Lexicon to Present LX4211 Clinical and Preclinical Data at Diabetes Conference

Nov 03, 2011, 18:00 ET from Lexicon Pharmaceuticals, Inc.

THE WOODLANDS, Texas, Nov. 3, 2011 /PRNewswire/ -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), a biopharmaceutical company focused on discovering breakthrough treatments for human disease, announced today that Dr. David Powell, senior vice president of metabolism research, will present data from clinical and preclinical studies of LX4211, a dual inhibitor of sodium glucose transporters 1 and 2 (SGLT1 and SGLT2), at the Cambridge Healthtech Institute's Diabetes Drug Discovery conference in Boston, Massachusetts on Friday, November 4, 2011.

In clinical studies to date, LX4211 has demonstrated a favorable safety profile and beneficial effects on multiple parameters of glycemic control and cardiovascular health.  Recent studies in healthy subjects have shown that LX4211 substantially decreases postprandial glucose levels without hypoglycemia and substantially reduces triglycerides, results that have not been reported for SGLT2-selective inhibitors.  Data from a mechanistic study in patients with type 2 diabetes demonstrated that a single dose of LX4211 significantly increased circulating levels of GLP-1 (active and total) and PYY, important regulators of glycemic and appetite control.  In addition, postprandial release of GLP-1 and PYY from the gastrointestinal (GI) tract has been observed in preclinical studies of SGLT1 knockout mice but not in SGLT2 knockout mice, indicating that inhibition of SGLT1 function may trigger the postprandial release of these important regulators of glycemic and appetite control.
