Dose

  • Dosage and duration of treatment depend on the severity of factor VIII deficiency, the location and extent of the bleeding, and the patient's clinical condition. Careful control of replacement therapy is especially important in cases of major surgery or life-threatening bleeding episodes.
  • Each vial of ADVATE has the recombinant factor VIII potency in International Units (IU) stated on the label. The expected in vivo peak increase in factor VIII level expressed as IU/dL of plasma or percent of normal can be estimated using the following formulas:
    IU/dL (or % of normal) = [total dose (IU)/body weight (kg)] × 2 [IU/dL]/[IU/kg]
    OR
    Required dose (International Units) = body weight (kg) × desired factor VIII rise (IU/dL or % of normal) × 0.5 (IU/kg per IU/dL)

Examples (assuming patient's baseline factor VIII level is <1% of normal):

  1. A dose of 1750 IU ADVATE administered to a 70 kg patient should be expected to result in a peak postinfusion factor VIII increase of: 1750 IU × {[2 IU/dL]/[IU/kg]}/[70 kg] = 50 IU/dL (50% of normal).
  2. A peak level of 70% is required in a 40 kg child. In this situation, the appropriate dose would be 40 kg × 70 IU/dL/{[2 IU/dL]/[IU/kg]} = 1400 IU.
  • Base the dose and frequency on the individual clinical response. Patients may vary in their pharmacokinetic (e.g., half-life, in vivo recovery) and clinical responses to ADVATE. Although the dose can be estimated by the calculations above, whenever possible, perform appropriate laboratory tests including serial factor VIII activity assays [see Warnings and Precautions (5.3), Clinical Pharmacology (12.3)].

Control and Prevention of Bleeding Episodes

A guide for dosing ADVATE for the control and prevention of bleeding episodes is provided in Table 1. The goal of treatment is to maintain a plasma factor VIII activity level at or above the plasma levels (in % of normal or in IU/dL) outlined in Table 1.

Perioperative Management

A guide for dosing ADVATE during surgery (perioperative management) is provided in Table 2. The goal of treatment is to maintain a plasma factor VIII activity level at or above the plasma level (in % of normal or in IU/dL) outlined in Table 2.

Routine Prophylaxis

  • Use dose of 20 to 40 International Units of factor VIII per kg body weight every other day (3 to 4 times weekly).
  • Alternatively, use every third day dosing regimen targeted to maintain FVIII trough levels ≥1%.
  • Adjust dose based on the patient's clinical response.1,2

Preparation and Reconstitution

Preparation

  • Do not remove ADVATE or diluent vials from the external housing.
  • Always work on a clean surface and wash your hands before performing the procedures.
  • Examine the packaging containing ADVATE to ensure no damage or peeling of the lid is evident. Do not use if the lid is not completely sealed on the blister. Do not remove ADVATE or diluent vials from the external housing.

Reconstitution

  1. Allow the ADVATE package to reach room temperature.
  2. Open the package by peeling away the lid. Remove ADVATE from the package and verify that the expiration date on the label has not passed and the potency unit number is same as expected. Inspect parenteral drug products for discoloration and particulate matter. The ADVATE powder should be white to off-white in color and the diluent free from foreign particles. Do not use if the criteria are not met.
  3. Place the ADVATE on a flat surface with the diluent vial on top (Figure A). The diluent vial has a blue stripe. Do not remove the blue cap until instructed in a later step.
  4. With one hand holding the ADVATE housing, press down firmly on the diluent vial with the other hand until the system is fully collapsed and the diluent flows down into the ADVATE vial (Figure B). Do not tilt the system until the transfer is complete.
  5. Verify that diluent transfer is complete. Swirl gently until the powder is completely dissolved (Figure C). Do not shake. Do not refrigerate after reconstitution.

Administration

For intravenous injection after reconstitution only.

  • Inspect parenteral drug products for particulate matter and discoloration prior to administration. The solution should be clear and colorless in appearance. If not, do not use the solution and notify Takeda Pharmaceuticals U.S.A., Inc. immediately.
  • Administer ADVATE at room temperature within 3 hours of reconstitution.
  • Use plastic syringes with this product because proteins in the product tend to stick to the surface of glass syringes.
  1. Use aseptic technique.
  2. Remove the blue cap from the housing. Connect the syringe to the system (Figure D). Do not inject air into the ADVATE.
  3. Turn the system upside down (factor concentrate vial now on top). Draw the factor concentrate into the syringe by pulling the plunger back slowly (Figure E).
  4. Disconnect the syringe, attach a suitable needle, and inject intravenously as instructed. If a patient is to receive more than one ADVATE-BAXJECT III system or a combination of an ADVATE-BAXJECT II and an ADVATE-BAXJECT III system, the contents may be drawn into the same syringe.
  5. Administer ADVATE over a period of ≤5 minutes (maximum infusion rate 10 mL/min). Determine the pulse rate before and during administration of ADVATE. Should a significant increase in pulse rate occur, reducing the rate of administration or temporarily halting the injection usually allows the symptoms to disappear promptly.
