| NCT00197015 | Immunogenicity & Safety of Hepatitis A Vaccine Co-admin With a Measles/Mumps/Rubella & a Varicella Vaccine in Children | PHASE3 | COMPLETED | 1,474 | — | — | Oct 6, 2003 | Jun 9, 2009 | Jul 31, 2018 | 42 | United States |
Subjects are defined as being anti-HAV seropositive if their anti-HAV antibody concentration is ≥ 15 milli-International Units per milliliter (mIU/mL).
Subjects are defined as being anti-diphtheria, anti-tetanus and anti-PRP seroprotected if their anti-diphtheria and anti-tetanus antibody concentration is ≥ 0.1 International Units per milliliter (IU/mL) and if their anti-PRP antibody concentration is ≥ 1 microgram per milliliter (μg/mL), respectively.
Subjects are considered as being vaccine responders if they were initially seronegative and become seropositive (≥ 5 Enzyme Linked Immunosorbent Assay Units per Milliliter (EL.U/mL)), or were initially seropositive and have a 2-fold increase above pre-study concentrations.
Concentrations are given as geometric mean concentrations (GMCs) expressed as milli-international units per milliliter (mIU/mL).
Anti-HAV antibody cut-off value assessed include 15 milli-international units per milliliter (mIU/mL).
Seroconversion is defined as the appearance of antibodies with titers greater than or equal to the predefined cut-off value in the serum of subject seronegative before vaccination. Cut-off values assessed include 150 milli-international units per milliliter (mIU/mL) for anti-measles antibodies, 28 Effective Dose 50 (ED50) for anti-mumps antibodies and 1:5 for anti-varicella antibodies.
Vaccine response is defined as the appearance of antibodies with titers greater than or equal to the predefined cut-off value in the serum of subject seronegative before vaccination. Cut-off value assessed include 10 milli-international units per milliliter (mIU/mL).
