Repaglinide + Metformin Superior to Nateglinide + Metformin in Treating Type 2 Diabetes: Presented at AACE

By Maury M. Breecher, PhD, MPH

SAN DIEGO, CA -- May 18, 2003 -- Patients with type 2 diabetes have significantly better fasting plasma glucose levels (FPG) and hemoglobin A1c (HbA1c) levels when treated with metformin combined with repaglinide rather than combined with nateglinide.

Philip Raskin, MD, professor of internal medicine, University of Texas Southwestern at Dallas, Tex, presented these findings here on May 16^th during the American Association of Clinical Endocrinologists 12^th Annual Meeting and Clinical Congress.

The parallelgroup, randomized, open-label trial, compared the efficacy and safety of repaglinide and nateglinide in combination with metformin for 16 weeks. The group enrolled 192 type 2 diabetic patients with mean ages of 55.9 and 45.3 respectively.

Mean change from baseline HbA1c in the repaglinide patients was –1.28 (P<0.001), almost double the –0.67 (P<0.001) mean change in the nateglinide group. FPG baseline mean for the repaglinide group was 189 compared to 191 for the nateglinide group. The mean change from those baselines was –31 for the repaglinide group compared to –21 for the nateglinide group.

"This research may help clinicians decide which of these shortacting nonsulfonylurea secretagogues to use in combination with metformin after failure of single oral-agent monotherapy," said Dr. Raskin.

This study was financed by Novo Nordisk Pharmaceuticals, Inc., Princeton, N.J.
