Active clinical trials for "Meningitis, Meningococcal"

It is a Phase 3 extension of study V72P12E1 (NCT00944034). The main aim of the second extension study is to explore the bactericidal antibody persistence in 4-year-old children after a fourth dose boost of rMenB+OMV NZ or after a two-dose catch-up schedule of rMenB+OMV NZ administered to toddlers as part of their respective vaccination courses in study V72P12E1. In addition, this study will characterize the antibody response to a fifth dose boost in all children who received a three-dose primary series of rMenB+OMV NZ at 2, 3, 4 months of age (in parent study V72P12, NCT00721396), and only in a subset of children who received a three-dose primary series of rMenB+OMV NZ at 2, 4, 6 months of age (in parent study V72P12). Antibody response will also be characterized to a third dose boost of rMenB+OMV NZ administered at approximately 4 years of age in all children who received a two catch-up doses of rMenB+OMV NZ as toddlers in study V72P12E1. Finally, the safety and immunogenicity of two catch-up doses of rMenB+OMV NZ administered 2 months apart to healthy naïve children at 4 years of age will be assessed.

This study will assess the safety, tolerability and immunogenicity of bivalent rLP2086 vaccine in laboratory workers ≥18 to ≤65 years of age administered on a Month 0, 2, and 6 schedule. The study will recruit laboratory personnel (inclusive of Pfizer staff) who work directly with pathogenic Neisseria meningitidis in the context of the bivalent rLP2086 vaccine development program. The study will provide descriptive safety and immunogenicity data following vaccination of these individuals with bivalent rLP2086 vaccine.

The aim of the study was to describe the safety and antibody response to booster administration with Meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine in participants who received their first quadrivalent meningococcal Conjugate vaccine dose in the past 4-10 years. Primary Objective: To demonstrate the non-inferiority of the vaccine seroresponse of meningococcal serogroups A, C, Y, and W following the administration of a booster dose of MenACYW Conjugate vaccine compared to those observed following the administration of a booster dose of Menactra® in participants who were first vaccinated with 1 dose of a quadrivalent meningococcal vaccine 4 to 10 years before the booster dose. Secondary Objectives: To evaluate the vaccine seroresponse of meningococcal serogroups A, C, Y, and W measured using human serum bactericidal assay (hSBA) in serum specimens collected 6 days after vaccination in a subset of 120 participants. To evaluate the antibody responses (geometric mean titers) to serogroups A, C, Y, and W measured using hSBA on Day 0 (pre-vaccination) and Day 30 after vaccination. Observational Objectives: To describe the antibody titers against meningococcal serogroups A, C, Y, and W measured by hSBA assessed at Day 0, Day 6, and Day 30 days after vaccination. To describe the antibody responses to the meningococcal serogroups A, C, Y, and W before and 30 days after vaccination with MenACYW Conjugate vaccine or Menactra® measured by rabbit serum bactericidal assay (rSBA) in a subset of participants. To describe the safety profile of MenACYW Conjugate vaccine compared to that of a licensed Menactra® after booster vaccination.

This study is designed to assess the safety and immunogenicity of a single dose of Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (SP284) to support registration of the product in Japan. Primary Objective: To describe the seroprotection rate [% of subjects with serum bactericidal assay using baby rabbit complement (SBA-BR) ≥1:128] to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age Secondary Objectives: To describe the safety following receipt of SP284 vaccine in subjects 2 through 55 years of age To describe the immune responses to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age.

Human Papillomavirus (HPV) is a significant public health issue affecting nearly 14 million people in the United States. HPV can lead to cervical, oropharyngeal, anal, and penile cancers as well as genital warts.The purpose of this study is to test the comparative effectiveness of two interventions, AFIX only vs. AFIX + communication training, to increase Human Papillomavirus (HPV) vaccination rates among adolescent patients in outpatient clinic settings. Providers and staff at four pediatric practices will be randomized to receive an in-person AFIX consultation or an AFIX consultation combined with communication training and commitment poster displays. Provider and parent data will be collected via a tablet computer RedCap survey. Additional practice and provider level HPV vaccination rates will be collected via patient de-identified claims data. The results of this study could contribute to the existing body of literature that suggests provider recommendations and routine vaccination assessments are key to increasing HPV vaccination uptake. This project has the potential to lead to the implementation and dissemination of low resource interventions to increase HPV vaccination rates among children and adolescents.

The purpose of this study is to evaluate the safety of an investigational meningococcal B rLP2086 vaccine in adults and to obtain blood samples from immunized subjects for use in assay development.

The purpose of this study was to collect large volumes of matched pairs of pre- and post-vaccination sera from healthy subjects who administered GlaxoSmithKline (GSK) Biologicals' vaccine against meningitis- MenACWY vaccine (Menveo) or rMenB+OMV NZ vaccine (Bexsero), which serves for the development, qualification, validation, and maintenance of immunological assays which supports the preclinical research activities and clinical development of GSK Biologicals' vaccines. The safety of the subjects given one of the two vaccines (Bexsero or Menveo), as per the recommended dosage and schedule were assessed during their participation in the study.

The trial is an interventional, cluster-randomized trial to assess the impact of oral ciprofloxacin for household and community contacts of meningitis cases on the incidence of meningitis during an epidemic. The trial contains a nested sub-study ("resistance study") to assess the effect of a single dose of ciprofloxacin on the prevalence of fluoroquinolone-resistant enterobacteriaceae in the study area.

The primary objective is to evaluate the persistence of bactericidal antibodies in adolescent subjects who completed study V59P6 in which they received either Novartis Meningococcal (MenACWY) Conjugate Vaccine or Licensed polysaccharide Men ACWY vaccine (Menomune®). The study will also enroll age-matched subjects who have never received any other meningococcal vaccine (naïve subjects) to serve as an additional control group.

The primary immunogenicity objective is to assess and compare the immunogenicity of one dose of MenACWY to one dose of Menjugate given to healthy toddlers at 12 months of age as measured by the percentage of subjects with serum bactericidal titers directed against N. meningitidis serogroup C ≥ 1:8 obtained in the serum bactericidal assay using human complement (hSBA).
