Filter by:This Phase III trial compares the recurrence-free interval (RFI) among patients with early-stage, low risk HER2+ breast cancer who undergo breast conserving surgery and receive HER2-directed therapy, and are randomized to not receive adjuvant breast radiotherapy versus those who are randomized to receive adjuvant radiotherapy per the standard of care.
Trastuzumab and pertuzumab based regimen are the standard of care for patients with human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (MBC), significantly improving survival outcomes. However, an unmet medical need remain for patients with disease refractoriness and recurrence. Interestingly, HER2 over-expression is associated with upregulation of vascular endothelial growth factor (VEGF) in cancer cells in vitro and in vivo. Preclinical studies indicated that VEGF expression is positively regulated by HER2 signaling. In the clinical setting, HER2 over-expression correlated significantly with VEGF over- expression in samples from patients with breast cancer. There is, therefore, a biologic rationale for targeting both HER2 and VEGF pathways in patients with HER2-positive breast cancer. PURPOSE: The hypothesis that justifies this research is that the addition of Thero2-01S22 as add-on therapy on top of first line anti-HER2 targeted treatment will improve the efficacy of anti-HER2 targeted containing regimen at the metastatic setting for breast cancer.
Adjuvant radiotherapy is the standard treatment for early breast cancer after breast conserving surgery. Molecular subtypes was significantly associated with the risk of local recurrence of breast cancer. Nguyen et al found that the overall 5-year cumulative incidence of local recurrence was 0.8% for luminal A, 1.5% for luminal B, 8.4% for HER2 positive, and 7.1% for triple negative breast cancer after lumpectomy and radiotherapy. Her2 positive and triple negative breast cancers may be inherently radioresistant. Therefore, for HER2 positive and triple negative breast cancer with high local recurrence and radiation resistance, proton combined with carbon ion is proposed after breast conserving surgery.
This is a single-arm, phase II trial evaluating the efficacy and safety of SHR-A1811 combined with pyrotinib maleate in Stage II-III HER2-positive breast cancer. Subjects will receive the neoadjuvant therapy of SHR-A1811 and pyrotinib for six cycles, and then undergo surgery within 4 weeks after neoadjuvant therapy. Efficacy will be assessed every 2 cycles.
The purpose of this study is to describe the demographic and clinical profiles of patients with early-stage HER2+ breast cancer treated with neratinib as an extended adjuvant therapy as part of the Early Access Program (EAP) in Europe.
This will be a Phase 1, multicenter, open-label trial to evaluate the safety, tolerability, PK and efficacy of ZN-A-1041 as a monotherapy or in combination in patients with HER2-positive advanced solid tumors with or without brain metastases. The study will consist of three phases: Phase 1a (dose escalation with ZN-A-1041 monotherapy), Phase 1b (dose escalation with ZN-A-1041 combination therapy) and Phase 1c (dose expansion with ZN-A-1041 combination therapy).
The purpose of this study is to establish a prospective, single-center platform research based on clinical subtypes to explore precision neoadjuvant therapy in patients with operable breast cancer who met the indications for neoadjuvant chemotherapy and by the update of basic translational research in the center, especially the refinement of typing, the discovery of new targets and the development of novel targeted drugs, verified the effectiveness of new targeted drugs in neoadjuvant therapy.
Pyrotinib is currently being investigated in both registration studies and investigator-initiated studies in the neoadjuvant and adjuvant setting for HER2-positive breast cancer, all of which are RCTs, but randomized clinical studies have selected specific populations in defined settings, which may differ from the actual clinical setting. Given the limited real-world data on pyrotinib, real-world studies focusing on neoadjuvant therapy have not been reported. At present, we hope to collect the data of neoadjuvant therapy for HER2-positive breast cancer patients who have been prescribed pyrotinib, and explore the efficacy and safety of pyrotinib-based neoadjuvant therapy for HER2-positive early or locally advanced breast cancer patients; exploratory analysis to explore the correlation between TMB levels and pCR rate of neoadjuvant therapy in HER2-positive breast cancer patients, and the effect of pyrotinib-based neoadjuvant therapy on intestinal flora.
HER2+ breast and gastric cancer patients' survival is significantly improved by trastuzumab alone or in combination with chemotherapy. However, many patients remain uncured and develop resistance to trastuzumab resulting in relapse or progression of the disease. BI-1607, a human immunoglobulin G1 (IgG1) monoclonal antibody (mAb) targets CD32b (Fc Gamma Receptor IIB), it is intended to enhance the efficacy and overcome resistance to existing cancer treatments such as trastuzumab. This is a Phase 1/2a, first-in-human, open-label, multicenter, dose-escalation, consecutive-cohort study of BI-1607 in combination with trastuzumab in subjects with HER2+ advanced solid tumors whose tumor has progressed after standard therapy.
This research study will evaluate how well brain metastases associated with HER-2 positive breast cancer can be controlled using a type of radiation known as stereotactic radiosurgery (SRS) when combined with three therapeutic agents, tucatinib, capecitabine, and trastuzumab. The combined use of SRS with the three drugs is considered investigational.
