Prediction of the Efficacy of Activated Recombinant Human Factor VII in Adult Congenital Haemophilia A or B Patients With Inhibitors by Use of Thromboelastography

A Phase 1 interventional study of eptacog alfa (activated) in Congenital Bleeding Disorder, Haemophilia A With Inhibitors and Haemophilia B With Inhibitors, sponsored by Novo Nordisk A/S. Completed at 7 sites in 4 countries. Open to male participants aged 16 Years and older. Per ClinicalTrials.gov, last updated 2016-11-23.

Study summary

This trial is conducted in Europe and the United States of America (USA). The aim of this trial is to evaluate the basal and spiked TEG® (Thromboelastography) or ROTEM® (Thromboelastometry) profiles of frequently bleeding haemophilia subjects with inhibitors in a non-bleeding state.

Read the detailed description

The TEG parameters are: R time (Reaction Time), K time (K Time (arbitrary measurement)), a (a angle), MA (Maximum Amplitude) and LY30 (Lysis 30 min after MA) while the ROTEM parameters are: CT (Clotting Time), CFT (Clot Formation Time), a (a angle), MCF (Maximum Clot Firmness) and LI60 (Lysis index 60 min after CT)

Inclusion criteria

  • Confirmed diagnosis of congenital haemophilia A or B with a FVIII:C clot activity or FIX:C clot activity, respectively, less than 5%

  • A documented historical or present record for the presence of inhibitors to factor VIII or IX, respectively
  • A documented history of 2 or more joint bleeding episodes during the preceding 12 months
  • Subjects must be in a non-bleeding state (i.e. no clinical manifestations of active bleeds)

Exclusion criteria

Exclusion Criteria:

  • Subjects who have received any haemostatic treatment for a bleeding episode within the last 7 days prior to this trial
  • Immune tolerance therapy within the last 30 days prior to this trial
  • Clinically relevant coagulation disorders other than congenital haemophilia A or B
  • Thrombocytopenia (platelet count below 60,000 platelets/mcl)

Interventions

  • Drugeptacog alfa (activated)

    Subjects will be called to attend the clinic in a non-bleeding state. Blood samples will be drawn for thromboelastogram profiling and will be in-vitro spiked with different doses of activatated recombinant human factor VII.
