( 1 ) Limitation of Use ALTUVIIIO is not indicated for the treatment of von Willebrand disease.
Posología
2 DOSAGE AND ADMINISTRATION For intravenous use after reconstitution only. For intravenous use only. Each ALTUVIIIO vial label states Factor VIII activity in international units (IU or unit). ( 2.1 ) For routine prophylaxis: 50 IU/kg once weekly. ( 2.1 ) For on-demand treatment and control of bleeding episodes and perioperative management: 50 IU/kg ( 2.1 ) Estimated Increment of Factor VIII (IU/dL or % of normal) = 50 IU/kg × 2 (IU/dL per IU/kg) ( 2.1 ) To achieve a specific target Factor VIII activity level, use the following formula: Dosage (IU) = Body Weight (kg) × Desired Factor VIII Increase (IU/dL or % normal) × 0.5 (IU/kg per IU/dL). ( 2.1 ) 2.1 Dose Each ALTUVIIIO vial label states the Factor VIII potency in international units (IU). One IU corresponds to the Factor VIII activity contained in one milliliter of normal human plasma, as defined by the current World Health Organization (WHO) international standard for Factor VIII concentrate. Potency assignment for ALTUVIIIO is determined using an activated partial thromboplastin time (aPTT)-based one-stage clotting assay. It is recommended to use a validated one-stage clotting assay to measure ALTUVIIIO Factor VIII activity in plasma. 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 [see Warnings and Precautions (5.3) ]. For the dose of 50 IU/kg, the expected in vivo peak increase in Factor VIII level expressed as IU/dL (or % of normal) is estimated using the following formula: Estimated Increment of Factor VIII (IU/dL or % of normal) = 50 IU/kg × 2 (IU/dL per IU/kg) To achieve a specific target Factor VIII activity level, use the following formula: Dosage (IU) = Body Weight (kg) × Desired Factor VIII Increase (IU/dL or % normal) × 0.5 (IU/kg per IU/dL). Routine Prophylaxis The recommended dosing for routine prophylaxis for adults and children is 50 IU/kg of ALTUVIIIO administered once weekly. On-demand Treatment and Control of Bleeding Episodes ALTUVIIIO dosing for the on-demand treatment and control of bleeding episodes is provided in Table 1. Table 1: Dosing for On-demand Treatment and Control of Bleeding Episodes Type of Bleeding Recommended Dose Additional Information Minor and Moderate For example: Uncomplicated joint bleeds, minor muscular bleeds, mucosal or subcutaneous bleeds Single dose of 50 IU/kg For minor and moderate bleeding episodes occurring within 2 to 3 days after a prophylactic dose, a lower dose of 30 IU/kg dose may be used. Additional doses of 30 or 50 IU/kg every 2 to 3 days may be considered. Major For example: Intracranial, retroperitoneal, iliopsoas and neck bleeds, muscle bleeds with compartment syndrome and bleeds associated with a significant decrease in the hemoglobin level Single dose of 50 IU/kg Additional doses of 30 or 50 IU/kg every 2 to 3 days can be considered. For resumption of prophylaxis (if applicable) after treatment of a bleed, it is recommended to allow an interval of at least 72 hours between the last 50 IU/kg dose for treatment of a bleed and resuming prophylaxis dosing. Thereafter, prophylaxis can be continued as usual on the patient's regular schedule. Perioperative Management ALTUVIIIO dosing for perioperative management is provided in Table 2. Table 2: Dosing for Perioperative Management Type of Surgery Pre-operative Dose Post-operative Dose Minor For example: Tooth extraction Single dose of 50 IU/kg An additional dose of 30 or 50 IU/kg after 2 to 3 days may be considered. Major For example: Intracranial, intra-abdominal, joint replacement surgery, or complicated dental procedures. Single dose of 50 IU/kg Additional doses of 30 or 50 IU/kg every 2 to 3 days may be administered as clinically needed for perioperative management. 2.2 Preparation and Reconstitution Use aseptic technique and a flat work surface during the reconstitution procedure. Allow the ALTUVIIIO vial, containing the white t
Contraindicaciones
4 CONTRAINDICATIONS ALTUVIIIO is contraindicated in patients who have had severe hypersensitivity reactions, including anaphylaxis, to the product or its excipients [see Description (11) ] . Do not use in patients who have had severe hypersensitivity reactions, including anaphylaxis, to ALTUVIIIO or excipients of ALTUVIIIO. ( 4 )

8.1 Pregnancy Risk Summary There are no data with ALTUVIIIO use in pregnant women to inform a drug-associated risk. Animal developmental and reproductive studies have not been conducted with ALTUVIIIO. Therefore, it is not known whether ALTUVIIIO can affect reproductive capacity or cause fetal harm when given to pregnant women. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.
Efectos adversos
6 ADVERSE REACTIONS Most common adverse reactions (incidence >10%) are headache and arthralgia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Bioverativ Therapeutics Inc. (A SANOFI COMPANY) at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data described in this section reflects exposure to ALTUVIIIO in two clinical studies, Study 1 and Study 2 and are pooled for analysis. In Study 1, a total of 159 previously treated patients (PTPs) (134 adults and 25 adolescents) with severe Hemophilia A) received at least one dose of ALTUVIIIO for either routine prophylaxis, on-demand treatment of bleeding episodes or perioperative management. A total of 152 (96%) patients achieved at least 25 exposure days and 115 (72%) patients achieved at least 50 exposure days with a median of 53.0 (range 2–63) for both exposure days and injections per patient. Overall exposure was monitored for a total of 151.5 patient-years [see Clinical Studies (14) ] . In Study 2, the safety of ALTUVIIIO was evaluated in 74 male PTPs <12 years of age with severe hemophilia A who received at least one dose of ALTUVIIIO. Sixty-six (89.2%) patients achieved at least 50 exposure days with a median of 53.0 (range 3–72). Adverse events were monitored for a total of 210.7 patient-years in 2 completed clinical studies in PTPs. Adverse drug reactions (ADRs) (summarized in Table 3) were reported in 79 (33.9%) of the 233 patients treated with routine prophylaxis or on-demand therapy. The most common ADRs (>10%) in adults and adolescents were headache (20.1%) and arthralgia (16.4%). In children below 12 years, pyrexia (12.2%) was the most common ADR (>10%). In the studies, no inhibitors to FVIII were detected and no ADRs of anaphylaxis were reported. The most common adverse reactions (>10% of patients) reported in clinical trials were headache and arthralgia. Table 3: Adverse Reactions with Frequency of ≥3% Reported in ALTUVIIIO Studies Pooled data from Study 1 and Study 2 including 233 patients across the adult and adolescent and pediatric studies. MedDRA System Organ Class Adverse Drug Reactions Number of Patients n (%) (N = 233) Nervous system disorders Headache 35 (15) Musculoskeletal and connective tissue disorders Arthralgia 31 (13) Pain in extremity 10 (4) Back pain 9 (4) General disorders and administration Pyrexia 10 (4) Gastrointestinal disorders Vomiting 7 (3) Thromboembolic events occurred in 1% (3/261) of patients in the long-term safety extension study; these three patients had pre-existing risk factors. 6.2 Postmarketing Experience The following adverse reactions have been identified during the post approval use of ALTUVIIIO. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and lymphatic system disorders: Factor VIII inhibitor development [see Warnings and Precautions (5.2) ]. Immune system disorders: Hypersensitivity reactions, including anaphylaxis [see Warnings and Precautions (5.1) ].
