Class/mechanism: Second-generation reversible proteasome inhibitor; preferentially binds and inhibits the chymotrypsin-like activity of the beta 5 subunit of the 20S proteasome. Ixazomib interferes with degradation of ubiquitinated proteins, which disrupts normal homeostatic mechansims, leading to cell death. The tissue distribution profile of ixazomib may be different than Bortezomib (Velcade) due to a shorter 20S proteasome dissociation half-life. Upon exposure to aqueous solutions, ixazomib/MLN9708 hydrolyzes to MLN2238, the active form.
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.
