Imiglitazar (also known as TAK-559) is a dual peroxisome proliferator-activated receptor (PPAR) alpha and gamma agonist patented by Japanese pharmaceutical company Takeda Chemical Industries for the prevention or treatment of diabetes mellitus, hyperlipemia, insulin insensitivity, insulin resistance, and impaired glucose tolerance. Imiglitazar shows potent hypoglycemic and hypolipidemic activity and has been studied in clinical trials in treating subjects receiving a stable dose of insulin to control type 2 diabetes mellitus. Unfortunately, Imiglitazar shows hepatotoxicity and has never been marketed.

Naveglitazar is an oral dual peroxisome proliferator-activated receptor (PPAR) agonist, which was under development with Ligand Pharmaceuticals for the treatment of type 2 diabetes mellitus. Naveglitazar is a nonthiozolidinedione peroxisome proliferator-activated receptor (PPAR) α-γ dual, γ-dominant agonist that has shown glucose-lowering potential in animal models and in the clinic. Naveglitazar had been in phase II clinical trials for the once-daily oral treatment of type 2 diabetes, however, the development was discontinued.
