Safety, Tolerability, and Immunogenicity of the Human Cytomegalovirus Vaccine (V160) in Healthy Adults (V160-001)

Summary

This study will evaluate the safety, tolerability, and immunogenicity of various doses, formulations, and routes of administration of Human Cytomegalovirus (HCMV) vaccine V160 administered in a 3-dose regimen in healthy adults. The initial treatment arm of HCMV seropositive participants will receive V160 Low Dose without adjuvant by intramuscular injection. Escalation of the V160 dose, inclusion of adjuvant, administration by intradermal injection, and vaccination of HCMV seronegative participants will be performed only after review of safety data of previous treatment arms. The purpose of the study is to identify vaccine formulations associated with optimal safety profile and HCMV-specific immune response for evaluation in subsequent clinical studies of V160.
