Recruiting studies
- NCT07208149RecruitingPhase 1/Phase 2
Study of MR001 for advanced triple-negative breast cancer
This trial tests a new drug, MR001, for people with triple-negative breast cancer that has come back or spread. It's for those who've already tried at least one type of treatment.
BeijingAges 18–75 - NCT07207070RecruitingPhase 3
New drug combination for PIK3CA-mutated breast cancer
This trial tests a new combination of two drugs (JS105 plus dalpiciclib and fulvestrant) against a standard combination (dalpiciclib plus fulvestrant) for people whose breast cancer has a PIK3CA mutation. The goal is to see if adding JS105 helps control the cancer longer.
Beijing, Beijing MunicipalityAges 18–75 - NCT05288777RecruitingPhase 2/Phase 3
Testing follow-up chemo and radiation for high-risk breast cancer
This trial studies a standard follow-up treatment plan that combines chemotherapy and radiation after surgery, and it looks for blood/tissue “biomarkers” that predict who benefits most. If you have high-risk breast cancer that didn’t fully disappear after initial (neoadjuvant) chemo, you may be eligible to help guide better future treatment choices.
Charlottesville, VirginiaAges 18 years+ - NCT06702995RecruitingPhase 1/Phase 2
Study of XNW5004 plus enzalutamide for advanced prostate cancer
This trial tests a new drug, XNW5004, combined with enzalutamide for men with metastatic castration-resistant prostate cancer that has progressed despite other treatments. It aims to see if this combination can slow the cancer's growth.
Jinan, ShandongAges 18 years+ - NCT06938360Recruiting
Breast-conserving surgery for central breast cancer study
This trial compares breast-conserving surgery (removing only the tumor and nearby tissue) to total mastectomy (removing the whole breast) for women with breast cancer in the central area of the breast. The goal is to see if the less extensive surgery works just as well.
Xi'an, ShaanxiAges 18–70 - 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+ - NCT07195344RecruitingPhase 4
T-DXd for breast cancer: comparing drug levels by BMI
This trial studies how the drug T-DXd (trastuzumab-deruxtecan) works in people with advanced or metastatic breast cancer. It compares drug levels in the body based on body mass index (BMI) to see if dose adjustments are needed.
AngersAges 18 years+ - NCT07201194Recruiting
Acupuncture for chemotherapy nausea
This trial tests if acupuncture can help reduce nausea in people who still feel sick despite taking their regular anti-nausea medication during chemotherapy.
VejleAges 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+ - NCT05535413RecruitingPhase 1/Phase 2
UTD1 plus capecitabine for HER2-negative breast cancer brain mets
This trial tests whether adding a study drug called UTD1 to capecitabine can shrink or control breast cancer that has spread to the brain. It’s for people with HER2-negative metastatic breast cancer who have brain metastases and meet specific safety and lab requirements.
ChangshaAges 18–70 - NCT07190469RecruitingPhase 1
PQ203 for advanced solid tumors like triple-negative breast cancer
This early-phase trial tests a new drug called PQ203 for people with advanced solid tumors, including triple-negative breast cancer, that have stopped responding to standard treatments. It helps doctors learn whether the drug is safe and how it affects tumors.
Houston, TexasAges 18 years+ - NCT07188246RecruitingPhase 2
Radiation and immunotherapy before chemo for breast cancer
This trial tests a new approach for breast cancer that combines a short course of focused radiation (SBRT) with an injection of the immunotherapy drug pembrolizumab directly into the tumor, followed by standard chemotherapy before surgery. The goal is to see if this combination helps shrink the tumor more effectively before surgery.
London, OntarioAges 18 years+ - NCT07191717RecruitingPhase 2
Imlunestrant and abemaciclib for early ER+ breast cancer
This trial tests whether adding two targeted drugs, imlunestrant and abemaciclib, to your usual hormone therapy can lower the chance of your breast cancer coming back. It is for people with early-stage ER+ breast cancer who have no signs of cancer on scans but have tiny amounts of tumor DNA in their blood (called ctDNA).
Los Angeles, CaliforniaAges 18 years+ - NCT07193394RecruitingPhase 2
Tucatinib and trastuzumab for HER3-mutant breast cancer
This trial tests a combination of two targeted drugs (tucatinib and trastuzumab) for people with a specific gene change (HER3 mutation) in advanced breast cancer that has spread or cannot be removed by surgery. It may be an option if you have already had at least two previous treatments.
BordeauxAges 18 years+ - NCT06225284RecruitingPhase 2
Chemotherapy with or without hormone drug for premenopausal TNBC
This trial tests whether adding a hormone-blocking drug (GnRH agonist) to standard chemotherapy before surgery helps premenopausal women with triple-negative breast cancer. It aims to improve treatment outcomes by targeting hormones that may fuel tumor growth.
TaipeiAges 18 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.

This trial is testing a combination of two targeted therapies, SKB264 and Inetetamab, for people with advanced HER2-positive breast cancer that has kept growing after treatment with T-DXd and other HER2-targeted therapies. The goal is to see if this new combination can shrink tumors or slow the cancer's growth.
ShanghaiAges 18 years+ - NCT05835570Recruiting

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+ - NCT07173868Recruiting
PET scans for advanced breast cancer treatment planning

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+ - NCT07162675Recruiting
Step count and treatment response in breast cancer patients
This study looks at how your daily step count, measured by a smartwatch, relates to how well your breast cancer responds to treatment before surgery. It may help show if being more active during chemotherapy leads to better outcomes.

- How do I know if I qualify for a metastatic 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 metastatic 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.
