Lexicon Pharmaceuticals, Inc. announced that the U.S. Food and Drug Administration has accepted for filing the New Drug Application for telotristat etiprate, an oral drug for the treatment of carcinoid syndrome. The FDA has granted a Priority Review of the NDA filing and set a Prescription Drug User Fee Act (“PDUFA”) target action date of November 30, 2016.
“The granting of priority review by the FDA underscores the need for improving the lives of the patients and caregivers who live with carcinoid syndrome on a daily basis,” said Lexicon President and Chief Executive Officer, Lonnel Coats. “If approved, telotristat etiprate would be the only approved therapy for patients who are no longer able to control their carcinoid syndrome with the current standard of care alone.”
Carcinoid syndrome is a rare disease affecting thousands of cancer patients with metastatic neuroendocrine tumors (mNETs) that have spread to the liver and other organs from the gastrointestinal tract. The condition is characterized by frequent and debilitating diarrhea that often prevents patients from leading active, predictable lives, as well as facial flushing, abdominal pain, fatigue and, over time, heart valve damage.
About Telotristat Etiprate
Discovered using Lexicon’s unique approach to gene science, telotristat etiprate is the first investigational drug in clinical studies to target tryptophan hydroxylase, an enzyme that triggers the excess serotonin production within mNET cells that leads to carcinoid syndrome. While existing treatments for carcinoid syndrome work to reduce the release of serotonin outside tumor cells, telotristat etiprate works at the source to reduce serotonin production within the tumor cells. By specifically inhibiting serotonin production, telotristat etiprate seeks to control this important driver of carcinoid syndrome and, in turn, provide patients with more control over their disease.
Telotristat etiprate has received Fast Track and Orphan Drug designation from the U.S. Food and Drug Administration.
Lexicon retains rights to market telotristat etiprate in the U.S. and Japan, and is building the in-house commercial infrastructure to serve the U.S. market. Lexicon has a license and collaboration agreement with Ipsen to commercialize telotristat etiprate in Europe and other countries outside the U.S. and Japan.
