Lexicon Pharmaceuticals, Inc. Provides Clinical Pipeline Update And Reports 2014 First Quarter Financial Results

THE WOODLANDS, Texas, May 8, 2014 /PRNewswire/ -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), a biopharmaceutical company focused on developing breakthrough treatments for human disease, today updated its drug development progress and reported financial results for the three months ended March 31, 2014.

"Consistent with our focus on late-stage drug development, we have made continued, excellent progress in the enrollment of patients in our pivotal Phase 3 trial for telotristat etiprate for carcinoid syndrome," said Dr. Arthur T. Sands, president and chief executive officer of Lexicon. "We are also looking forward to advancing LX4211 into later-stage development in type 1 diabetes based on the very encouraging results of our recently-completed Phase 2 study."

Progress in Clinical Pipeline

• LX4211: Earlier this month, Lexicon announced positive top-line results in a Phase 2 clinical trial of LX4211, a dual inhibitor of sodium-glucose transporters 1 and 2, in patients with type 1 diabetes. LX4211 achieved the primary endpoint of reducing mealtime insulin use as well as several secondary endpoints, including improved glycemic control. In the placebo-controlled, double-blind, 28-day study, LX4211 reduced the total daily mealtime bolus insulin dose by 32% compared to 6% for placebo (p=0.007), while significantly improving glycemic control with a mean HbA1c reduction of 0.55% in the LX4211-treated group compared to a reduction of only 0.06% with placebo (p=0.002). These results were accompanied by significant improvement in the time spent in a target glucose range of 70-180 mg/dl, a significant reduction in time in hyperglycemic range, and no increase in hypoglycemia. Multiple measures indicated that LX4211 treatment resulted in reduced variability in blood glucose levels. Overall, LX4211 was well tolerated with no discontinuations of study medication due to adverse events. Lexicon plans to meet with the FDA to discuss the potential advancement of LX4211 into Phase 3 development for type 1 diabetes.
• Telotristat etiprate (LX1032): Lexicon made significant progress in the enrollment of carcinoid syndrome patients in a pivotal Phase 3 clinical trial of telotristat etiprate, an inhibitor of tryptophan hydroxylase (TPH) that reduces peripheral serotonin production without affecting brain serotonin levels. Based on the current pace, Lexicon anticipates completing enrollment in the pivotal TELESTAR study by the end of 2014.

Financial Results

Revenues: Lexicon's revenues for the three months ended March 31, 2014 decreased 23 percent to $0.3 million from $0.4 million for the corresponding period in 2013, primarily due to lower revenues from Lexicon's alliance with Taconic Farms.

Research and Development Expenses: Research and development expenses for the three months ended March 31, 2014 increased 18 percent to $24.0 million from $20.3 million for the corresponding period in 2013, primarily due to increases in external clinical research and development costs, as well as severance costs as a result of the restructuring announced in January 2014 as Lexicon focuses its resources on late-stage drug development.

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. For the three months ended March 31, 2014, the fair value of the Symphony Icon purchase liability increased by $1.1 million as compared to an increase of $1.3 million in the corresponding period in 2013.

General and Administrative Expenses: General and administrative expenses for the three months ended March 31, 2014 increased 31 percent to $5.7 million from $4.3 million for the corresponding period in 2013, primarily due to severance costs as a result of the restructuring announced in January 2014.

Consolidated Net Loss: Net loss for the three months ended March 31, 2014 was $30.8 million, or $0.06 per share, compared to a net loss of $26.0 million, or $0.05 per share, in the corresponding period in 2013. For the three months ended March 31, 2014 and 2013, net loss included non-cash, stock-based compensation expense of $2.3 million and $2.1 million, respectively.

Cash and Investments: As of March 31, 2014, Lexicon had $98.4 million in cash and investments, as compared to $129.1 million in cash and investments as of December 31, 2013.
