Platelets stabilize factor VIIIa against loss of activity through subunit dissociation
(ASH 2025)
- "We wished to determine whether FVIII activity on platelet binding sites is enhanced bystabilization against A2 dissociation and/or protease cleavage.Like FVIII, the bispecific antibody emicizumab (Emi) serves as a cofactor that facilitates activation of FX byFIXa on either vesicles or platelets...Full-length recombinant factorVIII (octocog alfa (Antihemophilic Factor), Advate) was also used as a control (FVIII).Plasma clotting assays were performed using delipidated factor VIII-deficient plasma with corn trypsininhibitor to inhibit contact pathway activation...We are currently investigating the effect of the reported slower IIacleavage of full-length FVIII at residue 1689 as a possible explanation. Further experiments will probe therole(s) of FIXa and FX on decay of B domain deleted FVIII activity on platelets vs PLV.Our data shows that platelet binding sites provide enhanced factor VIII activity compared to phospholipidvesicles and suggests that stabilization of FVIIIa..."

A FXIa-modified clot waveform analysis for estimation of factor VIII level and emicizumab concentration in hemophilia A
(ASH 2025)
- "MethodsWe used plasma samples (N=42) from patients with severe hemophilia A (endogenous FVIII level <1IU/dL,without inhibitor) on treatment with emicizumab and spiked FVIII (standard half-life, octocog alfa) toachieve target levels (50-100 IU/dL). FXIa+TF-CWA and diluted aPTT+TF-CWA were better atdiscriminating additional FVIII in emicizumab samples than undiluted aPTT-CWA. These findings indicatethat FXIa+TF-CWA and diluted aPTT+TF-CWA better discriminate clotting dynamics of emicizumab andadditional FVIII substitution, which may be of use in clinical scenarios like peri-interventional monitoring."

Patient characteristics, treatment patterns, and bleeding in people with Hemophilia A without inhibitors initiating efanesoctocog alfa in the US: An administrative claims analysis
(ASH 2025)
- "The mean (SD) Charlson Comorbidity Index score among all patients was 0.49 (1.28).Within the 180-day pre-index period, 81.3% of patients received any prophylaxis (FVIII or emicizumab),5% used on-demand FVIII therapy only, and 13.7% patients were not treated with FVIII or emicizumab.The most commonly used products as on-demand or prophylactic prior to index were efmoroctocog alfa(30.0%), octocog alfa (17.5%), emicizumab (15.0%), and rurioctocog alfa pegol (11.3%). This retrospective claims analysis showed that bleed rates among PwHA receiving Efa werelow, consistent with outcomes observed in clinical trials. Most patients transitioning to Efa werepreviously treated with EHLs. Majority of patients continued treatment during the follow-up period, withrelatively low switching or discontinuation of treatment."

Results Preoperative FVIII administration achieved a peak level of 121.4%.Postoperative monitoring showed a progressive decline in FVIII levels:72%..."

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."

Extended MAIC to Validate Results in Cases of Poor Population Overlap: An Application to Compare Prophylactic Treatments in Pediatric Patients With Hemophilia A
(ISPOR 2025)
- " Patient-level data from a single-arm trial evaluating a novel antihemophilic therapy (Int_A) were compared with aggregated data from the LEOPOLD Kids trial assessing octocog alfa (OctA)... The proposed method quantifies the risk of bias in MAIC when populations poorly overlap. By addressing imbalances and testing plausible scenarios, this approach enhances the robustness and credibility of MAIC results, reducing the risk of misleading conclusions."

Role of Factor VIII As a Regulator of Angiogenesis and Promoter of Endothelial Barrier Stability

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

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."
