MedKoo CAT#: 202530

CAS#: 218600-53-4

Description: Bardoxolone methyl (also known as “RTA 402” and “CDDO-methyl ester”) is an orally-available first-in-class synthetic triterpenoid belonging to the antioxidant inflammation modulator (AIM) class. It is the most potent known inducer of the Nrf2 pathway to enter clinical development and works to suppress both oxidative stress and inflammation. Bardoxolone methyl is currently being developed by Reata Pharmaceuticals, Inc. in partnership with Abbott Laboratories and Kyowa Hakko Kirin, for the treatment of advanced chronic kidney disease (CKD) in type 2 diabetes mellitus patients.

Additional Information

Bardoxolone methyl, previously known as RTA 402, is the lead molecule emerging from ReataÂ’s platform of Antioxidant Inflammation Modulators (AIMs). The AIMs are the most potent known inducers of Nrf2, an important emerging biological target that controls the production of many of the bodyÂ’s antioxidant and detoxification enzymes. There is a strong biological rationale for the use of agents targeting Nrf2 to treat renal and cardiovascular disease. Chronic oxidative stress-mediated inflammation is known to play an important role in the degeneration of kidney function. Based on data from three clinical studies demonstrating improvements in patientsÂ’ markers of kidney function and potential disease-modifying activity, bardoxolone has been advanced to late-stage clinical development and is currently undergoing a pivotal Phase 2b trial in chronic kidney disease patients with type 2 diabetes mellitus.
