Recruiting studies
- NCT07054190RecruitingPhase 2
Testing Inavolisib in early-stage breast cancer with PIK3CA mutation
This trial is testing a drug called Inavolisib (a type of targeted therapy) given before surgery for people with early-stage, hormone receptor-positive, HER2-negative breast cancer that has a specific genetic change (PIK3CA mutation).

Houston, TexasAges 18 years+ - NCT07195227RecruitingPhase 2
Camizestrant plus ribociclib for advanced breast cancer
This trial tests a combination of two drugs, camizestrant and ribociclib, for people with a certain type of advanced breast cancer (HR+/HER2-). It is for those whose cancer has grown or spread despite previous hormone therapy. The goal is to see if this new combination can help control the cancer.
DessauAges 18 years+ - NCT07198724RecruitingPhase 1/Phase 2
A study of elacestrant plus Enhertu for advanced breast cancer
This trial tests a new combination of two targeted drugs (elacestrant and Enhertu) for people with a specific type of advanced breast cancer (HR-positive, HER2-low or ultra-low) that did not respond to standard treatments like CDK4/6 inhibitors. The goal is to see if this combination works better than current options.
Boston, MassachusettsAges 18 years+ - NCT07220135RecruitingPhase 2
Comparing two drug combos before surgery for HER2+ breast cancer
This trial tests two different combinations of chemotherapy and targeted therapy given before surgery for HER2-positive breast cancer. The goal is to see which combination works better at shrinking the tumor.
Fairway, KansasAges 18 years+ - NCT07251868Recruiting
Study of SG in breast cancer with brain metastases
This study follows patients with breast cancer that has spread to the brain and who have already received the drug Sacituzumab Govitecan (SG). The goal is to learn how well SG works in real-world settings and to see how patients are doing over time.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07273357Recruiting
CDK4/6 inhibitors for older breast cancer patients
This study looks at how well older breast cancer patients (70 years and older) do when treated with a type of drug called a CDK4/6 inhibitor along with hormone therapy after surgery. The goal is to use simple health checks to help doctors decide if this treatment is right for you.
GävleAges 70 years+ - NCT07274852RecruitingPhase 1
Study of a radioactive drug for advanced solid tumors
This trial tests a new radioactive drug (177Lu-BL-ARC001) for people with advanced lung, breast, head and neck, or other solid tumors that have not responded to standard treatments. It aims to see if the drug can target and shrink tumors while limiting side effects.
Chengdu, SichuanAges 18 years+ - NCT07297134Recruiting
PTEN and Organ-Specific microRNAs in Breast Cancer
This trial looks at specific molecules (PTEN and microRNAs) in the blood to see if they help doctors understand how breast cancer spreads. If you have breast cancer (whether it has spread or not) or are healthy, you might be eligible.
Istanbul, IstanbulAges 18 years+ - NCT07341503Recruiting
