Lexicon Pharmaceuticals Announces Pivotal TELESTAR Phase 3 Clinical Trial Met Primary Endpoint

Lexicon Pharmaceuticals, Inc. 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[1]. 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. See full press release
