Surgery or radiation for stable HER2+ breast cancer spread
This study tests whether combining surgery or strong focused radiation with standard treatment can help people whose HER2-positive breast cancer has spread to a few spots (5 or fewer) in the body, but not the brain. It's for patients whose cancer is stable after at least 3 months of first-line therapy.
Basking Ridge, New JerseyAges 18 years+ - NCT07037576Recruiting
Breast reconstruction study for patients needing radiation after mastectomy
This study compares two types of breast reconstruction for women who need radiation therapy after their mastectomy: one-stage reconstruction using a permanent implant placed in front of the chest muscle, versus the standard two-stage approach where a tissue expander is used first and replaced with a permanent implant later. The goal is to see which method works better and is safer for patients who require post-mastectomy radiation.
Henan, HenanAges 18–70 - NCT07024173RecruitingPhase 3
HRS-8080 versus doctor's choice for advanced breast cancer
This trial tests a new medicine called HRS-8080 for locally advanced or metastatic breast cancer. It compares HRS-8080 with whatever treatment your doctor would normally choose for you.

Study of NKT5097 for advanced solid tumors
This trial tests an experimental oral drug (NKT5097) for people with advanced solid tumors that have not responded to other treatments. It may also be an option for people with a specific type of breast cancer (HR+/HER2-). The goal is to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07030569Recruiting

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