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

Epstein-Barr Virus (EBV) gH/gL/gp42-Ferritin Nanoparticle Vaccine With or Without gp350-Ferritin in Healthy Adults With or Without EBV Infection
Recruiting
Background: Epstein-Barr virus (EBV) is the primary cause of infectious mononucleosis, commonly known as mono. EBV infects more than 90% of the world s population. Mono can be serious, and it can lead to severe illnesses like cancer and autoimmune diseases. Researchers want to test vaccines that may help prevent EBV and associated diseases. Objective: To test two EBV vaccines: EBV gH/gL/gp42-ferritin and EBV gp350-ferritin. Eligibility: Healthy EBV-negative or EBV-positive people aged 18 to... Read More

COVID-19 Protection After Transplant Pilot Study
Completed
Antibodies are an important part of the body's defense against infection. Individuals who have no antibodies or very low antibody levels are considered less well protected from Coronavirus Disease 2019 (COVID-19) than those who have higher antibody levels. What level of antibodies is necessary for protection is currently unknown. Inadequate antibody response to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination has been described among kidney transplant recipients. The aim... Read More
