Study Description

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.

Arms and Interventions

Arm	Intervention/treatment
Experimental: V160 3-Dose Regimen; Participants will receive V160 vaccination by intramuscular (IM) injection on Day 1, Month 2, and Month 6.	Biological: V160; V160 administered as a 0.5 mL (100 Units) IM injection containing Merck aluminum phosphate adjuvant (MAPA)
Experimental: V160 2-Dose Regimen; Participants will receive V160 vaccination by IM injection on Day 1 and Month 6 and placebo at Month 2.	Biological: V160; V160 administered as a 0.5 mL (100 Units) IM injection containing Merck aluminum phosphate adjuvant (MAPA); Drug: Placebo; Saline solution administered as a 0.5 mL IM injection
Placebo Comparator: Placebo; Participants will receive placebo by IM injection on Day 1, Month 3, and Month 6.	Drug: Placebo; Saline solution administered as a 0.5 mL IM injection

Outcome Measures

Primary Outcome Measures :

1. 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.
2. 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.
3. 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.
4. 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.

Secondary Outcome Measures :

1. 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.

• Has a condition in which repeated venipuncture or injections pose more than minimal risk for the participant
• A woman of childbearing potential (WOCBP) who has a positive pregnancy test at screening or within 24 hours before the first dose of study treatment
• Has previously received a CMV vaccine
• Had any live virus vaccine administered or scheduled to be administered in the period from 4 weeks prior to, and 4 weeks following receipt of any dose of trial vaccine
• Had any inactivated vaccine administered or scheduled within the period from 14 days prior to, through 14 days following, any dose of trial vaccine
• Had administration of any immune globulin or blood product within 90 days prior to injection with V160/placebo or scheduled within 30 days thereafter
