What: Shares of Lexicon Pharamceuticals skyrocketed by over 50% today on massive volume after the tiny biopharma announced that theexperimental drug, oral telotristat etiprate, met its primary endpoint in a pivotal late-stage trial of lowering the average number ofdaily bowel movements in cancer patients withcarcinoid syndrome not adequately controlled by the current standard of care.

Now what: Following these positive top-line results, Lexicon plans on filing oral telotristat etiprate's regulatory application for this indicationwith the U.S. Food and Drug Administration in the near future. Given that the drug was previously granted Fast Track designation by the FDA, it could be on the market as soon as the first-half of 2016, assuming approval.
While the drug's peak sales potential is somewhat fuzzy due to the rare nature of this disorder (typical of orphan drugs in general), oral telotristat etiprate was granted "Orphan Drug Status" by the FDA for this patient population, meaning that it would likely garner a premium pricing structure upon approval.
But perhaps more importantly for investors, at least in the short-term, is the fact that the industry's appetite for gobbling up orphan drugmakers with promising clinical-stage products has gone largely unchecked this year. Lexicon's name is therefore almost certainly going to make its way into the buyout rumor mill in the wake of this positive clinical update. So, stay tuned!
