Assess the Safety and Immunogenicity of NDV-HXP-S Vaccine in Thailand

Summary

This study will be conducted in 2 phases. Phase 1 designed to evaluate safety, tolerability and immunogenicity COVID-19 vaccine (NDV-HXP-S) administered at different doses levels (1, 3, and 10 µg) without adjuvant, and at two different dose levels (1 and 3 µg) with the adjuvant CpG 1018 among healthy adults, (age 18-59 years) (210 subjects). Subjects will receive 2 doses of assigned investigational product (IP) on D1 and D29 (V1 and V3), and be assessed in clinic for safety and reactogenicity at 7 days after each vaccination (day 1 as day vaccination). An interim analysis of Phase 1 data will be conducted as the basis for decisions about advancement to Phase 2 of the study and about treatment group down selection. Phase 2 (250 subjects) will include approximately one-third subjects with age 60-75 years.
