Active clinical trials for "Breast Neoplasms"

This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).

Studies on postoperative adjuvant albumin paclitaxel in domestic breast cancer patients are less reported, especially in large samples, and more studies focus more on the safety and tolerability of albumin paclitaxel use. Head-to-head studies of white violet and docetaxel are not supported by data at this time, but some studies have shown that docetaxel-induced long-term Other adverse effects such as myelosuppression, hepatotoxicity and hypersensitivity reactions can have a serious impact on quality of life. Therefore, this study aims to analyse the efficacy and safety of albumin paclitaxel and docetaxel in the adjuvant treatment of breast cancer in a large randomized controlled trial, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.

This is a multicenter, randomized, double-blind, placebo-controlled Phase III clinical study evaluating the efficacy and safety of FCN-437c in combination with letrozole or anastrozole ± Goserelin versus placebo combined with letrozole or anastrozole ± Goserelin in women with first-line advanced breast cancer in HR+ and HER2-.

This study is a multicenter, randomized, phase 3 clinical trial in patients with breast cancer, randomizing radiotherapy group (postmastectomy radiation therapy (PMRT)/whole breast irradiation plus regional radiotherapy (WBI+regional RT) versus and no PMRT/WBI alone group. This is a non-inferiority study aiming that there is no significant difference in the 7-year disease-free survival rate between the two groups.

This is an open label, multicenter, single arm phase II study to evaluate the efficacy and safety of ribociclib and ET in patients with locoregional recurrence of HR-positive, HER2-negative breast cancer.

The primary aim of this study is to investigate and test whether the use of combined indocyanine green (ICG) lymphography and ultra high frequency ultrasonography can correctly identify lymphatic vessels and venoles in close proximity to each other, for identification prior to lymphovenous anastomosis (LVA) surgery.

The objective of this study is to explore and evaluate the efficacy of tucidinostat combined with metronomic capecitabine in the treatment of metastatic triple-negative breast cancer.

This is a single-arm, open-label phase IV study of patients with advanced HR+/HER2- breast cancer who are treated first line with ribociclib and standard of care endocrine treatment according to SmPC.

Breast cancer is the second most common invasive malignancy and the leading cause of cancer-related mortality in women. Overexpression of human epidermal growth factor receptor 2 (HER2) is observed in approximately 20% of breast cancers. Trastuzumab provided patients with HER2 overexpressing breast cancer a better outcome than chemotherapy alone. Trastuzumab and pertuzumab exert part of their activity based on antibody-dependent cell-mediated cytotoxicity (ADCC), mediated by natural killer (NK) cells. Trastuzumab (Herceptin®) is a recombinant DNA-derived humanized monoclonal antibody that selectively binds with high affinity to the extracellular domain of the human epidermal growth factor receptor 2 (HER2). Inhibits the proliferation of human tumor cells that overexpress HER2 and to mediate antibody-dependent cellular cytotoxicity (ADCC). Pertuzumab (Perjeta®) is a fully humanized monoclonal antibody and, like trastuzumab, is directed against the extracellular domain of HER2. It differs from trastuzumab because they bind to different domains. Due to their distinct mechanisms of action, the combination of pertuzumab and trastuzumab, is hypothesized to have complementary roles in treating HER2-overexpressing diseases. Natural killer cells are lymphocytes arising from CD34+ hematopoietic progenitor cells in the bone marrow. NK cells are identified as CD3-, CD56+ lymphocytes. These cells were identified on the basis of their ability to lyse tumor cells without prior sensitization. NK function is also regulated by cytokines such as IL-2, IL-15, IL-12 and IL-18. Our hypothesis is that the effect of trastuzumab and pertuzumab can be improved by regulating the efficiency of the ADCC activity through the infusion of ex-vivo activated allogenic NK cells. Objetives: Primary: To assess the safety and the tolerability of NK-ACT and trastuzumab/pertuzumab when used in combination. Secondary: To evaluate the initial clinical activity of NK-ACT concomitant with trastuzumab/pertuzumab. Exploratory Objectives: In vivo human NK cell biology: To describe the mechanisms of action of the combination of ICTP and rastuzumab/pertuzumab. To assess the biomarkers that might act as indicators of the immunemodulatory effect and anti-tumor activity of the combination.

Cardiotoxicity is one of the most significant adverse effects in breast cancer patients treated with anthracyclines (a type of chemotherapy), so we propose to determine whether acute training (i.e., 24h before each chemotherapy session) could reduce the levels of a cardiac biomarker which measures muscle damage (NT-proBNP). Given the fact NT-proBNP attenuation has been observed with one session performed 24h before the first treatment, we propose to verify these findings in each cycle of doxorubicin analyzing how each type of exercise (aerobic, strength or combined aerobic + strength) may impact on anthracycline-induced cardiotoxicity, since this observation may be relevant considering the feasibility and low cost this implementation would represent in clinical practice.
