HER2 clinical trials at UCSF

Some human epidermal growth factor receptor 2 (HER-2) breast cancer patients do not respond or become resistant to current treatment. DS-8201a is a new experimental product that is a combination of an antibody and a drug. It has not yet been approved for use. DS-8201a may slow down tumor growth. This might improve outcomes for these patients.

The purpose of this clinical trial is to learn about the safety and effects of study medicine (PF-06873600) when taken alone or with hormone therapy by people with cancer. People may be able to participate in this study if they have the following types of cancer: Hormone Receptor positive (HR+) breast cancer; Human Epidermal Growth Factor Receptor 2 (HER2)-negative breast cancer that is advanced or metastatic (spread to other parts of the body); triple negative breast cancer; epithelial ovarian cancer; fallopian tube cancer; or primary peritoneal cancer. All participants in this study will receive the study medicine by mouth, 1 to 2 times a day at home. The dose of the study medicine may be changed during the study. Some participants will also receive hormone therapy. The hormone therapy will be either letrozole by mouth once a day at home, or fulvestrant as a shot into the muscle. Fulvestrant will be given every two weeks at the study clinic for the first month, and then once a month after that. Participants will take part in this study for at least 7 to 8 months, depending on how they respond to the therapy. During this time participants will visit the study clinic once a week.

This trial studies how well the drug tucatinib works when given with trastuzumab deruxtecan (T-DXd). It will also look at what side effects happen when these drugs are given together. A side effect is anything a drug does besides treating cancer. Participants in this trial have HER2-positive (HER2+) breast cancer that has either spread to other parts of the body (metastatic) or cannot be removed completely with surgery (unresectable). All participants will get both tucatinib and T-DXd.

A phase III multi-center, randomized, open-label trial to evaluate efficacy and safety of ribociclib with endocrine therapy as adjuvant treatment in patients with HR+/HER2- Early Breast Cancer (EBC)

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 study is designed to compare the anti-tumor activity as well as the safety and efficacy of DS-8201a versus T-DM1 in HER2-positive, unresectable and/or metastatic breast cancer subjects previously treated with trastuzumab and taxane.

To demonstrate the efficacy of enobosarmin the treatment of androgen receptor positive (AR+) and estrogen receptor positive (ER+) metastatic breast cancer (MBC) as measured by radiographic progression free survival (rPFS).

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.

This randomized phase III trial studies paclitaxel and trastuzumab with or without lapatinib to see how well they work in treating patients with stage II or stage III breast cancer that can be removed by surgery. 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. Monoclonal antibodies, such as 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. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving paclitaxel with trastuzumab and/or lapatinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known which regimen is more effective in treating patients with breast cancer.

This is a Phase 2, open-label, multi-center study to evaluate the efficacy and the safety/tolerability of poziotinib in seven patient cohorts for up to 603 previously treated and treatment-naïve NSCLC patients. Cohorts 3 and 4 were added with Amendment 1 and three additional cohorts were added with Amendment 2 (Cohorts 5, 6 and 7).

This Phase 3 clinical study compares the efficacy and safety of elacestrant to the standard of care (SoC) options of fulvestrant or an aromatase inhibitor (AI) in women and men with breast cancer whose disease has advanced on at least one endocrine therapy including a CDK4/6 inhibitor in combination with fulvestrant or an aromatase inhibitor (AI) .

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.

Study assessing the efficacy and safety of alpelisib plus fulvestrant or letrozole, based on prior endocrine therapy, in patients with hormone receptor (HR) positive, HER2-negative advanced breast cancer (aBC), harboring PIK3CA mutations, who have progressed on or after prior treatments.

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 Ib trials studies the side effects and how well talimogene laherparepvec works when given together with chemotherapy or endocrine therapy in treating patients with breast cancer that does not express the human epidermal growth factor receptor 2 (HER2) protein and has spread to other places in the body (metastatic), cannot be removed by surgery (unresectable), or has come back (recurrent). Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may attack specific tumor cells and stop them from growing or kill them. Chemotherapy drugs, such as nab-paclitaxel, gemcitabine, and carboplatin, 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 as endocrine therapy, such as letrozole, anastrozole, exemestane, tamoxifen or fulvestrant, may lessen the amount of estrogen made by the body or may may stop the growth of tumor cells by blocking estrogen from connecting to the cancer cells. Giving talimogene laherparepvec with chemotherapy or endocrine therapy may work better in treating patients with HER2-negative breast cancer.

This randomized phase II trial studies how well olaparib with or without atezolizumab work in treating patients with non-HER2-positive breast cancer that has spread to nearby tissue or lymph nodes (locally advanced), that cannot be removed by surgery (unresectable), or that has spread from where it first started (primary site) to other places in the body (metastatic). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. It is not known whether giving olaparib with or without atezolizumab will work better in patients with non-HER2-positive breast 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)

This study will compare DS-8201a to physician choice standard treatment. Participants must have HER2-low breast cancer that has been treated before. Participants' cancer: - Cannot be removed by an operation - Has spread to other parts of the body

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.
