简要总结
Determine safety and tolerability and immungenicity of investigational vaccine ARCT-021 in healthy adult volunteers.
详细描述
Randomized, double blinded (study site staff, subjects and Sponsor), placebo controlled, adaptive, ascending dose study evaluating administration of ARCT-021 in healthy adult subjects. 0.9% sterile saline will serve as a placebo control. Study drug (ARCT-021 or control) will be administered as an intramuscular (IM) injection. The study comprises two parts. In the Phase 1 part escalating dose levels given as a single injection to younger adults (21 to 55 years) will be evaluated sequentially. Two dose levels will be further evaluated in the Phase 2 part of the study in two expansion cohorts in younger adults (21 to 55 years) and in two elderly subject (56 to 80 years) cohorts.
