Lexicon Pharmaceuticals Reports on Clinical Program Status and 2011 First Quarter Results

THE WOODLANDS, Texas, May 3, 2011 /PRNewswire/ -- 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 ended March 31, 2011.  

"Our pipeline of first-in-class drugs continues to make significant progress.  Results from a mechanistic study of a tablet formulation of LX4211 in diabetes patients provided further confirmation of the drug's unique dual mechanism of action, and preparations to initiate a Phase 2b study of LX4211 in the second quarter are on track," said Dr. Arthur T. Sands, president and chief executive officer of Lexicon.  "In addition, we anticipate completing enrollment in the U.S. Phase 2a clinical trial of LX1032 in patients with carcinoid syndrome in the second quarter, with results expected shortly thereafter."

Key Progress in Clinical Pipeline

  • Lexicon reported data from a clinical trial and mechanistic study of a solid oral tablet formulation of LX4211, a dual inhibitor of sodium-glucose cotransporters 1 and 2, showing that LX4211 significantly increased GLP-1 (total and active) and PYY, important mediators of glycemic and appetite control.  The drug also produced rapid and significant improvement in post-prandial glucose (PPG) and fasting plasma glucose (FPG), consistent with results observed in the previously completed Phase 2a study of a liquid formulation of LX4211.  Pharmacokinetic and pharmacodynamic data from the study indicated that the solid oral formulation and the liquid formulation were comparable in key parameters of hormonal release, PPG and FPG.  Lexicon expects to initiate a Phase 2b study of the tablet formulation in the second quarter of this year.
  • Lexicon commenced a Phase 1 study of LX1033, a back-up compound to LX1031 that in vitro studies indicate has the potential to be significantly more potent than LX1031.  LX1031 and LX1033 are each serotonin synthesis inhibitors that act locally in the gastrointestinal tract to reduce serotonin production by inhibiting tryptophan hydroxylase, a key enzyme in the biosynthesis of serotonin.  Lexicon anticipates completing the Phase 1 study of LX1033 in the third quarter of this year.
  • Lexicon expects to initiate a dose-ranging study in the third quarter of this year to explore higher doses of LX2931 in rheumatoid arthritis patients.  Previously reported Phase 2a results of LX2931, an inhibitor of sphingosine-1-phosphate lyase, demonstrated a favorable safety profile at all doses tested and suggested that rheumatoid arthritis patients treated with 150 mg of LX2931 once daily showed improvement in the primary efficacy endpoint of the study, the percentage of patients achieving an American College of Rheumatology 20 (ACR20) response at week 12.
  • Lexicon continued to enroll carcinoid syndrome patients in a U.S.-based Phase 2a clinical trial of LX1032, an inhibitor of tryptophan hydroxylase that reduces peripheral serotonin production without affecting brain serotonin levels, and anticipates completing enrollment in the second quarter of this year and releasing results shortly thereafter.  Lexicon also continued to enroll carcinoid syndrome patients in a second E.U.-based open-label clinical trial of LX1032.

  • Financial Results Revenues:  Lexicon's revenues for the three months ended March 31, 2011 decreased 64 percent to $0.6 million from $1.6 million for the corresponding period in 2010.  The decrease for the three months ended March 31, 2011 was primarily attributable to reduced revenues under Lexicon's alliance with Taconic Farms.

    Research and Development Expenses:  Research and development expenses for the three months ended March 31, 2011 increased 13 percent to $23.9 million from $21.1 million for the corresponding period in 2010.  The increase was primarily attributable to increased external clinical and preclinical research and development costs and increased severance costs resulting from Lexicon's continued reallocation of resources from earlier-stage research towards its most advanced drug discovery and development programs.  

    Increase in Fair Value of Symphony Icon Purchase Liability:  In connection with the acquisition of Symphony Icon, Lexicon made an initial estimate of the fair value of the liability for the associated base and contingent payments.  Changes in this liability, based on the development of the programs and the time until such payments are expected to be made, are recorded in Lexicon's consolidated statements of operations.  The increase in fair value of the Symphony Icon purchase liability was $1.1 million for the three months ended March 31, 2011.  

    General and Administrative Expenses:  General and administrative expenses for the three months ended March 31, 2011 decreased 14 percent to $4.8 million from $5.5 million for the corresponding period in 2010.  The decrease was primarily attributable to decreased legal and patent fees.Consolidated Net Loss:  Net loss for the three months ended March 31, 2011 was $29.6 million, or $0.09 per share, compared to a net loss of $26.1 million, or $0.13 per share, in the corresponding period in 2010.  For the three months ended March 31, 2011, net loss included non-cash, stock-based compensation expense of $1.5 million, compared to $1.3 million in the corresponding period in 2010.Cash and Investments:  As of March 31, 2011, Lexicon had $188.9 million in cash and investments, as compared to $211.1 million as of December 31, 2010.  

    Lexicon Conference Call:Lexicon management will hold a conference call to discuss financial results for the first quarter of 2011 and program status at 11:00 a.m. Eastern Time on May 3, 2011.  The dial-in number for the conference call is 888-220-1244 (within the US/Canada) or 706-679-5615 (international).  The conference ID for all callers is 62216935.  An archived version of the conference call will be available on Lexicon's corporate website at through May 31, 2011.
