HER2 Molecular Imaging With 89Zr-trastuzumab PET/CT as a Predictive Biomarker for Antibody-drug Conjugate Sequencing in Patients With Advanced HER2-positive Breast Cancer

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.

Study of Cardiopulmonary Exercise Testing in Women Who Have HER2-Positive Breast Cancer With Mild Cardiotoxicity

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.

Discontinuation of Maintenance HER-2 Directed Therapy in Long-Term Survivors of Metastatic HER-2 Positive Breast Cancer

The purpose of this preliminary research study is to see if patients discontinuing maintenance Herceptin and/or other anti-HER-2 treatments with monitoring in addition to radiologic imaging and routine blood work will stay in complete radiological remission and to determine how long patients are able to stay in complete radiological remission without treatment.

ELVN-002 in HER2 Mutant Non-Small Cell Lung Cancer

The goal of this clinical trial is to test ELVN-002 in people with cancers that have an abnormal HER2 gene. The main question the trial aims to answer is if ELVN-002 is safe and tolerable at different doses. A second main question is to evaluate the concentration of ELVN-002 in the blood at different doses and to see how this correlates with safety and see how the concentration of drug changes over time. The third main question is to see if ELVN-002 works to shrink cancers that have HER2 genetic abnormalities, particularly non-small cell lung cancer.

Dose-Expansion Modular Study To Explore the Safety, Tolerability, and Anti-tumor Activity of HER3- DXd Monotherapy and Combinations in Patients With Inoperable Advanced Breast Cancer (ABC) After Progression on T-DXd

ICARUS-BREAST02 is an open-label, multicenter, phase 1b/2, platform study that aims to evaluate the safety, tolerability, and efficacy of HER3-DXd monotherapy and in combination with other anti-cancer agents in patients with ABC. The first 2 modules will evaluate: i. safety and efficacy of HER3-DXd with olaparib in patients with HER2-low and HER2-positive ABC progressed on T-DXd (Module 1) and HER3-DXd monotherapy in patients with HER2-low ABC progressed on T-DXd (Module 0). The main objective of Part 1 is to assess the safety and tolerability of HER3-DXd monotherapy and combination and to determine the recommended phase 2 dose (RP2D) of the combination containing HER3-DXd. The main objective of Part 2 is to assess the efficacy of study therapies in each module based on investigator assessment as evaluated by the objective response rate (ORR) at 6 months.

Disitamab Vedotin + Pyrotinib Versus THP in the First-line Treatment for HER2+ Advanced Breast Cancer Clinical Trial

The goal of this multicentre, randomized, double-blind controlled, phase III clinical trial is to compare the efficacy and safety of disitamab vedotin in combination with pyrotinib versus the standard first-line treatment of paclitaxel in combination with trastuzumab and pertuzumab (THP) for newly diagnosed recurrent/metastatic Human epidermal growth factor receptor 2 (HER2) positive advanced breast cancer, and to explore the impact of biomarkers on clinical efficacy and safety. The main questions it aims to answer are: * Analyse the efficacy and safety of disitamab vedotin in combination with pyrotinib versus the standard first-line treatment of THP. * Explore the impact of biomarkers on clinical efficacy and safety of the combination of disitamab vedotin in combination with pyrotinib treatment. Participants in the experimental group will receive disitamab vedotin in combination with pyrotinib for 6-8 cycles (each cycle lasting 28 days), followed by maintenance treatment with trastuzumab in combination with pyrotinib. Participants in the control group will receive paclitaxel in combination with trastuzumab and pertuzumab for 6-8 cycles (each cycle lasting 21 days), followed by maintenance treatment with trastuzumab and pertuzumab. Researchers will compare disitamab vedotin in combination with pyrotinib versus the standard first-line treatment of paclitaxel in combination with trastuzumab and pertuzumab to see if disitamab vedotin in combination with pyrotinib could be a new option for first-line treatment of HER2-positive metastatic breast cancer.
