Immunogenicity and Safety of NBP608 Compared to Varivax in Healthy Children 12 Months to 12 Years of Age

May 6, 2019 updated by: SK Bioscience Co., Ltd.

A Multi-national, Multi-center, Randomized, Double Blinded, Parallel-group Study to Assess the Immunogenicity and Safety of NBP608 Compared to Varivax in Healthy Children 12 Months to 12 Years of Age

This study assesses non-inferiority by comparing seroconversion rate of NBP608 to Varivax which are indicated for active immunization for prevention of varicella. Total of 488 subjects (244 subjects per treatment arm) of 12 months to 12 years of age are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned.

Detailed Description

This is a multi-national, multi-center, randomized, double blinded, parallel-group study to assess the Immunogenicity and safety of NBP608 compared to varivax which are indicated for active immunization for the prevention of varicella. Total of 488 subjects of 12 months to 12 years of age are enrolled, and each subject is administered with single dose of vaccine which is randomly assigned in 1:1 ratio. Stratified randomization for age group is used to achieve the balance of treatment assignment within age strata.

Total of four visits are scheduled including two visits via telephone contact. Blood sampling is conducted for immunogenicity assessment before and 6 weeks after vaccination at Visit 1 and Visit 3 respectively. Safety is monitored 1 week, 6 weeks and 26 weeks after vaccination through Visit 2*, Visit 3 and Visit 4* (* telephone contact)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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
seroconversion rate by FAMA (Fluorescent Antibody to Membrane Antigen) assay
Time Frame: 6 weeks after IP(Investigational Product) vaccination
*FAMA(Fluorescent Antibody to Membrane Antigen) Seroconversion Rate: the rate of subjects who are converted from seronegative with FAMA(Fluorescent Antibody to Membrane Antigen) VZV(Varicella Zoster Virus) antibody titer < 1:4 before IP(Investigational Product) vaccination to seropositive with FAMA(Fluorescent Antibody to Membrane Antigen) VZV(Varicella Zoster Virus) antibody titer ≥ 1:4 at 6 weeks post-vaccination
6 weeks after IP(Investigational Product) vaccination

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.

*gpELISA(Glycoprotein Enzyme Linked Immunosorbent Assay) Seroconversion Rate : the rate of subjects who are converted from seronegative with < 50mIU/mL before IP(Investigational Product) vaccination to seropositive with ≥ 50mIU/mL at 6 weeks post-vaccination
6 weeks after IP(Investigational Product) vaccination

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
