LEXICON PHARMACEUTICALS ANNOUNCES ADDITIONAL DATA ON TELOTRISTAT ETHYL’S ANTIPROLIFERATIVE EFFECTS IN PATIENTS WITH CARCINOID SYNDROME
THE WOODLANDS, Texas, March 13, 2020 (GLOBE NEWSWIRE) -- (Nasdaq: LXRX), announced today additional data on XERMELO’s® (telotristat ethyl) antiproliferative effects in patients with carcinoid syndrome that were presented at the European Neuroendocrine Tumor Society (ENETS) meeting (March 11-13). XERMELO is approved for the treatment of carcinoid syndrome diarrhea in combination with somatostatin analog (SSA) therapy in adults inadequately controlled by SSA therapy, but is not currently approved for any other use.
Data from a retrospective, pre- and post-design chart review of 200 metastatic neuroendocrine tumor patients who were on standard background therapies and received telotristat ethyl for an average of 12 months in US clinical practice demonstrated that most patients had no tumor progression at 6, 12 and 18 months following initiation of telotristat ethyl, with a median time to tumor progression (TTP) of 39.8 months. The majority of patients also experienced progression-free survival (PFS) in the post-telotristat ethyl period, with a median PFS of 23.7 months. In addition, in a subset of 22 patients with recorded biomarker data, mean serotonin levels decreased significantly in the post-telotristat ethyl period. Patients also improved on carcinoid syndrome (CS) symptoms, body weight and performance status.
“We are pleased this observational study showed that use of telotristat ethyl was associated with not only neuroendocrine tumor control but also meaningful improvements in CS symptoms and clinical indicators of overall health in patients with advanced neuroendocrine tumors and carcinoid syndrome,” said Pablo Lapuerta, executive vice president and chief medical officer of Lexicon. “Results of this observational study coupled with preclinical data support the conduct of clinical trials to examine telotristat ethyl’s effect on neuroendocrine tumors.”
About XERMELO (telotristat ethyl)
Discovered using Lexicon’s unique approach to gene science, XERMELO 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 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. Lexicon is 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.
