Immunogenicity and Safety Study of Proquad® and Infanrix® Hexa When Administered Concomitantly (V221-035)

Primary Objective:

* To demonstrate that ProQuad® can be administered concomitantly with a booster dose of Infanrix® hexa to healthy children 12 to 23 months of age without impairing either the antibody response rates to measles, mumps, rubella, varicella, hepatitis B and Haemophilus influenzae type b; or to the 3 pertussis antibody titres measured at 42 days following vaccination.

Secondary Objectives:

* To describe the antibody titres and the antibody response rates to measles, mumps, rubella, varicella, diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b as measured at 42 days following vaccination by an Infanrix® hexa primary series schedule and all data are pooled. * To evaluate the safety profile of ProQuad® when administered concomitantly with a booster dose of Infanrix® hexa by an Infanrix® hexa primary series schedule and all data are pooled.

  • For Italy: Primary vaccination with the combined diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b vaccine Infanrix® hexa as a 2-dose schedule, with receipt of the second dose ≥ 6 months prior to inclusion
  • For Germany: Primary vaccination with the combined diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b vaccine Infanrix® hexa as a 3-dose schedule, with receipt of the third dose ≥ 6 months prior to inclusion
  • Consent form signed by parent(s) according to local regulations or by the legal representative properly informed about the study
  • Parent(s)/legal representative able to understand the protocol requirements and to fill in the Diary Card.

Exclusion criteria

  • Prior receipt of measles, mumps, rubella and/or varicella vaccine either alone or in any combination
  • Any recent (<= 30 days) exposure to measles, mumps, rubella, varicella and/or zoster
  • Receipt of any other diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and/or Haemophilus influenzae type b containing vaccine (either alone or in any combination) than Infanrix® hexa
  • Any recent (<= 3 days) history of febrile illness
  • Any severe chronic disease

  • Any recent (<= 30 days) receipt of an inactivated or a live non-study vaccine or scheduled non-study vaccination through Visit 2
  • Any medical condition which, in the opinion of the investigator, might interfere with the evaluation of the study objectives
  • Any recent (≤30 days) participation or scheduled participation in any other clinical trial through Visit 2

Treatment and study plan

ProQuad®

Biological

Participants received a 0.5 mL subcutaneous injection of ProQuad® containing the following live attenuated virus strains: measles virus Enders' Edmonston strain (≥3.00 log10 50% cell culture infectious dose [CCID]50), mumps virus Jeryl Lynn™ (Level B) strain (≥4.30 log10 CCID50), rubella virus Wistar RA 27/3 strain (≥3.00 log10 CCID50), and varicella virus Oka/Merck strain (≥3.99 log10 plaque-forming units [PFU]).

Infanrix® hexa

Biological

Participants received a 0.5 mL intramuscular injection of Infanrix® hexa containing the following: diphtheria toxoid (≥30 IU), tetanus toxoid (≥40 IU), 3-component acellular pertussis (pertussis taxoid, filamentous haemagglutinin, and pertactin) (25 ug), Hepatitis B surface antigen recombinant (S protein) (10 ug), inactivated poliovirus types 1-3 (type 1: 40 D-antigen units; type 2: 8 D-antigen units; type 3: 32 D-antigen units), and Haemophilus influenzae type B (Hib) polysaccharide conjugate to tetanus toxoid (20-40 ug).

Primary outcomes

  1. Percentage of Participants Meeting Antibody Response Rate Criteria to Measles, Mumps, Rubella, and Varicella

    Time frame: Day 42

    The percentage of participants with seronegative baseline values who met antibody response criteria in Arm 1: ProQuad® + Infanrix® hexa and Arm 2: ProQuad® was determined. Post-vaccination antibody response and baseline seronegativity criteria were as follows: measles antibody titre ≥255 mIU/mL in participants with baseline titre <255 mIU/mL; mumps antibody titre ≥10 ELISA Ab units/mL in participants with baseline titre <10 ELISA Ab units mL; rubella antibody titre ≥10 IU/mL in participants with baseline titre <10 IU/mL; varicella antibody titre ≥5 gpELISA units/mL in participants with baseline titre <1.25 gpELISA units/mL. Measles, mumps and rubella antibody levels were determined using enzyme-linked immunosorbent assay (ELISA) and varicella antibody levels were determined with glycoprotein-based ELISA (gpELISA).

  2. Percentage of Participants Meeting Post-vaccination Antibody Response Rates to Hepatitis B and Haemophilus Influenzae Type B

    Time frame: Day 42

    The percentage of participants with seronegative baseline values who met antibody response criteria in Arm 1: ProQuad® + Infanrix® hexa and Arm 3: Infanrix® hexa was determined. Post-vaccination antibody response and baseline seronegativity criteria were as follows: Hepatitis B antibody titre ≥10 IU/mL and Haemophilus Influenzae Type b antibody titre ≥1 ug/mL. Hepatitis B antibody levels were determined using anti-HBs ORTHO ECi Immunodiagnostic Assay. Haemophilus Influenzae Type b antibody (anti-polyribosylribitol phosphate [PRP]) levels were determined with radioimmunoassay (RIA) or with enzyme immunoassay (EIA).

  3. Post-vaccination Geometric Mean Titres (GMT) to Pertussis

    Time frame: Day 42

    The GMT to pertussis were compared in Arm1: ProQuad® + Infanrix® hexa and Arm 3: Infanrix® hexa. Anti-pertussis toxin (anti-PT), anti-filamentous hemagglutinin (anti-FHA), and anti-pertactin (anti-PRN) were determined using ELISA on solid phase based on sandwich principle.
