Recruiting studies
- NCT05332561RecruitingPhase 2
Personalized treatment after surgery for early breast cancer
This Phase 2 study checks whether adding a personalized (biomarker-matched) medicine after standard chemotherapy and surgery lowers the risk of breast cancer coming back. Your study drug choice depends on tumor test results (from your tumor’s genetics and immune markers).
Heidelberg, Baden-WurttembergAges 18 years+ - NCT05901428RecruitingPhase 3
Check if two breast cancer treatments work better after surgery
This trial compares two treatment approaches in people with high-risk hormone-positive, HER2-negative breast cancer that has spread to certain lymph nodes. It looks at which option works best to lower cancer returning and to control the disease after surgery and initial chemotherapy.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06551220Recruiting
T-DXd for advanced breast cancer with various HER2 levels
This study looks at how well the drug T-DXd (Enhertu) works against breast cancer that has spread or can't be removed with surgery. It includes patients with any level of HER2 protein, so it might be an option even if your cancer has low HER2.
New Haven, ConnecticutAges 18–80 - NCT06994377Recruiting
Emotional distress study for newly treated metastatic breast cancer
This trial studies emotional distress in people with metastatic breast cancer who have not yet received treatment for their advanced disease. It explores how different standard first-line therapies affect emotional well-being.
AnconaAges 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+ - 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+ - NCT07708571Recruiting
Coaching program for women on ribociclib and aromatase inhibitor
This study tests whether a coaching program based on personality types helps women with early-stage hormone receptor-positive, HER2-negative breast cancer stick to their treatment plan. Participants must be taking ribociclib (Kisqali) and an aromatase inhibitor, and their cancer must not have spread to other organs.
Augsburg, BavariaAges 18 years+ - NCT06832202RecruitingPhase 2
HLX22 plus Enhertu for HR+, HER2-low breast cancer
This trial tests a new drug, HLX22, combined with Enhertu (trastuzumab deruxtecan) for people with advanced breast cancer that is hormone receptor positive and HER2-low. The goal is to see if the combination works better than Enhertu alone.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07109726RecruitingPhase 1/Phase 2
Testing TER-2013 for advanced tumors with AKT/PI3K/PTEN changes
This trial tests a new drug called TER-2013, alone or combined with another drug (fulvestrant), for people with advanced solid tumors that have specific genetic changes in the AKT/PI3K/PTEN pathway. It aims to see if the drug is safe and effective.
Orlando, FloridaAges 18 years+ - NCT07661641RecruitingPhase 1
Study of new radioactive treatments for GRPR-positive tumors
This early-phase study tests two new radioactive treatments (lutetium-177 and actinium-225) together with a guided imaging agent in people with GRPR-positive solid tumors (including prostate, breast, or colorectal cancers). The goal is to see if these treatments can shrink tumors that have stopped responding to standard therapies.
Melbourne N., VictoriaAges 18 years+ - NCT05861830RecruitingPhase 3
Dalpiciclib plus hormone therapy after CDK4/6 treatment
This trial tests dalpiciclib together with hormone (endocrine) therapy in people with HR-positive, HER2-negative advanced breast cancer whose cancer has already responded poorly to a prior CDK4/6 inhibitor. It aims to see if this combination can better control the cancer after that earlier treatment has failed.
Beijing, Beijing MunicipalityAges 18–80 - NCT05985655RecruitingPhase 1/Phase 2
Study of GTAEXS617 for advanced solid tumors
This trial tests a new drug called GTAEXS617 for adults with certain advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT06312176RecruitingPhase 3
Study of new drugs for HR+/HER2- advanced breast cancer
This trial tests two new drugs (sacituzumab tirumotecan and pembrolizumab) against standard treatments for a type of advanced breast cancer that is hormone receptor positive and HER2 negative. It's for people whose cancer has worsened despite hormone therapy with a CDK4/6 inhibitor.
Chandler, ArizonaAges 18 years+ - NCT06301438Recruiting
Dalpiciclib for HR+/HER2- advanced breast cancer
This trial tests a drug called Dalpiciclib for people with a certain type of advanced breast cancer (HR-positive, HER2-negative). It aims to see if it can help stop the cancer from growing.
ShanghaiAges 18 years+ - NCT07137871RecruitingPhase 1
Avasopasem for advanced HR+ breast cancer after CDK 4/6 inhibitor
This trial tests a drug called avasopasem for people with hormone receptor-positive, HER2-negative breast cancer that has spread and gotten worse despite treatment with a CDK 4/6 inhibitor (ribociclib or abemaciclib) and hormonal therapy. It aims to see if adding avasopasem can help control the cancer.
San Antonio, TexasAges 18 years+ - NCT06255392RecruitingPhase 3
Fluzoparib with apatinib vs chemo for advanced breast cancer
This trial tests a combination of two oral targeted drugs (fluzoparib and apatinib) against standard chemotherapy for women with advanced, HRD-positive, HER2-negative breast cancer. It may be an option if you have already received some treatments but not too many.
