Vaccines Treatment Options in California

The study is divided into 2 parts: Part 1 and Part 2. The purpose of Part 1 of this study is to generate sufficient safety, reactogenicity, and immunogenicity data to enable selection of an mRNA-1083 vaccine composition and dose level to evaluate in a subsequent Phase 3 clinical trial in adults. The purpose of Part 2 of this study is to generate safety and immunogenicity data for additional mRNA-1083 compositions and dose levels in young adults ≥18 years and \<50 years of age. Read Less

This study is designed to describe the short-term immunogenicity and safety of 2 doses of Neisseria meningitidis group A, B, C, W, and Y vaccine (MenABCWY) separated by either 12 or 36 months during adolescence, and immunopersistence up to 24 months after completing 2 doses separated by a 12-month interval.

This phase I trial tests the safety and side effects of a PD-L1/IDO peptide vaccine (IO102-IO103) in combination with pembrolizumab in treating patients with non-muscle invasive bladder cancer. IO102-IO103 is a novel IDO and PD-L1 peptide based immune-modulatory therapeutic. It is designed to activate the patient's own immune cells (called T-cells) to fight the tumor and stop the tumor cells escaping from the body's immune system. IO102-IO103 works to directly kill tumor cells and remove the body's immune suppressive cells, which are cells that prevent the immune system from fighting the tumor. 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 IO102-IO103 in combination with pembrolizumab may make tumor cells more visible/recognizable to the immune system. Read Less

The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: * Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. * Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: * Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. * Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: * Group E: Influenza and COVID-19 combination B vaccine. * Group F: COVID-19 vaccine. * Group G: Licenced influenza vaccine. * Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months. This will help understand if the study medicine is safe. Read Less

The purpose of this study is to use an existing, unique clinical cohort: the longitudinal cohort of younger (21-40 years) and elderly (\>65 years) subjects whose yearly influenza vaccine responses have been studied extensively since 2007, to gain molecular and cellular mechanistic insights into the impaired vaccine responses in the elderly.

This is a Phase 2/3, randomized, double-blind study to evaluate the safety and immunogenicity of different booster dose levels of the monovalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recombinant (r) spike (S) protein nanoparticle (SARS-CoV-2 rS) vaccines with Matrix-M™ adjuvant (NVX-CoV2373 \[prototype Wuhan vaccine with Matrix-M adjuvant\] or NVX-CoV2601 \[Omicron XBB.1.5 subvariant vaccine with Matrix-M adjuvant\]).

This is a prospective randomized clinical trial evaluating how behaviorally-informed outreach text messages affect the take-up of bivalent COVID-19 booster. The investigators will test the impact of sending text reminders as well as the importance of elevating vaccination intentions, facilitating action, and their combination. Read Less

The purpose of this study is to determine whether ETBX-021 is safe and effective in the treatment of unresectable locally advanced or metastatic HER2-low-expressing breast cancer. Read Less

An antibody is a substance your body makes to fight off infection. This study will explore the safety and antibody response of a vaccine to prevent severe diarrhea caused by a germ called Clostridoides difficile (C. diff). Three new formulations of the C. diff vaccine will be used in this study, in addition to a C. diff vaccine formulation that has been studied in previous clinical trials. The purpose of this study is to understand if giving the new C. diff vaccine formulations helps people make as many antibodies as giving the previously studied C. diff vaccine formulation. The study is divided into 2 phases. Phase 1 will evaluate 3 new formulations of the C. diff vaccine and 2 dosing schedules spread out over 2 months or 6 months. The Phase 1 portion of the study is seeking participants: * who are healthy adults of 65 to 84 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. All participants in Phase 1 will receive study injections with active vaccine or placebo at each vaccination visit, depending on the vaccine group to which they are assigned. A placebo does not contain any active ingredients. Participants in Phase 1 will attend at least 9 study visits and will take part in the study for approximately 18 months. Based on the results of Phase 1, 1 or 2 of the new C. diff vaccine formulations will be chosen for further study in Phase 2. Phase 2 will evaluate the safety and effects of the new C. diff vaccine formulation(s) chosen in Phase 1. The Phase 2 portion of the study is seeking participants: * who are healthy adults ≥65 years of age * who have not had a C. diff infection before * who have not received a C. diff vaccine or C. diff monoclonal antibody therapy before. Phase 2 participants will receive active C. diff vaccine or placebo at each vaccination visit. Participants in Phase 2 will attend at least 6 and up to 12 study visits and will take part in the study for up to 4 years. Read Less

This phase II trial will examine whether genetically reprogramming a patient's disease fighting white blood cells may build an immune response to kill cancer cells that express the NY-ESO-1 protein. In this study, this genetic therapy will be given during a stem cell transplant along with a vaccine therapy. The vaccine will be made using the NY-ESO-1 protein and may help to stimulate the engineered immune response to tumor cells. Read Less
