Clinical Trial Summary

This two-stage study evaluates the immunogenicity, safety, and tolerability of the administration of VAQTA™ (Hepatitis A Vaccine, Inactivated) concomitantly with PedvaxHIB™ (Haemophilus B Conjugate Vaccine [Meningococcal Protein Conjugate]) and Infanrix™ (Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed, GlaxoSmithKline) versus the administration of VAQTA™ in healthy children 15 months of age at study entry.


Description:

In stage I, VAQTA™ given concomitantly with Infanrix™ and/or PedvaxHIB™ was evaluated.

In stage 2: Two (2) doses of the VAQTA™ vaccine were administered at least 6 months apart. Safety data was collected after each dose.

Intervention

Biological:
Comparator: VAQTA™
VAQTA™ (Hepatitis A Vaccine, Inactivated). Two intramuscular 0.5-mL doses of VAQTA™ were administered 24 weeks apart, with the second dose being administered prior to 24 months of age.
Comparator: Infanrix™
Infanrix™ (Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed, GlaxoSmithKline). One intramuscular 0.5-mL injection of Infanrix™ was administered at the first study visit.
Comparator: PedvaxHIB™
PedvaxHIB™ (Haemophilus B Conjugate Vaccine [Meningococcal Protein Conjugate]). One intramuscular 0.5-mL injection of PedvaxHIB™ was administered at the first study visit.

Outcome

Type Measure Description Time frame Safety issue
Primary Seropositivity Rate (SPR) to Hepatitis A SPR is the percent of participants with Hepatitis A antibody titers >= 10 milli-International Units/milliliter (mIU/mL), 4 weeks after dose 2 of VAQTA™ regardless of their initial serostatus. Antibody titers to Hepatitis A virus (HAV) were detected in participants' serum samples using an Enzyme Immunoassay (EIA). 4 weeks after dose 2 of VAQTA™ No
Primary Antibody Response Rate to Haemophilus Influenzae Type b (Hib) Antibodies to the Hib capsular polysaccharide (polyribosylribitol phosphate [PRP]) are assessed in participants serum using radioimmunoassay (RIA). The limit of detection (LOD) for the RIA is 6.60 ng/mL.
The antibody response rate is defined as the percentage of participants with anti-PRP titers >1.0 mcg/mL, 4 weeks postvaccination with PedvaxHIB™.
4 weeks postvaccination with PedvaxHIB™ No
Primary Number of Participants With Adverse Events (AE) Systemic and injection site AEs were collected from participants receiving
VAQTA™ concomitantly with Infanrix™ and PedvaxHIB™ or PedvaxHIB™ (Stage I)
VAQTA™ non-concomitantly with Infanrix™ and PedvaxHIB™ or PedvaxHIB™ (Stage I)
VAQTA™ administered alone (Stage II)
Safety data was collected on a standardized Vaccination Report Card (VRC)
following each dose. Participants returned the VRC after the safety follow-up period for each dose of VAQTA™. AEs determined by the investigator to be possibly, probably or definitely related to the vaccine are reported as Vaccine-related AE.
Days 1 to 14 after any dose of VAQTA™ for systemic AEs, and Days 1 to 5 after any dose of VAQTA™ for injection-site AEs Yes
Primary Geometric Mean Titers (GMTs) to Antibodies for the Pertussis Toxin (PT), Pertussis Filamentous Hemagglutinin Antibody (FHA), and Pertactin (PRN) Components of Infanrix™ GMTs for antibodies to PT, FHA, and PRN were measured in serum samples of participants vaccinated with Infanrix™.
IgG antibodies to PT were assessed using the anti-pertussis toxin enzyme-linked immunosorbent assay (anti-PT ELISA), with the LOD of 2.4 ELU/mL.
IgG antibodies to FHA were assessed using the anti-pertussis filamentous hemagglutinin enzyme-linked immunosorbent assay (anti-FHA ELISA), with the LOD of 2.0 ELU/mL.
IgG antibodies to PRN were assessed using the anti-pertussis pertactin enzyme-linked immunosorbent assay (anti-PRN ELISA), with the LOD of 3.3 ELU/mL.
4 weeks postvaccination with Infanrix™ No
