Study Comparing the Pharmacokinetic of Biosimilar Eptacog Alfa With Novoseven®, in Patients With Congenital Factor VII Deficiency
Iran24 participantsStarted 2017-03-01
Plain-language summary
The purpose of this multicentre, randomized, double blinded, single dose, two-way cross-over study, is to compare the pharmacokinetics (PK) of biosimilar eptacog alfa (activated) with Novoseven in 24 patients, adult and children (\>12 years), not bleeding, with inherited coagulation factor VII (FVII) deficiency (FVII \<1%). Patients will be randomized to receive either a single dose of eptacog alfa biosimilar 30 μg/kg and one single dose of NovoSeven 30 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients with a confirmed diagnosis of congenital, severe Factor VII deficiency (FVII \<1%), with \> 2 episodes of bleeding/year requiring treatment with FVII infusions, in non bleeding status.
* Patients for the Additional group for immunogenicity should be enrolled when in a bleeding episode requiring treatment with FVII.
* Male and female subjects
* Adult and children (\>12 years)
* Written informed consent. For minor patients, parent/legal guardian will provide consent and, when possible, patient assent will also be obtained. For compromised patients their designated proxy must provide informed consent.
Exclusion Criteria:
* Any other type of congenital or acquired coagulopathy (except congenital Factor VII deficiency), such as: liver disease (hepatitis), vitamin k deficiency, uremia, malignancy.
* Antibodies against Factor VII
* Patients entering the PK Study Group who have not suspended prophylactic regimen with Novoseven or AryoSeven (biosimilar eptacog alfa) 3 days before starting the trial (receiving first dose of study medication).
* Patients entering the Additional Group for Immunogenicity study, only, who have been exposed to AryoSeven before starting study \[patients who have received Novoseven (on demand or in prophylaxis) before starting study are allowed\]
* Platelet count less than 100.000 platelets/μl (at screening visit)
* Patients who have received routine (prophylactic) treatment with rFVIIa in the period between screening visit (…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

1
Area under the plasma activity-time curve from time 0 to last quantifiable activity (AUClast)
Timeframe: Ten min before injection and 10 min, 20 min, 1h, 3h, 6h, 8h, 12h, 24h and 30h after injection, for both drug administered in the PK phase
2
Maximum plasma concentration of the factor VII activity (Cmax).
Timeframe: Ten min before injection and 10 min, 20 min, 1h, 3h, 6h, 8h, 12h, 24h and 30h after injection, for both drug administered in the PK phase
