Official title

A Phase 1, Dose Escalation, Placebo-Controlled, Adaptive-Design Study to Evaluate the Safety and Immunogenicity of VXCO-102, a mRNA Vaccine Targeting Epstein-Barr Virus (EBV) in Healthy Young Adults

Overview

This is an adaptive design Phase 1 clinical trial to evaluate the safety and immunogenicity of VXCO-102 in healthy adult participants.

Detailed description

This first-in-human, dose-escalation Phase 1 trial evaluates the safety, tolerability, and immunogenicity of VXCO-102 in healthy young adults across multiple sites in Australia.

Part A will enroll \~45 participants aged 18-25. After sentinel safety review in each dose cohort, participants will be randomized to receive VXCO-102 or placebo, with a booster at Week 8. If Part A results are favorable, the study may expand to Part B to further assess safety, reactogenicity, and immunogenicity.

All participants will undergo ongoing safety monitoring and immune response assessments through clinical evaluations, sample collection, and participant reporting.
