InfectionsStreptococcal1 more

The aim of this study is to assess the effectiveness of GSK Biologicals' pneumococcal conjugate vaccine (GSK1024850A) in preventing invasive disease caused by S. pneumoniae or H. influenzae and in reducing occurrence of hospital-diagnosed pneumonia cases, tympanostomy tube placement and outpatient antimicrobial prescriptions in children starting vaccination below 18 months of age. These data will be collected from the national registers and will be analyzed in combination with data collected for subjects enrolled in a large scale cluster-randomized study 111442. The study will also assess the immune response to the GSK1024850A vaccine and the impact of the vaccine on occurrence of acute otitis media, carriage, safety in children starting vaccination below 18 months of age.

The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of Indian infants with pneumococcal conjugate vaccine GSK1024850A co-administered with a diphtheria, tetanus, whole cell pertussis (DTPw)-combined vaccine during the first 4 months of life. The study will be conducted in India.

Humoral Determinants of Immunity to Pneumococcal Infection

PneumoniaPneumococcal Infections2 more

The purpose of this study is to determine whether there are differences in the level of antibody to capsular polysaccharides of S. pneumoniae or the physiological activity of such antibody after vaccinating patients who have recovered from pneumococcal pneumonia with pneumococcal polysaccharide vaccine (Pneumovax) or conjugate pneumococcal vaccine (Prevnar).

A Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 When Administered Concomitantly...

PneumoniaPneumococcal

This a study of V116 in adults ≥50 years of age who concomitantly received Influenza vaccine. The primary objectives of this study are to evaluate the safety, tolerability, and immunogenicity of V116 when administered concomitantly with Quadrivalent Influenza vaccine (QIV) compared with V116 administered sequentially with QIV. The primary hypotheses state that immune responses to V116 and to QIV are non-inferior when administered concomitantly as compared with sequential administration as measured by serotype-specific opsonophagocytic activity (OPA) and hemagglutination inhibition (HAI) geometric mean titers (GMTs) at 30 days postvaccination.

Immunogenicity and Safety of PCV13 and Fluad in Adults Aged ≥60 Years

InfluenzaStreptococcus Pneumoniae

Recent reviews have highlighted the unpredictability and complexity of immune interference when multivalent conjugate vaccines are co-administered with other pediatric vaccines. It has become evident that the likelihood of immune interference (in response to conjugated- or co-administered antigens) increases in proportional to the number of glyco-conjugates (valencies) and dosages of carrier proteins. There are many kinds of carrier proteins: tetanus toxoid (TT), diphtheria toxoid (DT), CRM197 (non-toxic variant of DT), OMP (complex outer-membrane protein mixture from Neisseria meningitidis) and non-typeable Hemophilus influenza-derived protein D. Among them, TT is a more potent inducer of T-helper immunity, but carrier-induced-epitopic suppression (dose-dependent carrier antibody and carrier B cell dominance) may occur with TT. In comparison, DT and CRM197 are weaker B-cell immunogens, but apparently trigger more T-regulatory mechanism. Recent pediatric studies of PCV13 co-administered with DTaP vaccines showed 6B GMT (geometric mean titer) to be somewhat reduced compared to the results with PCV13 alone. 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. PCV13 has limited co-administration information for adjuvanted influenza vaccine. This study is designed to evaluate the immunogenicity and safety of PCV13 and MF59-adjuvanted influenza vaccine (Fluad) after concomitant administration in adults aged 60 years or older.

Safety, Tolerability and Immunogenicity of V114 in Healthy Adults and Infants (V114-004)

Streptococcus Pneumoniae InfectionPneumococcal Infections

This study is designed to assess the safety, tolerability, and immunogenicity of 5 different formulations of V114 in healthy adults and infants. Adults only will be enrolled in Period 1 and infants only will be enrolled in Period 2; Period 1 will complete prior to the start of Period 2.

Pneumococcal Vaccination of Multiple Myeloma Patients on Novel Agents

Multiple MyelomaPneumococcal Infection2 more

Multiple myeloma is an incurable blood cancer of plasma cells that occurs in older individuals. Novel agents (proteasome inhibitors, immunomodulatory agents) have substantially improved the overall response rates, progression-free survival and overall survival in patients with multiple myeloma. Patients with multiple myeloma are at high risk of developing life-threatening Streptococcus pneumoniae infections, while clinical efficacy and safety of conjugate pneumococcal vaccines in multiple myeloma patients receiving novel agents have not been studied before. The main aim of this study is to assess the clinical efficacy and safety of 13-valent pneumococcal conjugate vaccine in multiple myeloma patients treated with novel agents.

An Epidemiological Survey to Establish the Spectrum of Circulating Serotypes of S. Pneumoniae, in...

PneumoniaPneumococcal2 more

Pneumococcal conjugate vaccine was added to the National Immunization Program in Russia in 2014 which could affect the changes in pneumococcal serotypes in growing population. The purpose of this study is to determine the spectrum of serotypes of S. pneumoniae in patients older 18-years: in healthy carriage, in patients with non-invasive and invasive forms of pneumococcal infection. The patients will be divide into several groups: 18-64-years old, 65 years old and older, immunocompromised patients, immunocompetent patients with concomitant diseases and patients from restricted organized collectives. This study is designed to meet the following objectives: To estimate the spectrum of serotypes of S. pneumoniae in adult population in different regions of Russia.

Streptococcus PneumoniaeHaemophilus Influenzae

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of 2 formulations of a non-typable Haemophilus influenzae and pneumococcal candidate vaccine in young adults. Subjects will be vaccinated 2 times in an observer-blind manner with an interval of 2 months. The subjects receiving Engerix-B will receive in an open-manner a third dose of the vaccine at Month 6. The protocol posting has been updated following a protocol amendment.

InfectionsStreptococcal1 more

The aim of this study is to assess the immune response, safety and reactogenicity following administration of an additional dose of a pneumococcal conjugate vaccine at approximately 4 years of age in children previously vaccinated with 3 primary doses of GSK 1024850A or Prevenar™ vaccine within the first 6 months of life and a booster dose of plain polysaccharide pneumococcal (Pneumovax 23™) vaccine at 11-14 months of age. Antibody persistence will also be assessed at approximately 4 years of age in children previously vaccinated with 3 doses of either GSK 1024850A or Prevenar™ vaccine followed by a booster dose of Pneumovax 23™. This protocol posting deals with objectives & outcome measures of the extension phase at year 4. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT 00307541). The objectives & outcome measures of the booster phase are presented in a separate protocol posting (NCT 00333450).
