A Phase 2 Parallel-Group, Randomized, Double-Blind Study to Assess the Safety and Immunogenicity of PXVX0317 (Chikungunya Virus Virus-Like Particle Vaccine [CHIKV-VLP], Unadjuvanted or Alum-adjuvanted)
The goal of this Phase 2 trial is to evaluate the immune response to and safety profile of
various doses/formulations/and schedules of administration of PXVX0317 in healthy adults.
Primary Objective:
To assess the immune response to the vaccine
Secondary Objectives:
To assess the kinetics of the immune response to different doses/formulations/schedules To
assess the persistence of immune responses to different doses/formulations/schedules To
assess the effect of a booster dose of the vaccine
Safety Objective:
To assess local and systemic reactions to the vaccine and to describe the safety profile of
the vaccine

Safety Objective:
To assess local and systemic reactions to the vaccine and to describe the safety profile of
the vaccine
The trial will explore 8 formulation/schedule combinations of CHIKV VLP vaccine with or
without Alhydrogel adjuvant, and will also explore different dose schedules of Day 1 and 15
or Day 1 and 29 or Day 29 only.
without Alhydrogel adjuvant, and will also explore different dose schedules of Day 1 and 15
or Day 1 and 29 or Day 29 only.

11. Any other condition that, in the opinion of the Investigator, creates an unacceptable
risk to the subject.
12. Any other condition that, in the opinion of the Investigator, may interfere with the
conduct of the study or the validity of the data.
