XERMELO® (telotristat ethyl) U.S. Quarterly Net Sales Reach $5.3 Million

Conference Call and Webcast Today at 8:00 am EST / 7:00 am CST

The Woodlands, Texas, November 8, 2017 - Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX), today reported financial results for the three months ended September 30, 2017 and provided an overview of key milestones for the company’s commercial product, XERMELO® (telotristat ethyl), and its pipeline drug candidates.

“We had a very busy and productive third quarter with strong operational performance across all aspects of our business, including the achievement of several important milestones. We made significant progress in growing our prescriber base and providing access to XERMELO. This momentum, along with the launch of XERMELO in the U.K. and Germany, supports our confidence in the long-term outlook on the commercial business,” said Lonnel Coats, Lexicon’s president and chief executive officer. “XERMELO is a significant franchise for us, and we are extremely excited about exploring the use of telotristat ethyl in additional therapeutic indications where the role of serotonin inhibition has shown preclinical promise. In parallel, we and Sanofi are making good progress towards advancing sotagliflozin to market in type 1 diabetes. Lastly, we continue to advance our earlier-stage product candidates in areas we believe will create substantial long-term value for the company.”

About XERMELO (telotristat ethyl)

Discovered using Lexicon’s unique approach to gene science, XERMELO (telostristat ethyl) is the first and only approved oral therapy for carcinoid syndrome diarrhea in combination with somatostatin analog (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 a new 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.
