Safety and Immunogenicity of High-dose IN-B001 in Healthy Subjects

Phase 1
Conditions
Hand, Foot and Mouth Disease
Interventions
Biological: IN-B001 Bivalent C dose
Biological: IN-B001 EV71 A dose
Biological: IN-B001 CVA16 B dose
Biological: Placebo
Registration Number
NCT04637919
Lead Sponsor
HK inno.N Corporation
Brief Summary

This study aims to evaluate the safety and immunogenicity of high-dose IN-B001 after administration in healthy subjects

Detailed Description

Enterovirus 71(EV71) and coxsackievirus A16(CVA16) are major causes of Hand-foot-and-mouth disease (HFMD) occurring in pediatric population. Although EV71 vaccine has been licensed in China, vaccine for CVA16-associated HFMD is currently not available anywhere. The purpose of this phase I study is to evaluate the safety and immunogenicity of EV71/CVA16 bivalent vaccine in healthy adults.
