The aim of this trial is to verify, under controlled conditions, the reported efficacy of human cytomegalovirus (HCMV)-specific hyperimmune globulin administration to pregnant women suffering from primary HCMV infection for the prevention of intrauterine HCMV transmission.

Condition Intervention Phase
Cytomegalovirus Infection
Drug: HCMV-specific hyperimmune globulin (Cytotect®)
Drug: Isotonic solution of sodium chloride (placebo)
Phase 2
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Prevention of Human Cytomegalovirus (HCMV) Mother-to-fetus Transmission by Administration of Virus-specific Hyperimmune Globulin to Pregnant Women With Primary HCMV Infection

Primary Outcome Measures:
  • Evidence of congenital HCMV infection in the fetus/newborn [ Time Frame: At amniocentesis and/or within one week after birth ]

Secondary Outcome Measures:
  • HCMV-specific immune response (humoral and cell-mediated) [ Time Frame: 36-48 months ]
  • Virological and histological findings in placentas [ Time Frame: 36-48 months ]
  • Clinical outcome of newborns with congenital HCMV infection [ Time Frame: within 2 weeks after birth ]
  • Safety of Cytotect in the mother and newborn [ Time Frame: within 24 hours after delivery ]

Enrollment: 124
Study Start Date: June 2009
Study Completion Date: October 2011
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cytotect Drug: HCMV-specific hyperimmune globulin (Cytotect®)
100U (2.0ml)/Kg i.v. every 4 weeks up to 38 weeks' gestation or HCMV-positive amniocentesis or pregnancy termination.
Other Name: Cytotect®
Placebo Comparator: placebo Drug: Isotonic solution of sodium chloride (placebo)
2.0ml/Kg i.v. every 4 weeks until 38 weeks'gestation or HCMV-positive amniocentesis or pregnancy termination

Detailed Description:

HCMV is the leading infectious cause of mental retardation and deafness in infants with congenital HCMV infection. Primary HCMV infections during pregnancy carry the highest risk of fetal infection and disease. No intervention of proven efficacy is available in case of primary HCMV infection in pregnancy. However, a study published in 2005 (Nigro et al., NEJM 353:1350-62, 2005) reported that in pregnant women with primary HCMV infection treated with HCMV-specific hyperimmune globulin (Cytotect®, Biotest) the risk of transmitting the infection to the fetus was reduced from 40% to 16%. Unfortunately, since the study was conducted with inadequate controls, the actual efficacy of hyperimmune globulin could not be properly assessed.

In the present randomized, double-blind, placebo-controlled, multicenter trial pregnant women with ascertained primary HCMV infection at 4-26 weeks of gestation will be randomized to receive Cytotect® or placebo intravenously within 6 weeks after the presumed onset of infection.

Primary efficacy parameter will be the number of HCMV-infected newborns or fetuses.
