Safety Study of Human Anti-Cytomegalovirus Monoclonal Antibody

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01594437
Recruitment Status : Completed
First Posted : May 9, 2012
Last Update Posted : March 21, 2014
Information provided by (Responsible Party):
Theraclone Sciences, Inc.

Brief Summary:
The purpose of this study is to compare the safety profile in healthy adult volunteers of single or multiple intravenous administrations of TCN-202 as compared with placebo.

Condition or disease Intervention/treatment Phase
Cytomegalovirus Infections Biological: TCN-202 Biological: Placebo Phase 1

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.

Arm Intervention/treatment
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

Primary Outcome Measures :
  1. 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 :
  1. Peak serum concentration (Cmax) of TCN-202 [ Time Frame: 1 day post infusion ]
  2. 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.

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