“A new drug application (NDA) has been submitted to the FDA for telotristat etiprate as a treatment for carcinoid syndrome in patients with metastatic neuroendocrine tumors (NETs), according to a statement from the drug’s developer, Lexicon Pharmaceuticals.
“The application was based on data from two phase III trials, both of which demonstrated significant reductions in the frequency of daily bowel movements with telotristat etiprate versus placebo. In the first study, TELESTAR, telotristat etiprate reduced daily bowel movements by up to 35%. In the second study, TELECAST, there was also a significant reduction in bowel movements (P ≤.004), although the exact data were not yet released.
“The FDA will review the NDA within 60 days of submission, at which point the agency will assign a review deadline under the Prescription Drug User Fee Act. Lexicon requested a priority review for the NDA, which would provide a 6-month deadline if the designation is granted.”

“Lexicon Pharmaceuticals, Inc.’s (Nasdaq: LXRX) telotristat etiprate was shown to have clinical benefit in treating carcinoid syndrome in cancer patients not adequately controlled by long-acting somatostatin analog (SSA) therapy, the current standard of care, according to data from the Phase 3 TELESTAR study presented today at the European Cancer Congress in Vienna, Austria.
“Telotristat etiprate, Lexicon’s most advanced product candidate, met the study’s primary endpoint with clinically meaningful reductions in bowel movement frequency in patients whose condition was not adequately controlled by SSA therapy. Carcinoid syndrome is characterized by frequent and debilitating diarrhea that often prevents patients from leading active, predictable lives, as well as by facial flushing, abdominal pain, heart valve damage and other serious consequences.
” ‘We are pleased with the efficacy and safety results of telotristat etiprate and also with the durability of the response shown in this study,’ said Lexicon Executive Vice President and Chief Medical Officer Pablo Lapuerta, M.D. ‘The data also support that the compound is acting directly on the cause of carcinoid syndrome, by reducing serotonin production within tumor cells.’ “
“Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that the pivotal TELESTAR Phase 3 clinical trial met its primary endpoint, showing the benefit of oral telotristat etiprate in treating cancer patients with carcinoid syndrome that is not adequately controlled by the current standard of care. Telotristat etiprate was discovered using Lexicon’s gene science, based on Nobel Prize-winning technology, and is the company’s first discovery to complete a pivotal Phase 3 clinical trial. If approved, telotristat etiprate would be the first oral treatment successfully developed for carcinoid syndrome and the first addition to the standard of care in more than 16 years.
“Top-line results from the Phase 3 study show that patients who added telotristat etiprate to the standard of care at both the 250 mg and 500 mg doses experienced a statistically significant reduction from baseline compared to placebo in the average number of daily bowel movements over the 12-week study period (p<0.001), meeting the study’s primary endpoint.
“ ‘We are extremely pleased with these top-line results,’ said Lexicon President and Chief Executive Officer Lonnel Coats. ‘Carcinoid syndrome is severely debilitating, preventing many patients from leading active and predictable lives, and unfortunately, a majority of patients will not be adequately controlled over time with the current standard of care. We are committed to working closely with the FDA to file our first new drug application (NDA) and to bring this innovative new treatment to patients whose lives are already impacted by the challenges of cancer.’ “
