Immunogenicity and Safety of NBP608 Compared to Varivax in Healthy Children 12 Months to 12 Years of Age
- Conditions
- Varicella
- Interventions
- Biological: NBP608Biological: Varivax
- Registration Number
- NCT03114943
- Lead Sponsor
- SK Bioscience Co., Ltd.
- Brief Summary
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)

- Primary Outcome Measures
Name Time Method seroconversion rate by FAMA (Fluorescent Antibody to Membrane Antigen) assay 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
- Secondary Outcome Measures
Name Time Method VZV (Varicella Zoster Virus) antibody GMT(Geometric Mean Titer) measured by gpELISA (Glycoprotein Enzyme Linked Immunosorbent Assay) 6 weeks after IP(Investigational Product) vaccination VZV (Varicella Zoster Virus) antibody GMT(Geometric Mean Titer) measured by FAMA (Fluorescent Antibody to Membrane Antigen) assay 6 weeks after IP(Investigational Product) vaccination seroconversion rate by gpELISA (Glycoprotein Enzyme Linked Immunosorbent Assay) 6 weeks after IP(Investigational Product) vaccination \*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
