Lexicon Announces Publication of Results of Two Studies of LX4211 in Patients with Type 2 Diabetes in the Journal Clinical Pharmacology & Therapeutics

Lexicon Pharmaceuticals, Inc.

announced today the publication of results from two initial trials of LX4211 in patients with type 2 diabetes in the online edition of the journal Clinical Pharmacology & Therapeutics. The paper, containing results from both trials, is entitled, "LX4211, a Dual SGLT1/SGLT2 Inhibitor, Improved Glycemic Control in Patients with Type 2 Diabetes in a Randomized, Placebo-controlled Trial," and will also appear in an upcoming print edition of the journal. A link to the online article can be accessed at http://www.nature.com/clpt/journal/vaop/ncurrent/full/clpt201258a.html. "This publication represents the first peer-reviewed description of SGLT1 inhibition stimulating GLP-1 and PYY release in man," said Dr. Brian Zambrowicz, Lexicon's executive vice president and chief scientific officer. "Since LX4211 also inhibits SGLT2, the rapid and significant glycemic control and metabolic benefits observed may be attributed to effective dual inhibition of these two targets."
