Plain-language summary
A plain-language read of the study’s main message and where it applies.
Study focus
The Phase 2 study evaluated bardoxolone methyl in patients with chronic kidney disease and type 2 diabetes, showing a significant increase in GFR compared to placebo.
Improving kidney function in patients with chronic kidney disease and type 2 diabetes is crucial, as it can slow disease progression and reduce the risk of complications. The significant improvement in GFR with bardoxolone methyl suggests potential benefits for managing these patients, although monitoring for adverse effects is essential.
The study's sample size and generalizability may be limited. Potential confounding factors were not fully addressed. Adverse event reporting may not capture all relevant data.

Bardoxolone methyl led to a mean increase in GFR of 5.95 ml/min per 1.73 m².
A significant intergroup difference in GFR of 6.64 ml/min per 1.73 m² was observed (P = 0.008).
Increases in the albumin/creatinine ratio were noted in the bardoxolone methyl group compared to placebo.
The placebo group experienced a mean decrease in GFR of -0.69 ml/min per 1.73 m².
