Lexicon Pharmaceuticals Announces Publication of New XERMELO® (Telotristat Ethyl) Data in Clinical Therapeutics
Significant Dose-Dependent Effects on Changes in Weight Gain and Biochemical and Metabolic Parameters
Improvements in Diarrhea Severity and Nutritional Status
THE WOODLANDS, Texas, May 04, 2018 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq:LXRX), announced today that new XERMELO® (telotristat ethyl) data from the randomized, double-blind, placebo-controlled Phase 3 TELESTAR (Telotristat Etiprate for Somatostatin Analog Not Adequately Controlled Carcinoid Syndrome) study were published in Clinical Therapeutics.
The March issue of Clinical Therapeutics provides the first report of the effects of XERMELO on changes in weight in patients with neuroendocrine tumors (NETs) and carcinoid syndrome that participated in the TELESTAR study. Of the 120 patients with weight data available, up to 32.5% of patients treated with XERMELO experienced significant, dose-dependent weight gain (≥3% from baseline). Only 5.1% of patients on placebo experienced weight gain. Importantly, patients with weight gain experienced improvement in carcinoid syndrome control, as seen in reduction of bowel movement frequency and in parameters of nutritional status associated with positive changes in patient-reported outcomes compared with patients with stable weight or weight loss. Those patients also experienced reduced u5-HIAA levels. Patients with weight gain also experienced fewer serious adverse events than patients with stable weight or weight loss.
“Today’s publication provides a key perspective on the importance of adding XERMELO to somatostatin analog therapy in the treatment of carcinoid syndrome diarrhea,” said Pablo Lapuerta, M.D., executive vice president and chief medical officer of Lexicon. “Treatment with XERMELO helps to address a serious health need for patients, particularly those impacted by the ramifications of carcinoid syndrome diarrhea such as weight loss and malnutrition.”
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 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.
