Ixazomib is an active metabolite of MLN9708, a second generation, boron containing peptide proteasome inhibitor (PI) with potential antineoplastic activity. Ixazomib binds to and inhibits the 20S catalytic core of the proteasome, thereby blocking the targeted proteolysis normally performed by the proteasome, which results in an accumulation of unwanted or misfolded proteins; disruption of various cell signaling pathways may follow, resulting in the induction of apoptosis. Compared to first generation PIs, second generation PIs may have an improved pharmacokinetic profile with increased potency and less toxicity. Proteasomes are large protease complexes that degrade unneeded or damaged proteins that have been ubiquinated.
Ixazomib is a Proteasome Inhibitor. The mechanism of action of ixazomib is as a Proteasome Inhibitor.

5.5 Absorption, Distribution and Excretion

Absorption

After oral administration, the time to reach maximum concentration in plasma was 1 hour. The mean absolute oral bioavailability is 58%.


Route of Elimination

62% in urine and 22% in feces.


Volume of Distribution

The steady-state volume of distribution is 543 L.


5.6 Metabolism/Metabolites

Metabolism of ixazomib is expected to be by CYP and non-CYP pathways, with no predominant CYP isozyme contribution. At higher than clinical concentrations, ixazomib was metabolized by multiple CYP isoforms with estimated relative contributions of 3A4 (42%), 1A2 (26%), 2B6 (16%), 2C8 (6%), 2D6 (5%), 2C19 (5%) and 2C9 (<1%).


5.7 Biological Half-Life

Terminal half-life is 9.5 days.


5.8 Mechanism of Action

Ixazomib is an N-capped dipeptidyl leucine boronic acid which reversibly inhibits the CT-L proteolytic (5) site of the 20S proteasome. At higher concentrations, ixazomib also seems to inhibit the proteolytic 1 and 2 subunits and to induce accumulation of ubiquitinated proteins.
