NCT06595563
ZEPHIR-02 is a multicentre, open-label phase II study that will enroll subjects with HER2-positive advanced/metastatic breast cancer (mBC) who have experienced disease progression under trastuzumab deruxtecan (T-DXd) in the metastatic setting. All subjects will undergo baseline biopsy, blood collection, FDG-PET/CT and 89Zr-trastuzumab PET/CT (HER2-PET/CT) and will be classified as HER2-PET/CT positive or negative, as previously described in the ZEPHIR trial. Focusing on a central visual "patient-based" classification that captures the entire disease burden, a side-by-side display will be used, comparing baseline FDG-PET/CT (which identifies all FDG-positive metastases regardless of their HER2-imaging status) and HER2-PET/CT. Subjects will be categorized into two HER2-PET/CT patterns (positive vs. negative) based on proportion of FDG-avid tumor load with significant 89Zr-trastuzumab uptake. Subjects classified as "positive" will receive T-DM1 as monotherapy, IV 3.6mg/kg every 3 weeks (21 days +- 3 days) until disease progression, unacceptable toxicity or request of the subject to withdraw from the study. FDG-PET/CT will be performed before cycle 2 of T-DM1 will serve as a research tool to correlate metabolic changes with clinical outcomes. Other FDG-PET/CT will be performed before cycle 4 of T-DM1 for assessment of response. Subjects who demonstrate a partial or complete response (responders) will continue treatment with T-DM1. Subjects who exhibit stable disease or disease progression (non-responders) will discontinue study treatment and enter the survival follow-up period. For responders, subsequent metabolic evaluations will be performed every 3 months, with FDG-PET/CT. Treatment response will be assessed according to metabolic response. For these subjects, mandatory blood samples will be obtained at all metabolic reassessments. Subjects with HER2-PET/CT classified as "negative" will receive treatment of physician's choice (TPC) as per the best local clinical practice and be out of the study. All enrolled subjects will undergo a mandatory biopsy during the pre-treatment period. The study also includes mandatory translational procedures (i.e. collection of tumour biopsy during pre-treatment period and blood samples at pre-specified time points) for exploratory molecular analyses.
NCT03417544
This research study is studying a drug called atezolizumab as a possible treatment HER2-positive metastatic breast cancer (MBC) that has spread to the brain. The names of the study drugs involved in this study are: * Atezolizumab * Pertuzumab * Trastuzumab
NCT06551116
This study will assess whether a quantitative, HER2 assay can accurately and reliably discriminate between responders and non-responders among patients with HER2 IHCI+ metastatic breast cancer who are receiving T-Dxd.
NCT06625775
First in human study to evaluate the safety, tolerability, and pharmacokinetics (PK) of BBO-10203, a PI3Kα:RAS breaker, alone and in combination with other anti-cancer agents in patients with advanced solid tumors.
NCT05230810
Phase IB/II clinical trial of Alpelisb and Tucatinib in patients with PIK3CA-Mutant HER2-positive metastatic breast cancer.
NCT05800275
The goal of this clinical trial is to evaluate the efficacy of tucatinib and capecitabine in combination with intrathecal trastuzumab on overall survival rate at 12 months in HER2-positive metastatic breast cancer (MBC) patients with proven leptomeningeal evolution and requiring intrathecal therapy.
NCT05555251
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.
NCT06305702
A multicenter real-world study was conducted to gather clinicopathological data from patients with HER2-positive metastatic breast cancer who were treated with inetetamab between 2022 and 2023. The study aimed to estimate the progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) associated with inetetamab therapy.
NCT05042791
This study evaluates the efficacy and safety of SRT combined with pyrotinib and capecitabine in the treatment of patients with HER2-positive advanced breast cancer patients with brain metastases.
NCT04778982
This is an open-label, multicenter, dose-escalation and parallel-group expansion Phase II clinical trial to evaluate the efficacy, safety and tolerability of KN026 in combination with palbociclib and fulvestrant in women or male with HER2-positive metastatic breast cancer .The subjects will receive 20 mg/kg IV Q2W+ palbociclib 100/125 mg/day orally+/-Fulvestrant 500 mg IM until progressive disease, unacceptable toxicity or death.
NCT05188495
Currently, data of the efficacy of trastuzumab plus pertuzumab and chemotherapy is limited in the HER2 positive metastatic breast cancer patients previously treated with trastuzumab during (neo)adjuvant and metastatic setting, and results are not consistent.The main purpose of this study is to evaluate the 6-month progression free survival(PFS) of trastuzumab(Henlius®) combined with Pertuzumab(Perjeta®) and Chemotherapy as first to third line therapy in Chinese patients with HER2 positive metastatic breast cancer who received trastuzumab previously.Primary Endpoint is 6-month Progression-free survival (PFS);Secondary Endpoint(s) include Progression-free survival (PFS) Overall Survival (OS);Objective Response Rate(ORR);
NCT03979339
This is a prospective interventional single-site research with a collection of biological samples. The primary objective of the trial is to assess the ability of the "new technology" to isolating circulating tumor cells (CTC) in selected cancer patients. Five groups will be constitued: at first the Group 0: Healthy volunteers included for the spike-in test; and then the four groups, Group1: Metastatic HER2-positive breast cancer; Group 2: Advanced CA-125 positive ovarian cancer; Group 3: Metastatic PSA-positive castrate-resistant prostate cancer; Group 4: Healthy volunteers included as control). In each group, the percentage of cases with identified circulating tumor cells will be estimated.
NCT02605915
This is a Phase Ib, open-label, two-stage study with two active regimens in each stage designed to evaluate the safety and tolerability of combination treatment with atezolizumab, trastuzumab, and pertuzumab (with and without docetaxel) or atezolizumab and trastuzumab emtansine in participants with human epidermal growth factor receptor 2 (HER2) positive metastatic breast cancer (MBC) and locally advanced early breast cancer (EBC), and atezolizumab with doxorubicin and cyclophosphamide in HER2-negative breast cancer.
