Shanghai, Shanghai MunicipalityAges 18–70 - NCT06185569Recruiting
French study on outcomes in HR+/HER2- early breast cancer patients with Oncotype DX
This study looks at how well treatments work for people with early-stage, hormone receptor-positive, HER2-negative breast cancer when the Oncotype DX test helps guide therapy. It aims to understand real-world outcomes in French patients.
BesançonAges 18 years+ - NCT06928701Recruiting
Diet and exercise for early breast cancer before surgery
This trial tests whether a personalized nutrition and exercise program can improve treatment response by changing how your body and immune system react to breast cancer before surgery. It is for women newly diagnosed with early-stage breast cancer who will receive neoadjuvant therapy (treatment before surgery).
Novara, NovaraAges 18 years+ - NCT07380646RecruitingPhase 2
Leucogen to prevent low white blood cells from ribociclib in early breast cancer
This trial tests if Leucogen can prevent neutropenia (low white blood cells) caused by ribociclib, a targeted therapy for hormone receptor-positive, HER2-negative early breast cancer. It may help you stay on treatment without delays or dose reductions.
Hangzhou, ZhejiangAges 18 years+ - NCT04997993RecruitingPhase 1
Leflunomide for PTEN-altered or HER2-negative metastatic cancers
This Phase 1 trial studies whether leflunomide can slow or control advanced (metastatic) cancers in people whose tumors have specific PTEN changes or who have HER2-negative breast cancer. It’s primarily a safety-and-dosing study, but it may offer benefit if your cancer matches the tumor marker requirements.
New York, New YorkAges 18 years+ - NCT07739485RecruitingPhase 1/Phase 2
Oral paclitaxel before surgery for triple-negative breast cancer
This trial tests an oral form of a common chemo drug, paclitaxel, given before surgery for triple-negative breast cancer. It aims to find the best dose and see how well it shrinks tumors.
Guiyang, GuizhouAges 18–70 - NCT04437160RecruitingPhase 2
Chemo after surgery for triple-negative breast cancer with leftover tumor
This Phase 2 study tests chemotherapy given after surgery for people with triple-negative breast cancer who still have cancer left after initial (neoadjuvant) chemo. It may help lower the chance the cancer comes back in people at higher risk based on leftover tumor and lymph node findings.
Beijing, Beijing MunicipalityAges 18–75 - NCT05582538RecruitingPhase 2
Ceralasertib plus immunotherapy for advanced triple-negative breast cancer
This Phase 2 trial tests whether a drug called ceralasertib can help the immune system work better, followed by durvalumab plus nab-paclitaxel. It is for people with advanced triple-negative breast cancer whose cancer returned after earlier treatment, including chemotherapy and immune therapy.
Novara, NovaraAges 18 years+ - NCT07666555RecruitingPhase 2
