Thanks, Rick. I will start with TD-1473, our novel important [ph] early administered and intentionally restricted JAK inhibitor. 1473 is being developed to treat a range of inflammatory bowel diseases including ulcerative colitis and debilitating disease of the lining of the colon that affects roughly 700,000 patients a year in the U.S. Our goal is to develop a treatment option for ulcerative colitis and other inflammatory bowel diseases with a highly favorable therapeutic index and a clinically meaningful benefits. Our JAK inhibitors are designed to remain localized in the intestine to minimize exposure in the systemic circulation and to avoid immunosuppressive liability. This represents a potential novel approach to treating ulcerative colitis, including the potential to be used in patients earlier in the course of a disease, ahead of injectable biological agents. In October, we dose the first patients in our Phase 1b trial of 1473 in moderate to severe ulcerative colitis. This follows the successful completion of the phase 1a single and multiple ascending dose studies in healthy volunteers. The primary aim of the Phase 1b patient study is to evaluate the safety and tolerability of 1473, as well as to measure the drug levels in the blood following oral administration. An important secondary objective of the trial is to evaluate the early effects of 1473 on a range of relevant ulcerative colitis biomarkers, technological improvements, and measures of both endoscopic and clinical improvements. The findings from this Phase 1b trial will inform our future clinical development plans for 1473. We expect data from the Phase 1b trial to be available in mid-2017. The totality of the safety and PK data generated in the program to date provide support for our strategy of targeting JAK inhibition to inflamed tissues within the intestinal tract in order to achieve desired therapeutic results for the favorable safety and tolerability profile. We’re also developing TD-3504, a seconds JAK inhibitor compound that is chemically distinct from 1473. 35 of four is an innovative Prodrug that is specifically designed to release active Tofacitinib directly into the large intestine to target the inflammation in the wall of the colon. Our plan is to initiate a Phase 1b trial of 3504, in ulcerative colitis patients in the first half of 2017. Now turning to our NEP inhibitor program, our goal is to develop a medicine that has broad potential to be combined with complimentary mechanisms to treat chronic heart failure, as well as other serious cardiovascular and renal diseases. TD-0714 is the lead molecule in on NEP inhibitor program. This year we reported favorable safety PK and biomarker data from Phase 1 single and multiple ascending dose studies of 714 in healthy volunteers. The results demonstrated sustained target engagements, very low levels of renal elimination of favorable safety and tolerability profile and the potential for once-daily dosing. As we’ve noted, non-renal clearance is especially important because a significant number of patients with cardiac and renal disease that may benefit from mechanization also have compromised renal function. And drugs that are renally cleared, such as a NEP inhibitor and Entresto, have the potential to accumulate, increasing the risk of unwanted side effects and/or requiring dose adjustment. In our NEP inhibitor program, the strategy is to pursue development pathways with a clinical need and the commercial opportunity the greatest. Given the potential therapeutic breadth of our NEP inhibitor program, including the ability to combine with complementary mechanisms of action, we intend to explore both acute and chronic indications. With our existing focus and commercial expertise in the acute care market segments, we believe that acute heart failure is an indication for which we could develop and commercialize a best-in-class intravenous formulation of 714 as a monotherapy. To that end, we plan to initiate a Phase 1 IV study of 714 in healthy volunteers in early 2017. In the chronic setting opportunities to treat chronic heart failure and chronic kidney disease of both mechanistically compelling. And for these indications, our objective is to partner the asset. Consistent with our philosophy of evaluating more than one method in Phase 1, we’ve also progressed to the second NEP inhibitor TD-1439 in the Phase 1 single and multiple ascending dose studies in healthy volunteers and data from these studies are expected in the first half of 2017. Next, I’d like to touch on the positive data we recently announced from two pivotal Phase 3 efficacy studies of Revefenacin. Our investigational nebulized once-daily long-acting muscarinic antagonist or LAMA for the treatment of COPD. Both Phase 3 studies met their primary efficacy endpoints, demonstrating statistically significant and clinically meaningful improvements in trough lung function for both doses of renaissance, up to 12 weeks of dosing, The studies also demonstrated that the 88 and 175 microgram doses of Revefenacin will generally well tolerated with comparable rates of adverse events and serious adverse events across all treatment groups, active and placebo. In pre-specified pooled analysis, Revefenacin produced increases in trough FEV1 not only in subjects who were using Revefenacin as a body maintenance therapy, but also in the 38% of patients who added Revefenacin on to their existing LABA/ICS or LABA COPD therapy. As we noted in our conference call, discussing the results a few weeks ago we were extremely impressed with the additional bronchodilation seem in the add on subgroup. 90% of whom were already on LABA/ICS. We included this group and indeed we’re encouraged to do so, by the FDA, because Renaissance may play an important role as an add-on therapy. With patients continuing to experience additional benefits when lambda is added to either LABA, or LABA/ICS. That just been shown with dual and triple therapy in the handheld COPD markets. Equally important to the bronchodilator effect seen in those even bother to allow the ICS at the scene shown with Joel and Triple therapy in the handheld COPD markets. Equally important to the bronchodilator effects seen in those patients who do not use a background with LABA or LABA/ICS. We are delighted with these impressive results, which underscore Revefenacin's potential to benefit a range of suitable patients for whom a nebulized therapy is required or preferred regardless of whether this is a first long-acting bronchodilator or whether Revefenacin is added to their existing maintenance treatment. The next step in the Revefenacin program is to complete our ongoing twelve-month Phase 3 safety trial. That study has three arms including the 88 and 175 microgram doses of Revefenacin and tiotropium as a control arm. The safety study is fully enrolled and we expect to finish the one year dosing period and complete the study in 2017. The combined benefits from all three studies will inform our final assessment of the efficacy and safety of each dose and provide the basis for all planned NDA submission by the end of 2017. Now I’d like to turn the call over to Renee to provide a financial update.
