Primary Outcome Measures:
  • Number and severity of adverse events [ Time Frame: 60 days post infusion ]
    Adverse events will be determined by physical examinations, vital signs, serial electrocardiograms, and clinical laboratory abnormalities (hematology, chemistry, and urinalysis).

Secondary Outcome Measures:
  • Peak serum concentration (Cmax) of TCN-202 [ Time Frame: 1 day post infusion ]
  • Number of subjects who develop anti-TCN-202 anti-drug antibodies (immunogenicity) [ Time Frame: 60 days post infusion ]
    Immunogenicity will be assessed based on induction of TCN-202 anti-drug antibodies.

  • Area under the concentration time curve (AUC) of TCN-202 [ Time Frame: 60 days post infusion ]
  • Time to maximum serum concentration (Tmax) of TCN-202 [ Time Frame: 1 day post infusion ]

Enrollment: 48
Study Start Date: May 2012
Study Completion Date: March 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TCN-202 Biological: TCN-202
Human monoclonal neutralizing antibody that recognizes a broadly conserved functional epitope on HCMV. One or two doses will be administered by intravenous infusion.
Other Name: Human Anti-Cytomegalovirus Monoclonal Antibody
Placebo Comparator: Placebo Biological: Placebo
One or two doses administered by intravenous infusion.
Other Name: 0.9% Sodium chloride for Injection, USP

Detailed Description:
Human cytomegalovirus (HCMV) disease remains an unmet medical need: In the US, the estimated prevalence of congenital HCMV infection is ~1% and is one of the leading causes of permanent hearing loss and neurological deficits in children. In immunocompromised individuals such as transplant recipients it can cause serious life-threatening disease and may significantly increase the risk of graft rejection. As existing therapies for HCMV can have serious side effects, there remains a medical need for safe and effective treatment of HCMV disease.
