Deescalation of Endocrine Therapy Duration in Women With HR+ HER2- Breast Cancer at Very Low Risk...
Breast CancerHormone therapy is recommended for five years in all patients with hormone receptor-positive breast cancer, but there is no consensus on its duration in low-risk tumours and especially in postmenopausal women. Adjuvant endocrine therapy (ET) is associated with substantial side effects and long-term decreased quality of life. Moreover, while it has been shown that ET provides a real benefit in reducing the relapse rate over time, the deterioration in quality of life may also have a negative effect on patient adherence to treatment. It is therefore important to offer treatment to women with low-risk cancer less intensive treatment strategies. If recent trials tested longer durations as compared to 5 years for high-risk cancers, older trials have tested shorter durations. The 5-year duration appeared at that time as the gold standard because of optimal benefit-risk ratios of tamoxifen among high-risk patients. However shorter treatments of 2-3 years were already associated with substantial benefits and may be enough for very low risk patients.
Secondary BRain Metastases Prevention After Isolated Intracranial Progression on Trastuzumab/Pertuzumab...
Brain MetastasesHuman Epidermal Growth Factor 2 Positive Carcinoma of Breast1 morePatients with advanced HER2+ breast cancer on maintenance trastuzumab/pertuzumab or T-DM1 with 1st or 2nd intracranial disease event (brain metastases) and stable extracranial disease will be enrolled. They will receive local therapy with stereotactic radiosurgery ± surgical resection if indicated followed by enrollment. Patients will continue standard of care trastuzumab/pertuzumab or T-DM1 with the addition of tucatinib. Hormone receptor positive patients requiring endocrine therapy should continue. Study treatment will continue until disease progression or intolerable side effects. Patients on trial with extracranial disease progression with stable intracranial disease should continue tucatinib into next line of therapy.
A Phase II Study of Chiauranib in Combine With Capecitabine in TNBC
Triple-negative Breast CancerThis study is to evaluate the preliminary efficacy and safety of chiauranib in combine with capecitabine in advanced triple-negative breast cancer failed to prior anthracyclines and taxanes therapy
EGFR/B7H3 CAR-T on Lung Cancer and Triple Negative Breast Cancer
EGFR/ B7H3-positive Advanced Lung CancerEGFR/ B7H3-positive Advanced Triple-negative Breast CancerThis study is a single-arm, open, exploratory clinical study to evaluate the safety and efficacy of EGFR/B7H3 CAR-T in patients with EGFR/ B7H3-positive advanced solid tumors (lung cancer and triple-negative breast cancer)
A Phase Ib Study of GB491 Plus Letrozole in Patients With Advanced Breast Cancer
Advanced Breast CancerGB491-005 is a multicenter, open-label, phase Ib Clinical Trial study to evaluate the safety, pharmacokinetic (PK), pharmacodynamic (PD) activity, and preliminary anti-tumor activity of GB491 in combination with Letrozole in Previously Untreated Patients with HR-positive, HER2-negative Advanced Breast Cancer
Neoadjuvant Treatment of Locally-advanced Breast Cancer Patients With Ribociclib and Letrozole
Breast CancerHER2-negative Breast Cancer4 morePatients with locally advanced (stage III) breast cancer (LABC) are characterized by a significantly worse prognosis compared to patients with primarily operable breast cancer. While neoadjuvant chemotherapy has been the first choice in this situation for several decades, recent evidence suggests that some patients may experience an extraordinary effect from neoadjuvant endocrine treatments involving aromatase inhibitors as monotherapy or in modern drug combinations.Selected LABC patients admitted for treatment will be offered combination therapy including letrozole and ribociclib. The overall goal of the project is to improve understanding of tumor responses and resistance in patients suffering from ER-positive/HER-2 negative locally advanced breast cancer, focusing on the role of the immune system including the gut microbiome.
A Study of Tucatinib or Placebo With Trastuzumab and Pertuzumab for Metastatic HER2+ Breast Cancer...
HER2 Positive Breast CancerThis study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.
Moxifloxacin in Adjuvant Treatment of Patients With Operable Breast Cancer
Breast CancerThe primary objective of this study is to compare disease-free survival (DFS) of patients with operable breast cancer randomised to treatment with standard adjuvant chemotherapy plus moxifloxacin or placebo.
Aesthetic Outcomes of Oncoplastic Breast Surgery for Breast Cancer in the Upper Inner Quadrant
Oncoplastic Breast SurgeryBreast Cancer1 moreOncoplastic breast surgery, combining oncological resection with plastic surgical techniques, has emerged as an important surgical strategy to optimize conventional breast-conserving surgery. The upper inner quadrant is one of the most difficult and challenging tumor locations for surgeons to perform oncoplastic breast surgery. There is a pressing need to develop a simple and effective oncoplastic surgical technique to cope with the unfavorable anatomy and location of tumors in the UIQ. Here, we present a new oncoplastic volume displacement technique for UIQ using the DSG flap. This trial was design to estimate the aesthetic outcomes of an oncoplastic technique using a droplet-shaped glandular flap for breast cancer in the upper inner quadrant.
Testosterone & Tamoxifen Trial
Male Breast CancerThis is a concise single arm, feasibility study, which will be executed in the University Medical Center Groningen, The Netherlands. Male patients with metastatic BC (n=6) are eligible for this study after at least 1 line of conventional endocrine therapy.
