Jonesboro, ArkansasAges 18 years+ - NCT07726342RecruitingPhase 2
Study of a new drug for advanced HER2-positive breast cancer
This study tests a new drug, SMP-656, for people with advanced HER2-positive breast cancer that has stopped responding to previous treatments. The goal is to see if it can help shrink or control the cancer.
Hefei, AnhuiAges 18 years+ - NCT07203729RecruitingPhase 2
A new drug for advanced breast cancer with severe symptoms
This trial tests a new drug called SHR-A1811 (a type of targeted therapy) for people with advanced breast cancer that is HER2-low and is causing severe symptoms (visceral crisis). The drug is given alone and aims to control the cancer and relieve symptoms.
Beijing, Beijing MunicipalityAges 18–75 - NCT07743190RecruitingPhase 2
Lighter chemo for early-stage triple-negative breast cancer with high immune cells
This trial tests a less intense chemotherapy regimen (without one of the standard drugs) combined with immunotherapy for people with early-stage triple-negative breast cancer whose tumors have a high level of immune cells (TILs). The goal is to see if this approach is effective while reducing side effects.
Syracuse, New YorkAges 18 years+ - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.
Nanchang, JiangxiAges 18–75 - NCT04481932RecruitingPhase 2
Trastuzumab with chemo for HER2-positive breast cancer
This Phase 2 study tests whether adding trastuzumab (a targeted antibody) given with chemo and extra drugs can better treat certain HER2-positive, locally advanced or inflammatory breast cancers. It may help by improving cancer control in people who have not had prior anti-cancer treatment for their breast cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT03646955Recruiting
Partial breast radiation versus no radiation after lumpectomy
This trial compares giving radiation only to part of the breast versus not giving radiation at all after breast-conserving surgery. It’s meant for women with early, hormone-driven breast cancer to see if skipping radiation can be safe and reduce treatment burden.
SantiagoAges 60 years+ - NCT03591276RecruitingPhase 1/Phase 2
Doxorubicin plus pembrolizumab for hormone-resistant breast cancer
This Phase 1b/2 trial tests a combination of pegylated liposomal doxorubicin and pembrolizumab for breast cancer that no longer responds to hormone treatment. It aims to see how well the combination works and how safely it can be given to patients with advanced disease.
JerusalemAges 18 years+ - NCT04159818RecruitingPhase 2
Adding immune treatments to improve checkpoint drug response in TNBC
This Phase 2 trial tests strategies meant to “prime” the immune system so that immune checkpoint medicines may work better in people with triple-negative breast cancer that has spread (or can’t be fully cured). You might be considered if your cancer has measurable areas that can be biopsied and you meet specific health and prior-treatment rules.
AmsterdamAges 18 years+ - NCT04698252RecruitingPhase 2
Local treatment for ER/PR-positive limited spread breast cancer
This Phase 2 study tests whether treating a small number of metastatic spots with a local approach (like targeted radiation, surgery, or ablation) can help people with ER/PR-positive breast cancer. It aims to help when the cancer has spread only to a few areas and has not significantly worsened after initial whole-body treatment.
São Paulo, São PauloAges 18 years+ - NCT05753657RecruitingEarly Phase 1
Testing insulin and blood sugar monitoring with pioglitazone
This early study tests whether adding pioglitazone, along with close blood-sugar (glucose/insulin) monitoring, can help control high insulin and high blood sugar in people starting alpelisib for metastatic breast cancer. It may help reduce blood-sugar side effects from alpelisib.
HaifaAges 18–85 - 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+ - NCT05851014RecruitingPhase 3
GB491 plus letrozole for HR+ HER2- advanced breast cancer
This Phase 3 study tests whether GB491 used together with letrozole works better for hormone receptor–positive and HER2-negative advanced breast cancer. You may be eligible if you have not had certain prior cancer treatments and your health tests are within safe limits.
Bengbu, AnhuiAges 18–75 - NCT05447702RecruitingPhase 2
Testes pre-surgery treatment for triple-negative breast cancer
This trial studies giving camrelizumab plus apatinib and chemotherapy before surgery for triple-negative breast cancer. The goal is to shrink the tumor and improve outcomes by testing a combination of immune and targeted medicines along with chemotherapy.
Chengdu, SichuanAges 18–75 - NCT05890287Recruiting
Chidamide plus hormone therapy after chemotherapy for breast cancer
This trial studies chidamide added to standard hormone (endocrine) therapy to help prevent breast cancer from coming back after initial chemotherapy. It may help by keeping cancer under control for longer in people with HR-positive, HER2-negative breast cancer who respond to first-line treatment.
TianjinAges 18–75 - NCT04020575RecruitingPhase 1
CAR T cells made from your blood for advanced breast cancer
This Phase 1 trial tests CAR T cells made from your own immune cells to target advanced breast cancer. The cells are designed to recognize a specific cancer marker (called MUC1*), with the goal of shrinking tumors or keeping them under control.
Duarte, CaliforniaAges 18 years+ - NCT05058183Recruiting
Testing shorter chemotherapy for early HER2 or triple‑negative breast cancer
This study looks at whether some people with stage 1 HER2-positive or “triple-negative” breast cancer may safely need less (de-escalated) chemotherapy after surgery. The goal is to keep the cancer risk low while reducing treatment intensity, using special blood testing over time.
LondonAges 18 years+ - NCT05916755Recruiting
Testing tumor clues that predict response to immunotherapy
This study looks for “biomarkers,” or tumor clues, that may help predict who benefits from checkpoint inhibitor immunotherapy in triple-negative breast cancer. It may help doctors choose the right treatment approach in the future, especially when chemotherapy is planned.
