Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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)
