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.

Safety of Withdrawal of Pharmacological Treatment for Recovered HER2 Targeted Therapy Related Cardiac Dysfunction

Breast cancer is the most common cancer in the United Kingdom (UK), but improvements in treatment mean 3 in 4 people survive for more than 10 years. Many people receive treatments called human epidermal growth factor receptor 2 (HER2) targeted therapies for their breast cancer, however these can affect heart function. This 'cardiotoxicity' is generally temporary and mild, but patients receive drugs to help their heart recover. Currently it is not known how long patients should receive these treatments. Patients with other types of heart failure are treated lifelong, but this may not be necessary here as the damaging cancer drugs have stopped. Taking drugs for many years can have an impact on people's quality of life, particularly for young patients. It is therefore important to understand the best treatment length. The investigators will study people whose heart function has recovered after HER2 therapy heart problems and are not at high risk for heart disease. The investigators will carefully stop their heart drugs whilst monitoring them closely with special heart scans and blood tests to detect problems early. The investigators will also study how patients are currently treated using national data. The results of this study will help doctors better guide breast cancer survivors about treatment of heart damage from HER2 cancer therapies.

HER2 Directed Dendritic Cell Vaccine During Neoadjuvant Therapy of HER2+Breast Cancer

The purpose of this study is to learn more about how to treat patients with HER-2/neu positive invasive breast cancer (IBC). HER-2/neu is a type of protein that is known to be over-expressed in aggressive breast cancer. The study drug for this trial is DC1 study vaccine which is a HER2-sensitized dendritic cell (DC) study vaccine. This study vaccine is made from the participant's blood cells collected from a procedure called leukapheresis. Dendritic cells are immune cells that can tell the immune system to fight infection. In laboratory testing and from previous studies in participants, these cells may also help the immune system attack tumors such as breast cancer.
