Testing the Addition of an Individualized Vaccine to Durvalumab and Tremelimumab and Chemotherapy in Patients With Metastatic Triple Negative Breast Cancer

This phase II trial studies how well nab-paclitaxel, durvalumab, and tremelimumab with or without personalized synthetic long peptide vaccine (neoantigen vaccine) works in treating patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as nab-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. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. It is not yet known whether giving nab-paclitaxel, durvalumab, and tremelimumab with or without neoantigen vaccine will work better in treating patients with triple negative breast cancer.

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.

Targeted Therapy Directed by Genetic Testing in Treating Patients With Locally Advanced or Advanced Solid Tumors, The ComboMATCH Screening Trial

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.

Testing Proton Craniospinal Radiation Therapy Versus the Usual Radiation Therapy for Leptomeningeal Metastasis, RADIATE-LM Trial

This phase III trial compares proton craniospinal irradiation (pCSI) to involved-field radiation therapy (IFRT) for the treatment of breast or non-small cell lung cancer that has spread from where it first started to the cerebrospinal fluid filled space that surrounds the brain and spinal cord (leptomeningeal metastasis). Patients with leptomeningeal metastasis (LM) may develop multiple areas of nervous system (neurologic) impairment that can be life-threatening. Radiation therapy (RT) effectively relieves local symptoms due to LM. RT uses high energy radiography (x-rays), particles, or radioactive seeds to kill cancer cells and shrink tumors. IFRT is commonly used to treat symptoms of LM. IFRT is radiation treatment that uses x-rays to treat specific areas of LM and to relieve and/or prevent symptoms. pCSI uses protons that can be directed with more accuracy than x-rays which allows treatment of the entire central nervous system space containing the cerebrospinal fluid (CSF), brain, and spinal cord. The pCSI treatment could delay the worsening of LM. Giving pCSI may be better than IFRT in treating LM in patients with breast or non-small cell lung cancer.

Testing Longer Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With Cancer That Has Spread to the Brain

This phase III trial compares the effectiveness of fractionated stereotactic radiosurgery (FSRS) to usual care stereotactic radiosurgery (SRS) in treating patients with cancer that has spread from where it first started to the brain. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. FSRS delivers a high dose of radiation to the tumor over 3 treatments. SRS is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. FSRS may be more effective compared to SRS in treating patients with cancer that has spread to the brain.

Leuprolide and Goserelin for Ovarian Function Suppression in Pre- or Peri-menopausal Women With Breast Cancer, OFS Trial

This phase II trial compares leuprolide to goserelin for reducing estrogen production by the ovaries in pre- or peri-menopausal women with breast cancer. Estrogen can cause the growth of breast cancer cells. Both leuprolide and goserelin lower the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. This study compares lower dose leuprolide, higher dose leuprolide, and goserelin for their ability to suppress the function of the ovaries to produce estrogen. Both doses of leuprolide may be as safe, tolerable and/or effective as goserelin in suppressing ovarian function in pre- or peri-menopausal women with breast cancer.

Personalized Neoantigen Peptide-Based Vaccine in Combination With Pembrolizumab for Treatment of Advanced Solid Tumors

This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

Measuring the Effects of Talazoparib in Patients With Advanced Cancer and DNA Repair Variations

This phase II trial studies if talazoparib works in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. All patients who take part on this study must have a gene aberration that changes how their tumors are able to repair DNA. This trial may help scientists learn whether some patients might benefit from taking different PARP inhibitors "one after the other" and learn how talazoparib works in treating patients with advanced cancer who have aberration in DNA repair genes.

Mobile Health for Adherence in Breast Cancer Patients

This clinical trial compares the use of the connected customized treatment platform (CONCURxP), consisting of using a medication monitoring device called WiseBag along with text message reminders for missed or extra medication events, to enhanced usual care (EUC), where patients only use the WiseBag, to monitor medication adherence in patients with metastatic breast cancer who are taking a CKD4/6 inhibitor. To ensure CDK4/6 inhibitors achieve their full clinical benefit, patients need to take them as prescribed, following a complex treatment schedule. Forgetfulness was the most common reason reported for medication non adherence. Using the WiseBag along with CONCURxP or enhanced usual care may improve medication adherence in patients with metastatic breast cancer who are taking a CKD4/6 inhibitor.

Testing the Safety and Efficacy of the Combination of Two Anti-cancer Drugs, ZEN003694 and Abemaciclib, for Adult and Pediatric Patients (12-17 Years) With Metastatic or Unresectable NUT Carcinoma, Breast Cancer and Other Solid Tumors

This phase I trial tests the safety, side effects, and best dose of ZEN003694 when given together with abemaciclib in treating patients with NUT carcinoma, breast cancer or other solid tumors that have spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable). ZEN003694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that overproduce BET protein. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ZEN003694 and abemaciclib may help shrink or stabilize cancer in patients with NUT carcinoma, breast cancer or other solid tumors.

A Vaccine (MV-s-NAP) for the Treatment of Patients With Invasive Metastatic Breast Cancer

This phase I trial investigates the side effects and best dose of using a modified measles virus, MV-s-NAP, in treating patients with invasive breast cancer that has spread to other places in the body (metastatic). Both the unmodified vaccination measles virus (MV-Edm) and this modified virus (MV-s-NAP) have been shown to multiply in and destroy breast cancer cells in the test tube and in research mice. MV-s-NAP has been altered by having an extra gene (piece of deoxyribonucleic acid \[DNA\]) so that virus can make a protein called helicobacter pylori neutrophil activating protein (NAP) which is normally expressed in inflammatory reactions. Monitoring blood, urine, tissue, and throat swab samples, and using imaging tests may help to determine whether MV-s-NAP has any impact on the amount of disease present in metastatic breast cancer patients.

Hippocampal Avoidance in Craniospinal Irradiation for the Treatment of Leptomeningeal Metastases From Breast Cancer or Non-small Cell Lung Cancer

This phase II clinical trial studies how well craniospinal irradiation (CSI) with hippocampal avoidance, using proton therapy or volumetric modulated arc therapy (VMAT), works in treating patients with breast cancer or non-small cell lung cancer (NSCLC) that has spread from the original (primary) tumor to the cerebrospinal fluid (CSF) and meninges (thin layers of tissue that cover and protect the brain and spinal cord) (leptomeningeal metastases). Radiation therapy is an effective treatment in relieving localized symptoms caused by leptomeningeal metastases. However, the type of radiation therapy typically used does not prevent the spread of leptomeningeal disease. CSI (radiation therapy directed at the brain and spinal cord to kill tumor cells) may be able to target all of the areas of possible leptomeningeal tumor spread. CSI may however result in significant neurological side effects due to radiation damage to a part of the brain called the hippocampus. Hippocampal avoidance (HA) reduces the amount of radiation to the hippocampus. Proton or VMAT CSI with HA may be an effective treatment while reducing neurological side effects for patients with leptomeningeal metastases from breast cancer and NSCLC.

Propranolol and Pembrolizumab for Tumor Re-sensitization and Treatment of Patients With Checkpoint Inhibitor Refractory Metastatic or Unresectable Triple Negative Breast Cancer

This phase II trial tests how well propranolol and pembrolizumab work to cause tumor re-sensitization and therefore treatment in patients with triple negative breast cancer that has not responded to previous checkpoint inhibitor therapy (refractory), cannot be removed by surgery (unresectable) or has spread from where it first started (primary site) to other places in the body (metastatic). Propranolol is a drug that is classified as a beta-blocker. Beta-blockers affect the heart and circulation. Beta-blockers, like propranolol, may help to counteract effects of certain stress hormones produced by the body during cancer treatment and may increase the effectiveness of the pembrolizumab. Pembrolizumab is a drug that is classified as an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Propranolol may be able to re-sensitize the cells of the immune system to respond to the checkpoint inhibitor pembrolizumab in patients with checkpoint inhibitor refractory metastatic or unresectable triple negative breast cancer.

Adding Surgery and Radiation to the Usual Treatment for HER2-Positive Breast Cancer That Had Already Spread at Diagnosis

This phase III trial evaluates the effect of adding locoregional therapy (surgery and radiation) and metastasis-directed stereotactic body radiation therapy (SBRT) to standard systemic therapy following standard HER2-targeted systemic therapy, compared to standard systemic therapy alone, in treating patients with HER2-positive stage IV breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or to a limited number of sites (oligometastatic). The usual approach for patients with (oligo)metastatic HER2-positive breast cancer is systemic drug treatment, which means medicines that travel through the whole body to treat both the breast and any areas where the cancer has spread. There are a number of approved HER2-targeted systemic therapy regimens available to patients. These typically include immunotherapy and/or chemotherapy. Immunotherapy drugs may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs 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. Unlike systemic therapy, locoregional therapies like surgery and radiation are focused treatments at the site of disease, delivered with the intent of sparing healthy tissues. Breast surgeries such as breast conserving therapy or total mastectomy are procedures in which the cancerous breast tissue (and healthy breast tissue in the case of total mastectomy) are surgically removed from the body. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Adding locoregional therapy, as well as metastasis-directed SBRT, to standard systemic therapy may help patients with (oligo)metastatic, HER2-positive stage IV breast cancer live longer overall or before their cancer progresses, and may help more patients achieve no evidence of disease, when compared to standard systemic therapy alone.

Cemiplimab and Transarterial Radioembolization With Y-90 SIR-S Spheres for the Treatment of Liver Directed Metastatic Breast Cancer

This phase II trial tests how well cemiplimab and transarterial radioembolization (TARE) with yttrium-90 (Y90) SIR-Spheres, registered trademark, works in treating breast cancer that has spread from where it first started (primary site) to the liver (metastatic). Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. TARE is a treatment that uses radioactive microspheres, such as Y90 SIR-S Spheres, to both cause hepatic artery embolization and to deliver regional radiotherapy. Y90 SIR-S Spheres is an injectable form of the radioisotope yttrium Y 90 encapsulated in resin microspheres. When injected into the artery supplying the tumor, yttrium Y 90 resin microspheres block the tumor blood vessels and deliver the yttrium Y 90 directly to the tumor site, which may kill or slow tumor growth. Giving cemiplimab and Y90 SIR-Spheres by TARE to the tumor in the liver may kill more tumor cells in patients with metastatic breast cancer.

Minoxidil With or Without Low-Level Red-Light Therapy for Improving Chemotherapy-Induced Alopecia in Breast Cancer Patients

This phase II trial compares the safety and effectiveness of topical minoxidil alone to topical minoxidil in combination with low-level red-light therapy for improving chemotherapy-induced hair loss or thinning (alopecia). Minoxidil has been approved by the Food and Drug Administration as a treatment for hair loss. It increases blood flow in the skin and may have a direct stimulatory effect on hair follicle cells, forcing them from their resting phase into their active growth phase. Low-level light therapy is regarded as a safe and medically accepted treatment for a variety of skin conditions, including acne, scars, and psoriasis. Red light wavelengths are readily absorbed into the skin and do not contain harmful ultraviolet light. When absorbed into the skin, these wavelengths stimulate fibroblasts, which are connective tissue cells that make and secrete collagen proteins. Low-level red-light therapy may improve hair loss by stimulating hair follicles. Combining minoxidil with low-level red-light therapy may be safe and more effective at improving chemotherapy-induced alopecia than minoxidil alone.
