast cancer that has not spread far.
Cork, MunsterAges 18 years+ - NCT06371274Recruiting
Oral vitamin A drug plus immunotherapy for advanced triple-negative breast cancer
This trial tests a combination of an oral vitamin A-based drug (all-trans retinoic acid) and an immunotherapy (toripalimab) for people with advanced triple-negative breast cancer that hasn't responded to at least two prior treatments. The goal is to see if this combination can shrink or control the cancer.

Common questions
- Are there clinical trials for unresectable breast cancer?
- Yes. Clin2 currently lists 266 recruiting unresectable 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 unresectable 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 unresectable 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.
