BlueCross BlueShield of Tennessee Medical Policy Manual

Inotuzumab Ozogamicin


0008-0100-XX Besponsa 0.9 MG SOLR (PFIZER U.S.)


Inotuzumab ozogamicin is a CD22-directed antibody-drug conjugate (ADC).  It consists of three components:  the IgG4 antibody inotuzumab which is specific for CD22, N-acetyl-gamma-calicheamicin which causes double stranded DNA breaks and an acid-cleavable covalent linker known as dimethylhydrazide.

Its anticancer activity is likely due to the binding of inotuzumab ozogamicin to CD22-expressing tumor cells followed by the internalization of the ADC-CD22 complex.  Within the cell, the N-acetyl-gamma-calicheamicin is released and activated, inducing double-strand DNA breaks leading to cell cycle arrest and death by apoptosis.





Inotuzumab ozogamicin is NOT considered medically appropriate for renewal
