Official title

Double-Blind, Randomized, Placebo-Controlled Phase 2b, Multi-center Study to Evaluate the Safety, Tolerability, Efficacy and Immunogenicity of a 2-Dose and a 3-Dose Regimen of V160 (Cytomegalovirus [CMV] Vaccine) in Healthy Seronegative Women, 16 to 35 Years of Age

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study evaluated the safety, tolerability, and efficacy of the cytomegalovirus (CMV) vaccine (V160) administered in a 2-dose or 3-dose regimen to healthy seronegative women 16 to 35 years of age. Participants received blinded V160 on Day 1, Month 2, and Month 6 (3-dose regimen), V160 on Day 1 and Month 6 and placebo at Month 2 (2-dose regimen), or placebo on Day 1, Month 2, and Month 6, and were followed to approximately Month 24. The primary hypothesis of the study was that administration of a 3-dose regimen of V160 will reduce the incidence of primary CMV infection compared to placebo.
