The Woodlands, Texas, November 7, 2019 - Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), today reported financial results and provided a business update for the three months ended September 30, 2019.

“We continue to make good progress on our XERMELO business, with XERMELO net sales growing more than 30% in the third quarter of 2019 versus the same period in 2018,” said Lonnel Coats, Lexicon’s president and chief executive officer. “We now have full rights for Zynquista. We expect to complete the core Phase 3 studies in type 2 diabetes in the near term and anticipate being in a position to file for regulatory approval for that indication in the U.S. and in Europe in the first half of 2020. We continue to have productive dialogue with the FDA on a path forward for Zynquista in type 1 diabetes in the U.S.”

Third Quarter Product and Pipeline Highlights

XERMELO® (telotristat ethyl)

  • XERMELO U.S. net sales were $8.4 million in the third quarter of 2019.
  • The Telotristat Ethyl for Advanced Biliary Tract Cancer, or TELE-ABC, study, a Phase 2a clinical study of telotristat ethyl in patients with biliary tract cancer, continues to enroll patients.

Zynquista™ (sotagliflozin)

  • In September, Lexicon and Sanofi terminated their alliance for the development and commercialization of sotagliflozin. In connection with the termination, Lexicon regained all rights to sotagliflozin and assumed full responsibility for the worldwide development and commercialization of sotagliflozin in both type 1 and type 2 diabetes. Under the terms of the settlement, Sanofi will pay Lexicon $260 million, of which $208 million was paid in September and the remainder is payable within twelve months. Sanofi continues to coordinate with Lexicon in the transition of responsibility for ongoing clinical studies and other activities.
  • Clinical data for sotagliflozin were highlighted in two oral presentations at the European Association for the Study of Diabetes (EASD) 55th annual meeting (September 16-20; Barcelona, Spain), demonstrating the effect of sotagliflozin on body weight and composition in adults with type 1 diabetes. In addition, five posters were presented, detailing the reductions in glucose variability and risk for hyperglycemia in adults with type 1 diabetes treated with sotagliflozin alone, improved treatment satisfaction in patients with type 1 diabetes treated with sotagliflozin and insulin versus insulin alone, lower rates of clinically relevant hypoglycemic events at any A1C level at 52 weeks in adults with type 1 diabetes, the positive impact of sotagliflozin on renal function, albuminuria and blood pressure in adults with type 1 diabetes and the reduction in markers of arterial stiffness in patients with type 1 diabetes.
  • In September, a post-hoc analysis of hypoglycemia as a function of A1C in patients with type 1 diabetes receiving sotagliflozin or placebo in combination with optimized insulin therapy was published in Diabetes Technology and Therapeutics. The pooled analysis from inTandem1 and inTandem2 trials showed that at 52 weeks, level 1 and 2 hypoglycemia events were 22% to 30% less frequent with sotagliflozin added to optimized insulin therapy versus placebo in adults with type 1 diabetes at any A1C level, with greater differences at lower A1C values.
  • In August, 52-week cardiorenal results from a pooled analysis from the inTandem1 and inTandem2 studies of sotagliflozin in adults with type 1 diabetes were published in Diabetes Care. Sotagliflozin demonstrated changes in clinical biomarkers such as estimated glomerular filtration rate (eGFR), hematocrit, serum albumin, uric acid, systolic blood pressure and urinary albumin-to-creatinine ratio (UACR) that suggest sotagliflozin may reduce cardiovascular risk and progression of chronic kidney disease. Sotagliflozin was associated with short- and long-term renal hemodynamic changes. After cessation of 52 weeks of therapy, eGFR was comparable to baseline and significantly higher than placebo in sotagliflozin-treated patients.
  • In July, Lexicon announced the preliminary topline results received from Sanofi from SOTA-MET, SOTA-CKD3 and SOTA-CKD4, the first three of a total of nine clinical trials included in the core Phase 3 development program for sotagliflozin in type 2 diabetes.

Third Quarter 2019 Financial Highlights

Revenues: Revenues for the three months ended September 30, 2019 increased to $294.4 million from $7.0 million for the corresponding period in 2018, primarily due to an increase of collaborative revenues of $260 million from the termination of the alliance with Sanofi and recognition of the remaining amount of $23.5 million allocated to performance obligations from the initial agreement with Sanofi and an increase in net product revenue. Net product revenues for the three months ended September 30, 2019 consisted of $8.4 million from net sales of XERMELO in the U.S., which were up 33% from the prior year quarter.

Cost of Sales: Cost of sales related to sales of XERMELO for each of the three months ended September 30, 2019 and 2018 was $0.6 million.

Research and Development (R&D) Expenses: Research and development expenses for the three months ended September 30, 2019 increased to $26.7 million from $13.8 million for the corresponding period in 2018, primarily due to an increase in external clinical development costs related to sotagliflozin subsequent to the termination of the alliance with Sanofi, in which Lexicon regained the rights and responsibilities for development and commercialization for sotagliflozin.

Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the three months ended September 30, 2019 decreased to $13.9 million from $15.6 million for the corresponding period in 2018, primarily due to decreased marketing costs.

Impairment Loss on Intangible Asset: An impairment loss for the three months ended September 30, 2019 of $28.6 million was recognized to an indefinite lived intangible asset associated with Lexicon’s 2010 acquisition of Symphony Icon, due to the decision to terminate research and development activities related to a program for irritable bowel syndrome that was among the assets acquired.

Income Tax Benefit: An income tax benefit of $6.0 million for the three months ended September 30, 2019 was recognized in connection with the impairment loss on the indefinite lived intangible asset, which resulted in a decrease to the deferred tax liability and created an income tax benefit.

Net Income (Loss): Net income for the three months ended September 30, 2019 was $226.1 million, or $1.95 per diluted share, as compared to a net loss of $27.4 million, or a loss of $0.26 per share, in the corresponding period in 2018. For the three months ended September 30, 2019 and 2018, net income included non-cash, stock-based compensation expense of $3.6 million and $2.9 million, respectively.

Cash and Investments: As of September 30, 2019, Lexicon had $296.3 million in cash and investments, as compared to $160.1 million as of December 31, 2018. The cash position as of September 30, 2019 includes proceeds of $208 million in connection with the termination of the alliance with Sanofi.

About XERMELO (telotristat ethyl)

Discovered using Lexicon’s unique approach to gene science, XERMELO (telotristat ethyl) is the first and only approved oral therapy for carcinoid syndrome diarrhea. XERMELO targets tryptophan hydroxylase, an enzyme that mediates the excess serotonin production within metastatic neuroendocrine tumor (mNET) cells. XERMELO is approved in the United States, the European Union and certain additional countries for the treatment of carcinoid syndrome diarrhea in combination with somatostatin analog (SSA) therapy in adults inadequately controlled by SSA therapy. Carcinoid syndrome is a rare condition that occurs in patients living with mNETs and is characterized by frequent and debilitating diarrhea. XERMELO targets the overproduction of serotonin inside mNET cells, providing an additional treatment option for patients suffering from carcinoid syndrome diarrhea.

Lexicon has granted Ipsen an exclusive royalty-bearing right and license to commercialize XERMELO outside of the United States and Japan. We are commercializing XERMELO in the United States and Ipsen is commercializing XERMELO in multiple countries, including the United Kingdom and Germany.

XERMELO (telotristat ethyl) Important Safety Information

  • Warnings and Precautions: XERMELO may cause constipation, which can be serious. Monitor for signs and symptoms of constipation and/or severe, persistent, or worsening abdominal pain in patients taking XERMELO. Discontinue XERMELO if severe constipation or severe, persistent, or worsening abdominal pain develops.
  • Adverse Reactions: The most common adverse reactions (≥5%) include nausea, headache, increased gamma-glutamyl-transferase, depression, flatulence, decreased appetite, peripheral edema, and pyrexia.
  • Drug Interactions: If necessary, consider increasing the dose of concomitant CYP3A4 substrates, as XERMELO may decrease their systemic exposure. If combination treatment with XERMELO and short-acting octreotide is needed, administer short-acting octreotide at least 30 minutes after administering XERMELO.

About Zynquista (sotagliflozin)

Discovered using Lexicon’s unique approach to gene science, Zynquista is an oral dual inhibitor of two proteins responsible for glucose regulation known as sodium-glucose co-transporter types 1 and 2 (SGLT1 and SGLT2). SGLT1 is responsible for glucose absorption in the gastrointestinal tract, and SGLT2 is responsible for glucose reabsorption by the kidney. Zynquista is approved in the European Union (EU) for use as an adjunct to insulin therapy to improve blood sugar (glycemic) control in adults with type 1 diabetes with a body mass index ≥ 27 kg/m2, who could not achieve adequate glycemic control despite optimal insulin therapy. Outside of such approval, Zynquista is investigational and has not been approved by any other regulatory authority for type 1 or type 2 diabetes.
