Recruiting studies
- NCT06790693RecruitingPhase 3
Inavolisib plus hormone therapy for advanced breast cancer
This trial tests a new targeted therapy, inavolisib, combined with standard hormone therapy and a CDK4/6 inhibitor for people with a specific genetic mutation (PIK3CA) in their hormone receptor-positive, HER2-negative advanced breast cancer that has not been treated before. It compares this combination to a placebo plus the same standard treatments.

This study looks at how doctors in China treat hormone receptor-positive, HER2-negative breast cancer that has spread, when patients are starting their second line of therapy. The goal is to learn more about real-world treatment patterns and results, which may help you and your doctor make more informed treatment decisions.
Nanjing, JiangsuAges 18 years+ - NCT04540692RecruitingPhase 3
Testing chemotherapy timing for certain HER2-negative breast cancers
This Phase 3 trial studies different ways of giving common chemotherapy drugs (anthracyclines and taxanes) for locally advanced breast cancer that is HER2-negative. It aims to see which order or “sequencing” may work better for people like you.
Cachoeiro de Itapemirim, Espírito SantoAges 18 years+ - NCT04660435Recruiting
Study how breast cancers resist CDK4/6 inhibitor treatment
This study looks at why some ER-positive, HER2-negative metastatic breast cancers don’t respond well to CDK4/6 inhibitors combined with hormone therapy. It may help researchers understand resistance and improve future treatment choices for people like you.
Prato, TuscanyAges Any age - NCT06970912RecruitingPhase 2
ctDNA-Guided Reduced Chemo in HR+/HER2- Breast Cancer
This study is testing whether using a ctDNA blood test can help doctors decide if patients with hormone receptor-positive, HER2-negative breast cancer can safely receive less intensive chemotherapy after surgery. The goal is to reduce side effects while still preventing the cancer from coming back.
Beijing, Beijing MunicipalityAges 18–75 - NCT07366112RecruitingPhase 2
CDK4/6 inhibitor plus hormone therapy before breast cancer surgery
This trial tests a combination of a CDK4/6 inhibitor (a type of targeted therapy) with hormone therapy given before surgery for early-stage breast cancer that is hormone receptor-positive and HER2-negative. It aims to see if this approach can shrink tumors and improve outcomes.
Beijing, Beijing MunicipalityAges 18–75 - NCT05095207RecruitingPhase 1/Phase 2
Abemaciclib and bicalutamide for HER2-negative metastatic breast cancer
This Phase 1/2 trial tests whether combining abemaciclib with bicalutamide can slow or shrink HER2-negative, androgen receptor–positive (AR-positive) metastatic breast cancer. It mainly looks at safety and side effects, and also whether the combination can help patients with this type of breast cancer.
New York, New YorkAges 18–90 - NCT05216432RecruitingPhase 1
RLY-2608 for PIK3CA-mutant advanced solid tumors and breast cancer
This early study (Phase 1) tests RLY-2608, a targeted cancer drug for tumors with a PIK3CA mutation. It studies the drug alone and combined with hormone therapy (and sometimes CDK4/6 or CDK4 medicines) to see safety, dose, and whether it can shrink tumors.
Tucson, ArizonaAges 18 years+ - NCT05333328RecruitingPhase 4
Test of ovarian function suppression for low-risk premenopausal node+ breast cancer
This trial studies whether ovarian function suppression (a treatment that lowers hormone production from the ovaries) helps women with hormone-receptor positive, HER2-negative breast cancer that has spread to lymph nodes, but who have a low-risk result on a genomic test. It may help reduce breast cancer recurrence while avoiding more intensive treatment for those who are lower risk.
Seoul, KoreaAges 20–50 - NCT05378204Recruiting
Testing DNA repair marker for PARP inhibitor resistance
This study looks at specific DNA “damage repair” proteins as a marker to understand why some BRCA-mutated breast cancers may resist PARP inhibitor treatment. Your biopsy (or existing biopsy) helps researchers study whether these lab markers relate to how well PARP inhibitors work.
BordeauxAges 18 years+ - NCT05430399RecruitingPhase 3
Utidelone vs docetaxel for HER2-negative breast cancer
This trial compares utidelone with docetaxel in people with HER2-negative advanced or metastatic breast cancer. It aims to see which treatment works better and is safer for controlling the cancer and helping patients live longer.
Guangzhou, GangdongAges 18 years+ - NCT05452213RecruitingPhase 4
Study patterns of ribociclib response and resistance in breast cancer
This trial looks at how well ribociclib works and why it may stop working over time in people with advanced, hormone-receptor–positive, HER2-negative breast cancer. It also analyzes blood and tissue samples to help researchers understand resistance patterns and improve future treatment decisions.
Erlangen, BavariaAges 18 years+ - NCT05837455RecruitingPhase 2
Biomarker-guided treatment for early breast cancer before surgery
This trial looks at whether using tumor test results (biomarkers) can help guide the best hormone treatment and chemotherapy before surgery. It focuses on people with stage II or III, ER-positive, HER2-negative breast cancer, with the goal of improving how well the tumor responds before it is removed.
St Louis, MissouriAges 18 years+ - NCT05918094RecruitingPhase 3
Testing new chemo plan plus immunotherapy for stomach cancer
This phase 3 study compares two versions of a first-time treatment for HER2-negative advanced stomach or gastroesophageal cancer, both including immunotherapy (sintilimab). It looks for a safer or more effective way to slow cancer growth or improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT05981014RecruitingPhase 1/Phase 2
Immune cells from lymph nodes for HER2-negative breast cancer
This trial tests whether taking immune cells from your lymph nodes and giving them back to you can help shrink breast cancer that has not responded fully to initial chemotherapy. It is for women with HER2-negative breast cancer who have had stable disease after two cycles of a standard chemotherapy combination.
Guangzhou, GuangdongAges 18–70 - NCT05981001RecruitingPhase 1/Phase 2
Experimental cell therapy for advanced HER2-negative breast cancer
This study tests a new treatment for advanced HER2-negative breast cancer. Doctors will take immune cells from lymph nodes near your tumor, grow them in a lab, and then give them back to you along with chemotherapy and immunotherapy. This approach aims to help your body fight the cancer more effectively.
Guangzhou, GuangdongAges 18–70 - NCT05982093RecruitingPhase 2
Elacestrant with or without triptorelin for premenopausal breast cancer
This trial tests a new hormone-blocking pill (elacestrant) with or without a shot that temporarily stops ovaries (triptorelin) for premenopausal women with early-stage, hormone-sensitive breast cancer. It aims to find a gentler treatment option before surgery.

Dapagliflozin with chemo for breast cancer
This trial tests whether adding the drug dapagliflozin (a pill that lowers blood sugar) to standard chemotherapy before breast cancer surgery can improve outcomes. It is for women with high insulin levels and a higher BMI who are about to start chemotherapy.
New Haven, ConnecticutAges 18 years+ - NCT06112613Recruiting
Mobile health to help with breast cancer pill-taking
This study uses text messages to help people with metastatic breast cancer remember to take their daily pills and asks about any missed doses. It aims to improve how well patients stick to their CDK4/6 inhibitor medication.
Fairbanks, AlaskaAges 18 years+ - NCT06121557RecruitingPhase 1
Immune cells from lymph nodes for advanced HER2-negative breast cancer

Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.
BrusselsAges 18–100 - NCT06177041RecruitingPhase 3
M108 plus chemo for CLDN18.2-positive stomach cancer
This trial tests a new drug (M108) combined with standard chemotherapy (CAPOX) as a first treatment for people with advanced stomach or gastroesophageal junction cancer that has a specific protein called Claudin 18.2. The goal is to see if adding M108 helps improve outcomes compared to chemotherapy alone.
