Recruiting
This study is a Phase 3, randomized, modified double-blind study which aims to measure whether PCV21 vaccine (investigational pneumococcal conjugate vaccine) is safe and can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) compared with 20-valent pneumococcal vaccine (Prevnar 20, licensed pneumococcal conjugate vaccine) when they are administered with routine pediatric vaccines in infants aged from approximately 2 months (42 to 89 days). The study duration per... Read More

Cancer Preventive Vaccine Nous-209 for Lynch Syndrome Patients
Active Not Recruiting
This phase Ib/II trial evaluates the safety and effect of the Nous-209 vaccine in Lynch syndrome patients. Lynch syndrome is an inherited disorder in which affected individuals have a higher-than-normal chance of developing colorectal cancer and certain other types of cancer, often before the age of 50. In Lynch syndrome, errors in the genetic information inside cells are not properly corrected. When that happens, the cells produce new proteins called neoantigens. Neoantigens are recognized by t...

DNA Vaccine Therapy in Treating Patients With Chronic Hepatitis C Virus Infection
Active Not Recruiting
This phase I trial studies the side effects and best dose of deoxyribonucleic acid (DNA) vaccine therapy in treating patients with hepatitis C virus (HCV) infection that persists or progresses over a long period of time. Vaccines made from DNA may help the body build an effective immune response to kill cancer cells that express HCV infection.

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

COVID19 SARS Vaccinations: Systemic Allergic Reactions to SARS-CoV-2 Vaccinations
Completed
Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: * To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a... Read More

Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to oth... Read More
