3. Initial Approval Criteria ^1-3,8,10-14

Coverage is provided in the following conditions:

• Diagnosis of congenital factor VIII deficiency has been confirmed by blood coagulation testing; AND

Hemophilia A (congenital factor VIII deficiency) with inhibitors † Ф

• Patient has inhibitors to Factor VIII with a current or historical titer of ≥ 5 Bethesda Units (BU)**; AND
• Must be used as routine prophylaxis to prevent or reduce the frequency of bleeding episodes; AND
  • Used as primary prophylaxis in patients with severe factor VIII deficiency (factor VIII level of <1%); OR
  • Used as secondary prophylaxis in patients with at least TWO documented episodes of spontaneous bleeding into joints; AND
• Not used in combination with Immune Tolerance Induction (ITI); AND
  • Patient has had at least two documented episodes of spontaneous bleeding into joints; OR
  • Patient had a documented trial and failure of Immune Tolerance Induction (ITI); OR
  • Patient had a documented trial and failure of, or is currently on, routine prophylaxis with a bypassing agent (i.e., NovoSeven, Feiba)

**Note: Patients with inhibitor titer levels >0.6 BU to <5 BU who are not responding to or are not a candidate for standard factor replacement, will be evaluated on a case-by-case basis.

Hemophilia A (congenital factor VIII deficiency) without inhibitors † Ф

• Must be used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes; AND
• Used as treatment in one of the following:
  • • Primary prophylaxis in patients with severe factor VIII deficiency (factor VIII level of <1%); OR
    • Secondary prophylaxis in patients with at least TWO documented episodes of spontaneous bleeding into joints; AND
• Patient is not a suitable candidate for treatment with shorter half-life Factor VIII (recombinant) products at a total weekly dose of 100 IU/kg or less (as attested by the prescribing physician with appropriate clinical rationale)

† FDA Approved Indication(s); ‡ Compendia Recommended Indication(s); Ф Orphan Drug

4. Renewal Criteria ^1-3,8

Coverage can be renewed based upon the following criteria:

• Patient continues to meet the indication-specific relevant criteria such as concomitant therapy requirements (not including prerequisite therapy), performance status, etc. identified in section III; AND
• Absence of unacceptable toxicity from the drug. Examples of unacceptable toxicity include: thrombotic microangiopathy, thromboembolic events (thromboembolism, pulmonary embolism), development of neutralizing antibodies (inhibitors), etc.; AND
• Patient has demonstrated a beneficial response to therapy (i.e., the frequency of bleeding episodes has decreased from pre-treatment baseline)
