New drug combo for early relapsed triple-negative breast cancer
This trial tests experimental drugs for people with triple-negative breast cancer that came back within 12 months of finishing initial treatment. The goal is to see if these drugs are safe and can shrink or slow the cancer.
VillejuifAges 18 years+ - NCT06512350Recruiting
Breath test for breast cancer patterns
This study is testing whether a simple breath test can help find patterns linked to breast cancer. If you are scheduled for a breast biopsy or MRI, you may be eligible to participate.

Tirzepatide for weight loss in MRD-positive early breast cancer
This study tests whether the weight-loss drug tirzepatide (Mounjaro) can help prevent breast cancer from coming back in people who are overweight and have a sign of leftover cancer cells in their blood (called MRD-positive). You must have already finished at least one year of hormone therapy for early-stage breast cancer.
Dallas, TexasAges 18 years+ - NCT06532812RecruitingPhase 1/Phase 2
TIL therapy plus immunotherapy for advanced breast cancer

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,473 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.
