LondonAges 18 years+ - NCT06185972RecruitingPhase 2
MRI-guided ultrasound radiation for breast and chest cancer
This trial tests a new way to give radiation therapy using MRI imaging and ultrasound to make the radiation more targeted and potentially safer. If you have chest-wall or breast cancer and are already scheduled for radiation, this approach might offer a more precise treatment option.
Toronto, 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 - NCT06199895RecruitingPhase 2
Study of paclitaxel for patients with taxane-resistant solid tumors
This trial tests paclitaxel given as tiny micelle particles for people whose cancer (pancreatic, bile duct, lung, stomach, esophagus, or breast) stopped responding to taxane chemotherapy or did not shrink. The goal is to see if this treatment can help when standard taxanes no longer work.
Wuhan, HubeiAges 18 years+ - NCT06201234RecruitingPhase 2
Adding elacestrant to olaparib for advanced HR+/HER2- breast cancer
This trial tests if adding a new oral medicine (elacestrant) to a standard PARP inhibitor (olaparib) works better for people with advanced or metastatic HR+/HER2- breast cancer who have a BRCA1 or BRCA2 gene mutation. The goal is to see if the combination can help control the cancer longer.
Stuttgart, Baden-WurttembergAges 18 years+ - NCT06202118Recruiting
Alpha radiation therapy for breast cancer in older or frail patients
This trial tests a new type of radiation therapy (DaRT) that uses tiny, implantable seeds to deliver targeted alpha radiation to breast tumors. It is designed for older patients (65+) or those who are too frail for surgery, offering a less invasive option for controlling the cancer.
JerusalemAges 65–120 - NCT06202261RecruitingPhase 1/Phase 2
Study of TQB2930 for breast cancer that has returned or spread
This trial tests a new drug called TQB2930 alone or with other treatments for people with recurrent or metastatic breast cancer. It may help if you have a type of breast cancer called HER2-positive and have not had many prior treatments for advanced disease.
Chongqing, Chongqing 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.
