ADAMTS13, recombinant-krhn (Adzynma)
Section:

ADAMTS13, recombinant-krhn (Adzynma)is a human recombinant form of the endogenous rADAMTS13 “A disintegrin and metalloproteinase with thrombospondin motifs 13.” The ADAMTS13 is a protein in the blood that is involved with blood clotting. A lack of activity or deficiency in this enzyme causes congenital thrombotic thrombocytopenic purpura (cTTP), a rare, chronic clotting disorder where blood clots form in small blood vessels throughout the body. Adzynma replaces the deficient ADAMTS13 in pediatric and adult individuals with cTTP which prevents the excessive blood clotting and related disease complications.

Policy Position

ADAMTS13, recombinant-krhn (Adzynma) may be considered medically necessary for adult and pediatric individuals when the following criteria are met:

  • Confirmed diagnosis of congenital thrombotic thrombocytopenic purpura (cTTP) suggested by the following
    • Deficiency in ADAMTS13 enzyme determined by genetic testing; and
    • Measured ADAMTS13 activity less than 10% (may exceed 10% if individual is receiving prophylactic plasma infusion therapy); and
  • Treatment is utilized for one of the following:
    • Prophylactic enzyme replacement therapy; or
    • On- demand enzyme replacement therapy; and
  • Individual does not display signs of severe TTP defined by both of the following:
    • Platelet count less than 100,000/mcL; and
    • Elevation of lactate dehydrogenase (LDH) greater than two (2) times the upper limit of normal (ULN); and
  • Prescribed or in consultation with a hematologist, oncologist, intensive care specialist, or specialist in rare genetic hematologic diseases; and
  • Individual has not been diagnosed with any other TTP-like disorder (microangiopathic hemolytic anemia), including acquired TTP; and
  • Initial authorization will be for a period of six (6) months.

Reauthorization Criteria

Continuation of therapy with ADAMTS13, recombinant-krhn (Adzynma) may be considered medically necessary when the following criteria are met:

  • Prescribed or in consultation with a hematologist, oncologist, intensive care specialist, or specialist in rare genetic hematologic diseases; and
  • Individual has demonstrated a positive clinical response documented by reduction in acute or subacute TTP events, improvement in TTP manifestations, platelet counts, microangiopathic hemolytic anemia episodes, or clinical symptoms (i.e. confusion, seizures, renal dysfunction, etc.) ; and
  • Reauthorization will be for a period of 12 months.

The use of ADAMTS13, recombinant-krhn (Adzynma) not meeting the criteria as indicated in this policy is considered not medically necessary.
