Recruiting studies
- NCT07227233RecruitingPhase 2
AI-guided retrial of CDK4/6 inhibitors for advanced breast cancer
This trial tests whether an artificial intelligence (AI) tool can help doctors decide if it is safe and effective to give you a second course of a CDK4/6 inhibitor drug (like palbociclib, ribociclib, or abemaciclib) plus hormone therapy for advanced (unresectable or metastatic) HR+/HER2- breast cancer. The goal is to only treat people whose cancer is likely to respond based on a special AI analysis of their tumor tissue.
La Jolla, CaliforniaAges 18 years+ - NCT07218432Recruiting
TheraBionic device study for hormone-positive breast cancer
This trial tests a device called TheraBionic P1, which uses low-level radiofrequency energy, for women with early-stage hormone receptor-positive, HER2-negative breast cancer. It is given before surgery to see if it can help shrink the tumor.

Tracking cancer DNA in blood to detect early return of breast cancer
This study tracks tiny traces of cancer DNA in the blood over time to see if it can find early signs of breast cancer coming back. It looks at different types of breast cancer and at different points in a patient's treatment journey.
Birmingham, AlabamaAges 18–99 - 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+ - 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+ - NCT07190443RecruitingPhase 3
Abemaciclib after local recurrence in HR+ HER2- breast cancer
This trial tests whether adding a targeted drug (abemaciclib) to standard treatment helps prevent breast cancer from coming back again after a local recurrence in women with HR-positive, HER2-negative breast cancer.
Koto-ku, TokyoAges 18 years+ - NCT06837792RecruitingPhase 2
T-DXd vs hormone therapy for HER2-low advanced breast cancer
This trial compares a targeted antibody-drug conjugate called T-DXd against standard hormone therapy for women with HR+, HER2-low advanced breast cancer that has progressed after first-line endocrine therapy plus a CDK4/6 inhibitor. It aims to see if T-DXd works better than continuing hormone therapy alone.
SeoulAges 19 years+ - NCT07179809Recruiting
Lifestyle program for women with metastatic breast cancer
This trial tests a group-based lifestyle program for women with HR+/HER2- metastatic breast cancer. The program helps you improve diet, increase physical activity, and learn mind-body practices in a supportive group setting.
Houston, TexasAges 18 years+ - NCT07180056Recruiting
CDK4/6 inhibitor after breast cancer surgery
This trial tests whether a CDK4/6 inhibitor given after surgery can help prevent breast cancer from coming back. It is for people with HR-positive, HER2-negative breast cancer that has not spread to other parts of the body.
ShanghaiAges 18 years+ - NCT07180160RecruitingPhase 2
A study of QL1706 for HR-positive, HER2-negative breast cancer
This trial tests a new drug combination (iparomlimab and tuvonralimab, also called QL1706) for people with advanced breast cancer that is hormone receptor-positive and HER2-negative. It may be an option if standard treatments have stopped working.
ShanghaiAges 18 years+ - NCT07164976RecruitingPhase 1/Phase 2
Ribociclib for advanced HR+ HER2- breast cancer
This trial tests a new combination of ribociclib and anastrozole as a first treatment for advanced hormone receptor-positive, HER2-negative breast cancer that has not been treated before. It may help if you have not received any prior therapy for metastatic disease.
NagoyaAges 18 years+ - NCT06207734RecruitingPhase 2
Stopping CDK4/6 inhibitors in advanced breast cancer
This trial looks at what happens when women with advanced hormone-positive, HER2-negative breast cancer stop taking a CDK4/6 inhibitor after at least a year of successful treatment. The goal is to see if it's safe to take a break from the CDK4/6 inhibitor while continuing hormone therapy alone.
BerlinAges 18 years+ - NCT07150208RecruitingPhase 2
T-DXd with or without Avastin for HER2-low breast cancer that spread to the brain
This trial tests a combination of two targeted drugs (T-DXd and bevacizumab) for people with HER2-low breast cancer that has spread to the brain. It aims to see if adding bevacizumab helps the main drug work better against brain metastases.
