Active clinical trials for "Streptococcal Infections"

The purpose of this study is to assess the immune memory induced by primary and booster vaccination with pneumococcal conjugate vaccine GSK1024850A in the first year of life through evaluation of the immune responses following vaccination with a booster dose of pneumococcal conjugate vaccine GSK1024850A in the fourth year of life and to assess immune responses following vaccination with a single dose of pneumococcal conjugate vaccine GSK1024850A in age-matched unprimed children. The study also aims to assess the antibody persistence in the fourth year of life following primary and booster vaccination with pneumococcal conjugate vaccine GSK1024850A in the first year of life. The study is also designed to evaluate the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following a 2-dose vaccination with pneumococcal conjugate vaccine GSK1024850A in the fourth year of life. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = 00307034)

The purpose of the present study is to demonstrate that the changes in the manufacturing process for the commercial lot of the pneumococcal conjugate vaccine GSK1024850A have no clinical impact and that the immune responses are non-inferior to the immune responses induced by the clinical lot. The study will be conducted in Singapore and Malaysia.

The purpose of the study is to evaluate the safety and reactogenicity of Synflorix™ (GSK 1024850A) given as a 3-dose primary immunization course when co-administered with Infanrix hexa™ vaccine at 2, 3 and 4 months of age in infants in Vietnam.

The purpose of this trial is to assess the safety, reactogenicity and immunogenicity of GSK Biologicals' pneumococcal conjugate vaccine GSK1024850A when administered either as a booster dose or as a two dose catch-up vaccination in the second year of life to the Nigerian subjects previously enrolled in the primary vaccination study NCT00678301. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00678301).

This study will assess the safety, reactogenicity and immunogenicity of different formulations of GSK Biologicals' pneumococcal vaccine 2189242A when administered alone or in combination with the 10-valent pneumococcal conjugate vaccine (GSK1024850A vaccine) as a 2-dose primary vaccination course followed by a booster dose in healthy children aged 12-23 months at the time of first vaccination. Considering that febrile reactions are frequently observed following pneumococcal vaccination, usually co-administered with other routine paediatric vaccines, the primary study objective will focus on evaluating the increase in grade 3 fever (i.e. rectal temperature >40.0°C).

This protocol posting deals with objectives & outcome measures of the extension phase up to 48-50 months post booster vaccination, to assess long-term antibody persistence in children at around 30, 42 and 66 months of age, who received previously 4 doses of pneumococcal conjugate vaccine. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = 00307554). This Protocol posting has been updated in order to comply with the FDA AA (Sep 2007).

The purpose of this study is to evaluate the reactogenicity, safety and immunogenicity of a booster (fourth) dose of pneumococcal vaccine GSK1024850A when co-administered with Hiberix at 12-18 months of age, in children primed with the same vaccines in primary study NCT00680914.

Evaluate lot-to-lot consistency, safety and reactogenicity of 3 doses of GSK Biologicals' 10-valent pneumococcal conjugate vaccine and non-inferiority with respect to Prevenar.

This study will evaluate safety, reactogenicity and immunogenicity of GSK Biologicals' pneumococcal conjugate vaccine compared to Prevenar™ when co-administered with DTPw-HBV/Hib and OPV or IPV vaccines, according to 2 different schedules: 6-10-14 weeks or 2-4-6 months of age. The study has 2 groups. One group of subjects will receive a 3-dose primary vaccination with the GSK Biologicals' pneumococcal conjugate vaccine (three different lots will be used and randomly allocated). The 2nd group of subjects will receive a 3-dose primary vaccination with Prevenar™. All children will receive concomitantly DTPw-HBV/Hib and OPV or IPV vaccines. This protocol posting deals with objectives & outcome measures of the primary study. The objectives & outcome measures of the Booster study are presented in a separate protocol posting (NCT number =00547248).

Antibody deficiencies and complement deficiencies are the most frequent Primary immunodeficiencies (PIDs) in adults, and are associated with greatly increased susceptibility to recurrent and/or severe bacterial infections - especially upper and lower respiratory tract infections and meningitis. The literature data suggest that PIDs are under-diagnosed in adults. The current European and US guidelines advocate screening adults for PIDs if they present recurrent benign especially upper and lower respiratory tract infections, or if they have experienced at least two severe bacterial infections and/or have a recurrent need for intravenous antibiotics. The objective of the demonstrate the interest of PIDs screening in adult patients who present such recurrent infections and/or after the first severe bacterial infection, especially when the patients do not present with known, etiologically relevant comorbidities.
