Elucidation of the biochemical properties of efanesoctocog alpha in the coagulation reaction (ISTH 2025) - "Aims In the present study, we examined the cause of the difference between the two methods by comparing Efa to rurioctocog alfa (Ruri). In the ELISA, the antigen level of Efa was 1.32-fold higher than that of Ruri. The level of Efa 100U/mL measured by spectrophotometer was 2.5-fold higher than that of Ruri, although this might be due to the difference in molecular weight."

Impact of Extended Half-Life Factor VIII on Pharmacokinetics and Bleeding Rates in Hemophilia A (ISTH 2025) - "Patients initially treated with SHL FVIII (Beriate®, Immunate®, Octanate®, Advate®, Novoeight®, Hemophil M®, Xyntha®) and later switched to EHL FVIII (Adynovate®, Jivi®) were included. A weak, non-significant negative correlation existed between spontaneous bleeding and T1/2 for both SHL (r=-0.23, IC 95% -0.51 to 0.09, p>0.05) and EHL (r=-0.24, IC 95% -0.49 to 0.05, p>0.05). A significant positive correlation was observed between AUC and T1/2 (r=0.79, IC 95% 0.7 to 0.86, p<0.05) Table or Figure Upload"

Role of factor VIII as a regulator of angiogenesis and promoter of endothelial barrier stability (ISTH 2025) - "HA BOECs were treated in vitro with simoctocog alfa, efmoroctocog alfa, rurioctocog alfa pegol, damoctocog alfa pegol, octocog alfa, efanesoctocog alfa or non-factor therapy, emicizumab. Furthermore, simoctocog alfa in vivo rescue was greater compared to efmoroctocog alfa or efanesoctocog alfa. These effects on ECs may be mediated by the binding and signaling of simoctocog alfa to the ECs surface."

Indirect Comparison of the Efficacy and Therapy-Related Costs of a Pharmacokinetic and Individualized Prophylaxis Regimen with Simoctocog Alfa Versus Other Extended-Half Life Factor VIII Concentrates (ASH 2024) - "For comparison, aggregated data was obtained from the following trials with EHL concentrates : pathfinder2 (turoctocog alfa pegol, N = 175), A-LONG (efmoroctocog alfa, N = 117), PROTECT FVIII (damoctocog alfa pegol, N = 110), PROPEL (rurioctocog alfa pegol 1–3% and 8–12%; N = 57 and 58), and XTEND-1 (efanesoctocog alfa, Group A, N = 133). Conclusion : Albeit at a generally higher weekly dose, a PK-guided, individualized prophylaxis regimen with simoctocog alfa offered comparable or significantly improved zero bleed rates and significantly lower or comparable ABRs than prophylactic regimens with EHL rFVIII concentrates. Nevertheless, the estimated annual cost of a simoctocog alfa-based regimen is 20–55% lower than with the other concentrates."

Role of Factor VIII As a Regulator of Angiogenesis and Promoter of Endothelial Barrier Stability (ASH 2024) - "HA BOECs were treated in vitro with the rFVIII products simoctocog alfa (Nuwiq®), efmoroctocog alfa (Elocta®), rurioctocog alfa pegol (Adynovate®), damoctocog alfa pegol (Jivi®), octocog alfa (Advate®), or emicizumab (Hemlibra®). Investigating the potential extra-coagulative role of FVIII could be crucial to understanding the key molecular targets at the cellular level which impair EC function in patients with HA. Knowledge of the possible effect of different rFVIII products and non-factor therapies on EC function can be used to optimize therapeutic approaches, which in turn may result in safer and more efficient treatment of HA."

Cost Comparison of Efanesoctocog Alfa with Existing Factor VIII Replacement Therapies for Major Surgeries in People with Severe Hemophilia a (ASH 2024) - P2/3, P3 | "Objective To estimate total costs associated with perioperative hemostatic management in patients with severe HA treated with SHL (octocog alfa), EHL (rurioctocog alfa pegol and efmoroctocog alfa), and high-sustained (efanesoctocog alfa) FVIII replacement therapies. This is attributed to its high-sustained factor activity and reduced factor consumption during the reported perioperative period. The major limitations of the study were : the types of major surgeries varied among studies; the perioperative period data of octocog alfa were not found."

Impact of Variable Recombinant Factor VIII Binding on Platelet Functions (ASH 2024) - "rFVIII-platelet binding : Activated platelets were incubated with simoctocog alfa (Nuwiq®), efmoroctocog alfa (Elocta®), rurioctocog alfa pegol (Adynovate®) or damoctocog alfa pegol (Jivi®). The rFVIII products explored in this study bound to platelets with varying strength, with simoctocog alfa demonstrating the highest amount of platelet binding, as well as the highest interaction with pro-aggregatory platelets. These findings indicate that variations in platelet binding may influence the efficacy of rFVIII products in the treatment of HA."
