THE WOODLANDS, Texas, June 14, 2014 /PRNewswire/ -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), presented data at the 74th Scientific Sessions of the American Diabetes Association (ADA) in San Francisco on LX4211, an oral, first-in-class, dual inhibitor of sodium glucose transporters 1 and 2 (SGLT1 and SGLT2) that is designed to lower blood glucose levels through two insulin-independent mechanisms of action.  Results presented from a clinical study showed that LX4211 significantly reduced postprandial glucose levels in type 2 diabetes patients with moderate to severe renal impairment.

In a double-blind, randomized, placebo-controlled, parallel-group study with 31 patients, LX4211 provided statistically significant reductions (p=0.003) in postprandial glucose in type 2 diabetes patients with moderate to severe renal impairment.  In a sub-group analysis of patients with the most advanced renal impairment, defined as those with a glomerular filtration rate (GFR) of less than 45 ml/min/1.73 m2, LX4211 similarly reduced postprandial glucose as compared to placebo (p=0.002).  Exhibiting its inhibition of SGLT1, LX4211 produced significant elevations in both total GLP-1 (p=0.017) and active GLP-1 (p=0.042) across all patients.  There were no serious adverse events and no discontinuations due to adverse events during the study.

In an additional presentation at ADA, Lexicon presented data showing that LX4211 improved glycemic control in mice with poorly controlled type 1 diabetes.  LX4211 significantly lowered blood glucose levels in both the low dose (2 mg/kg LX4211) and high dose (30 mg/kg LX4211) groups while reducing the occurrences of hypoglycemia.  In addition, LX4211 significantly slowed the rise in HbA1c levels as compared to vehicle-treated mice with poorly controlled type 1 diabetes.
