5. Study Description
Brief Summary
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen that causes a coronavirus-associated acute respiratory disease called coronavirus disease 19 (COVID-19), which is spreading all over the world. This virus can cause acute respiratory distress syndrome (ARDS) with a high fatality rate. In this phase I first-in-human clinical trial, healthy volunteers in two dose cohorts will be vaccinated Lyophilized COVID-19 mRNA Vaccine (RH109) The aim of the study is to assess the safety, reactogenicity and Immunogenicity of the candidate vaccine and to characterize its immunogenicity.
Detailed Description
Participants will be enrolled into 2 ascending dose (RH109 low-dose 25 μg, high-dose 50 μg) cohorts randomly. Approximately 24 eligible participants, 12 for each cohort, will be randomized with a 3:1 ratio (RH109 : Placebo). The study will progress in a sequential manner, with the low-dose cohort being enrolled and dosed first. Dose escalation from low-dose to high-dose cohort is contingent on a review of safety data of the low-dose cohort through to 7 days following the vaccination by a Safety Monitoring Committee (SMC)
