Lexicon Pharmaceuticals Reports 2008 Fourth Quarter and Full Year Financial Results

Conference Call and Webcast At 11:00 a.m. Eastern Time


THE WOODLANDS, Texas, Feb. 25, 2009 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq:LXRX), a biopharmaceutical company focused on discovering and developing breakthrough treatments for human disease, today updated its drug development progress and reported financial results for the three months and year ended December 31, 2008.

"In 2008, the company made significant progress in moving multiple drug development programs forward," said Dr. Arthur T. Sands, president and chief executive officer of Lexicon. "As part of our focus on the development of our pipeline, we streamlined operations and concentrated our resources on our most promising programs. We look forward to reporting data from several of our programs as they progress through clinical trials this year for irritable bowel syndrome, carcinoid syndrome, rheumatoid arthritis, and diabetes."

Key Developments of 2008



 * Lexicon initiated a Phase 2a clinical trial of its LX1031 drug
   candidate for non-constipating irritable bowel syndrome (IBS) in
   December 2008.  The trial is designed as a double-blind,
   randomized, placebo-controlled study to evaluate the safety and
   tolerability of LX1031 and its effects on symptoms associated with
   IBS.  In trials completed to date, all dose levels and dosing
   regimes were well tolerated with infrequent adverse events observed.

 * Lexicon completed dosing in a Phase 2a clinical trial of its LX6171
   drug candidate for cognitive disorders.  Although the compound was
   well tolerated, there was no clear demonstration of activity for
   the various cognitive domains evaluated.  The target of LX6171
   continues to be of interest, as this pathway has recently been
   associated with schizophrenia in human genetic studies.  While the
   company does not intend to pursue further development at this time,
   it plans to evaluate interest from third parties in the compound
   and its target for other neurobehavioral indications.

 * Lexicon completed dosing in a Phase 1b clinical trial of its LX1032
   drug candidate for carcinoid syndrome.  LX1032 was well tolerated
   at all doses and demonstrated a potent reduction in both blood
   serotonin levels and urinary 5-HIAA, a marker of serotonin
   biosynthesis.  Based on the results from this study, Lexicon is
   planning to initiate a Phase 2 study in patients with carcinoid
   syndrome in the first quarter of 2009.  In June 2008, Lexicon
   received Fast Track designation from the U.S. Food and Drug
   Administration (FDA) for development of LX1032.

 * Lexicon completed a Phase 1b clinical trial of its LX2931 drug
   candidate for autoimmune disorders.  In the trial, LX2931 was well
   tolerated at all doses tested.  A dose-dependent reduction in
   circulating lymphocytes was observed, confirming the mechanism of
   action of LX2931 in regulating lymphocyte trafficking.  Lexicon
   initiated a drug-drug interaction study with methotrexate in
   patients with rheumatoid arthritis in the first quarter of 2009.

 * Lexicon filed an investigational new drug (IND) application with
   the FDA for LX4211, an oral small molecule drug candidate for
   diabetes.  The company initiated a Phase 1 clinical trial of LX4211
   in January 2009.  The trial is planned as a double-blind,
   randomized, placebo-controlled, ascending single- and multiple-dose
   study to evaluate the safety, tolerability, and pharmacokinetics of
   LX4211 in healthy volunteers.

 * Lexicon initiated formal preclinical development of LX7101, a new
   drug candidate for glaucoma, in preparation for the planned filing
   of an IND application with the FDA.  LX7101 is a small molecule
   compound that may have application in treating glaucoma by lowering
   intraocular pressure through a new mechanism of action that
   enhances the eye's fluid outflow facility.  Impairment of fluid
   outflow is thought to be a major contributing factor to the higher
   incidence of glaucoma that is observed as people age.

 * Lexicon implemented reorganizations that reduced personnel and
   related expenditures in 2008 and early 2009.  These reorganizations
   were designed to focus Lexicon's resources on its most advanced
   drug discovery and development programs.  As a result of the May
   2008 reorganization, Lexicon reduced its expenses by approximately
   $10 million on an annualized basis.  As part of the January 2009
   reorganization, Lexicon expects to reduce its expenses by an
   additional approximately $8 million, net of severance costs, for
   the balance of 2009 and approximately $11 million on an annualized
   basis.

Financial Results

Revenues: Lexicon's revenues for the three months ended December 31, 2008 decreased 54 percent to $6.4 million from $13.8 million for the corresponding period in 2007. The decrease for the three months ended December 31, 2008 was primarily attributable to the completion in 2007 of the project funded by Lexicon's award from the Texas Enterprise Fund, reduced revenues under Lexicon's alliance with N.V. Organon, and reduced revenues under Lexicon's neuroscience alliance with Bristol-Myers Squibb resulting from extending the estimated performance period under the agreement to June 30, 2009. For the year ended December 31, 2008, revenues decreased 36 percent to $32.3 million from $50.1 million in 2007.

Research and Development Expenses: Research and development expenses for the three months ended December 31, 2008 decreased 15 percent to $22.8 million from $26.9 million for the corresponding period in 2007. The decrease was primarily attributable to decreased research expenses as a result of the company reallocating resources from genetics research efforts to drug development. For the year ended December 31, 2008, research and development expenses increased four percent to $108.6 million from $104.3 million in 2007.

General and Administrative Expenses: General and administrative expenses for the three months ended December 31, 2008 decreased 17 percent to $4.5 million from $5.3 million for the corresponding period in 2007. The decrease was primarily attributable to lower salary and benefit costs as well as lower stock-based compensation expense. For the year ended December 31, 2008, general and administrative expenses decreased two percent to $20.3 million from $20.7 million in 2007.

Net Loss: Net loss for the three months ended December 31, 2008 was $15.4 million, or $0.11 per share, compared to a net loss of $12.2 million, or $0.09 per share, in the corresponding period in 2007. Net loss for the year ended December 31, 2008 was $76.9 million, or $0.56 per share, compared to a net loss of $58.8 million, or $0.59 per share, in 2007. For the three months ended December 31, 2008, net loss included non-cash, stock-based compensation expense of $1.7 million, compared to $3.1 million in the corresponding period in 2007. For the year ended December 31, 2008, net loss included non-cash, stock-based compensation expense of $6.5 million, compared to $7.9 million in 2007.

Cash and Investments: As of December 31, 2008, Lexicon had $158.8 million in cash and investments, including $16.6 million in cash and investments held by Symphony Icon, as compared to $177.3 million as of September 30, 2008 and $258.8 million as of December 31, 2007.
