HER2 clinical trials at University of California Health

This is an open-label, first-in-human (FIH), phase 1 dose-escalation and cohort expansion study of BB-1701 in subjects with locally advanced/metastatic HER2 expressing solid tumors. The study consists of 2 parts: dose-escalation (Part 1) and cohort expansion (Part 2). Part 1 consists of dose escalation cohorts for determining the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D). Part 2 consists of expansion cohorts, including but not limited to breast cancer, gastric/gastroesophageal junction cancer, bladder cancer and colon cancer, for exploring 1 or more RP2Ds or schedules for expanding/deepening the information/knowledge about clinical safety, clinical pharmacokinetics and anti-tumor activity.

The purpose of this study is to learn about the safety and effects of giving vepdegestrant along with PF-07220060. Vepdegestrant is studied to see if it can be a possible treatment for advanced metastatic breast cancer. This type of cancer would have spread from where it started (breast) to other parts of the body and would be tough to treat. The study is seeking for participants who have breast cancer that: - is hard to treat (advanced) and may have spread to other organs (metastatic). - is sensitive to hormonal therapy (it is called estrogen receptor positive). - is no longer responding to treatments taken before starting this study. All the participants will receive vepdegestrant and PF-07220060. Both medicines will be taken by mouth. The medicines will be taken at home. The experience of people receiving the study medicines will be studied. This will help see if the study medicines are safe and effective. Participants will continue to take vepdegestrant and PF-07220060 until: - their cancer is no longer responding, or - side effects become too severe. They will have visits at the study clinic about every 4 weeks.

This phase II trial tests how well ARX788 works in treating patients diagnosed with HER2-low, locally advanced unresectable or metastatic breast cancer. ARX788 is an antibody-drug conjugate (ADC) that is given by infusion (diluted and injected slowly into veins). Antibodies are proteins which are naturally produced by the body's immune system to help fight infections. ARX788 consists of antibodies that have been attached to a toxin that has the potential to kill cancer cells. ARX788 sticks to a protein called human epidermal growth factor receptor (HER2), which is found on some breast cancer cells. Giving ARX788 may be safe and effective in treating patients with HER2-low locally advanced unresectable metastatic breast cancer.

Phase III, double-blind, randomised study assessing the efficacy of capivasertib + fulvestrant vs placebo + fulvestrant for the treatment of patients with locally advanced (inoperable) or metastatic HR+/HER2- breast cancer following recurrence or progression on or after AI therapy.

This two-part study will include a dose escalation part to determine the recommended dose for expansion of DS8201a and pembrolizumab and a dose expansion part to evaluate efficacy, safety, and tolerability of the combination.

The purpose of this research study is to determine how well neratinib works in treating breast cancer that has spread to the brain. Neratinib is a recently discovered oral drug that may stop breast cancer cells from growing abnormally by inhibiting (or blocking) members of a family of proteins that include Human Epidermal Growth Factor Receptor 2 (HER2). In this research study, the investigators are looking to see how well neratinib works to decrease the size of or stabilize breast cancer that has spread to the brain. The investigators are also looking at how previous treatments have affected your thinking (or cognition) and how much neratinib reaches the central nervous system.

The primary objective of this study is to demonstrate that the combination of palbociclib with anti-HER2 therapy plus endocrine therapy is superior to anti-HER2-based therapy plus endocrine therapy alone in improving the outcomes of subjects with hormone receptor-positive, HER2+ metastatic breast cancer.

The safety and efficacy of pembrolizumab plus the investigator's choice of chemotherapy will be assessed compared to placebo plus the investigator's choice of chemotherapy in the treatment of chemotherapy-candidate hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) locally recurrent inoperable or metastatic breast cancer. The primary hypotheses are that the combination of pembrolizumab and chemotherapy is superior to placebo and chemotherapy in regards to Progression-Free Survival (PFS) in participants with programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥1.

This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not approved this drug for use patients undergoing adjuvant treatment for HER2+ breast cancer. Trastuzumab emtansine (T-DM1) is a drug that may stop cancer cells from growing. This drug has been used in other research studies and information from those other research studies suggests that this drug may help to prevent the recurrence of breast cancer in this research study. The use of T-DM1 in this research study is experimental, which means it is not approved by any regulatory authority for the adjuvant treatment of HER2-positive breast cancer. However, it FDA-approved for metastatic HER2-positive breast cancer. T-DM1 has caused cancer cells to die in laboratory studies. In preclinical studies, this drug has prevented or slowed the growth of breast cancer. The breast cancer treatments (paclitaxel and Trastuzumab) used in this study are considered part of standard-of-care regimens in early breast cancer. A standard treatment means that this is a treatment that would be accepted by the majority of the medical community as a suitable treatment for your type of breast cancer. In this research study, the investigators are looking to see if the study drug T-DM1 will have less side effects than traditional HER2-positive breast cancer treatment of trastuzumab and paclitaxel. The investigators are also hoping to learn about the long term benefits and disease-free survival of participants who take the study drug T-DM1 in comparison to those participants to take the combination of trastuzumab and paclitaxel.

This phase II trial compares the effect of usual treatment of docetaxel chemotherapy plus trastuzumab, to ado-emtansine (T-DM1) in patients with HER2-postive salivary gland cancer that has come back (recurrent), that has spread from where it first started (primary site) to other places in the body, or cannot be removed by surgery (unresectable). This trial is also testing how well trastuzumab deruxtecan works in treating patients with HER2-low recurrent or metastatic salivary gland cancer. Trastuzumab is a form of targeted therapy because it works by attaching 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 body's immune system. Trastuzumab emtansine contains trastuzumab, linked to a chemotherapy drug called emtansine. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers emtansine to kill them. Trastuzumab deruxtecan is a monoclonal antibody called traztuzumab, linked to a chemotherapy drug called deruxtecan. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors and delivers deruxtecan to kill them. Docetaxel is in a class of medications called taxanes. It stops cancer cells from growing and dividing and may kill them. Trastuzumab emtansine may work better compared to usual treatment of chemotherapy with docetaxel and trastuzumab or trastuzumab deruxtecan in treating patients with recurrent, metastatic or unresectable salivary gland cancer.

This research study is studying a combination of drugs as a possible treatment for breast cancer. The drugs involved in this study are: - Group A: Trastuzumab (Herceptin) + Vinorelbine (Navelbine) - Group B: Trastuzumab + Vinorelbine + Avelumab - Group C: Trastuzumab + Vinorelbine + Avelumab + Utomilumab (PF-05082566)

A phase 2 non-randomized study to assess the safety and efficacy of the combination of tucatinib and trastuzumab with capecitabine for the treatment of leptomeningeal metastases in HER2-neu positive breast cancer.

This single arm, multicenter study provides the pertuzumab and trastuzumab fixed-dose combination formulation for subcutaneous injection (PH FDC SC) administered at home by a home health nursing provider for patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer who have completed concurrent chemotherapy with pertuzumab (Perjeta) and trastuzumab (Herceptin) by intravenous administration (P+H IV) and are currently receiving or will be receiving maintenance therapy with P+H IV, PH FDC SC, or trastuzumab SC in the clinic. The main objective is to enable continuity of care during the COVID-19 pandemic. This study will enroll approximately 200 patients in the United States. Participants with early or metastatic HER2+ breast cancer will be enrolled in this study. Participants with metastatic HER2+ breast cancer will receive treatment every 3 weeks and continue treatment unless early cessation is necessary due to disease recurrence, disease progression, unacceptable toxicity, participant withdrawal of consent, or per physician's recommendation. Participants with early HER2+ breast cancer will receive PH FDC SC to complete 1 year (up to 18 cycles) of dual blockade, including the P+H IV, PH FDC SC, or trastuzumab SC they received prior to enrolling in this study, unless early cessation is necessary due to disease recurrence, disease progression, unacceptable toxicity, participant withdrawal of consent, or per physician's recommendation. A remote cardiac surveillance substudy will be optional for patients enrolled at select sites. The Sponsor may decide to terminate the study when the COVID-19 pandemic is no longer a risk for this patient population.
