NephroGenex Reaches Agreement with the FDA on a Subpart H Phase 3 Program for Pyridorin™

RESEARCH TRIANGLE PARK, N.C., Nov. 7, 2011 /PRNewswire/ -- NephroGenex, Inc., a privately held drug development company, today announced that it has reached an agreement with the FDA on the design of a new Phase 3 Subpart H program that evaluates Pyridorin™ in diabetic nephropathy patients.  This Subpart H program uses a novel surrogate endpoint based on an increase in serum creatinine (SCr), and provides for an accelerated regulatory pathway to approval.

The new surrogate endpoint was determined from a comprehensive analysis of prior large clinical trials in diabetic nephropathy patients that demonstrated a highly significant relationship between increases in SCr and the future progression of patients to end stage renal disease (ESRD).

In the Pyridorin™ Phase 3 Subpart H program, the FDA has agreed that approval will be based on a new surrogate endpoint that includes SCr changes after one year that predict progression to ESRD.  These patients will subsequently be followed to confirm the clinical benefit of Pyridorin™ in delaying progression to ESRD.  The patient population for the study will be type 2 diabetic patients with overt nephropathy who are on an established standard of care consisting of adequate blood pressure control and a stable regimen of ACEi/ARB therapy.

Diabetic kidney disease afflicts approximately one-third of all diabetics and is the major cause of ESRD, which is a significant component of healthcare expenditures.  Mortality rates for ESRD patients can reach 20% annually.  Pyridorin™ has been awarded Fast Track status by the FDA due to the unmet medical need of patients with this life-threatening disease.
