Safety of a Single Intravenous Dose of Recombinant Factor XIII in Children With Congenital FXIII A-subunit Deficiency (mentor™4)

January 10, 2017 updated by: Novo Nordisk A/S

A Phase 3b Trial Investigating the Pharmacokinetics and Safety Profile of a Single Intravenous Dose of rFXIII in Paediatric (1 to Less Than 6 Years Old) Subjects With Congenital FXIII A-subunit Deficiency

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 6 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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
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.
At pre-dose, 30 minutes, 24 hours, 7, 14, 21 and 30 days after dosing

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Area Under the Concentration vs. Time Curve (AUC0-∞)
Time Frame: From day 0 to day 30
A measure of exposure.
From day 0 to day 30
Maximum Plasma Concentration (Cmax) for FXIII
Time Frame: At pre-dose, 30 minutes, 24 hours, 7, 14, 21 and 30 days after dosing
Maximum plasma concentration of the drug reached.
At pre-dose, 30 minutes, 24 hours, 7, 14, 21 and 30 days after dosing
Terminal Half-life (t½)
Time Frame: From day 0 to day 30
Time point when half of the maximum plasma concentration is reached.
From day 0 to day 30
Mean Residence Time (MRT)
Time Frame: From day 0 to day 30
The mean residence time (MRT) of a drug in the body and related functions are derived for drugs which are intravenously administered.
From day 0 to day 30
Total Plasma Clearance (CL)
Time Frame: From day 0 to day 30
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').
From day 0 to day 30
Volume of Distribution at Steady State (Vss)
Time Frame: At steady state
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.
At steady state
Percentage of Subjects With One or More Adverse Events (AEs) Recorded
Time Frame: From day 0 to day 30
From day 0 to day 30
Percentage of Subjects With One or More Serious Adverse Events (SAEs)
Time Frame: From day 0 to day 30
From day 0 to day 30
Percentage of Subjects With Development of Anti-rFXIII Antibodies, Including Inhibitors (Neutralising Antibodies Against Factor XIII)
Time Frame: At screening and day 30
At screening and day 30
Coagulation Related Parameters - Fibrinogen
Time Frame: Day 0 and at day 30
Day 0 and at day 30
Coagulation Related Parameters - Activated Partial Thromboplastin Time (aPTT, Seconds)
Time Frame: Day 0 and day 30
Day 0 and day 30
Coagulation Related Parameters - Prothrombin Time (PT) (Seconds)
Time Frame: Day 0 and day 30
Day 0 and day 30
Clot Solubility Test (Evaluated as Normal/Abnormal)
Time Frame: Day 0 and day 30
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).
Day 0 and day 30
Vital Signs - Pulse
Time Frame: Day 0 and day 30
Day 0 and day 30
Vital Signs - Blood Pressure (Systolic and Diastolic)
Time Frame: Day 0 and day 30

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
