Nasal spray before breast-saving surgery for calm wakefulness
This trial tests a nasal spray (dexmedetomidine) given before breast-conserving surgery to help you stay calm and comfortable while awake during the procedure. It aims to improve your recovery and waking experience after surgery.
TianjinAges 20–70 - NCT07327489Recruiting
Live tumor biopsy study to predict immunotherapy response
This trial studies how well immunotherapy might work by analyzing fresh tumor biopsies. It may help predict which treatments are best for your cancer.
Fort Smith, ArkansasAges 18 years+ - NCT07290309Recruiting
Remote exercise program for cancer survivors
This study tests a remote guided exercise program for cancer survivors to see if it helps with recovery and well-being. It is designed for people who have finished their main cancer treatments and are not already exercising a lot.
Fort Collins, ColoradoAges 18 years+ - NCT06877416Recruiting
Optimizing sequential ADC therapy for HER2-low breast cancer
This trial is for people with HER2-low breast cancer who have already received two or more antibody-drug conjugates (ADCs) in a row. Researchers want to find the best order to use these targeted therapies to get the most benefit.
Guangzhou, GuangdongAges Any age - NCT07268846Recruiting
Prebiotic supplement before colorectal cancer surgery
This trial tests if taking a postbiotic supplement before surgery for colorectal cancer can improve recovery. It may help patients with adenocarcinoma of the large intestine prepare for their operation.
São Paulo, São PauloAges 18 years+ - NCT07242352RecruitingPhase 3
Comparing elacestrant to standard hormone therapy for high-risk early breast cancer
This trial tests a new hormone therapy drug called elacestrant against standard hormone treatments for people with a specific type of early breast cancer (ER+/HER2-) that has a high chance of coming back. The goal is to see if elacestrant works better at keeping the cancer from returning.
Mannheim, Baden-WurttembergAges 18 years+ - NCT07112053RecruitingPhase 2
Vaccine with hormone therapy or chemo for advanced breast cancer
This trial tests a vaccine (STEMVAC) given with your standard hormone therapy or chemotherapy. It is for people with advanced hormone receptor-positive, HER2-negative breast cancer who are already on certain treatments. The goal is to see if adding the vaccine can help control the cancer better.
Seattle, WashingtonAges 18 years+ - NCT07078604RecruitingPhase 2
Vaccine with chemotherapy for advanced triple-negative breast cancer
This trial tests a cancer vaccine called STEMVAC combined with chemotherapy in people with a type of breast cancer that has spread and does not have certain markers. The goal is to see if adding the vaccine helps the chemotherapy work better.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,418 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.
