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
In Brief
A Phase 2 clinical trial evaluating V160 and Placebo for Cytomegalovirus (CMV) Infections. Completed, enrolled 2,200 participants across 95 sites in 7 countries.
Detailed Summary
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.
