This trial is conducted in Europe and United States of America (USA). The aim of this clinical trial is to investigate the pharmacokinetics (at which rate the substance is distributed and eliminated from the body) and the safety profile of catridecacog (recombinant factor XIII (rFXIII)) in children with congenital FXIII A-subunit deficiency. Young children (1 to less than 6 years old) with congenital FXIII deficiency are evaluated.

Primary Outcome Measures:
  • Area Under the Concentration vs. Time Curve (AUC) [ Time Frame: At pre-dose, 30 minutes, 24 hours, 7, 14, 21 and 30 days after dosing ] [ Designated as safety issue: No ]
    A measure of the exposure. Blood samples for the PK assessment were drawn pre-dose and up to 30 days after dosing. The PK of FXIII in children was assessed after a single i.v. dose of rFXIII 35 IU/kg.

Secondary Outcome Measures:
  • Area Under the Concentration vs. Time Curve (AUC0-∞) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
    A measure of exposure.

  • Maximum Plasma Concentration (Cmax) for FXIII [ Time Frame: At pre-dose, 30 minutes, 24 hours, 7, 14, 21 and 30 days after dosing ] [ Designated as safety issue: No ]
    Maximum plasma concentration of the drug reached.

  • Terminal Half-life (t½) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
    Time point when half of the maximum plasma concentration is reached.

  • Mean Residence Time (MRT) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
    The mean residence time (MRT) of a drug in the body and related functions are derived for drugs which are intravenously administered.

  • Total Plasma Clearance (CL) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
    The total plasma clearance is a measure of the elimination of a drug from the body. Drugs are excreted primarily by the kidneys into the urine. Clearance is calculated as 'CL=Dose / AUC0-30 days').

  • Volume of Distribution at Steady State (Vss) [ Time Frame: At steady state ] [ Designated as safety issue: No ]
    Volume of distribution at steady state (Vss) is the theoretical volume that the total amount of administered drug would have to occupy (if it were uniformly distributed), to provide the same concentration as it is in blood plasma at steady state. Steady state is achieved when all variables are constant in spite of ongoing processes.

  • Percentage of Subjects With One or More Adverse Events (AEs) Recorded [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
  • Percentage of Subjects With One or More Serious Adverse Events (SAEs) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
  • Percentage of Subjects With Development of Anti-rFXIII Antibodies, Including Inhibitors (Neutralising Antibodies Against Factor XIII) [ Time Frame: At screening and day 30 ] [ Designated as safety issue: No ]
  • Coagulation Related Parameters - Fibrinogen [ Time Frame: Day 0 and at day 30 ] [ Designated as safety issue: No ]
  • Coagulation Related Parameters - Activated Partial Thromboplastin Time (aPTT, Seconds) [ Time Frame: Day 0 and day 30 ] [ Designated as safety issue: No ]
  • Coagulation Related Parameters - Prothrombin Time (PT) (Seconds) [ Time Frame: Day 0 and day 30 ] [ Designated as safety issue: No ]
  • Clot Solubility Test (Evaluated as Normal/Abnormal) [ Time Frame: Day 0 and day 30 ] [ Designated as safety issue: No ]
    Blood samples for clot solubility drawn at each visit (1 hour before and after dose administration). A clot solubility assay was used to screen for FXIII deficiency. The assay is based on the ability of urea to dissolve fibrin clots that have not undergone FXIII-induced stabilization. Normal blood clots generally remain stable for 24 hours or more, while clots in which fibrin molecules have not been cross-linked are soluble within minutes. The outcome of the test is normal (FXIII present; a clot is observed in the test tube) or abnormal (FXIII absent or very low level; no clot in test tube).

  • Vital Signs - Pulse [ Time Frame: Day 0 and day 30 ] [ Designated as safety issue: No ]
  • Vital Signs - Blood Pressure (Systolic and Diastolic) [ Time Frame: Day 0 and day 30 ] [ Designated as safety issue: No ]
  • Physical Examination (Evaluated as Normal/Abnormal) [ Time Frame: From day 0 to day 30 ] [ Designated as safety issue: No ]
