Phase 2, Randomized, Active-Controlled, Observer-Blinded, Multicenter Trial of the Immunogenicity, Safety, and Tolerability of rF1V Vaccine with CpG 1018® Adjuvant Compared with rF1V Vaccine in Adults 18 to 55 Years of Age Read Less

This study was designed to evaluate the safety and tolerability of a single dose of V114 when administered concomitantly and non-concomitantly (i.e., 30 days after) with influenza vaccine. It also evaluated whether V114 can be administered concomitantly with influenza vaccine without impairing the antibody response to the 15 serotypes contained in V114 and to the 4 influenza viruses contained in the seasonal inactivated quadrivalent influenza vaccine (QIV). The primary hypotheses state that immune responses to V114 and to QIV are non-inferior when administered concomitantly as compared with non-concomitant administration as measured by serotype-specific opsonophagocytic activity (OPA) and hemagglutination inhibition (HAI) geometric mean titers (GMTs) at 30 days postvaccination. This study will also contribute to the overall safety database and immunogenicity data for V114 to support initial licensure in adults. Read Less

The primary objectives of the study were: * To assess the safety profile of each dose of the study product after each and any administration in all infants and toddlers regardless of baseline serostatus. * To characterize the Respiratory Syncytial Virus (RSV) A serum neutralizing antibody responses to the study product in each vaccine group after vaccination in RSV-naïve participants. The secondary objectives of the study were: * To quantify the amount of vaccine virus shed by each participant by baseline serostatus. * To determine the proportion of vaccinated infants and toddlers in each vaccine group infected with the vaccine virus at D56 (56 days after vaccination 1) for Cohorts 1, 2, 3 and 4, and at Day 84 (28 days after vaccination 2) for Cohorts 2 and 4 by baseline serostatus. * To characterize the RSV A serum neutralizing antibody responses to the study product in each vaccine group after vaccination in RSV-experienced participants. * To characterize serum RSV anti-F immunoglobulin G (IgG) antibody responses to the study product in each vaccine group after vaccination by baseline serostatus. * To characterize serum RSV antibody responses (RSV A-neutralizing and anti-RSV F IgG) to the study product in each vaccine group after the RSV surveillance season or at least 5 months after the last vaccine administration by baseline serostatus.

This phase 1/2 trial tests the safety and effectiveness of a cancer vaccine called Labvax 3(22)-23 and GM-CSF alone or in combination with pembrolizumab in treating adenocarcinoma that has spread to other places in the body (advanced stage). Labvax 3(22)-23 is designed to target a specific antigen (labyrinthin), which is a protein found on the surface of adenocarcinoma tumor cells. Labyrinthin is a protein that is not expressed on normal cells in the skin, lungs, salivary glands, pancreas, nor other tissues. In adenocarcinoma, the tumor cells produce too much labyrinthin causing them to express this protein on the surface of the tumor cells. One way to control the growth of these tumor cells is to teach the immune system to generate an immune response against the labyrinthin protein by vaccination against labyrinthin. GM-CSF, or sargramostim, is a protein that acts as a white blood cell growth factor. It has also been shown to stimulate immune system. Thus, administration of GM-CSF may help to boost the immune system response when given together with the vaccine. This study may improve the general knowledge about Labvax 3(22)-23 and how the body may generate an immune response to kill adenocarcinoma tumor cells. In the second phase of the study, participants will also receive pembrolizumab, which may improve anti-cancer activity when given with Labvax 3(22)-23 and GM-CSF. Read Less

The study is designed as a Phase II, multicenter trial of vaccination with Dendritic cell/myeloma fusions with granulocyte macrophage colony-stimulating factor (GM-CSF) adjuvant plus lenalidomide maintenance therapy versus maintenance therapy alone or with GM-CSF following autologous transplant as part of upfront treatment of multiple myeloma (MM). It is hypothesized that the dendritic cell myeloma vaccine will result in improved response in patients with multiple myeloma after autologous Hematopoietic Cell Transplant (HCT). Read Less

This is a randomized, multi-site, adaptive, open-label clinical trial comparing the immune response to different additional doses of COVID-19 vaccine in participants with autoimmune disease requiring IS medications. All study participants will have negative serologic or suboptimal responses (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result ≤200 U/mL) or a low immune response (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result \>200 U/ml and ≤2500 U/mL) to their previous doses of COVID-19 vaccine. The study will focus on 5 autoimmune diseases in adults: * Systemic Lupus Erythematosus (SLE) * Rheumatoid Arthritis (RA) * Multiple Sclerosis (MS) * Systemic Sclerosis (SSc), and * Pemphigus. This study will focus on 4 autoimmune diseases in pediatric participants: * Systemic Lupus Erythematosus (SLE) * Juvenile Idiopathic Arthritis (JIA) * Pediatric-Onset Multiple Sclerosis (POMS) * Juvenile Dermatomyositis (JDM) Read Less

In this Phase 4, open-label trial, participants of the ACTIV-3/TICO clinical trial at selected sites who received certain pre-specified blinded investigational agents or placebo as part of that trial, and who have since achieved sustained recovery, and who are still \[TICO assignment\] blinded and who are still within 28 to 90 days after initial TICO randomization, will be randomized in this 2x2 factorial design to one of four groups: (i) immediate versus 12 week deferral of first dose administration and also (ii) one dose only, versus two doses to be given 4 weeks apart of the Moderna mRNA-1273 or the Pfizer BNT162b2 vaccine (mRNA vaccines). Choice of Moderna or Pfizer vaccine is determined based on availability at the site. The choice is individual, although participants vaccinated twice should receive the same type of vaccine for both injections. The primary objectives of this 2x2 factorial design are (i) to estimate the difference in neutralizing antibody (NAb) response to the mRNA vaccine from baseline to Week 48 among participants vaccinated early versus deferred, and (ii) to estimate the difference in NAb response to this vaccine among participants vaccinated once versus twice. The primary analyses will be carried out in participants randomized to placebo in TICO. Analyses will also be carried out for those who receive the investigational agent(s) studied in TICO. A key secondary objective is to ascertain the effect, if any, of SARS-CoV-2 monoclonal antibodies, and other interventions that have been studied in hospitalized COVID-19 subjects, on natural and vaccine-induced immunity. Participants will remain blinded to the interventions received in the ACTIV-3/TICO study, however allocation to the timing of vaccination and to one or two vaccinations in this (VATICO) study is not blinded.

The purpose of this study was to evaluate the effectiveness of 2 doses or 3 doses of GSK's licenced meningococcal group B Bexsero (rMenB+OMV NZ) vaccine and of 2 doses of GSK's investigational combined meningococcal (MenABCWY) vaccine (GSK3536819A) in healthy adolescents and young adults. The immunogenicity and safety were evaluated in the study. Read Less
