Study of Two Formulations of GSK Biologicals' Varicella Vaccine

May 9, 2018 updated by: GlaxoSmithKline

Study of Two Formulations of GSK Biologicals' Varicella Vaccine Given as a 2-dose Course in the Second Year of Life

The aim of this study is to evaluate a modified formulation of GSK Biologicals' live attenuated varicella vaccine. In vivo pre-clinical data show this change has no negative impact on vaccine safety. This present study is undertaken to rule out any negative impact on the immunogenicity and safety of GSK Biologicals' live attenuated varicella virus vaccine.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Antibody Titers Against Varicella Zoster Virus (VZV)
Time Frame: At 43-57 days after the first vaccine dose (Week 6)
Antibody titers have been assessed by immunofluorescence assay (IFA) and presented as geometric mean titers (GMTs), for initially seronegative subjects [with anti-VZV titer below (<) 1:4].
At 43-57 days after the first vaccine dose (Week 6)
Antibody Concentrations Against Varicella Zoster Virus (VZV)
Time Frame: At 43-57 days after the first vaccine dose (Week 6)
Antibody concentrations have been assessed by enzyme-linked immunosorbent assay (ELISA), presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL), for initially seronegative subjects [with anti-VZV concentration below (<) 25 mIU/mL].
At 43-57 days after the first vaccine dose (Week 6)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Seroconverted Subjects for Varicella Antibodies
Time Frame: At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Seroconversion/seroresponse (considering the IFA data) was defined as the appearance of anti-VZV antibodies [i.e. titer/concentration greater than or equal to (≥) the assay cut-off value of 1:4] in the sera of subjects who were seronegative before vaccination.
At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Number of Subjects With Anti-VZV Antibody Concentrations Above Cut-off Values
Time Frame: At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Anti-VZV antibody concentrations greater than or equal to (≥) the assay cut-off values of: 25 mIU/mL, 50 mIU/mL and 75 mIU/mL have been assesssed by ELISA, in the sera of subjects who were seronegative before vaccination.
At 43-57 days post-Dose 1 (Week 6) and 86-114 days post-Dose 2 (Week 12)
Antibody Titers Against Varicella Zoster Virus (VZV)
Time Frame: At 86-114 days after the second vaccine dose (Week 12)
Antibody titers have been assessed by immunofluorescence assay (IFA) and presented as geometric mean titers (GMTs), for initially seronegative subjects [with anti-VZV titer below (<) 1:4].
At 86-114 days after the second vaccine dose (Week 12)
Antibody Concentrations Against Varicella Zoster Virus (VZV)
Time Frame: At 86-114 days after the second vaccine dose (Week 12)
Antibody concentrations have been assessed by enzyme-linked immunosorbent assay (ELISA), presented as geometric mean concentrations (GMCs) and expressed in milli-international units per milliliter (mIU/mL), for initially seronegative subjects [with anti-VZV concentration below (<) 25 mIU/mL].
At 86-114 days after the second vaccine dose (Week 12)
Number of Subjects With Any and Grade 3 Solicited Local Symptoms
Time Frame: During the 4-day (Days 0-3) post-vaccination period following each dose
Assessed solicited local symptoms were pain, redness and swelling. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 20 millimeters (mm) of injection site.
During the 4-day (Days 0-3) post-vaccination period following each dose

Time Frame: During the 43-day (Days 0-42) post-vaccination period following each dose
Assessed solicited general symptoms were fever [defined as axillary fever ≥ 37.5 degrees Celsius (°C)] and generalized rash. Any = occurrence of the symptom regardless of intensity grade or relationship to vaccination. Grade 3 fever = temperature above (>) 39.0°C after vaccination. Grade 3 rash = more than (>) 150 lesions. Related = considered by the investigator to be causally related to the study vaccination.
During the 43-day (Days 0-42) post-vaccination period following each dose
Number of Subjects With Any Unsolicited Adverse Event (AE)
Time Frame: Within the 43-day (Days 0-42) post-vaccination period following each dose
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any was defined as an adverse event (AE) reported in addition to those solicited during the clinical study. Any solicited symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.
Within the 43-day (Days 0-42) post-vaccination period following each dose
Number of Subjects With Serious Adverse Events (SAEs)
Time Frame: From Day 0 up to study end (Day 86-114)
Serious adverse events (SAEs) assessed include medical occurrences that results in death, are life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity or is a congenital anomaly/birth defect in the offspring of a study subject.
From Day 0 up to study end (Day 86-114)
