Select storage requirements1

Do not freeze

Store ALTUVIIIO in powder form at 2°C to 8°C (36°F to 46°F). Do not freeze to avoid damage to the prefilled diluent syringe.

Home temperature

ALTUVIIIO may be stored at room temperature, not to exceed 30°C (86°F), for a single period of up to 6 months, within the expiration date printed on the label. After storage at room temperature, do not return the product to the refrigerator.

Restrict sunlight

Store ALTUVIIIO in the original package to protect vials from light.

Trash bin

Discard ALTUVIIIO if it is not used within 3 hours of reconstitution, if solution is cloudy or has particulate matter, or any drug is unused.

For additional information on storage, please see Section 16 of the Prescribing Information.

Dosage strengths1

ALTUVIIIO is available in 6 vial strengths to optimize administration.
These include single-dose vials containing nominally 250, 500, 1000, 2000, 3000, or 4000 international units (IU) per vial.

There’s no need for routine pharmacokinetic testing with ALTUVIIIO1

Sanofi has contracted with LabCorp (Esoterix) to provide a central lab to perform standardized, one-stage clotting assays with a national network of local laboratories for specimen collection at no extra cost to the patient or healthcare provider.

For more information about monitoring with LabCorp, contact your ALTUVIIIO Representative.

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

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 are 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.
