Nanjing, JiangsuAges 18–75 - NCT07340398RecruitingPhase 2
Testing new drug combos for HER2-positive breast cancer not responding to first therapy
This trial tests a new combination of drugs for people with HER2-positive early breast cancer whose tumors did not respond well to the first round of standard targeted therapy plus chemo. The goal is to see if switching to trastuzumab-rezetecan plus pertuzumab or a different chemo combo (nab-paclitaxel, carboplatin, trastuzumab, and pyrotinib) can shrink the tumor before surgery.
HangzhouAges 18–75 - NCT07327021RecruitingPhase 2
MRI-Guided treatment reduction for stage 2-3 triple-negative breast cancer
This trial tests if using MRI scans can safely reduce the amount of chemotherapy and immunotherapy needed before surgery for triple-negative breast cancer. All patients will receive the standard KEYNOTE-522 regimen, but the treatment may be tailored based on MRI results.
Tel AvivAges 18 years+ - NCT07331506Recruiting
Early detection of breast cancer with a blood test
This trial tests a new blood test called Oncoliq to see if it can find breast cancer early. It compares results from people with breast cancer and people without cancer.
Buenos Aires, Buenos AiresAges 40–70 - NCT06035679Recruiting
