Thanks, Peter and good morning, everyone. As Peter said, LINZESS demonstrated continued strong demand growth year-over-year. Total LINZESS volume growth included a greater than 20% increase in capsules and a 17% increase in total prescriptions year-on-year. The difference between the two is accounted for by the increased size of the prescription. Similar to what we've seen with LINZESS in previous first quarters and with many other branded primary care drugs, prescription growth was a bit lighter in the first quarter due to seasonality in the market which is caused by patients changing their health plans at the beginning of the year and patients working through annual deductibles. You can see this more clearly through the LINZESS rejection and refusal data. As expected in January, there is typically a sharp increase in rejections and refusals, which returns to normal level over the first quarter. This pattern is consistent with every first quarter since launching LINZESS, except 2016 due to a couple of big managed care wins with CVS in the United Healthcare that began January 1, 2016, and offset this normal seasonality. Importantly, the most recent weekly prescribing data showed the largest week-on-week prescription growth since the beginning of the year, and this acceleration has continued through the early part of the second quarter. We believe LINZESS is just scratching the surface of its potential. In over four years on the market, LINZESS been prescribed by nearly 180,000 physicians to nearly 1.5 million patients with over 40 million adults in the US estimated to suffer from IBS-D the and chronic constipation and the majority of whom are in OTC treatments and dissatisfied, the opportunity to drive further growth is significant. As a branded prescription market leader, we are investing into the brand and building a franchise that we believe will exceed $2 billion in peak annual US sales. We expect to do this by continuing to grow the overall market as well as increase market share, ensure broad peer access and expanding the clinical utility. For example, we recently introduced a third LINZESS dose, the 72 microgram dose for adults with chronic constipation. We are very encouraged by the early uptake in the market and the fact that more than 70% of patients treated with the 72 microgram dose are new LINZESS patients previously taking OTCs. The strong performance validates what we heard from physicians, which is that dosing flexibility is important to help treat this large and heterogeneous chronic constipation population. Turning to our gout franchise. We continue to make progress in developing the market with our first lesinurad product ZURAMPIC. We expect net sales to be nominal in 2017 as we focus on market development, including educating physicians or recognize uncontrolled gout and introducing the efficacy and safety of lesinurad plus allopurinol for appropriate patients, while we secure payer access. We are monitoring certain metrics to assess our progress across all these areas and plan to update you moving forward. Specifically regarding physicians, our focus is on the breadth of the ZURAMPIC prescriber base and the responsiveness to brand promotion. Our sales team is currently calling on roughly 30,000 high prescribing physicians, most of whom are primary care physicians who we believe will be the primary growth driver for years to come. Regarding payers, we are working to secure peer access and reimbursement, so the estimated 2 million uncontrolled gout patients can get ZURAMPIC at a reasonable co-pay. We've had some early wins and our parent team will continue to work on this throughout the remainder of 2017 and into 2018. We believe DUZALLO, the fixed-dose combination of lesinurad and allopurinol will be the critical growth driver behind the lesinurad franchise, helping it to grow to over 300 million in US sales. DUZALLO provides the potential for just one pill once a day, which is one co-pay to enable nearly twice as many uncontrolled gout patients reach goal compared to allopurinol alone. We expect DUZALLO to be approved this fall with the launch soon after approval. Before I close, I just want to comment that we've had a very productive Digestive Disease Week. As the branded prescription market leader, LINZESS has had a big presence and we're having some great conversations with gastroenterologists about the management of IBS-D, chronic constipation, and visceral pain associated with the number of GI disorders. Equally as exciting are the advancements in science that our teams are bringing to the GI community, including Linaclotide DR1 and DR2. IW-3718 for uncontrolled GERD and IW-1701 for achalasia, all of which reinforce our commitment to innovation and fit well into our commercial model. With that, I'll now turn the call over to Mark Currie.
