Bardoxolone methyl, the C-28 methyl ester of 2-cyano-3,12-dioxoolean-1,9-dien-28-oic acid (CDDO) known as CDDO-Me or RTA 402, is one of the derivatives of synthetic triterpenoids. Bardoxolone methyl directly blocks IKKbeta activity and thereby the NF-kappaB pathway by interacting with Cys-179 in the IKKbeta activation loop. Binding of bardoxolone methyl to Kelch-like erythroid cell-derived protein with CNC homology-associated protein 1 (Keap1) disrupts its critical cysteine residues, leading to the release of the nuclear factor erythroid 2-related factor 2 (Nrf2), which hinders its ubiquitination and finally leads to its stabilization and nuclear translocation. In the nucleus, Nrf2 activates the transcription of phase 2 response genes, leading to a coordinated antioxidant and anti-inflammatory response. In addition, it acts as an antagonist of the peroxisome proliferator-activated receptor gamma. Through Keap1/Nrf2 and nuclear factor-κB pathways, this agent can modulate the activities of a number of important proteins that regulate inflammation, redox balance, cell proliferation and programmed cell death. This agent is generally well tolerated, but it may increase adverse cardiovascular events. Presently, it is being further tested for the treatment of patients with chronic kidney disease, cancer, and pulmonary arterial hypertension.

Single dose administration of 20, 60, and 80 mg bardoxolone methyl was safe and well-tolerated in healthy volunteers.
In a Phase I trial in cancer patients, bardoxolone methyl was found to have a slow and saturable oral absorption, a relatively long terminal phase half-life (39 hours at 900 mg/day), nonlinearity (dose-dependent) at high doses (600-1,300 mg/day), and high interpatient variability.
Phase 3 study of the long-term safety and tolerability of bardoxolone methyl in qualified patients with pulmonary hypertension: Bardoxolone methyl will be administered orally once daily at 10 mg until it becomes commercially available. Dose de-escalation (down to 5 mg) is permitted during the study, if indicated clinically.
