Filter by:HER2-low Breast cancer (BC) has emerged as a new subtype of BC with distinct clinical, pathological, and prognostic features. Little is known about the prevalence of the HER2-low subtype in HER2-negative patients, and previous reports showed variations in the criteria used to define the HER2-low subtype. Besides, data on the clinical features and prognosis of HER2-low patients are limited, and it is still unclear whether HER2-low BC has a prognostic value. Identifying the prevalence and clinical features of HER2-low BC can help establish a more accurate and reproducible definition of HER2-low BC. In the Gulf Cooperation Council (GCC) region, BC is the most common malignancy in women and still poses a significant burden on healthcare resource utilization, moreover, there is only one record for reimbursed HER2 IHC status, categorized as HER2-positive and HER2-negative. It is important to understand the prevalence, clinical features, and outcomes of HER2-low in BC patients from the GCC In this retrospective, non-interventional, multicenter study, the aim to describe the prevalence of HER2-low BC among the current HER2-negative BC population using rescored HER2 IHC samples. The local treatment patterns and the outcomes will be analyzed using the information abstracted from the corresponding medical chart review. The study will cover the GCC region countries (United Arab Emirates [UAE], Saudi Arabia, Qatar, Kuwait, and Oman)
This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks). Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue. The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy. Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.
Single arm, prospective, exploratory clinical study of Disitamab Vedotin combined with Fruquintinib for advanced colorectal cancer with HER2 expression or mutation that has received at least two standard treatment failures
The goal of this observational study is to learn about in describe treatment pattern and clinical outcomes in patients with HER2-overexpressed advanced solid tumors after progression of first-line standard therapy. The main questions it aims to answer are: - To evaluate the real-world safety and efficacy of Disitamab Vedotin in second-line and beyond treatment of advanced solid tumors with HER2 overexpression - To describe the treatment pattern and clinical outcomes of patients with advanced gastric cancer with HER2 overexpression in real world Settings after the failure of first-line standard therapy.
Preoperative systemic treatment can make patients getting more opportunity for breast-conserving surgery, down-staging and new drugs developing. It is particularly common in human epidermal growth factor receptor 2 (HER2)-over expressing subtype for as high as 40%~60% pCR rate of such a population. Even though, in NSABP B18/27 trials, it had been proved that PST could not improve either disease-free survival (DFS) or overall survival (OS) comparing with postoperatively systemic treatment in total population. We designed a real-world study to investigate the prognosis of anti-HER2 treatment combined with chemotherapy preoperatively versus postoperatively in HER2-positive early breast cancer
Prognostic assessment after preoperative systemic therapy (PST) plays a vital role in breast cancer patients. The clinical-pathologic staging system incorporating estrogen receptor (ER)-negative disease and nuclear grade 3 tumor pathology (CPS+EG staging system) can effectively predict prognosis after PST. The Neo-Bioscore has been developed by the incorporation of the human epidermal growth factor receptor 2 (HER2) status into the CPS+EG staging system. But in a real world in China, the both staging systems had limits because of trastuzumab administration varied a lot in China from the United States. This retrospective study will validate CPS+EG and Neo-Bioscore system and explored a modified Neo-Bioscore system in multiple centers.
To seek the efficacy signals of trastuzumab in combination with chemotherapy in pretreated patients of HER2 positive, relapse or metastatic carcinoma of digestive system as response rate (RR) determined by the Investigator using RECIST 1.1, and provide evidence for phase III clinical trial.
The purpose of this study is to determine whether lucitanib is safe and effective in the treatment of patients with FGF aberrant metastatic breast cancer, as well as in the treatment of patients with biomarker negative (FGF non-aberrant) metastatic breast cancer.
In case of gastric cancer, the incidence of HER-2 positivity (2+, 3+ on IHC and/or FISH (+)) is reported as similar as that of breast cancer, that is 22% of all cases. A recent ToGA Trial, phase III trial comparing trastuzumab combined with chemotherapy (fluoropyrimidine+cisplatin) versus chemotherapy alone in chemotherapy-naïve HER-2 (+) gastric cancer shows the significant benefit of using trastuzumab in terms of overall survival and progression-free survival. It provides the clinical evidence of HER-2 as a reasonable and potential therapeutic target in gastric cancer. Nowadays, lapatinib, HER-1 and HER-2 dual inhibitor, is also testing under the clinical trial in gastric cancer. In preclinical study, PF-00299804 is highly active in HER-2 amplified gastric cancer cell lines.(SNU preclinical data) So, we plan this phase II trial of PF-00299804 monotherapy in patients with HER-2 positive advance gastric cancer after failure of at least one chemotherapy regimen.
