Biotest proceeds into phase III programme in congenital fibrinogen deficiency

- Fibrinogen concentrate shows good efficacy and safety profile based on preliminary data

- Preliminary data on pharmacokinetic profile are comparable to licensed products

- German authority (Paul-Ehrlich-Institut) approved the extension of ongoing study to phase a I/III trial

Dreieich, 1 December 2015. Biotest finalised the phase I part of the ongoing phase I/II study in patients with congenital fibrinogen deficiency in which the distribution of the compound in the human body (pharmacokinetic) was analysed.

In the currently ongoing part II of the study, patients are being treated in case of acute bleeding or as prophylaxis if surgery is planned. So far, preliminary results show a very good therapeutic effect and a favourable safety profile.

The Paul-Ehrlich-Institut recently approved the extension of this study to a phase III trial by keeping the treatment regimen and extending the study to a larger patient population. This study will be the basis for the marketing authorisation application.

The fibrinogen market has continuously been growing in recent years due to a more customised coagulation therapy. This development has been driven by improved and faster bed side diagnostics, enabling physicians to better control bleeding complications.

About fibrinogen and fibrinogen deficiency
Fibrinogen is a clotting factor that is produced in the liver. It plays a key role in primary haemostasis (stopping blood loss from bleeding wounds) and wound healing. In case of a lack or shortage of fibrinogen blood's ability to clot is impaired which leads to a much greater risk of bleeding and delayed haemostasis. So far, these patients have been treated primarily with fresh frozen plasma (FFP). The administration of Fibrinogen is based on the point-of-cared diagnostic data which allows a tailor-made, patient specific and highly effective therapy.

Biotest's fibrinogen concentrate
The recently developed manufacturing process of fibrinogen concentrate is leading to a high-purity fibrinogen with a high level of viral safety and good solubility.

About the study
The study was designed as a prospective, open-label, multicentre, phase I/III study investigating the 14 day single-dose pharmacokinetic properties, efficacy and safety of fibrinogen (BT-524) following intravenous administration in the treatment or prophylaxis of bleeding in patients with congenital fibrinogen deficiency ( Identifier NCT02065882).
