This phase II trial studies how well FASN inhibitor TVB-2640 and trastuzumab plus either paclitaxel or endocrine therapy with an aromatase inhibitor work in treating patients with HER2 positive breast cancer that has spread to other places in the body. FASN inhibitor TVB-2640 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and trastuzumab, 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. Endcocrine therapy helps reduce the hormones that feed tumor cells. Giving FASN inhibitor TVB-2640 and trastuzumab with either paclitaxel or endocrine therapy may work better in treating patients with HER2 positive breast cancer.

The purpose of this study is to evaluate the addition of 2 years of palbociclib to standard adjuvant endocrine therapy for patients with HR+ / HER2- early breast cancer to determine whether the addition of palbociclib will improve outcomes over endocrine therapy alone.

This is a two arm Phase III trial in first and second-line HER2 negative patients with locally recurrent or metastatic breast cancer. The primary endpoint is overall survival (OS), and the objective is to test for the superiority of eribulin mesylate over standard weekly paclitaxel. Patients will be randomized between the experimental and control arm with equal allocation (1:1) within strata defined by prior adjuvant taxanes, hormone receptor status, and line of therapy. Subjects will continue protocol directed therapy until documentation of disease progression, development of unacceptable toxicity, or withdrawal of consent. Those who discontinue study treatment without radiological progression will be followed with repeat imaging studies every 12 weeks. All subjects will be followed until death, withdrawal of consent, or study termination.

The purpose of this study is to evaluate how well multi-epitope folate receptor alpha peptide vaccine, sargramostim, and cyclophosphamide work in treating patients with triple negative breast cancer. Vaccines made from a person's white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, 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. Giving multi-epitope folate receptor alpha peptide vaccine, sargramostim, and cyclophosphamide may work better in treating patients with triple negative breast cancer.
