CSL Behring offers a next-generation treatment option for hemophilia A

As a patient-focused company, CSL Behring strives to create innovative therapies for the hemophilia community. That’s why we’ve developed long-lasting AFSTYLA, a next-generation Factor VIII therapy.

With twice-weekly dosing available,* AFSTYLA is the first and only recombinant Factor VIII that delivers proven, long-lasting bleed protection with a novel single-chain design. AFSTYLA also delivered zero bleeds (median AsBR) in all studied populations regardless of dosing regimen. Take a moment to explore all that AFSTYLA can offer your patients.

*FDA approved for dosing 2x–3x weekly dosing. Annualized spontaneous bleeding rate in clinical trials (IQR=0–2.4 for patients ≥12 years; 0–2.2 for patients <12 years).

Staying with CSL Behring and switching to AFSTYLA is simple for patients

All the support services and the reconstitution system your patients have come to rely on and trust with Helixate FS will remain in place for patients taking AFSTYLA. Services include:

  • My Access®—the co-pay program that provides up to $12,000 of out-of-pocket coverage to covered patients
  • CSL Behring AssuranceSM Program—helps make product available in case of lapse in insurance coverage for patients
  • My SourceSM Care Coordinator—at hand to help patients navigate the insurance process and answer any questions they may have
  • Mix2Vial® transfer and reconstitution system—the same as Helixate FS so their reconstitution routine can remain consistent
