NCT06564194
Brief Summary:
The goal of this clinical trial is to assess the safety, reactogenicity and immunogenicity of an mRNA-based vaccine, JCXH-108, the prevention of Respiratory Syncytial Virus (RSV) infection and diseases.
Participants will be randomized to receive either JCXH-108 or placebo.
Detailed Description:
This Phase 1 study plans to enroll a total of 75 participants.
Three cohorts with two different dose levels will be explored and each cohort will enroll 25 participants. Participants in each cohort will be randomized (4:1) to receive either JCXH-108 (n=20) or placebo (normal saline, n=5). A low dose of JCXH-108 will be explored vs placebo in the 18-45 years of age group first. A high dose will be explored vs placebo in the 18-45 years and ≥ 60 years of age groups once safety data is reviewed for the Sentinel subjects in the low dose cohort. The dose level of JCXH-108 will depend on the time the participant joins the study. Each participant will receive a single dose of JCXH-108 administered intramuscularly (IM) on day 1.
