Studying inavolisib for a type of advanced breast cancer
This study tests a targeted therapy called inavolisib for people whose breast cancer has spread (advanced or metastatic), is hormone receptor-positive and HER2-negative, has a PIK3CA mutation, and has stopped responding to hormone therapy. It aims to see if inavolisib is safe and works well for them.

Sleep after breast cancer study
This study looks at how sleep changes during breast cancer treatment and how those changes relate to certain markers in the body. It aims to help improve sleep and overall health for people with hormone receptor positive breast cancer.
Columbus, OhioAges 18 years+ - NCT07331506Recruiting
Early detection of breast cancer with a blood test
This trial tests a new blood test called Oncoliq to see if it can find breast cancer early. It compares results from people with breast cancer and people without cancer.
Buenos Aires, Buenos AiresAges 40–70 - NCT07327970Recruiting
AI test to predict breast cancer treatment response
This study tests whether an AI tool can predict how well breast cancer responds to chemotherapy given before surgery. Your tumor sample from a needle biopsy will be analyzed to see if the AI's prediction matches your actual treatment outcome.
IncheonAges 18 years+ - NCT07318805RecruitingPhase 1
A study of PF-08032562 for advanced solid tumors
This study tests a new medicine, PF-08032562, for people with advanced breast or colorectal cancer that has not responded to prior treatments. It aims to see if the drug is safe and can help shrink or slow the cancer.
Duarte, CaliforniaAges 18 years+ - NCT07321145Recruiting
Robot vs. Endoscopic Breast-Conserving Surgery
This trial looks back at medical records to compare two types of breast-conserving surgery (robot-assisted vs. endoscopic) for women with early-stage breast cancer. It's for women who are good candidates for keeping their breast and who want a less invasive surgical option.
Guangzhou, GuangdongAges 18–80 - NCT06035679Recruiting
Combination therapy before surgery for HER2-positive breast cancer
This trial tests a combination of targeted therapies and chemotherapy given before surgery for HER2-positive breast cancer. It aims to see if this approach helps shrink tumors and improve outcomes.
Fuzhou, FujianAges 18–75 - NCT07310420RecruitingPhase 1
Evaluating ovarian suppression with ZOLADEX in premenopausal breast cancer
This trial tests a medication (ZOLADEX) to suppress ovarian function in premenopausal women with hormone receptor-positive breast cancer, either early-stage or advanced. The goal is to see how well it works and how safe it is.
Hot Springs, ArkansasAges 18–55 - NCT07311993RecruitingPhase 1
Study of CLR 125 for triple negative breast cancer
This trial tests an experimental drug called CLR 125 in people with triple negative breast cancer that has worsened after at least one prior treatment. It aims to see if the drug is safe and how it affects the cancer.
Jacksonville, FloridaAges 18 years+ - NCT06780735Recruiting
Breast-sparing surgery using a special dye after chemo
This trial tests a technique where doctors use a special dye (ICG) to guide breast-conserving surgery in patients whose tumors have shrunk enough after chemotherapy. The goal is to remove only the cancer while saving as much healthy breast tissue as possible.
Goyang-si, Gyeonggi-doAges 18 years+ - NCT07312786Recruiting
Virtual app for breast and colorectal cancer survivors
This study tests if a virtual app can help people who have finished treatment for breast or colorectal cancer feel supported and stay healthy. It looks at whether using the app is easy and helpful for cancer survivors.

Istanbul, IstanbulAges 18 years+ - NCT07304934Recruiting
New blood test model to check lymph node status in breast cancer
This study uses a blood test and imaging to predict whether breast cancer has spread to underarm lymph nodes, helping guide surgery. It may reduce unnecessary lymph node removal.

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.
