Evaluation of Recombinant Factor XIII for Prevention of Bleeding in Patients With FXIII Inherited Deficiency

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

A Multi-Centre, Open-Label, Single-Arm and Multiple Dosing Trial on Efficacy and Safety of Monthly Replacement Therapy With Recombinant Factor XIII (rFXIII) in Subjects With Congenital Factor XIII Deficiency

The trial is conducted in Europe, North America and Asia. The aim of this trial is to evaluate catridecacog (recombinant factor XIII (rFXIII)) treatment in patients with inherited FXIII deficiency. It is expected that recombinant FXIII can be used for the prevention of bleeding episodes.

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.

Inclusion Criteria:

  • Diagnosis of congenital FXIII A-subunit deficiency (confirmed by genotyping at screening visit)
  • Treatment with regular FXIII replacement therapy initiated at least 6 months prior to screening and one of the following : a documented history of at least one 1 treatment-requiring bleeding episode prior to initiation of regular replacement therapy or a documented family history of FXIII congenital deficiency (only for subjects on regular replacement therapy prior to screening)
  • Documented history of at least two 2 bleeding episodes requiring treatment with FXIII containing blood products within the last 12 months prior to screening (only for subjects receiving on-demand treatment prior to screening)

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate (Number Per Subject Year) of Bleeding Episodes Requiring Treatment With a FXIII Containing Product During the Treatment Period
Time Frame: For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
It represents the incidence of bleeding episodes requiring treatment with a FXIII-containing product.
For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Subjects Having a Normal Clot Solubility One Hour After rFXIII Administration and 28 Days After rFXIII Administration for All Dosing Visits
Time Frame: For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
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).
For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
Level of FXIII Activity One Hour After rFXIII Administration and 28 Days After rFXIII Administration for All Dosing Visits
Time Frame: For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
Subjects entered a 52-week treatment period of monthly (28±2 days) doses of 35 IU/kg rFXIII. Blood samples for analysis of FXIII activity were drawn at each visit; at dosing visits blood was drawn 1 hour after administration and before administration(corresponding to 28 days after the previous dose). All Dosing Visits are visits where a dose is given (i.e. Visit 2-15 except Visit 3).
For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
Number of Subjects With rFXIII Antibody Development
Time Frame: For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
Subjects receiving rFXIII were monitored for the development of binding antibodies. Blood sampling was done before administration of trial product at all visits (Visits 1-16 and unscheduled visit)
For a period of 322 days (approximately one year) comprised of a screening visit (Visit 1), treatment period (Visits 2-15), unscheduled visit and end-of-trial visit (Visit 16).
