Brief Summary

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.

Detailed Description

This Protocol Posting has been updated following amendment of the Protocol, January 2010. The sections impacted are: study design and study endpoints.

  • A male or female between, and including, 18 and 40 years of age at the time of the first vaccination.
  • Written informed consent obtained from the subject.
  • Subject without medical history, clinical finding or laboratory finding, which, in the opinion of the investigator, could pose a safety concern or interfere with the protocol.
  • If the subject is female, and of childbearing potential, she agrees to use adequate contraception and not become pregnant for the duration of the study.
Exclusion Criteria
  • Pneumonia within 3 years prior to 1st vaccination.
  • Invasive Pneumococcal Disease within 3 years prior to 1st vaccination.
  • Use of any investigational or non-registered product other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period or participation to another pharmaceutical/vaccine study.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
  • Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccines, with the exception of the influenza vaccine which can be administered >14 days prior to or >14 days following vaccine doses 1 and 2.
  • Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus infection.
  • History of reaction or hypersensitivity to any component of the vaccine.
  • Any serious, uncontrolled disease likely to interfere with the study as determined by history, physical examination or laboratory screening, as per the judgment of the Investigator.
  • Inflammatory processes such as known chronic infections.
  • All past or current malignancies and lymphoproliferative disorders.
  • Laboratory evidence of haematological and biochemical abnormalities.
  • Acute disease at the time of enrolment/vaccination.
  • Pregnant or lactating female.
  • Female planning to become pregnant or planning to discontinue contraceptive precautions.
  • History of chronic alcohol consumption and/or drug abuse.
  • Other conditions that the principal investigator judges may interfere with study findings.
  • Previous vaccination for hepatitis B. As a portion of the subjects will be randomized to receive Engerix-B comparator, it is important that all subjects meet Engerix-B eligibility criteria.

Primary Outcome Measures
NameTimeMethod
Number of Subjects With Any Unsolicited Adverse Events (AE)During a 30-day (Days 0-29) follow up period after any vaccination

An unsolicited adverse event is any adverse event (i.e. any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms will be reported as an unsolicited adverse event.

Number of Subjects With Any Hematological Laboratory AbnormalitiesDuring a 7-day follow up period after vaccine dose 1 and 2 and at Days 180, 300 and 420.

Hematological parameters assessed in blood samples include red blood cells (RBC), white blood cells (WBC - including Basophils (BAS), neutrophils (NEU), lymphocytes (LYM), eosinophils (EOS) and monocytes (MON)), blood platelets (PLA) and Hemoglobin (HEM). Abnormalities reported include values outside the normal ranges.

This outcome presents results for BAS, NEU, LYM, EOS and MON. Time points were presented as before (Pre) or after (Post) Dose 1, 2 or 3.

Number of Subjects With Any Solicited Local and General SymptomsDuring a 7-day follow up period after any vaccination

Solicited local symptoms assessed were pain, redness and swelling. Any solicited local symptom was defined as occurrence of any solicited local symptom regardless of intensity grade.

Solicited general symptoms assessed were fatigue, gastrointestinal, headache, malaise, myalgia and temperature Any temperature was defined as oral temperature equal to or above (≥) 37.5 degrees Celsius (°C). For other symptoms: Any = any general symptom reported irrespective of intensity grade and relationship to vaccination.

Number of Subjects With Any Serious Adverse Events (SAEs)From Day 0 to Day 420

SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination.

Number of Subjects With Any Biochemical Laboratory AbnormalitiesDuring a 7-day follow up period after vaccine dose 1 and 2 and at Days 180, 300 and 420

Biochemical parameters assessed in blood samples include alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA) and urea (URE).

Abnormalities reported include values outside the normal ranges. Time points were presented as before (Pre) or after (Post) Dose 1, 2 or 3.

Secondary Outcome Measures
NameTimeMethod
Mean Number of Influenza-specific Cluster of Differentiation (CD) 8 T-cells.Prior to first vaccination (Day 0), at 14 days post vaccination 1 (Day 14) and 2 (Day 74) and at Day 480.

The mean number was calculated for CD8+ cells stimulated by protein D (PD), pneumococcal histidine triad D (PhtD) and pneumolysin toxoid (dPly) and expressing the following citokine combinations:

C1= at least interleukin 2 (IL2), tumor necrosis factor alpha (TNFa) and/or interferon-gamma (IFNg) and C2= at least interleukin 17 (IL17).

Concentrations of Antibodies Against Protein D (Anti-PD), Pneumolysin (Anti-Ply) and Pneumococcal Histidine Triad D (Anti-PhtD)Days 0, 30, 60, 90, 180 and 420.

Concentrations were given as Geometric Mean Concentrations (GMCs). The cut-off values were 112 Luminex Units per milliliter (LU/mL) for Anti-PD, 391 LU/mL for Anti-PhtD and 591 LU/mL for Anti-Ply.

Mean Number of Influenza-specific Cluster of Differentiation (CD) 4 T-cells.Prior to first vaccination (Day 0), at 14 days post vaccination 1 (Day 14) and 2 (Day 74) and at Day 480.

The mean number was calculated for CD4+ cells stimulated by protein D (PD), pneumococcal histidine triad D (PhtD) or pneumolysin toxoid (dPly), identified as producing T-lymphocyte Helper 1 cells (Th1) versus Th2 cytokines (interferon-gamma (IFN-g) and interleukin-13 (IL-13) respectively, as measured by intracellular staining (ICS) on Peripheral Blood Mononuclear Cells (PBMCs). The outcome presents results for cells producing the following combinations:

Th1=IFN-g, Th 2=IL13 and/or IL5 and Th17=IL17.
