Beijing, chaoyangAges 18 years+ - NCT07407920RecruitingPhase 2
Optimizing treatment for early HER2+ and triple-negative breast cancer
This trial aims to see if patients who had a complete response to chemo before surgery can safely stop or reduce their targeted therapy afterward. It includes people with early-stage HER2-positive or triple-negative breast cancer who had no cancer cells left in the tissue removed at surgery (a pathological complete response).
Houston, TexasAges 18 years+ - NCT05856383Recruiting
HER2-positive metastatic breast cancer drug combination study
This trial tests whether inetetamab combined with pyrotinib and vinorelbine works better and is safe for adults with HER2-positive advanced breast cancer. You may be considered if standard options have not removed the cancer with surgery and your body can handle chemotherapy and HER2-targeting medicines.
Hangzhou, ZhejiangAges 18 years+ - NCT05868226RecruitingPhase 1
Early cancer drug study for adults with advanced tumors
This Phase 1 study tests early (first-in-program) cancer medicines in people whose cancer has not been adequately controlled. It helps researchers learn the safest dose and early signs of whether the treatment may work for different tumor types and treatments.
Birmingham, AlabamaAges 18 years+ - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT05878314Recruiting
Testing how hormones and tumor markers guide breast cancer treatment
This study looks at how planned hormone (endocrine) treatment, the menstrual cycle, and lab markers from the tumor may help doctors choose the best treatment for early-stage, hormone-receptor–positive, HER2-negative breast cancer. It may help personalize decisions, including what to do before surgery.
TübingenAges 18 years+ - NCT05883852RecruitingPhase 3
HER2-positive breast cancer trial for women with lymph node spread
This Phase 3 trial compares two post-surgery drug plans for HER2-positive early breast cancer that has spread to nearby lymph nodes. It may help reduce cancer recurrence by testing which regimen works better after surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05891561RecruitingPhase 2
Short antibody treatment after surgery for early HER2+ breast cancer
This Phase 2 study tests a shorter schedule of trastuzumab and pertuzumab combined with chemotherapy (taxanes) to reduce breast cancer coming back after surgery. It mainly helps people with early-stage, HER2-positive breast cancer that has not spread, by testing whether a shorter plan still works well and is tolerable.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05894239RecruitingPhase 3
Tested targeted drug for HER2-positive breast cancer with PIK3CA changes
This Phase 3 study tests inavolisib plus Phesgo versus placebo plus Phesgo in people whose breast cancer has both HER2-positive and PIK3CA-mutated tumor markers. The goal is to see if adding inavolisib improves how well the treatment controls the cancer and how safe it is.
Gilbert, ArizonaAges 18 years+ - NCT05900206RecruitingPhase 2
Trastuzumab deruxtecan vs standard chemotherapy before breast surgery
This Phase 2 study compares trastuzumab deruxtecan to standard chemotherapy given before surgery for HER2-positive breast cancer. It aims to see which treatment works better to shrink the tumor and spread before the operation.
MalmöAges 18 years+ - NCT05910398RecruitingPhase 3
Extending anti-HER2 treatment after breast cancer surgery
This Phase 3 trial tests whether continuing or pausing the anti-HER2 medicine pyrotinib after surgery can lower the chance that invasive HER2-positive breast cancer comes back. It may help people who have recently finished trastuzumab or T-DM1 and are well enough to take tablets.
ShanghaiAges 18 years+ - NCT05918328RecruitingPhase 2
Testing two medicines before surgery for HER2-positive breast cancer
This Phase 2 trial compares nab-PH plus pyrrolitinib versus TCbHP as treatment given before breast surgery. It aims to see which option works better and is safe for people with HER2-positive invasive breast cancer.
Zhengzhou, HenanAges 18–65 - NCT05950945RecruitingPhase 3
Trastuzumab deruxtecan for HER2-low metastatic breast cancer
This trial tests a targeted antibody-drug medicine (trastuzumab deruxtecan, T-DXd) in people with metastatic breast cancer that is HER2-low or HER2 IHC 0. It may help by treating tumors that haven’t previously received anti-HER2 treatment in the metastatic setting.
Miami Beach, FloridaAges 18 years+ - NCT05955170RecruitingPhase 2
Tucatinib plus oral chemo and trastuzumab for metastatic HER2+ breast cancer
This Phase 2 trial studies tucatinib combined with oral etoposide and trastuzumab in people with metastatic HER2-positive breast cancer, aiming to slow cancer growth. You may be eligible if you previously had progression on a similar HER2-targeted treatment or cannot take capecitabine for medical reasons.
