Filter by:This study aims to identify HER2-positive early-stage breast cancer patients who could benefit from neoadjuvant treatment using PHESGOâ„¢ (pertuzumab and trastuzumab) without chemotherapy. The approach involves utilizing specific biomarkers (HR and HER2 IHC status) to select participants whose tumors strongly rely on the HER2 pathway, potentially benefiting from a HER2-targeted approach without chemotherapy concurrently.
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.
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.
RATIONALE: According to previous results from PHARE study, a subgroup of patients with low-risk cancer (< 3 cm) without axillary lymph node involvement or small (< 2 cm) with minimal lymph node involvement (1 positive node) presented low risk of recurrence. Maintaining chemotherapy in this subgroup could cause toxicity and it is not yet known whether giving trastuzumab as monotherapy in neoadjuvant setting is as effective as giving trastuzumab combined with paclitaxel in patients with low risk early breast cancer. PURPOSE: This randomized phase III trial is studying trastuzumab as monotherapy in neoadjuvant setting to see if this treatment regimen is as efficient compared to trastuzumab combination with paclitaxel chemotherapy in treating women with low risk (tumor size< 3 cm, N0) early breast cancer.
This is a study of DP303c in patients with HER2-positive advanced breast cancer.
This is a prospective study on the prevention of Neratinib-related diarrhea in a Chinese population, exploring the best options for reducing the incidence of neratinib-related diarrhea through either pharmacologic intervention (prophylactic antidiarrheal therapy) or non-pharmacologic intervention (dose escalation program).
This is a single-arm exploratory study to explore the effect of RC48 in HER2-positive neoadjuvant therapy and evaluate the non-inferiority of RC48 by comparing the latest reported data of T-DM1 in neoadjuvant therapy.
This is a prospective, multicenter, cohort study aiming to explore the cardiotoxicity of targeted therapy for HER-2 positive breast cancer patients who lives in high altitude area. One hundred and thirty two HER-2 positive breast cancer patients who will receive neoadjuvant, adjuvant, or palliative targeted therapy will be enrolled. The cardiotoxicity of targeted therapy will be observed and recorded during the treatment and one year after the end of treatment. The subjects will be stratified by age, baseline cardiac risk factors, and anthracyclines.
This is a prospective, randomized, 2-arm, Phrase 2, superiority and multicenter study to compare the efficiency of Anti-HER2 TKI versus Pertuzumab in Combination With Dose-dense Trastuzumab and Taxane in HER2-positive breast cancer patients with active refractory brain metastases.
The purpose of this study is to assess the efficacy and safety of pyrotinib combined with trastuzumab and abraxane in HER2-positive MBC with brain metastasis.
