Thanks, Mary. Good morning, everyone. Ironwood is off to a strong start in 2014, as we made substantial progress in the past quarter across all aspects of our strategy to build a leading GI therapeutics company. As you recall, the tenants of our strategy are, first, maximizing LINZESS, second, leveraging our strong commercial capabilities, third, advancing our robust GI pipeline, and fourth, prioritizing investments on our key value drivers. We have made important progress in each of these areas in the past quarter and I believe we are prime for further advances as this year unfold. Before I turn the call over to Tom, I want to share a few highlights of the quarter. LINZESS continues to demonstrate healthy growth, with net sales reported by far to $60.8 million, up 19.9 -- up 19% quarter-over-quarter, with nearly 240,000 prescriptions up 11% quarter-over-quarter. We believe our recently launched multi-channel, direct-to-consumer patient awareness campaign, which Tom will talk about in a moment, will help us reach more of our target patient population and further accelerate prescription growth. On the IP front, we and Forest received notices of allowance for two separate patent applications covering the commercial formulation of LINZESS and methods of using it to treat patients with IBS-C or CIC. Both of these patent applications are expected to issue in mid-2014 and extend LINZESS patent protection for another five years from 2026 into 2031. In addition, we continue to make advance across our robust GI pipeline. For example, in the first quarter we initiated dosing of IW-3718, in a Phase IIa clinical trial for patients with GERD symptoms who have not responded adequately to treatment with a proton pump inhibitor. Turning to the rest of the world, our partners are making progress in our shared effort to help millions of adult patients suffering from chronic abdominal pain and constipation associated with IBS-C. In Europe, our partner Almirall has launched an appetite, marketed there as CONSTELLA in 10 countries, most recently in Italy and they plan further launches in additional European countries this year. Almirall and Forest recently received marketing approval for Linaclotide in New Mexico and in Canada as well, with both launches expected in midyear. Unfortunately, in Germany, Almirall has not reached agreement with the German pricing authority on a reimbursement price that reflects the innovation and value of CONSTELLA. As a result, they expect the sustain commercialization in Germany in May pending completion of that process. We continue to focus on efficiently running our business, while making discipline and appropriate investments to deliver on our strategy. We are also very appreciative of the strong investor interest that contributed to the successful completion of our common stock offering in February that raise net proceeds of $190 million. With that, I'll hand it over to Tom for the commercial update.
