Important Safety Information for AFSTYLA
AFSTYLA®, Antihemophilic Factor (Recombinant), Single Chain, is contraindicated in patients who have had life-threatening hypersensitivity reactions to AFSTYLA or its excipients, or to hamster proteins.
AFSTYLA is for intravenous use only. AFSTYLA can be self-administered or administered by a caregiver with training and approval from a healthcare provider or hemophilia treatment center. Higher and/or more frequent dosing may be needed for patients under 12 years of age.
Hypersensitivity reactions, including anaphylaxis, are possible. Advise patients to immediately report symptoms of a hypersensitivity reaction. If symptoms occur, discontinue AFSTYLA and administer appropriate treatment.
Formation of neutralizing antibodies (inhibitors) has been reported following administration of AFSTYLA; previously untreated patients (PUPs) are at greater risk. If expected plasma Factor VIII activity levels are not attained, or if bleeding is not controlled with an appropriate dose, perform an assay that measures Factor VIII inhibitor concentration.
Monitor plasma FVIII activity using a chromogenic assay or one-stage clotting assay. If one-stage clotting assay is used, multiply result by a conversion factor of 2 to determine FVIII activity level.
The most common adverse reactions reported in clinical trials (>0.5%) were dizziness and hypersensitivity.
Indications for AFSTYLA
AFSTYLA®, Antihemophilic Factor (Recombinant), Single Chain, is indicated in adults and children with hemophilia A (congenital Factor VIII deficiency) for:
- On-demand treatment and control of bleeding episodes
- Routine prophylaxis to reduce frequency of bleeding episodes
- Perioperative management of bleeding
AFSTYLA is not indicated for the treatment of von Willebrand disease.
