Fourth Quarter and Full-Year 2018 Financial Highlights

Unless otherwise stated, all comparisons are for the fourth quarter and full year of 2018 compared to the fourth quarter and full year of 2017.

Revenues: Revenues for the fourth quarter decreased to $17.1 million from $34.0 million for the corresponding period in 2017, primarily due to lower revenues recognized under collaboration and license agreements. Full-year 2018 revenues decreased to $63.2 million from $91.7 million, primarily due to timing of revenues recognized from clinical trial activities under the collaboration and license agreements with Sanofi and decreases in milestone payments from Ipsen, partially offset by an increase in net product revenue. Net product revenues for full-year 2018 included $25.0 million and $1.6 million, respectively, from net sales of XERMELO in the U.S. and the sale of bulk tablets to Lexicon’s collaborator, Ipsen.

Cost of Sales: Cost of sales related to sales of XERMELO was $0.6 million and $0.5 million, respectively, for the fourth quarter of 2018 and 2017. Full-year 2018 and 2017 cost of sales was $2.5 million and $1.9 million, respectively.

Research and Development (R&D) Expenses: Research and development expenses for the fourth quarter decreased to $12.3 million from $46.3 million for the corresponding period in 2017, primarily due to decreases in our external clinical development costs relating to sotagliflozin. Full-year 2018 R&D expenses decreased to $100.2 million from $152.2 million, primarily due to lower external clinical development costs relating to sotagliflozin and professional and consulting fees.

Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the fourth quarter were $16.6 million compared to $16.1 million for the same period in 2017. Full-year 2018 SG&A expenses decreased to $63.8 million from $66.1 million, primarily due to lower salaries and benefits, and decreased marketing costs.

Income Tax Benefit: During 2018, there was no income tax benefit. During 2017, Lexicon recognized an $8.7 million income tax benefit when the intangible assets relating to XERMELO were reclassified from indefinite-lived to finite-lived assets. The income tax benefit was remeasured to $12.7 million for full year 2017.

Net Loss: Net loss for the fourth quarter was $16.8 million, or $0.16 per share, compared to a net loss of $26.6 million, or $0.25 per share, in the corresponding period in 2017.

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 in combination with SSA therapy in adults inadequately controlled by SSAs. XERMELO targets tryptophan hydroxylase, an enzyme that mediates the excess serotonin production within metastatic neuroendocrine tumor (mNET) cells. Lexicon has built the in-house capability and infrastructure to launch and market XERMELO in the U.S., where it retains all commercialization rights. Lexicon also retains rights to market XERMELO in Japan. Lexicon has established a license and collaboration agreement with Ipsen to commercialize XERMELO in Europe and other countries outside of U.S. and Japan.

XERMELO was approved by the U.S. Food and Drug Administration on February 28, 2017 and by the European Commission on September 19, 2017 for the treatment of carcinoid syndrome diarrhea in combination with SSA therapy in adults inadequately controlled by SSA therapy. Carcinoid syndrome is a rare condition that occurs in patients living with metastatic NETs (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.

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 Sotagliflozin

Sotagliflozin is an investigational 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.

Lexicon entered into a collaboration and license agreement with Sanofi in November 2015 under which Lexicon granted Sanofi an exclusive, worldwide (excluding Japan), royalty-bearing right and license to develop, manufacture and commercialize sotagliflozin. Lexicon is responsible for all clinical development activities relating to type 1 diabetes and has exercised an exclusive option to co-promote and have a significant role, in collaboration with Sanofi, in the commercialization of sotagliflozin for the treatment of type 1 diabetes in the U.S. Sanofi is responsible for all clinical development and commercialization of sotagliflozin for the treatment of type 2 diabetes worldwide (excluding Japan) and is solely responsible for the commercialization of sotagliflozin for the treatment of type 1 diabetes outside the U.S. (excluding Japan). A New Drug Application and Marketing Authorization Application for sotagliflozin in type 1 diabetes are currently under review at the U.S. Food and Drug Administration and European Medicines Agency, respectively. The product has not yet been approved for use in the U.S., European Union or any other jurisdiction.
