Official title

A Phase III, Double-blind, Randomized, Multicenter, Multinational, Active-controlled, Non-inferiority Study to Evaluate Immunogenicity and Safety After the First and Second Doses of MG1111 (BARYCELA Inj.) in Healthy Children Aged 12 Months to 12 Years

Overview

This clinical study aims to evaluate the safety and immune response of MG1111, in healthy children compared to VARIVAX. The study will follow participants for 42 days after receiving two doses, with additional follow-ups for up to 10 years to monitor varicella infection.

Interventions

  • Biological MG1111 (Barycela inj.)
    MG1111 (Barycela inj.)
  • Biological VARIVAX™
    Varivax™

Primary outcome measures

  • Proportion of participants who achieved seroconversion at 42 days after second vaccination [Time frame: 42 days after second vaccination]
Secondary outcome measures (3)
  • Percentage of participants reporting local and systemic solicited adverse events during the first 7 days after each vaccination with MG1111 or VARIVAX [Time frame: 7 days after each vaccination]
  • Percentage of participants reporting unsolicited adverse events during the first 42 days after each vaccination with MG1111 or VARIVAX [Time frame: 42 days after each vaccination]
  • Percentage of participants reporting serious adverse events until 6 months after second vaccination with MG1111 or VARIVAX [Time frame: 6 months after second vaccination]
