Active clinical trials for "Pneumococcal Infections"

This is a Phase 1 first-in-human, randomized, controlled, observer-blinded study with a 2-arm parallel design. Healthy adults aged 18 to 49 years of age with no history of pneumococcal vaccination will be randomized equally to receive either a single intramuscular dose of multivalent pneumococcal conjugate vaccine or a licensed tetanus, diphtheria, acellular pertussis combination vaccine (Tdap) (control group).

This is a Phase 2, randomized, double-blinded study with a 2-arm parallel design. Healthy adults aged 60 through 64 years of age with no history of pneumococcal vaccination will be randomized equally to receive either a single intramuscular dose of multivalent pneumococcal conjugate vaccine followed 1 month later with a dose of saline or Prevnar 13 followed 1 month later with a dose of PPSV23 (control group).

Similar to children, adults frequently visit outpatient clinics to get two or more kinds of vaccines at the same time: pneumococcal vaccine, influenza vaccine, Td (diphtheria and tetanus) vaccine, HPV (human papilloma virus) vaccine, meningococcal vaccine, zoster vaccine, etc. This study is intended to evaluate the immunogenicity and safety of concomitant administration of 23-valent pneumococcal polysaccharide vaccine (PPV23, Prodiax) and MF59 adjuvanted trivalent influenza vaccine in the elderly subjects aged ≥65 years.

The goal of this study is to evaluate the safety, tolerability, and immunogenicity of the Pneumococcal Conjugate Vaccines (PCVs) V114 and Prevnar 13™ in healthy infants switched from Prevnar 13™ to V114 during the four-dose PCV immunization schedule.

The primary objectives are to evaluate the safety and tolerability of V114 and to compare the serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) across 3 different lots of V114. The primary hypothesis is that all 3 lots of V114 are equivalent as measured by the serotype-specific OPA GMTs for 15 serotypes in V114 at 30 days postvaccination.

This study will evaluate the safety and tolerability and immunogenicity of V114 when administered to 2-month old infants. The primary hypotheses are: 1) V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes between V114 and Prevenar 13™ based on response rates at 30 days post toddler dose (PTD); 2) V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on the response rates at 30 days PTD; 3) V114 is non-inferior to Prevenar 13™ for the 13 shared serotypes between V114 and Prevenar 13™ based on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobin G (IgG) geometric mean concentrations (GMCs) at 30 days PTD; and 4) V114 is superior to Prevenar 13™ for the 2 serotypes unique to V114 based on anti-PnPs serotype-specific IgG GMCs at 30 days PTD.

A phase 3, randomized, double-blind trial to evaluate the safety and immunogenicity of a 20-valent pneumococcal conjugate vaccine in pneumococcal vaccine-naïve adults 60 years of age and older in Japan, Korea, and Taiwan

The purpose of this study is to evaluate the safety and tolerability of three dose levels of ASP3772 in comparison to the active comparator Prevnar 13® (PCV13) in toddlers who have previously been administered the routine three-dose series of PCV13. This study will also evaluate the immunogenicity (production of an immune response) of three different dose levels of ASP3772 in comparison to the active comparator PCV13 in toddlers who have previously been administered the routine three-dose series of PCV13.

The 23-valent pneumococcal Polysaccharide vaccine (23vPPV) has been developed for children and adults to prevent pneumococcal diseases such as pneumonia (inflammation of the lungs), meningitis (inflammation of the brain lining), and septicemia (blood poisoning) since 2006 in China. Also, the trivalent influenza vaccine (TIV) is frequently administered to the children and adults. The main objective of this study is to show that both vaccines can safely be administered together without affecting the immune response of protecting against disease.

The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of GSK Biologicals' 10Pn-PD-DiT vaccine in children aged between 2 and 17 years of age having asplenia, splenic dysfunction or complement deficiencies. In addition, this study will include an age-matched control group of healthy children aged 24-59 months in order to descriptively compare the immunogenicity of 10Pn-PD-DiT vaccine in the at-risk population to that of the general, healthy population one month after each pneumococcal vaccination.
