Phase:
PHASE2
Brief Summary
To determine the effects of three different doses of bardoxolone methyl administered orally on the kidney function (glomular filtration rate) in patients with diabetic nephropathy.
Detailed Description
Bardoxolone methyl is an Antioxidant Inflammation Modulator in clinical development for inflammation and cancer-related indications that inhibits immune-mediated inflammation by restoring redox homeos...
