Testing the Safety of the Combination of Anti-Cancer Drugs CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd) for Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Solid Tumors and Breast Cancer

This phase I trial tests the safety, side effects, and best dose of pidnarulex in combination with trastuzumab deruxtecan in treating patients with breast cancer and other solid tumors that express varying levels of a protein called HER2 and that has spread from where it first started (primary site) to other places in the body (metastatic), that cannot be removed by surgery (unresectable), or that has spread to nearby tissue or lymph nodes (locally advanced). Pidnarulex is an enzyme inhibitor that causes cell death and prevents tumor cell growth. Trastuzumab deruxtecan is in a class of medications called antibody-drug conjugates. It is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Giving pidnarulex in combination with trastuzumab deruxtecan may be safe, tolerable and/or effective in treating patients with metastatic, unresectable, or locally advanced HER2-expressing breast cancer or other solid tumors.

A Vaccine (STEMVAC) With Standard Endocrine-Based Therapy or Chemotherapy for the Treatment of Metastatic Hormone Receptor Positive, HER2 Negative Breast Cancer

This phase II trial studies how well a vaccine, STEMVAC, works in combination with standard endocrine-based therapy (ET) with a CDK4/6 targeted drug therapy, or with the chemotherapy drug capecitabine, in treating patients with hormone receptor (HR)-positive, HER2-negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). STEMVAC is designed to target proteins that cancer cells use when they become more aggressive and start to spread, and it is believed to work by boosting the immune system to recognize and destroy the invader tumor cells that are causing the disease. Standard ET is treatment that adds, blocks, or removes hormones in order to slow or stop the growth of cancer. Standard CDK4/6 inhibitors, including abemaciclib, may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Giving STEMVAC in combination with standard ET or chemotherapy may be an effective treatment for metastatic HR positive, HER2 negative breast cancer.

Personalized Neo-Antigen Peptide Vaccine for the Treatment of Stage IIIC-IV Melanoma, Hormone Receptor Positive HER2 Negative Metastatic Refractory Breast Cancer or Stage III-IV Non-Small Cell Lung Cancer

This phase I trial studies the safety of personalized neo-antigen peptide vaccine in treating patients with stage IIIC-IV melanoma, hormone receptor positive HER2 negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or does not respond to treatment (refractory) or stage III-IV non-small cell lung cancer. Personalized neo-antigen peptide vaccine is a product that combines multiple patient specific neo-antigens. Given personalized neo-antigen peptide vaccine together with Th1 polarizing adjuvant poly ICLC may induce a polyclonal, poly-epitope, cytolytic T cell immunity against the patient's tumor.

Functional Imaging in Prediction of Response to Abemaciclib for Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer

This phase II trial tests the accuracy of functional imaging (FFNP)-positron emission tomography (PET)/computed tomography (CT) to predict response to abemaciclib plus endocrine therapy. Abemaciclib is a drug used to treat certain types of hormone receptor positive (HR+), HER2 negative breast cancer. Abemaciclib blocks certain proteins, which may help keep tumor cells from growing. Endocrine therapy adds, blocks, or removes hormones that can cause cancer to grow. FFNP PET imaging is a form of x-ray that uses FFNP as an imaging agent that may provide more precise information about the location of tumors that "light up" with FFNP than a PET scan alone can provide.

Testing the Addition of Copanlisib to Usual Treatment (Fulvestrant and Abemaciclib) in Metastatic Breast Cancer

This phase I trial studies the effects (good and bad) of adding copanlisib to the usual therapy of fulvestrant and abemaciclib in treating patients with hormone receptor positive and HER2 negative breast cancer that has spread from where it first started (breast) to other places in the body (metastatic). Some breast cancer cells have receptors for the hormones estrogen or progesterone. These cells are hormone receptor positive and they need estrogen or progesterone to grow. This can affect how the cancer is treated. Hormone therapy using fulvestrant may fight breast cancer by blocking the use of estrogen by the tumor cells. Abemaciclib and copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Adding copanlisib to the usual therapy of fulvestrant and abemaciclib may work better than giving fulvestrant and abemaciclib alone in treating patients with breast cancer.
