Testing gene activity to guide breast cancer treatment
This study links breast tumor test results from MammaPrint and optional BluePrint (and full genetic data) with real-world clinical information to understand which new gene activity patterns matter. It may help future patients by improving how doctors use these tests to guide care.
Birmingham, AlabamaAges 18 years+ - NCT06522568Recruiting
Breast cancer screening decision help for rural patients
This study tests a decision aid that helps women aged 39-49 decide about mammograms. It aims to support informed choices in rural areas.
Keene, New HampshireAges 39–49 - NCT06523894Recruiting
Radiation therapy for breast cancer patients over 70
This trial tests a precise type of radiation called SBRT for breast cancer in patients aged 70 or older who cannot have surgery or choose not to. The goal is to see if this treatment can effectively control the tumor without surgery.
GenevaAges 70 years+ - NCT06458712RecruitingPhase 1
Testing a new drug for advanced cancers with gene changes
This study tests a new oral drug, DSB2455, for people with advanced breast, prostate, ovarian, or pancreatic cancers that have certain gene changes. It aims to see if the drug is safe and whether it helps shrink or control the cancer.
Sacramento, CaliforniaAges 18 years+ - NCT06439771RecruitingPhase 2
Testing YL202 for advanced breast cancer
This trial tests a new drug called YL202 for people with advanced breast cancer. It is for those who have already tried certain targeted treatments (HER2 or TROP2 antibody-drug conjugates) and they stopped working. The goal is to see if YL202 can help shrink tumors or slow cancer growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06353997RecruitingPhase 2
Neoadjuvant INBRX-106 with pembrolizumab for early-stage triple-negative breast cancer
This trial tests whether adding an experimental drug called INBRX-106 to the standard immunotherapy (pembrolizumab) and chemotherapy before surgery can improve outcomes for patients with early-stage triple-negative breast cancer. The goal is to shrink the tumor and potentially reduce the risk of the cancer coming back.

Common questions
- Are there clinical trials for primary breast cancer?
- Yes. Clin2 currently lists 711 recruiting primary 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 primary 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 primary 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.
