Regulatory News:

LFB today announced that the European Medicines Agency (EMA), the European regulatory authority, has accepted for filing the Marketing Authorization Application for eptacog beta, a recombinant coagulation Factor VIIa (rFVIIa).

The application includes data from three prospective phase 3 clinical trials (PERSEPT 1, PERSEPT 2, and PERSEPT 3) assessing the efficacy and safety of eptacog beta in the treatment of bleeding episodes in children and adults with congenital haemophilia A or B with inhibitors and for the prevention of bleeding in those patients undergoing surgery or invasive procedures. The final outcome from the EMA review is expected by mid-2022.

This announcement comes less than a year after the approval in April 2020 by the United States Food and Drug Administration (FDA) of LFB’s Biologics License Application (BLA) for the coagulation factor VIIa (recombinant)-jncw (eptacog beta), under the name SEVENFACT®, for the treatment and control of bleeding episodes occurring in adults and adolescents (12 years of age and older) with haemophilia A or B with inhibitors. A sBLA efficacy supplement is currently under FDA review, with a regulatory outcome expected by mid-2021. An exclusive license for the commercialization of SEVENFACT^® in the USA has been granted to HEMA Biologics, a joint venture between LFB and US WorldMeds.

In parallel, LFB announces the online publication of the exploratory in vitro study of eptacog beta in combination with emicizumab in the journal Haemophilia. ¹ The combination of eptacog beta with emicizumab results in a concentration-dependent increase in thrombin generation in haemophilia plasma that remains below that of normal non-haemophilic plasma.

These exploratory study results provide in vitro data supporting the concept of eptacog beta use for the treatment of breakthrough bleeding in haemophilia patients treated with emicizumab. A clinical study is planned in the first quarter 2021 to further evaluate the use of SEVENFACT^® in this patient population.² The recommendation from the Medical and Scientific Advisory Council (MASAC) of the National Hemophilia Foundation in the USA supports the use of SEVENFACT^® for the treatment of breakthrough bleeding in patients using emicizumab prophylaxis.³

About the exploratory in vitro study

The aim of this study was to determine the in vitro procoagulant activity of eptacog beta and emicizumab (alone and in combination) utilizing a thrombin generation assay with haemophilia A plasma with and without inhibitors.

A significant increase in peak thrombin, endogenous thrombin potential and velocity was observed for combinations of eptacog beta (0, 1, 2 or 5 µg/mL) with emicizumab (0, 50 or 100 µg/mL) in haemophilia A and haemophilia A plasma with inhibitors; the effect remained below that observed in normal, non-haemophilic plasma.

This study was sponsored by LFB. More details can be found in the study manuscript available at https://onlinelibrary.wiley.com/doi/full/10.1111/hae.14253
