Clinical Trial Comparing a Biosimilar Eptacog Alfa With Novoseven, in Patients With Hemophilia With Inhibitors

A Randomized, Multicenter, Double-blind Clinical Trial Comparing Pharmacodynamic, Pharmacokinetic and Safety of a Biosimilar Eptacog Alfa (AryoSeven) and Novoseven®, in Patients With Hemophilia A or B With Inhibitors.

• Status: Completed
• Phase: Phase 3

Summary

The purpose of this multicentre, randomized, double-blinded, single dose, two-way cross-over study, is to compare the pharmacokinetics (PK) and pharmacodynamic (PD) of two different doses of the biosimilar eptacog alfa (activated) with Novoseven in 48 patients, adult and children (\>12 years), not bleeding, with hemophilia A or B with inhibitors. Patients will be randomized to receive either a single dose of eptacog alfa biosimilar 90 μg/kg or 270 μg/kg and one single dose of NovoSeven 90 μg/kg or 270 μg/kg, or vice versa, with doses separated by a washout period. All patients will be followed 12 months and will receive biosimilar eptacog alfa, on demand, for every bleeding episode that should occur - or - for prophylaxis, with the aim of monitoring of inhibiting antibody formation, lack of efficacy and collection of safety data.

Detailed description

Forty-eight patients enrolled, not bleeding, will be randomized to receive two injections separated by a washout period of 3 days (t1/2 = 2.3h). Patients are centrally registered and randomized to receive in a 2x2 cross-over setting either a single dose of two for the following products: A: AryoSeven 90 µg/kg and B: NovoSeven 90 µg/kg - or - C: AryoSeven 270 µg/kg and D: NovoSeven 270 µg/kg. Patients will be hospitalized at the time of study medication administration and plasma sampling. Before any treatment, a blood sample will be obtained in all patients for testing for immunogenicity.

Type	Name	Description
BIOLOGICAL	Biosimilar eptacog alfa, activated (AryoSeven)	A single dose of eptacog alfa biosimilar (AryoSeven) 90 μg/kg or 270 μg/kg. Then, in an open follow up phase of 12 months, for every bleeding episode patients will receive eptacog alfa biosimilar, on demand, for one of more days until resolution of bleeding, based on the Investigator's decision - or - prophylaxis with eptacog alfa biosimilar, with dose, frequency, and duration of treatment based on the Investigator's decision. The modality of treatment (on demand or prophylaxis) will be decided by the Investigator.
