About Diabetic Nephropathy

Diabetic nephropathy is a chronic, degenerative disease of the kidney caused by diabetes. There are approximately 6 million patients with diabetic nephropathy in the United States (approximately 33% of diagnosed diabetics) and this population is expected to grow. Patients suffering from diabetic nephropathy progress to End Stage Renal Failure (and require dialysis) or death. There are currently no adequate treatments for this disease.

About Pyridorin®

Pyridorin inhibits pathogenic oxidative chemistries, which are collectively elevated in diabetic patients and induce pathological changes implicated in the development of diabetic nephropathy. Pyridorin inhibits a broad range of these chemistries which we believe accounts for its effectiveness in slowing the progression of nephropathy in diabetic patients as shown in our Phase 2 studies. Our lead drug candidate was also found to be safe and well tolerated in these same studies. Pyridorin has received FDA Fast Track designation and is currently being studied in a Phase 3 trial (PIONEER) in patients with diabetic nephropathy under a special protocol assessment (SPA) with the FDA.
