Second Quarter Product and Pipeline Highlights

XERMELO® (telotristat ethyl)

  • XERMELO U.S. net sales were $9.0 million in the second quarter of 2020.
  • Telotristat ethyl’s antiproliferative effects observed in a preclinical study in liposarcoma, colon cancer and cholangiocarcinoma cell lines were published online in conjunction with the American Society of Clinical Oncology (ASCO) 2020 annual meeting (May 29 - June 2, 2020).


  • Six posters for sotagliflozin were presented at the virtual 80th American Diabetes Association (ADA) Scientific Sessions (June 12-16, 2020) including additional efficacy and safety data in patients with type 2 diabetes and moderate and severe renal impairment.

Second Quarter 2020 Financial Highlights

Revenues: Revenues for the three months ended June 30, 2020 decreased to $9.2 million from $9.7 million for the corresponding period in 2019, primarily due to a decrease of bulk tablet sales of XERMELO to Ipsen and collaborative revenues, partially offset by an increase in U.S. net product revenue. Net product revenues for the three months ended June 30, 2020 consisted of $9.0 million from net sales of XERMELO in the U.S., up 21% from the prior year quarter. 

Cost of Sales: Cost of sales related to sales of XERMELO for the three months ended June 30, 2020 and 2019 was $0.7 million and $1.3 million, respectively. 

Research and Development (R&D) Expenses: Research and development expenses for the three months ended June 30, 2020 increased to $57.3 million from $12.6 million for the corresponding period in 2019, primarily due to increases in external clinical development costs related to sotagliflozin subsequent to the termination of the alliance with Sanofi.

Selling, General and Administrative (SG&A) Expenses: Selling, general and administrative expenses for the three months ended June 30, 2020 were $14.1 million as compared to $14.3 million for the corresponding period in 2019.

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 Sotagliflozin

Discovered using Lexicon’s unique approach to gene science, sotagliflozin 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. Sotagliflozin 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.
