Bardoxolone methyl (NSC 713200; RTA 402; CDDO Methyl ester) is a synthetic triterpenoid compound with potential antineoplastic and anti-inflammatory activities, acting as an activator of the Nrf2 pathway and an inhibitor of the NF-κB pathway.

Nrf2^[1]

Bardoxolone methyl (30 mg/kg, p.o.) decreases renal expression of megalin but not cubilin, increases creatinine clearance and urinary albumin-to-creatinine ratios, and induces Nrf2 cytoprotective targets in cynomolgus monkeys^[1]. Bardoxolone methyl induces overall favorable effects on the heart via its improvement in eGFR in both animal models and clinical trials^[2].

Two separate in-life studies are conducted in cynomolgus monkeys. In one study, cynomolgus monkeys (n=9/gender/dose group) are administered amorphous bardoxolone methyl by oral gavage, using sesame oil as the vehicle, at 5, 30, and 300 mg/kg once daily for 12 months in a GLP environment. Observations for morbidity, mortality, injury, and the availability of food and water are conducted twice daily for all animals. Clinical observations and body weights are conducted and recorded weekly. Weight data are analyzed by calculating the area under the weight versus time curve using the linear trapezoidal method. Blood samples for clinical chemistry evaluations are collected from all animals pretest and from all animals prior to interim (6-month) and terminal (12-month) necropsies. An additional group of monkeys for each dose group are allowed to recover for 4 weeks.
