Molecular Design Implications

Unlike most of the currently available rFVIII products that are manufactured using a hamster cell line (Chinese Hamster Ovary or Baby Hamster Kidney cells), NUWIQ is produced in a human cell line.1,2

In fact, NUWIQ is the first and only rFVIII produced in a human cell line without chemical modification or protein fusion.1,2

NUWIQ – Produced in a Human Cell Line

  • Human cell lines express only human post-translational modifications, like glycosylation and sulfation, to produce a rFVIII protein that closely resembles the FVIII the body produces naturally 3
  • Protein expression in hamster cell lines results in glycosylation with non-human epitopes, which are potentially antigenic to humans3
  • NUWIQ contains only human glycan epitopes

NUWIQ – Minimizing Unbound FVIII1,3

  • FVIII and von Willebrand factor (VWF) are naturally bound together in circulation
  • Full sulfation of Tyrosine 1680 (Tyr1680) is vital for VWF-binding affinity and FVIII protection
  • NUWIQ is fully sulfated at Tyr1680, with high VWF-binding affinity and less than 1% unbound FVIII
  • Minimizing unbound FVIII in circulation may help reduce the risk of FVIII inhibitor development 1
