Mechanism: Extended half-life recombinant Factor VIII
Expert: Recombinant FVIII-Fc fusion protein with XTEN polypeptide technology (efanesoctocog alfa). Single-chain design with enhanced VWF interaction provides 3-4x extended half-life compared to standard rFVIII. Achieves sustained near-normal FVIII activity levels with once-weekly IV dosing.
Everyday: A longer-lasting version of the missing clotting factor itself. Normal Factor VIII replacement needs injection every 2-3 days because it gets cleared from blood quickly. This version is engineered to last longer (Fc fusion + XTEN technology), so patients only need a weekly infusion instead.

Notes
Extended half-life rFVIII. 3-4x longer half-life via Fc fusion + XTEN tech. Weekly IV achieves near-normal FVIII levels. $702M in 2024 (rapid ramp). For patients preferring actual factor replacement. Key differentiator: normalizes FVIII levels (relevant for surgery, trauma) vs nonfactor therapies. DUAL BRANDING: Marketed as Altuviiio by Sanofi (US) and Altuvoct by SOBI (ex-US). Same drug (efanesoctocog alfa). SOBI ex-US revenue: SEK 1,023M in Q4 2025 (vs SEK 302M prior year Q4) — rapid launch ramp.
