XTEND-1 was a single-arm study, which may impact the interpretation of patient-reported outcome findings. The absence of a comparator arm may result in an under- or overestimation of treatment effect. Patient-reported nature of data may impact the reliability of findings. The PROMIS instrument has not been validated in hemophilia patients.

Study design:
Patient-reported outcomes of pain intensity and physical functioning were evaluated in patients receiving ALTUVIIIO prophylaxis in the prior Factor VIII prophylaxis group. The PROMIS Pain Intensity 3a instrument was used to assess pain, specifically, the first question that rates the worst pain experienced during the last 7 days. Physical functioning was assessed in patients ≥17 years old using the Physical-Health Score of Haem-A-QoL, which evaluated factors such as painful swellings, presence of joint pain, pain with movement, difficulty walking far, and needing more time to get ready.2

*Worst pain experienced during the last 7 days (1=no pain; 2=mild pain; 3=moderate pain; 4=severe pain; 5=very severe pain).2

LEARN ABOUT SAFETY

INDICATION

ALTUVIIIO® [antihemophilic factor (recombinant), Fc-VWF-XTEN fusion protein-ehtl] is a von Willebrand Factor (VWF) independent recombinant DNA-derived, Factor VIII concentrate indicated for use in adults and children with hemophilia A (congenital factor VIII deficiency) for:

  • Routine prophylaxis to reduce the frequency of bleeding episodes
  • On-demand treatment & control of bleeding episodes
  • Perioperative management of bleeding

Limitation of Use

ALTUVIIIO is not indicated for the treatment of von Willebrand disease.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

ALTUVIIIO is contraindicated in patients who have had severe hypersensitivity reactions, including anaphylaxis, to the product or its excipients.

WARNINGS AND PRECAUTIONS

  • Allergic-type hypersensitivity reactions, including anaphylaxis, may occur with ALTUVIIIO. Allergic-type hypersensitivity reactions were not reported in the clinical trials. Advise patients to discontinue use of ALTUVIIIO if hypersensitivity symptoms occur and contact a physician and/or seek immediate emergency care.
  • Formation of neutralizing antibodies (inhibitors) to Factor VIII is possible following administration of ALTUVIIIO. Neutralizing antibodies were not reported in the clinical trials. Monitor all patients for the development of Factor VIII inhibitors by appropriate clinical observations and laboratory tests.
  • If assessment of plasma Factor VIII activity is needed, it is recommended to use a validated one-stage clotting assay. The ALTUVIIIO Factor VIII activity level is overestimated by the chromogenic assay and a specific ellagic acid-based aPTT reagent in one-stage clotting assay by approximately 2.5-fold. If these assays are used, divide the result by 2.5 to approximate the patient's ALTUVIIIO Factor VIII activity level.

ADVERSE REACTIONS

The most common adverse reactions (>10% of subjects) reported in clinical trials were headache and arthralgia.
