Filter by:The study is a single arm, nonrandomized phase II prospective study, with the goal of investigating the role of screening brain MRIs in neurologically asymptomatic patients with metastatic breast cancer.
This study is designed to assess the safety and preliminary activity of SBT6050 in combination with trastuzumab deruxtecan (Part 1) or tucatinib plus trastuzumab +/- capecitabine (Part 2). Participants will be enrolled into each Arm based on cancer diagnosis and prior therapies.
This is a prospective Single-arm Study to Investigate the Efficacy and Safety of Neoadjuvant treatment with trastuzumab and pyrotinib plus palbociclib and fulvestrant in HER2-positive, ER-positive breast cancer.
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.
The purpose of this study is to find out how much oxygen is used during a cardiopulmonary exercise test (CPET) in women who have mild cardiotoxicity after standard treatment for HER2-positive breast cancer, and to see whether the results of this test can be used to predict how well participants' heart and lungs will work if they continue to receive this kind of treatment.
The treatment of patients with HER2 positive early breast cancer has continuously improved over the last decades. Up to now both, trastuzumab and pertuzumab are approved in combination with chemotherapy (CTX) not only for the adjuvant but also for the neoadjuvant treatment of early breast cancer patients. A high pCR rate in the neoadjuvant setting was shown in several trials and observational studies with CTX+ trastuzumab and with CTX+ pertuzumab. The efficacy is dependent on a variety of mechanisms including the blocking of the important PI3K/Akt and MAPK pathways, and ADCC (antibody dependent cellular toxicity). Recently the biosimilar Ontruzant® (SB3) has been introduced into the treatment of HER2 positive breast cancer as a biosimilar. Efficacy and toxicity have been shown to be equivalent to the first approved antibody, however, data from the real-world setting have not been published like it has for the originally approved antibody. Therefore, the aim of this study is to establish safety and efficacy for Ontruzant® in the real world setting. Patients can be included if they are treated with Ontruzant® in the neoadjuvant setting. Additionally, the study will be accompanied by a comprehensive immune monitoring program and biomarker program to explore immune oncology potential for the neoadjuvant treatment.
The purpose of this study is to learn whether clinical response (the amount a tumor shrinks based on imaging or tumor measurements obtained by physical exam) predicts pathologic response (the amount of tumor remaining when surgery is performed) in participants with breast cancer who are receiving chemotherapy prior to surgery.
The introduction of trastuzumab for the treatment of patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer has had a major impact upon cancer outcomes. However, cardiac toxicity remains a substantial concern. Conventionally, this toxicity has been considered as a transient and reversible phenomenon occurring in the immediate peri-treatment period in around 20% of patients. Current guidelines recommend monitoring heart function during treatment and at completion. Recent registry data suggest that trastuzumab-related cardiotoxicity may also manifest in the longer-term. The nature and longer-term prevalence of left ventricular dysfunction with HER2 positive breast cancer treated with trastuzumab is unclear. The aim of this project is to define the prevalence of left ventricular dysfunction late after completion of trastuzumab therapy.
This is a phase II open-label, multicenter trial assessing the efficacy of combination regimen"Dalpiciclib plus Exemestane plus trastuzumab plus pyrotinib"in early triple positive breast cancer patients.
Phase II unicentric randomized trial which will include early HER2 positive breast cancer patients, candidate to neoadjuvant therapy with trastuzumab and pertuzumab. Circulating tumor cells will be collected at neoadjuvant therapy baseline. Patients with pathological complete response will be randomized in 1:1 ratio for adjuvant trastuzumab (arm A) versus trastuzumab + pertuzumab (arm B) in a two factorial design: group A, with HER2 positive CTCs and group B, with HER2 negative/absent CTCs.
