Recruiting studies
- NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.

Tucatinib and capecitabine plus spinal trastuzumab for HER2+ cancer
This Phase 2 trial tests a combination of tucatinib and capecitabine (taken by mouth) plus trastuzumab delivered into the spinal fluid, to treat breast cancer that has spread to the leptomeninges (lining around the brain/spinal cord). It may help reduce cancer activity in the spinal fluid and improve symptoms.

Side effects and quality of life after breast cancer treatment in China
This study looks at how local treatments like surgery, chemotherapy, radiation, hormone therapy, or targeted therapy affect your side effects and quality of life. Researchers want to learn from women with early-stage breast cancer to improve care.

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.
