Vanderbilt's Neil Osheroff, PhD, is part of an international research collaboration resulting in what is on track to be the first new antibiotic treatment for uncomplicated urinary tract infections in more than 20 years.
New research shows the nutritive needs of B cells are more flexible than previously thought, which could enable researchers to steer antibody production in the lymph nodes and spleen to better combat autoimmunity. Patients with high-risk diseases of the immune system, particularly systemic lupus erythematosus, could stand to benefit from the research findings. The study led by Mark Boothby, MD, and published in the Journal of Immunology, provides details regarding how murine B cells use different sugars as they mature into antibody-producing cells
An international collaboration led by biochemist David Cortez reached revelatory conclusions in exploration of how cells tolerate DNA damage and genome instability. Est. reading time: 2 mins.
This phase II ADC MATCH screening and multi-sub-study treatment trial is evaluating whether biomarker-directed treatment with one of three antibody-drug conjugates (ADCs) (sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan) works in treating patients with solid tumor cancers that have high expression of the Trop-2, nectin-4, or HER2 proteins and that may have spread from where they first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced) or to other places in the body (metastatic). Precision medicine is a form of medicine that uses information about a person's genes, proteins, and environment to prevent, diagnose, or treat disease in a way that is tailored to the patient. ADCs such as sacituzumab govitecan, enfortumab vedotin, and trastuzumab deruxtecan are monoclonal antibodies attached to biologically active drugs and are a form of targeted therapy. Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a drug called govitecan. Sacituzumab attaches to a protein called Trop-2 on the surface of tumor cells and delivers govitecan to kill them. Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. It works by helping the immune system to slow or stop the growth of tumor cells. Enfortumab attaches to a protein called nectin-4 on tumor cells in a targeted way and delivers vedotin to kill them. Trastuzumab deruxtecan 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. Personalized treatment with sacituzumab govitecan, enfortumab vedotin, or trastuzumab deruxtecan may be an effective treatment option for patients with advanced or metastatic solid tumors that screen positive for high expression of Trop-2, nectin-4, or HER2, respectively.
This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy \[cisplatin and carboplatin\] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Carboplatin is also in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer 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 pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.
This phase III trial compares the effect of adding cemiplimab to standard therapy (surgery with or without radiation) versus standard therapy alone in treating patients with stage III/IV squamous cell skin cancer that is able to be removed by surgery (resectable) and that may have come back after a period of improvement (recurrent). The usual treatment for patients with resectable squamous cell skin cancer is the removal of the cancerous tissue (surgery) with or without radiation, which uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cemiplimab has been approved for the treatment of skin cancer that has spread or that cannot be removed by surgery, but it has not been approved for the treatment of skin cancer than can be removed by surgery. Adding cemiplimab to the usual treatment of surgery with or without radiation may be more effective in treating patients with stage III/IV resectable squamous cell skin cancer than the usual treatment alone.
The purpose of this study is to determine if panitumumab-IRDye800 is effective in identifying cancer, compared to surrounding normal tissue, and the further characterize the safety profile of this drug.

The goal of this clinical trial is to evaluate the safety of TOS-358 in adults with select solid tumors who meet study enrollment criteria. The main questions it aims to answer are:
1. what is the maximum tolerated dose and recommended dose for phase 2?
2. how safe and tolerable is TOS-358 at different dose levels when taken orally once or twice per day?

This phase II trial tests how well nivolumab and ipilimumab immunotherapy with or without cabozantinib works in treating patients with nasopharyngeal cancer that has come back (after a period of improvement) (recurrent), has spread from where it first started (primary site) to other places in the body (metastatic), or for which no treatment is currently available (incurable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving immunotherapy with nivolumab and ipilimumab and targeted therapy with cabozantinib may help shrink and stabilize nasopharyngeal cancer.
