Dosing and Usage

Dosing Overview1

Dose and duration of therapy depend on the patient’s weight, type and severity of hemorrhage, FVIII level, and presence of inhibitors.

  • Dose and frequency are adjusted according to the patient’s clinical response, individual needs, severity of deficiency, severity of hemorrhage, desired FVIII level, and presence of inhibitor, as well as the patient’s clinical condition.
  • Patients may vary in their pharmacokinetic (e.g., rate of absorption, bioavailability, distribution, metabolism, and excretion) and clinical responses to wilate.

Routine Prophylaxis (Preventive Care)

Exact dosing should be defined by the patient’s clinical status and response.

wilate Dosing for Routine Preventive Care in Hemophilia A

Recommended Dosage (IU*/kg body weight) Frequency of Infusions
20-40 IU/kg Every 2 to 3 days

*IU = International Unit

On-Demand Treatment of Hemorrhages

Recommended dosing regimen for on-demand treatment of bleeds is outlined in the below table.

wilate Dosing for Treatment of Hemorrhages in Hemophilia A

Type of Hemorrhage Recommended Dosage (IU/kg body weight) Frequency of Doses (hours) Duration of Therapy (days)
Minor 30 – 40 Repeat every 12 – 24 hours At least 1 day, until the hemorrhage has resolved
Moderate 30 – 40 Repeat every 12 – 24 hours 3 to 4 days or more, until the hemorrhage has resolved
Major 35 – 50 Repeat every 12 – 24 hours 3 to 4 days or more, until the hemorrhage has resolved
Life Threatening 35 – 50 Repeat every 8 – 24 hours Until threat has resolved

The physician may adjust the dose and management plan according to the extent and location of bleeding and the patient’s clinical condition. See Dosage and Administration, section 2.1 of full Prescribing Information.

Monitoring parameters

  • Plasma FVIII levels should be monitored periodically to evaluate individual patient response to the dosage regimen
  • If dosing studies have determined that a particular patient exhibits a lower/higher than expected response and shorter/longer half-life (the amount of time it takes for the concentration of a drug in the body to be reduced to 50%), the dose and the frequency of dosing should be adjusted accordingly
  • Failure to achieve the expected FVIII:C (coagulant activity) level or to control bleeding after an appropriately calculated dosage may indicate the development of an inhibitor (an antibody to FVIII:C). The inhibitor level should be quantified by appropriate laboratory procedures and its presence documented. Treatment with wilate in such cases must be individualized.
