NephroGenex Announces Successful Results from Toxicity Study of Intravenous Pyridorin

1 pyridoxamine dihydrochloride

RALEIGH, NC, USA I November 4, 2015 I NephroGenex, Inc. (Nasdaq: NRX), a pharmaceutical company focused on the development of therapeutics to treat kidney disease, today announced successful results from a preclinical toxicity study of intravenous Pyridorin® being developed to treat acute kidney injury (AKI). Male and female Sprague-Dawley rats given 50, 100 and 200 mg/kg of Pyridorin (Pyridoxamine Dihydrochloride) once daily by intravenous infusion over 30 minutes for seven consecutive days, were free of any clinical signs of intolerance or toxicity to the drug. Key parameters evaluated included clinical signs, functional observational battery tests, body weight, food consumption, hematological parameters, serum chemistry and urinalysis parameters, gross necropsy findings, and histology.

The study also showed that there were no Pyridorin-related gross or microscopic findings in the nervous system (brain, spinal cord, spinal nerve roots/ganglia, and peripheral nerves). These findings add to the body of evidence that has demonstrated a consistent absence of treatment-emergent neuropathy in non-clinical and clinical studies with Pyridorin. This is in contrast with structurally distinct pyridoxine that has been associated with neurotoxicity in preclinical studies and in reports of patients taking mega-doses (2-5 g/day) for prolonged period ranging from 2-40 months.

“The results of this intravenous Pyridorin study will be used to support an IND filing, anticipated for later this year, of I.V. Pyridorin for the treatment of acute kidney injury,” commented Dr. Jaikrishna Patel, Chief Medical Officer.

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.
