Clinical Trial Summary

This is an open label, phase III trial - immunobridging study. There will be only 1 group in the study. All subjects (12 to 17 years old) will receive INAVAC 5 µg dose. The vaccine will be administered with 2-dose schedule, intramuscularly, with 28 day interval. All subjects will be followed for 12 months.

INAVAC is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this study will be the first phase III in adolescents.

Description:

This is an open label, phase III trial - immunobridging study. There will be only 1 group in the study. All subjects (12 to 17 years old) will receive INAVAC 5 µg dose. The vaccine will be administered with 2-dose schedule, intramuscularly, with 28 day interval. All subjects will be followed for 12 months.

This study will have three interim and one full analysis The main focus is immunogenicity and safety or reactogenicity issues.

Data Safety Monitoring Board will be commissioned for this study to evaluate safety data over the study period and to review any events that meet a specific study pausing rule or any other safety issue that may arise. They will review the 7 and 28 days safety data following the first dose of vaccine, and then the 7 and 28 days after the second dose. The immunogenicity data will be evaluated until 12 months after the second dose.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Vaccine Neutralizing Antibody Profile	SARS-CoV-2 neutralizing titers in serum measured by a virus neutralization assay, at 28 days after two doses vaccination of INAVAC in healthy adolescents age 12 to 17 years old, compared with previous results in adults with two doses of similar vaccine (phase 3 in adults).	28 days after two doses vaccination of INAVAC.
Secondary	Incidence of Adverse Events	Solicited - clinical (local and systemic) adverse events for 30 minutes, 24 hours, 7 and 28 days after the first and second vaccination, and then 3, 6, and 12 months after the second injection of INAVAC in healthy adolescents age 12 to 17 years old, compared with previous results in adults with two doses of similar vaccine (phase 3 in adults).; Unsolicited adverse events for 30 minutes, 24 hours, 7 and 28 days after the first and second vaccination, and then 3, 6, and 12 months after the second injection of INAVAC in healthy adolescents age 12 to 17 years old, compared with previous results in adults with two doses of similar vaccine (phase 3 in adults).; Serious adverse event (SAE) throughout the study (from the first vaccination).	30 minutes, 24 hours, 7 and 28 days following the first dose and 30 minutes, 24 hours, 7 and 28 days, 3, 6 and 12 months after the second doses of INAVAC
Secondary	Humoral Immunogenicity - The Neutralizing Antibody Titers in Serum	Evaluate SARS-Cov-2 neutralizing titers in serum measured by virus neutralization assay at 3, 6, and 12 months, following vaccination with two doses of INAVAC in healthy adolescents age 12 to 17 years old, compared with previous results in adults with two doses of similar vaccine (phase 3 in adults).	3, 6, and 12 months, following vaccination with two doses of INAVAC
Secondary	Humoral Immunogenicity - Levels of SARS-CoV-2 Binding Antibodies by CLIA	SARS-CoV-2 binding antibodies measured by CLIA: analysis of antibodies binding to the SARS-CoV-2 S-protein.	28 days, 3, 6, and 12 months after the second vaccination of INAVAC
Secondary	Cellular Immunogenicity Profile	Th1 immune responses assessed by Flow cytometri; Th2 immune responses assessed by Flow cytometri	28 days, 3, 6, and 12 months, following vaccination with two doses of INAVAC
Secondary	Persistence of Antibody Level	Evaluate the persistence of antibody level over time for 12 months after second injection.	12 months after the second injection
Secondary	Whole Genome Sequencing (WGS) of SARS-CoV-2	Whole genome sequencing (WGS) of S protein of SARS-CoV-2 virus from all positive Covid-19 cases	Throughout the study, an average of 1 year
