Current Primary Outcome Measures (submitted: March 28, 2018)

• Incidence of Cytomegalovirus Infection in the 3-dose Regimen Group [ Time Frame: Up to Month 36 ]
  CMV infection is defined as detection of CMV (non-vaccine type) by polymerase chain reaction in a single saliva or urine sample in a previously CMV-uninfected participant. The incidence of CMV infection in participants receiving the 3-dose V160 regimen will be assessed.
• Solicited Injection-site AEs [ Time Frame: Up to 5 days after each vaccination ]
  The percentage of participants with one or more solicited injection-site AE (pain/tenderness, erythema/redness, swelling) will be assessed.
• Solicited Systemic AEs [ Time Frame: Up to 14 days after each vaccination ]
  The percentage of participants with one or more solicited systemic AEs (headache, fatigue, muscle pain, joint pain) will be assessed.
• Vaccine-related Serious Adverse Events (SAEs) [ Time Frame: Up to 14 days after each vaccination ]
  The percentage of participants with a vaccine-related SAE will be assessed.

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: March 28, 2018)

Incidence of Cytomegalovirus Infection in the 2-dose Regimen Group [ Time Frame: Up to Month 36 ]

CMV infection is defined as detection of CMV (non-vaccine type) by polymerase chain reaction in a single saliva or urine sample in a previously CMV-uninfected participant. The incidence of CMV infection in participants receiving the 2-dose V160 regimen will be assessed.

Descriptive Information

• Brief Title: Safety, Tolerability, and Efficacy of the Human Cytomegalovirus Vaccine (V160) in Healthy Women 16 to 35 Years of Age (V160-002)
• 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: This study will evaluate the safety, tolerability, and efficacy of Human Cytomegalovirus (CMV) vaccine V160 administered in a 2-dose or 3-dose regimen in healthy seronegative women 16 to 35 years of age. Participants will receive 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 will be followed to approximately Month 36. The primary hypothesis of the study is that administration of a 3-dose regimen of V160 will reduce the incidence of primary CMV infection compared to placebo.
