63459-0177-XX Synribo 3.5 MG SOLR (CEPHALON)
Omacetaxine mepesuccinate is an antineoplastic agent categorized as a protein synthesis inhibitor. It is prepared in a semi-synthetic process from cephalotaxine, an extract of the leaves of the plum yew, Cephalotaxus sp. The mechanism of action is not fully understood, but its activity inhibits protein synthesis independently of direct Bcr-Abl binding, Because of this, omacetaxine mepesuccinate shows activity against disease in the failure of tyrosine kinase inhibitors (TKI).
Omacetaxine mepesuccinate for the treatment of chronic myeloid leukemia (CML) is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
Omacetaxine mepesuccinate for the treatment of other conditions/diseases is considered investigational.
Omacetaxine mepesuccinate is considered medically appropriate if ALL of the following criteria are:
Diagnosis of chronic myeloid/myelogenous leukemia (CML)
Individual is 18 years of age or older
Disease is confirmed by either a Philadelphia chromosome-positive (Ph+) OR BCR-ABL1 positive laboratory test result
Used as single agent therapy
Disease is ANY ONE of the following:
Advanced disease progression into chronic or accelerated phase
Post-allogeneic stem cell transplant if ANY ONE of the following:
Follow-up therapy with molecular relapse (BCR-ABL1 transcript positive) following complete cytogenetic response (CCyR)
Follow-up therapy with relapse or those who are not in CCyR
T315I mutation positive
Individual is resistant, intolerant or had an inadequate response to prior tyrosine kinase inhibitor (TKI) therapies consisting of a 3 month trial or longer, with a minimum of TWO of the following: bosutinib, imatinib, dasatinib, ponatinib, or nilotinib
Omacetaxine mepesuccinate is considered medically appropriate for renewal if ALL of the following criteria are met:
Individual continues to meet initial approval criteria
Absence of unacceptable toxicity from the drug including severe neutropenia; and/or thrombocytopenia; hemorrhage (including cerebral and gastrointestinal); hyperglycemia
Individual has been adherent to therapy
Treatment response as indicated by ANY ONE of the following:
BCR-ABL1 (IS) transcript levels:
≤ 10% at 3 months
≤ 10% at 6 months
< 1% at 12 months
< 0.1% beyond 12 months
NOTE: cytogenetic assessment of response may be used if quantitative RT-PCR (QPCR) using International Scale (IS) for BCR-ABL1 is not available
