简要总结
The objective of our study is to evaluate safety, tolerability, and immunogenicity of COVID-19 preventive DNA vaccine in healthy volunteers.
详细描述
This clinical study is phase 1/2a clinical trial to evaluate safety, tolerability, and immunogenicity of COVID-19 preventive vaccine by intramuscularly administration in healthy volunteers.
Phase 1 of this study is designed as single arm, open-labeled and a total of 20 subjects will be enrolled. Phase 2a of study is designed as randomized, double-blind, placebo controlled and a total of 150 subjects are planned to be enrolled.
