Pavia, LombardyAges 18–90 - NCT06053086Recruiting
Adaptive radiation therapy for breast cancer patients at high risk
This trial tests a new way to deliver radiation therapy that adapts to each patient's body changes during treatment. It is for women who had breast cancer surgery and need radiation to the whole breast and nearby lymph nodes, and who have been identified as being at risk for breast fibrosis.
MontpellierAges 18 years+ - NCT04543799Recruiting
Sleep quality study in prostate and early breast cancer patients
This trial studies how sleep quality changes while people with prostate cancer or early breast cancer receive standard treatments. It may help doctors understand which treatment factors affect sleep and identify who might benefit from support for sleep problems.
BellinzonaAges 18 years+ - NCT05800275RecruitingPhase 2
Tucatinib and capecitabine plus spinal trastuzumab for HER2+ cancer
This Phase 2 trial tests a combination of tucatinib and capecitabine (taken by mouth) plus trastuzumab delivered into the spinal fluid, to treat breast cancer that has spread to the leptomeninges (lining around the brain/spinal cord). It may help reduce cancer activity in the spinal fluid and improve symptoms.
BordeauxAges 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+ - NCT06016387RecruitingPhase 2
Drug combo with radiation for HER2+ breast cancer spread to spinal lining
This trial tests a combination of three targeted drugs (tucatinib, trastuzumab, and capecitabine) along with radiation to the brain or spine for people whose HER2-positive breast cancer has spread to the lining of the brain or spinal cord. The goal is to see if this treatment is safe and effective.
Ottawa, OntarioAges 18 years+ - NCT06008275RecruitingEarly Phase 1
Neratinib and ruxolitinib for metastatic triple-negative breast cancer
This early-phase trial tests a combination of two targeted drugs, neratinib and ruxolitinib, for people with metastatic triple-negative breast cancer who have already had standard chemotherapy. The goal is to see if the combination is safe and effective.
Dallas, TexasAges 18 years+ - NCT06027996Recruiting
Melodi Matrix in breast reconstruction
This trial tests a new mesh-like device called Melodi Matrix to support breast reconstruction after mastectomy. It may help women who are planning immediate two-stage implant reconstruction after removing one or both breasts.
Palo Alto, CaliforniaAges 22 years+ - NCT05974150Recruiting
Remote symptom monitoring for several blood and cancer types
This study checks how well remote (at-home) symptom check-ins work for people with certain cancers. It may help patients and clinicians spot problems earlier and improve day-to-day care during treatment and beyond.
