About Diabetic Nephropathy

Diabetic nephropathy (DN) is a leading cause of end-stage kidney disease. In the Unites States there are approximately 22 million diabetic patients, 40% of whom exhibit signs of DN. Clinically, DN is characterized by a progressive increase of protein in the urine, decrease in the glomerular filtration rate, increase in serum creatinine and ultimately End-Stage Renal Disease (ESRD) requiring dialysis or a kidney transplant. Although optimal control of blood pressure and metabolic risk factors is important in decreasing the progression of diabetic nephropathy, many diabetic patients still develop overt nephropathy and reach ESRD.

About Pyridorin®

Pyridorin is an investigational compound with a distinct chemical structure that inhibits the formation of advanced glycation end-products (AGE). AGEs have been implicated in the development of diabetic nephropathy. In people with diabetes, elevated glucose reacts with proteins to form complexes that are then deposited within the kidney leading to damage that interferes with normal kidney function. AGEs also lead to the generation of highly reactive molecules such as carbonyls and reactive oxygen species that can damage both the outside of the cell and important structures within the cell.

About PIONEER

The PIONEER program is focused on the significant unmet needs of patients with diabetic nephropathy. Data from over 650 subjects from Phase 2 studies was used to support the design of the Phase 3 PIONEER-311 study in type 2 diabetic patients with overt nephropathy. The PIONEER study design was agreed with the FDA using the Special Protocol Assessment (SPA) process, a binding agreement that the protocol design, clinical endpoints, planned conduct and statistical analyses are acceptable to support regulatory approval. In addition, Pyridorin has been granted Fast Track Designation by the FDA, a process designed to facilitate the development, and expedite the review, of drugs to treat serious conditions and fill an unmet medical need.
