- NCT06791161Enrolling by invitation
Adjuvant therapy study for BRCA1/2 positive breast cancer
This study tests if additional treatment after surgery helps prevent breast cancer from returning. It is for people with hormone receptor-positive, HER2-negative breast cancer who have a BRCA1 or BRCA2 gene mutation and a high risk of recurrence.
Beijing, Beijing MunicipalityAges 18–75 - 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+ - NCT06805812Recruiting
Predicting outcomes of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well a type of targeted therapy (called CDK4/6 inhibitors) combined with hormone therapy works as the first treatment for advanced breast cancer that is hormone receptor-positive and HER2-negative. Researchers want to find patterns that could help predict which patients benefit most.

London, OntarioAges 18 years+ - NCT05949541RecruitingPhase 2
Everolimus with first-line hormone therapy for specific breast cancer
This Phase 2 trial tests whether adding everolimus to standard first-line hormone (endocrine) therapy can better control a certain type of advanced breast cancer. It is designed for people whose tumor matches a specific “SNF1 subtype.”
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07409298Enrolling by invitation
AI support for breast cancer patients on CDK4/6 inhibitors
This trial tests whether an AI-powered management program can improve mental health and daily habits for people with HR+/HER2- breast cancer who are taking CDK4/6 inhibitor pills at home. It is designed to help you feel supported and stay on track with your rehabilitation plan.
TianjinAges 18–80 - NCT07180693Recruiting
Breast cancer that returns after CDK4/6 inhibitor treatment
This study looks at patients whose breast cancer returns after starting a CDK4/6 inhibitor (like abemaciclib or ribociclib) along with hormone therapy. The goal is to understand why the cancer comes back and find better ways to treat it.
Bergamo, ItalyAges 18 years+ - NCT06033287Recruiting
Real-world study of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well CDK4/6 inhibitors combined with hormone therapy work in real-world settings for people with a certain type of advanced breast cancer (HR+/HER2-). It aims to understand the best treatment path and what happens next.
Changsha, HunanAges 18 years+ - NCT07252726RecruitingPhase 4
Morning vs. evening dosing for metastatic breast or prostate cancer
This trial tests whether taking your hormone therapy and targeted pills in the morning or evening affects how well they work and how you feel. It is for people with metastatic breast or prostate cancer starting a specific hormone-based treatment combination.
Kitchener, OntarioAges 18 years+ - NCT06197581Recruiting
Safety of Radiation with Modern Breast Cancer Drugs
This study checks if giving certain modern breast cancer drugs at the same time as radiation is safe. It's for women who need radiation and are also taking one of these drugs: capecitabine, a CDK4/6 inhibitor, a PARP inhibitor, immunotherapy, or a HER2 inhibitor.
Beijing, Beijing MunicipalityAges 18–70 - NCT04819243RecruitingPhase 2
Test a BRCA-targeted drug plan for advanced ER-positive breast cancer
This Phase 2 study tests how well a treatment plan using palbociclib followed by talazoparib (and possibly atezolizumab) works in certain people with advanced ER-positive breast cancer. It may help by targeting cancer biology linked to BRCA/HRD changes and by strengthening how the cancer is controlled.
Seoul, Gannam-guAges 19 years+ - 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+ - 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+ - NCT05795335Recruiting
Testing CDK4/6 medicines for advanced hormone-positive breast cancer
This trial studies how CDK4/6 medicines fit into treatment for people with advanced hormone receptor–positive breast cancer that cannot be cured with surgery or radiation. It may help doctors understand the best way to use these medicines for disease that has returned or spread.

A new drug combo for HR+ advanced breast cancer
This trial tests a sequence of three drugs: first trastuzumab rezetecan (a targeted therapy), then a CDK4/6 inhibitor plus hormone therapy. It's for people with a type of breast cancer called HR-positive, HER2-low or ultra-low that has spread or come back and has already progressed on a CDK4/6 inhibitor and hormone therapy.

Conditions with recruiting CDK4/6 inhibitor studies.
Common questions
- Are there clinical trials studying CDK4/6 inhibitor?
- Yes. Clin2 currently lists 51 recruiting studies that include CDK4/6 inhibitor, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a CDK4/6 inhibitor trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is CDK4/6 inhibitor an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether CDK4/6 inhibitor or a specific trial is right for you.
