Ixazomib (trade name Ninlaro) is a drug for the treatment of multiple myeloma, developed by Takeda. It acts as a proteasome inhibitor and has orphan drug status in the US.

On November 20, 2015, the U.S. Food and Drug Administration approved ixazomib for use in combination with lenalidomide and dexamethasone for the treatment of multiple myeloma after at least one prior therapy.^[2]

Mechanism

Ixazomib is a peptide analogue that reversibly inhibits the protein proteasome subunit beta type-5 (PSMB5), which is part of the 20S proteasome complex.^[3]

Ixazomib citrate—a prodrug for ixazomib

Ixazomib citrate is a prodrug which rapidly hydrolyzes under physiological conditions to its biologically active form, ixazomib.^[1]
