Pertuzumab, Trastuzumab, and Paclitaxel Albumin-Stabilized Nanoparticle Formulation in Treating Patients With HER2-Positive Advanced Breast Cancer

This phase II trial studies how well pertuzumab, trastuzumab, and paclitaxel albumin-stabilized nanoparticle formulation work in treating patients with human epidermal growth factor receptor (HER) 2-positive stage II-IV breast cancer. Monoclonal antibodies, such as pertuzumab and trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, work in different ways to kill tumor cells or stop them from growing. Giving pertuzumab and trastuzumab together with paclitaxel albumin-stabilized nanoparticle formulation may be a better way to block tumor growth.

Copper Cu 64-DOTA-Trastuzumab PET in Predicting Response to Treatment With Ado-Trastuzumab Emtansine in Patients With Metastatic HER2 Positive Breast Cancer

This pilot clinical trial studies how well copper Cu 64-tetra-azacyclododecanetetra-acetic acid (DOTA)-trastuzumab positron emission tomography (PET) works in predicting response to treatment with ado-trastuzumab emtansine in patients with human epidermal growth factor receptor 2 (HER2) positive breast cancer that has spread to other places in the body. Copper Cu 64-DOTA-trastuzumab is a chemotherapy drug (trastuzumab) attached to a radioactive substance. Diagnostic procedures using PET may allow scanners to take pictures of where the drug travels in the body and may help doctors identify which patients may benefit from treatment with ado-trastuzumab emtansine.

A Clinical Study of Neoadjuvant Treatment With TQB2102 for Injection for Human Epidermal Growth Factor Receptor 2 (HER2) Positive Breast Cancer

This is a randomized, open, positive drug control, multi center phase III study. Through the evaluation of tpCR, bpCR, ORR, EFS, IDFS, OS, AEs and other indicators, it proves the effectiveness and safety of TQB2102 for injection versus Active Comparator in the neoadjuvant treatment of HER2 positive breast cancer patients. About 544 HER2 positive early or locally advanced breast cancer patients will be randomly assigned to TQB2102 treatment group (test group) or Docetaxel combined with Carboplatin, Trastuzumab, and Pertuzumab (TCbHP) (Active Comparator) in a 1:1 ratio. The subjects in the test group will receive 8 cycles of study drug treatment, and the subjects in the control group will receive 6 cycles of study drug treatment, followed by surgery for breast cancer, and disease recurrence visit and survival visit after surgery.

Low-Dose Apatinib Plus Chemotherapy in ADC-Pretreated HER2-Positive and HER2-Low Advanced Breast Cancer

This is a single-arm, open-label, phase 2 clinical trial using a stratified Simon minimax two-stage design. The study aims to evaluate the efficacy and safety of low-dose apatinib (250 mg daily) combined with physician-selected single-agent chemotherapy (TPC, capecitabine preferred) in patients with HER2-positive or HER2-low advanced/metastatic breast cancer who progressed after prior ADC therapy (T-DXd or SHR-A1811). Patients are stratified by HER2 status, HR status, lines of prior ADC therapy, and metastasis sites. Approximately 56 patients will be enrolled. The primary endpoint is objective response rate (ORR). Secondary endpoints include PFS1, PFS2, TTP, safety, and OS.

SMP-656 for HER2-Positive Advanced Breast Cancer

The goal of this clinical trial is to learn if single-agent SMP-656 works to treat patients with HER2-positive locally advanced or metastatic breast cancer who have progressed after prior HER2-targeted topoisomerase inhibitor antibody-drug conjugate (ADC) treatment. It will also evaluate the safety of SMP-656 and identify the optimal dose for future trials. The main questions it aims to answer are: What is the objective tumor response rate (DOR, PFS, DCR, OS) of two different dose regimens of intravenous SMP-656? What are the side effects and safety risks of these two SMP-656 dose regimens? Which dose level achieves the best balance of anti-cancer activity and tolerability? This is a randomized, open-label, dose-optimization Phase II clinical trial. Participants will be randomly assigned 1:1 to receive one of two fixed doses of SMP-656 given intravenously once every 3 weeks. Participants will: Complete screening tests within 28 days before the first SMP-656 infusion to confirm eligibility Receive study treatment every 3 weeks until cancer progression, intolerable side effects, withdrawal, or other stopping criteria Have regular tumor imaging scans, physical exams, vital sign checks, and blood tests to monitor tumor response and safety Attend a safety follow-up visit 30 days after the last dose of SMP-656 Complete longer-term survival follow-up after the 30-day safety check Provide optional blood and tumor tissue samples for additional research studies

Kadcyla And Neratinib for Interception of HER2+ Breast Cancer With Molecular Residual Disease

This is a Phase 2 study for patients with resected Stage I-III HER2+ breast cancer with detected molecular residual disease (MRD+) following standard neoadjuvant and locoregional therapy delivered with curative intent. In this study Patients will be treated with neratinib in addition to their standard T-DM1 adjuvant therapy. Neratinib will be administered orally at a dose of 160 mg daily for up to 12 months, or until the time of clinical recurrence, discontinuation due to toxicity, or withdrawal of consent. This study will have two stages, stage 1 would enroll up to 8 participants to clear the Minimal Residual Disease (MRD) and Stage 2 will enroll up to 5 participants. The purpose of this study is to determine if this study population would have a better outcome from adding neratinib to their standard T-DM1 adjuvant therapy.

TVB-2640 and Trastuzumab With Paclitaxel or Endocrine Therapy for Treatment of HER2 Positive Metastatic Breast Cancer

This phase II trial studies how well FASN inhibitor TVB-2640, paclitaxel, and trastuzumab work in treating patients with HER2 positive breast cancer that has spread to other places in the body (metastatic). FASN inhibitor TVB-2640 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Trastuzumab is a form of targeted therapy because it attaches itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Estrogen can cause the growth of breast cancer cells. Drugs used in endocrine therapy either lower the amount of estrogen made by the body or blocks the use of estrogen by the tumor cells. This may help stop the growth of tumor cells that need estrogen to grow. Giving FASN inhibitor TVB-2640 and trastuzumab in combination with paclitaxel or endocrine therapy may help control the disease in patients with HER2 positive breast cancer.
